Cryptic bract
WebJul 1, 2024 · The cells within this bump express a lateral organ marker, orthologous to FILAMENTOUS FLOWER/YABBY3 indicating that a “cryptic bract” is present and its outgrowth is somehow suppressed [88], [80]. Bract suppression is clearly under genetic regulation as multiple mutants in the grasses have de-repressed bracts. http://www.lsbg.cn/yanjiuyuan/32.html
