RNA splicing in plants

RNA splicing in plants is a crucial step in gene expression where introns are removed from precursor mRNA, creating mature mRNA that can be translated into functional proteins. Unlike animals, plants display a high level of alternative splicing, producing multiple protein variants from a single gene to respond to environmental stresses. This flexibility in gene expression helps plants adapt to changing conditions like drought, temperature shifts, and pathogen attacks. In plants, splicing is governed by spliceosomes—complexes made of small nuclear RNAs and proteins. The regulatory impact of alternative splicing is significant for plant development and resilience, making it a valuable area for research to enhance crop yield and stress adaptation through targeted genetic and molecular techniques.
