Title : Role of strigolactones in plant- microbe interaction and stress tolerance
Abstract:
Strigolactones (SLs) are important phytohormone that regulate shoot branching, tillering, leaf development, root growth, anthocyanin production, pathogen defense, and resistance to phosphate shortage and drought. Additionally, roots release SLs into the soil, mainly when there is little availability of phosphate or nitrogen. Rhizospheric SLs can promote symbiotic relationships with arbuscular mycorrhizal (AM) fungi as well as the germination of Orobanchaceae root parasite plants. AMF increase the rate at which host plants use mineral resources, particularly phosphorus (P), and enhance plant development and tolerance to a variety of abiotic and biotic challenges. So these facilitated rhizobial symbiosis through SL application are alternative options for reducing synthetic fertilizers and other chemicals, thereby endorsing environmentally sustainable farming. Furthermore, SLs emerged as an exciting target in adapting plants to abiotic stress with several applications in sustainable agriculture. In recent times, functional analysis of genes associated with the bio synthetic pathway and signaling of SL revealed that SLs impart protection against water deficit conditions.
Audience Takeaway:
- How can SLs enhance nutrient assimilation (P uptake) and promote the development of crops in the early stages?
- The sustainable approach for enhancing drought tolerance and nutrient acquisition through SL facilitated microbial symbiosis
- How can SLs play a role in improving drought resilience in crops?
