The Australian Academy of Technological Sciences and Engineering, commonly known as ATSE, elects new Fellows each year on the basis of distinguished contributions across industry leadership, policymaking, research and commercialisation. Unlike academies that honor purely fundamental discovery, ATSE explicitly celebrates the translation of science into technologies, products and policies that deliver measurable benefit to the nation. In its citation for Professor Varshney, the Academy noted his contributions in reshaping the global landscape of agricultural biotechnology and his efforts to translate genomic insights into practical tools for major crops, a distinction that underscores the applied character of his research program.

At the heart of the Academy’s recognition is Professor Varshney’s work on genome-enabled crop improvement, an approach that uses dense genetic maps, whole-genome sequencing and molecular markers to identify the DNA variants underlying traits such as yield, drought tolerance and disease resistance. By locating these variants, breeders can select superior plants at the seedling stage rather than waiting years for plants to mature and express their potential in the field. The Academy highlighted his contribution to the development of high-yielding and climate-resilient crop varieties for growers in Australia, Asia and Africa, noting that in Australia his breakthrough approach has created cost-effective and accessible genomic resources and breeding platforms for wheat, pulses and horticultural crops, accelerating precision breeding across the sector.

The practical significance of these platforms lies in their accessibility. Traditional genomic selection pipelines have often been expensive and technically demanding, placing them beyond the reach of smaller breeding programs and orphan crops that feed much of the developing world. By driving down costs and standardizing the tools required to deploy genomic information, Professor Varshney’s work has allowed breeding teams to compress breeding cycles, increase genetic gain per season and respond more rapidly to shifting environmental pressures, including the hotter and drier conditions that increasingly challenge Australian and international agriculture. The Academy also credited his work with strengthening Australia’s biotechnology capability and supporting grower profitability, sustainability and global competitiveness across the nation’s agricultural sector, which is valued at around 100 billion dollars.

Murdoch University Vice Chancellor Professor Andrew Deeks hailed the election as evidence of excellence spanning the entire research pipeline. In a statement, he remarked that Professor Varshney’s election to ATSE is his third to a leading learned academy in four years, a remarkable achievement that reflects excellence across the full research spectrum, from discovery to application. He noted that since arriving in Australia, Professor Varshney has been a driving force for agricultural research and productivity, working closely with the Federal Government and primary industries departments across the nation on broadacre and horticultural crops research, and that his impact reaches well beyond Australian shores, having benefited millions of smallholder farmers across Africa and South Asia while continuing to inform and guide breeding programs across the globe.

Deputy Vice Chancellor Research and Innovation Professor Peter Eastwood emphasized the breadth of that influence, describing Professor Varshney as widely recognised as one of the world’s leading crop geneticists and a pioneer of genomics resources for Australian crops whose research has also shaped agricultural policy and decision-making across the globe. He said this capacity to translate cutting-edge science into meaningful societal impact reflects Murdoch University’s ambition to deliver research that changes the world, framing the fellowship not only as a personal honor but as an institutional endorsement of the university’s translational research model.

For his part, Professor Varshney described the election as an immense honor and privilege, and used the occasion to issue a pointed message about the pace of agricultural innovation. He said he believes the future of Australian agriculture will depend on how quickly the nation can translate technological innovation into on-farm impact, and that ATSE plays an incredibly important role in shaping that process across industries. He observed that Australia’s agriculture sector is a remarkable success story and that its growers, breeders and the wider industry are not short of good ideas, but that what the sector does have is limited time to turn these ideas into tangible outcomes. ATSE, he argued, is well placed to close this gap, and he looks forward to playing a part in supporting the Academy’s efforts to utilise technology to solve complex challenges.

That sense of urgency reflects a broader scientific consensus that agricultural systems face a narrowing window for adaptation. Rising temperatures, volatile rainfall and evolving pest and disease pressures are compressing the timelines over which new varieties must be developed, tested and deployed. Genomic tools are widely regarded as among the most powerful levers available, because they allow breeders to predict performance early, stack multiple resistance genes into single varieties and mine wild relatives of crops for traits that domesticated gene pools have lost. The challenge, as Professor Varshney’s comments suggest, is less about generating genomic data than about building the institutional pipelines, breeding platforms and policy frameworks that move that data from the laboratory into farmers’ fields at scale.

