Abstract
Sustainable crop development aims to maintain or increase yields while reducing environmental impact and managing the challenges imposed by climate change. As the global population grows and arable land becomes scarcer, the integration of molecular breeding with bioinformatics has emerged as an effective strategy for long-term crop improvement. Bioinformatics enables researchers to analyze and interpret the vast quantities of genetic data generated by high-throughput sequencing, making it possible to identify molecular markers, candidate genes, and regulatory networks linked to specific agronomic traits, which breeders then translate into focused, ecologically sustainable breeding programs. This approach has enabled major progress across several fronts: the identification of genes conferring resistance to biotic stressors (pests, pathogens) and abiotic stressors (drought, salinity, heat); the development of nutrient-efficient, low-input crop varieties; the improvement of agronomic performance and nutritional quality through identification of yield- and quality-related genes; and the conservation and deployment of genetic diversity to safeguard long-term breeding sustainability. By combining genomic data with precision breeding techniques, researchers are developing crops that are better adapted to a growing population and a changing climate, positioning the integration of molecular breeding and bioinformatics as a central pillar of future global food security.
Plant bioinformatics has emerged as a cornerstone of modern plant science by enabling the large-scale analysis and interpretation of genomic and post-genomic data for crop improvement. The rapid advancement of high-throughput sequencing technologies, coupled with powerful computational tools, has transformed traditional breeding approaches into data-driven strategies. Bioinformatics facilitates the identification of genes, quantitative trait loci (QTLs), regulatory networks, and molecular markers associated with agronomically important traits, particularly stress tolerance. Abiotic stresses such as drought, salinity, heat, and cold, as well as biotic stresses caused by pathogens and pests, significantly limit crop productivity worldwide. Integrating bioinformatics with genomics, transcriptomics, proteomics, metabolomics, and phenomics has enabled a deeper understanding of plant stress responses and accelerated the development of resilient crop varieties. This review comprehensively discusses the applications of plant bioinformatics in crop improvement and stress tolerance, highlighting major computational approaches, databases, tools, and emerging trends. The challenges and prospects of bioinformatics-driven plant breeding are also critically examined.

Drought constitutes one of the most pervasive abiotic constraints limiting global crop productivity, with its frequency and intensity projected to increase substantially under ongoing climate change. This narrative review synthesises contemporary evidence on the genetic, physiological, and agronomic dimensions of drought resilience in major food crops, drawing on peer-reviewed literature published primarily between 2000 and 2026. Physiologically, drought impairs stomatal conductance, suppresses photosynthetic carbon assimilation, disturbs osmotic equilibrium, and restricts root-mediated water acquisition, with reproductive stages being disproportionately vulnerable. At the genetic level, the deployment of quantitative trait loci (QTL) mapping, transcription-factor engineering, CRISPR-Cas9 genome editing, and the overexpression of stress-responsive functional genes has opened novel avenues for enhancing tolerance without compromising yield potential. Breeding programmes have increasingly integrated marker-assisted selection (MAS) and genomic selection to accelerate genetic gain, whilst high-throughput phenotyping platforms now enable rapid assessment of drought-adaptive traits at a population scale. Agronomic strategies, including deficit irrigation, conservation tillage, intercropping, and application of plant growth-promoting rhizobacteria (PGPR), provide complementary levers for sustaining productivity under water-limited conditions. Emerging integrative approaches that combine multi-omics, digital precision agriculture, and policy-enabled climate-smart frameworks are highlighted as critical pathways for translating laboratory and field insights into scalable solutions. The review identifies persistent knowledge gaps—including the limited translation of genomic advances to smallholder contexts and the underexplored potential of microbiome engineering—and calls for a convergence of disciplinary expertise, equitable technology transfer, and coherent policy support to achieve drought-resilient food systems globally.

Plant breeding has progressed from phenotype-based selection to increasingly precise genetic and agronomic interventions. Advances in molecular breeding, genome engineering, and crop management have improved productivity, but have also promoted the widespread use of genetically uniform cultivars optimized for controlled production systems. While uniformity facilitates predictability and mechanization, it may constrain adaptive capacity under increasingly variable environmental conditions. In parallel, recent developments in digital agriculture, including high-resolution phenotyping, remote-sensing, molecular diagnostics, and AI-assisted decision support, are transforming the ability to monitor and manage biological variation across spatial and temporal scales. In this review, we examine how these technological advances intersect with emerging concepts in crop diversity and reproductive biology. We discuss how digital agriculture enables improved characterization of genotype-environment interactions and consider reproductive mechanisms that expand the accessible breeding space beyond conventional biparental crossing schemes, including haploid induction and multi-parental breeding. These approaches provide opportunities to accelerate trait introgression, generate novel genetic combinations, and overcome reproductive barriers. We argue that digital and diagnostic agriculture provide an informational framework for the deployment and evaluation of genetically heterogeneous plant populations. Together, recent advances suggest that technological precision and biological diversity can be integrated into breeding strategies that improve productivity and resilience.
Agricultural systems are increasingly challenged by climate change, resource scarcity, environmental degradation, and the need to ensure food security for a growing global population. Addressing these multifaceted challenges requires innovative, science-driven approaches that enhance productivity while promoting ecological sustainability. This editorial examines the evolving role of plant biotechnology as a key driver of modern agricultural advancement, highlighting recent developments in genomics, multi-omics technologies, molecular breeding, genome editing, plant tissue culture, and digital agriculture. It discusses how these technologies contribute to the development of resilient crop varieties with improved tolerance to biotic and abiotic stresses, enhanced nutrient-use efficiency, and superior agronomic performance. The editorial further emphasizes the integration of artificial intelligence, high-throughput phenotyping, bioinformatics, and systems biology into precision crop improvement, enabling more efficient translation of molecular discoveries into field applications. The importance of interdisciplinary collaboration, responsible innovation, biosafety, and science-based regulatory frameworks is also considered in supporting the sustainable deployment of emerging biotechnologies. Looking ahead, the convergence of advanced molecular tools with computational and ecological sciences is expected to accelerate the development of resilient agricultural systems capable of addressing future environmental and food production challenges. Continued investment in research, technological innovation, and international collaboration will be essential to maximize the societal and environmental benefits of next-generation crop improvement strategies.

Plants have been domesticated for thousands of years and subject to human derived selection for desirable traits such as improved yield, disease tolerance, nutrient content, and palatability.Advancements in high-throughput DNA sequencing advancements have allowed researchers to study the diversity of the seed microbiome. We reviewed the literature and identified articles that investigated the impact of domestication on seed microbiome diversity of various plant species.The resultant analysis suggests that the impacts of domestication and selective breeding on seed microbiome diversity are variable and inconclusive due to the low number of independent studies per species and the limited diversity of domesticated species examined. Based upon our analysis we suggest a need for standardized methodology and bioinformatic analysis to accompany further research on seed development of domesticated crop species. Understanding the mechanisms that influence plantmicrobe interactions, such as microbial colonization during seed development, and their applications in sustainable crop improvement is the next step towards innovative and scalable advances in agricultural practice.
