Special Issue Information

Dear Colleagues,

The present scenario of continuous environmental fluctuations poses an unfavorable condition for the survival of plants. Climate-change-inflicted abiotic stresses, along with pathogen and herbivore attacks, account for impaired plant growth and significant yield loss. Therefore, understanding the mechanisms of plant adaptation to these adverse conditions is of paramount importance. In the post genomic era, next-generation sequencing technologies have facilitated the availability of genomes and transcriptomes data that led to functional genomics studies in model and crop plants. The reference genome sequences have enabled the identification of important gene families and their comparative analysis across a spectra of plant species. Genomic approaches are complemented by transcriptomics and dominated by RNA-Seq in recent times, and it has provided information about the gene expression, novel transcripts, alternative splice variants, etc. In addition, molecular breeding methods and GWAS analysis have identified important stress tolerance and yield-related QTLs in crop plants. The recent upsurge of genome editing methods including CRISPR-Cas9 has revolutionized plant functional genomics around the world. This Special Issue invites the submission of original research and review articles providing insights and latest updates on the application and utilization of genomics-based approaches to improve plant adaptation and crop productivity.

In the realm of agriculture, a pressing concern remains the abiotic stresses, such as temperature fluctuation, drought, soil salinity, and heavy metal contamination. These adverse growth conditions hamper crop yields and global food security. In this review, we present a comprehensive examination of the recent advancements in utilizing genomics and transcriptomics, tools to enhance crop resilience against these stress factors. Genomics aids in the identification of genes responsive to stress, unravels regulatory networks, and pinpoints genetic variations linked to stress tolerance. Concurrently, transcriptomics sheds light on the intricate dynamics of gene expression during stress conditions, unearthing novel stress-responsive genes and signaling pathways. This wealth of knowledge shapes the development of stress-tolerant crop varieties, achieved through conventional breeding programs and state-of-the-art genetic engineering and gene editing techniques like CRISPR-Cas9. Moreover, the integration of diverse omics data and functional genomics tools empowers precise manipulation of crop genomes to fortify their stress resilience. In summary, the integration of genomics and transcriptomics holds substantial promise in elucidating the molecular mechanisms behind crop stress tolerance, offering a path towards sustainable agriculture and safeguarding food security amidst shifting environmental challenges.
