Decoding alternative splicing: A key player in plant biotic stress resistance.

Area of Science:

• Plant biology
• Molecular biology
• Genetics

Background:

• Alternative splicing (AS) is a key post-transcriptional process in plants, generating functional diversity.
• AS enables plants to adapt to various biotic stresses like bacterial, fungal, and viral infections.
• Bioinformatics advancements have enhanced the study of AS events and their role in plant immunity.

Purpose of the Study:

• To review the critical roles of AS in plant immunity.
• To highlight AS involvement in RNA interference (RNAi), hormone signaling, pattern-triggered immunity (PTI), and effector-triggered immunity (ETI).
• To explore the potential of AS in developing novel pesticides and enhancing crop disease resistance.

Main Methods:

• Literature review of studies on alternative splicing in plant biotic stress responses.
• Analysis of bioinformatics tools for AS event detection and characterization.
• Synthesis of current knowledge on AS regulatory mechanisms in plant immunity.

Main Results:

• AS diversifies gene function, aiding plant adaptation to biotic stresses.
• AS regulates key plant immune pathways, including RNAi, hormone signaling, PTI, and ETI.
• Pathogens can manipulate plant AS to produce effectors that compromise immunity.

Conclusions:

• AS plays a vital role in plant defense against pathogens.
• Targeting AS offers potential for developing new pesticides and improving crop resilience.
• Further research into AS under biotic stress will drive innovation in crop improvement and sustainable agriculture.
