Alternative Splicing Variation: Accessing and Exploiting in Crop Improvement Programs. | LitMetric

AI Article Synopsis

  • Alternative splicing (AS) is a key gene regulatory process that produces multiple mRNAs from a single precursor mRNA, increasing the complexity of plant gene expression and protein diversity.
  • New technologies like next-generation sequencing and bioinformatics allow researchers to study how AS contributes to plant traits such as growth, reproduction, and stress tolerance, especially in relation to domestication and environmental changes.
  • Understanding and cataloguing AS variations can lead to improvements in crop resilience and productivity, which is essential for enhancing food quality and adapting to climate challenges.

Article Abstract

Alternative splicing (AS) is a gene regulatory mechanism modulating gene expression in multiple ways. AS is prevalent in all eukaryotes including plants. AS generates two or more mRNAs from the precursor mRNA (pre-mRNA) to regulate transcriptome complexity and proteome diversity. Advances in next-generation sequencing, omics technology, bioinformatics tools, and computational methods provide new opportunities to quantify and visualize AS-based quantitative trait variation associated with plant growth, development, reproduction, and stress tolerance. Domestication, polyploidization, and environmental perturbation may evolve novel splicing variants associated with agronomically beneficial traits. To date, pre-mRNAs from many genes are spliced into multiple transcripts that cause phenotypic variation for complex traits, both in model plant and field crops. Cataloguing and exploiting such variation may provide new paths to enhance climate resilience, resource-use efficiency, productivity, and nutritional quality of staple food crops. This review provides insights into AS variation alongside a gene expression analysis to select for novel phenotypic diversity for use in breeding programs. AS contributes to heterosis, enhances plant symbiosis (mycorrhiza and rhizobium), and provides a mechanistic link between the core clock genes and diverse environmental clues.
