WebHere, we identify an F-box family E3 ubiquitin ligase named SHORT PRIMARY ROOT (SHPR) that regulates primary root (PR) meristem activity and cell proliferation in rice. SHPR loss-of-function mutations impair PR elongation in rice. SHPR is involved in the formation of a SCF complex with the Oryza sativa SKP1-like protein OSK1/20. WebGenetic experiments suggest that these three AIL genes do not act specifically in either the WUS/CLV or STM pathway regulating meristem function. Furthermore, these studies indicate that ANT , AIL6 and AIL7 have distinct functions within the meristem rather than acting in a strictly redundant manner. other apps like powerpoint https://euro6carparts.com
