Strigolactones as Integrative Regulators of Plant Adaptation and Resilience to Abiotic Stress Strigolactones function as central modulators of plant hormonal and stress signalling networks, orchestrating growth, developmental processes and adaptive responses under abiotic stress. Their biosyn....

Schematic diagram showing strigolactone (SL) synthesis from carlactone precursor via distinct pathways to produce canonical or non-canonical SLs; with the latter product produced by CYP722A1, and required for flowering regulation. To the right is an image of the first author, Masaki Kuno.

Kuno et al. show that #Arabidopsis CYP722A1 synthesizes a noncanonical SL that specifically regulates floral transition, suggesting structural diversification of #strigolactones are required for specialized functions in #plantdevelopment

Branching out: Nitrogen-dependent modulation of strigolactone signaling Strigolactones (SLs) are carotenoid-derived plant compounds that stimulate the germination of root-parasitic weeds. Why a host plant should produce such detrimental signals remained unclear until exuded SLs were shown to also encourage symbioses with arbuscular mycorrhizal fungi. Shortly after this discovery, SLs were found to act internally as endogenous phytohormones to regulate numerous traits, most prominently shoot branching, or “tillering” in cereal crops (Gomez-Roldan et al., 2008; Umehara et al., 2008).

Our spotlight paper on nitrogen-dependent regulation of strigolactone signalling is out now! It's a little mini-review on some really cool recent work on the receptor protein D14 in rice. (Featuring a little illustration of rice by yours truly 🌾)

I am pleased to share our latest findings on the strigolactone receptor, D14. Our work reveals alternative mechanisms of SL-induced D14 degradation, independent of MAX2 and SMXL6/7/8. #strigolactones
