How structural interactions and receptor phosphorylation shape strigolactone signaling in rice.

The phytohormone strigolactone (SL) regulates various developmental processes and plant adaptation to nutrient availability, which in turn regulates strigolactone biosynthesis. In the recent issue of Cell, Hu et al. advance the understanding of the interaction of the SL receptor complex and reveal exciting insights into the nitrogen-dependent regulation of SL signaling and SL-dependent tillering in rice.

The role of hydrolysis in perceiving and degrading the plant hormone strigolactones.

Strigolactones (SLs) perform versatile functions in plants. The different members of the α/β-hydrolase superfamily bind and hydrolyze SLs at varying rates to transduce their signal or maintain SL homeostasis. Recent work by Palayam et al.