His career embodies that translation focus. Across roles spanning international agricultural research and, most recently, his leadership of Murdoch University’s crop and food innovation portfolio and the WA State Agricultural Biotechnology Centre, he has championed the idea that genomic science should be judged by its uptake, whether in the breeding programs of major Australian grain and pulse crops or in the fields of smallholder farmers in Africa and South Asia. The triple academy fellowship, spanning the Royal Society’s recognition of fundamental science, the Australian Academy of Science’s honor for research excellence and ATSE’s mandate for technological application, is a rare formal acknowledgment of a career that has spanned all three domains simultaneously.

Professor Varshney will formally join the Academy alongside the other newly elected 2026 Fellows at the New Fellows Showcase, to be held at Allianz Stadium in Sydney on 28 October 2026, an event that introduces the incoming cohort and highlights the technological challenges they have been elected to help solve. For Australian agriculture, his presence within ATSE brings one of the field’s most decorated crop geneticists directly into the national conversation about how technology, policy and industry can be aligned to keep the sector competitive and resilient, and to ensure that the genomic revolution in plant breeding continues to deliver varieties that farmers, in Australia and around the world, can actually grow.

The work, published in The Crop Journal, builds directly on the team’s earlier platform, Crop-GPA 1.0, which modeled associations at the level of whole genes. The new version pushes the resolution down to individual SNPs and extends the modeling across species boundaries, an advance the authors argue is essential for identifying the functional variants that actually drive agronomic traits. In crops, traits such as yield, disease resistance, stress tolerance, and grain quality are shaped by countless small genetic effects scattered throughout the genome. Pinpointing which SNPs matter has traditionally required labor-intensive quantitative trait locus mapping in each species separately, a process that becomes prohibitively slow when applied to the many minor crops that lack deep genomic resources.

That unevenness in genomic knowledge is precisely the problem Crop-GPA 2.0 was engineered to address. Well-studied staples like rice, maize, and wheat benefit from dense SNP catalogs, extensive reference genomes, and large phenotyping datasets, while many orphan crops have only fragments of this infrastructure. Machine-learning models trained on one species have historically performed poorly when applied to another, because the statistical relationships between sequence features and phenotypes do not simply carry over. The research team, led by Professor Zhenyu Yue, sought a framework that could learn generalizable patterns of SNP-trait association from data-rich crops and redeploy that knowledge on data-poor ones, effectively letting genomic insight accumulated in one species pay dividends in many.

Technically, the framework rests on a hierarchical genomic representation strategy that integrates multi-scale DNA sequence and structural features around each candidate SNP. Rather than examining a single base in isolation, the model encodes complementary information at multiple spatial scales, capturing local sequence context as well as broader structural signals in the surrounding genome. According to Yue, this layered representation gives the network a richer description of each variant, making it easier to distinguish SNPs genuinely associated with important traits from the vast background of neutral variation. The design reflects a broader trend in genomics-informed deep learning, where architectural choices that mirror the biological organization of DNA, from codons to regulatory neighborhoods to chromosomal context, consistently outperform flat representations.

On top of this representation sits the framework’s second pillar: cross-species pre-training combined with trait-aware learning. The pre-training stage exposes the model to genomic patterns shared across multiple crop species, allowing it to internalize common regularities in how sequence features encode function. The trait-aware stage then refines these representations for specific phenotypes, retaining the signals that distinguish a disease-resistance SNP from a drought-tolerance SNP. Yue explains that the central design goal was to capture what can be shared across crops without erasing trait-specific information. Yujia Gao, the study’s first author, frames it the same way: by bringing these two levels of information together, the framework offers a more transferable route to decoding genotype-phenotype relationships across diverse crops, instead of treating every species and every trait as an isolated modeling problem.

The practical payoff of this architecture became clear in the evaluation experiments. The researchers tested Crop-GPA 2.0 on representative crops including rice, maize, and wheat, comparing it against existing association-prediction methods across multiple prediction tasks. The framework outperformed its competitors and, critically, retained strong performance in two scenarios that break most conventional models: when knowledge was transferred across species boundaries and when the amount of training data was deliberately reduced. This robustness under data scarcity matters enormously for real-world breeding programs, where labeled phenotype data are expensive and time-consuming to generate. A model that degrades gracefully with limited training data can deliver useful candidate-SNP rankings even in crops where only a handful of well-characterized traits exist.

