Plant resilience against biotic stresses is essential for ensuring food security and sustainable agriculture. Enhanced plant defense mechanisms can significantly reduce crop losses caused by pests and pathogens. Recent advancements in molecular biology and genetic engineering offer novel approaches for bolstering plant immune responses. Plants have evolved sophisticated defense systems, such as pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) and effector-triggered immunity (ETI). Recent studies have highlighted the role of callose synthases, malectin/malectin-like domain-containing receptor-like kinases (MRLKs), and RNA interference (RNAi) in plant immunity. Callose synthase genes, such as GhCalS5 in cotton, have been shown to enhance resistance to cotton aphids by upregulating callose formation, a vital barrier against pathogen invasion. Additionally, MRLKs in soybeans have been demonstrated to play critical roles in modulating PTI and ETI, potentially offering new avenues for enhancing soybean resistance against pathogens like Phytophthora sojae and bacterial blight. Furthermore, RNAi technologies, including Host-Induced Gene Silencing (HIGS) and Spray-Induced Gene Silencing (SIGS), have emerged as promising tools for crop protection. These techniques exploit small RNAs (sRNAs) to trigger silencing of pathogen genes, offering a targeted and environmentally friendly approach to pest and pathogen management. For instance, sRNAs produced by host plants can enter into pathogen cells during invasion, effectively silencing pathogen genes and reducing disease severity.
This Research Topic aims to explore innovative molecular and genetic strategies to enhance plant defense mechanisms against an array of biotic stresses. The main objectives include investigating the roles of callose synthases and MRLKs in plant immunity, advancing RNAi technologies for crop protection, and developing new gene/vector designs for improved plant resistance. Specific questions to be addressed include: How do callose synthases like GhCalS5 enhance resistance to insect pests and pathogens? What are the regulatory mechanisms of MRLKs in PTI and ETI? How can RNAi technologies be optimized for effective pest and pathogen management?
