Strigolactones: Biosynthetic regulation, hormonal interaction, and their involvement in abiotic stress adaption

Phytohormones are essential for increasing plant resistance to environmental challenges, such as abiotic stress, which have a detrimental impact on plant production and threat to future food security. Strigolactones (SLs) regulate a variety of vegetative growth and development, and help plants respond to various abiotic stresses. This phytohormone controls root morphology, secondary growth, and shoot branching. Exogenous SLs can be utilized to mitigate adverse abiotic stresses, which may enhance plant output and quality. The purpose of this review is to provide a comprehensive overview of the biosynthesis of SLs as well as their signal transduction pathways, and the interaction of SLs with other phytohormones such as abscisic acid (ABA) and salicylic acid (SA) in plant systems.

Automated summary

Phytohormone strigolactones play a crucial role in regulating and responding to abiotic stresses, enhancing plant resistance through controlling root morphology and secondary growth.
