Structural Requirements of Strigolactones for Shoot Branching Inhibition in Rice and Arabidopsis.
Sakai, Japan. In Plant Cell Physiol, Jun 2015
Moreover, yeast two-hybrid experiments using a possible SL receptor, DWARF14 (D14), and a repressor in the SL signaling pathway, DWARF53 (D53), showed that D14 can interact with D53 in the presence of (2'R) stereoisomers of SLs, but not (2'S) stereoisomers, suggesting that the stereostructure of SLs is crucial for the interaction of these proteins.
Signalling and responses to strigolactones and karrikins.
Australia. In Curr Opin Plant Biol, 2014
D3 mediates SL-dependent ubiquitination and proteolysis of DWARF53 (D53) protein, thought to be involved in the control of gene expression, while a related protein SUPPRESSOR OF MAX2-1 (SMAX1) is implicated in the response to KAR in Arabidopsis.
DWARF 53 acts as a repressor of strigolactone signalling in rice.
Beijing, China. In Nature, 2014
Here we report the characterization of a dominant SL-insensitive rice (Oryza sativa) mutant dwarf 53 (d53) and the cloning of D53, which encodes a substrate of the SCF(D3) ubiquitination complex and functions as a repressor of SL signalling.
