TL;DR: In this paper, the authors show that ABA levels in imbibed seeds are elevated at high temperature and that this increase is correlated with up-regulation of the zeaxanthin epoxidase gene ABA1/ZEP and three 9-cis-epoxycarotenoid dioxygenase genes, NCED2,NCED5, and NCED9.
Journal ArticleDOI

TL;DR: It is concluded that ShHTLs function as the strigolactone receptors mediating seed germination in Striga, the diverged family of α/β hydrolase-fold proteins inStriga.
Journal ArticleDOI
Structure-function analysis identifies highly sensitive strigolactone receptors in Striga.

TL;DR: A crystal structure of a highly sensitive strigolactone receptor from Striga revealed an unexpectedly large ligand-binding pocket, which may explain how Striga manages to sense picomolar concentrations of the range of strIGolactones.
Journal ArticleDOI
A small-molecule screen identifies new functions for the plant hormone strigolactone
Yuichiro Tsuchiya,Danielle Vidaurre,Shigeo Toh,Atsushi Hanada,Eiji Nambara,Yuji Kamiya,Shinjiro Yamaguchi,Peter McCourt +7 more
TL;DR: Molecular analysis showed strigolactones regulate the nuclear localization of the COP1 ubiquitin ligase, which in part determines the levels of light regulators such as HY5, which was used to identify rice cultivars with reduced capacity to germinate parasitic seed.
Journal ArticleDOI
Thermoinhibition uncovers a role for strigolactones in Arabidopsis seed germination
TL;DR: It is reported that thermoinhibition, which involves exposing seeds to high temperatures, uncovers a clear role for strigolactones in promoting Arabidopsis seed germination.
