Strigolactone, a neglected plant hormone, with a great potential for crop improvement: Crosstalk with other plant hormones

Strigolactones (SLs), initially reported as germination stimulants for Striga lutea were later described for their role in Phelipanche and Orobanche species. SLs were reported in major cereals such as sorghum and maize, which established their importance in host-parasite interaction. Over the past decade, several roles of SLs have been elucidated in root and shoot architecture, pathogen interaction, plant defense mechanism, and nutrition uptake. Additionally, SL plays a key role in abiotic and biotic stress tolerance associated with other phytohormones. The review provides a comprehensive overview of various aspects of SLs and their complex interaction networks with other phytohormones that exist in the plant system. The review also highlights pivotal points for establishing SLs in commercial agriculture to fully explore their potential in crop improvement and shaping modern agriculture.

Automated summary

Strigolactones, initially known as germination stimulants for certain plants, have been found to play crucial roles in various aspects of plant growth and defense. They interact with other phytohormones and are involved in root and shoot architecture, pathogen interaction, and nutrient uptake. Furthermore, Strigolactones have been identified as important factors in abiotic and biotic stress tolerance. This review highlights the importance of understanding Strigolactones and their complex interaction networks for crop improvement and modern agriculture.
