WebWe demonstrate that the barley SEPALLATA MADS-box protein HvMADS1 is responsible for maintaining an unbranched spike architecture at high temperatures, while the loss-of-function mutant forms a branched inflorescence-like structure. HvMADS1 exhibits increased binding to target promoters via A-tract CArG-box motifs, which change conformation ... WebDec 24, 2024 · Development of the grain-bearing organ, or spike (inflorescence) is critical to cereal grain development and yield. Shaw et al. found that FT2, the closet paralogue of florigen candidate FT1 in wheat, had a minor effect on heading date in wheat but a significant contribution to spike development, including regulation of the number of …