Predictive accuracy alone, however, is not enough to convince biologists, and the team went a step further by asking whether the model’s high-confidence predictions corresponded to independently documented genetics. They found that the SNPs Crop-GPA 2.0 prioritized were supported by previously reported quantitative trait locus, or QTL, evidence, meaning independent mapping studies had already linked those genomic regions to relevant traits. This external validation is significant because it demonstrates that the network is not simply exploiting statistical artifacts or dataset quirks, but recovering genuine biological signal. A model capable of surfacing trait-relevant variants that align with experimental QTL evidence can serve as a credible triage tool, helping researchers decide which candidates merit expensive follow-up validation.

Gao emphasizes that this combination of computational performance and biological interpretability is what separates Crop-GPA 2.0 from a purely statistical exercise. In her view, the framework provides SNP-level evidence that bridges the gap between association modeling and functional variant discovery, turning a black-box prediction problem into a source of testable hypotheses about the molecular basis of crop traits. For breeders, that bridge is the difference between knowing that a model predicts something and knowing which physical DNA variants to track in a crossing program. Marker-assisted selection and genomic prediction both depend on having shortlists of credible candidate variants, and a framework that produces such shortlists with independent QTL support could accelerate decisions that currently take years of fieldwork.

To broaden access, the team has also deployed an online Crop-GPA 2.0 platform that integrates genotype-phenotype association data with species- and trait-specific SNP prediction, visualization, and interactive analysis. Researchers can query the system rather than assembling the computational pipeline themselves, lowering the barrier for labs without dedicated machine-learning expertise. Looking forward, the authors position the framework as a scalable artificial-intelligence approach for reusing genomic knowledge across crop species, with applications ranging from functional variant discovery and crop functional genomics to precision breeding. As sequencing costs continue to fall and genomic datasets accumulate faster than they can be interpreted, tools that transfer learning across the boundaries of species and data availability may become as fundamental to crop science as the sequencing machines that generate the data in the first place.

The distinction between gene-level and SNP-level modeling carries more weight than it might first appear. A gene is a broad annotation, often spanning thousands of bases and multiple functional elements, whereas a SNP pinpoints a single variable position that may sit in a coding region, a splice site, or a regulatory sequence. For breeding purposes, the finer resolution matters because breeders ultimately work with markers they can assay cheaply and reliably in seed lots. A gene-level association tells a researcher where to look; a validated SNP-level association tells them exactly what to screen for, which is the level of precision that marker-assisted selection pipelines require.

The reliance on QTL evidence as an external check also reflects a long-standing tension in computational genomics. Quantitative trait locus mapping, which links regions of the genome to measured trait variation through controlled crosses or population surveys, has accumulated decades of experimental results across major crops. These mapped regions, however, are typically large, often containing dozens or hundreds of candidate variants, and narrowing them down to causal SNPs has remained a bottleneck. A predictive model whose high-confidence outputs concentrate within known QTL intervals offers a way to prioritize among the many variants those intervals contain, effectively using deep learning as a fine-mapping complement to classical genetic approaches rather than a replacement for them.

The cross-species ambition of the framework also touches on a deeper biological question: how much of the sequence-to-function relationship is conserved between distantly related grasses? Rice, maize, and wheat share common ancestry, and many genes governing flowering, architecture, and stress response have recognizable counterparts across all three. Yet their genomes differ dramatically in size and organization, with wheat alone carrying a polyploid genome several times larger than rice’s. A model that transfers knowledge across such divergent genomic backgrounds must implicitly learn features robust to these differences, which may explain the emphasis on multi-scale representations that capture context beyond any one species’ idiosyncratic genome structure.

There are also practical considerations for adoption. Deep-learning frameworks in agriculture have sometimes struggled to move beyond publications because they demand specialized computational environments and curated inputs. The decision to release an online platform alongside the underlying method suggests awareness of this barrier, allowing researchers to submit prediction tasks without local infrastructure. Whether the community embraces such tools will depend on sustained maintenance, transparent documentation of training data, and honest reporting of the model’s failure modes, particularly for traits and species far removed from the training distribution.

As genomic datasets continue to accumulate unevenly across the world’s crops, approaches that treat accumulated knowledge as a transferable resource rather than a species-specific asset may reshape how quickly minor and under-resourced crops catch up with the major staples.
