Web30 mrt. 2024 · An intercalary meristem is a type of primary meristematic tissue that aids in vertical growth by increasing the length of a plant or tree. Small, totipotent, thin-walled, and protoplasm-filled cells make up this meristematic area. The following are the distinguishing characteristics of the intercalary meristem: 1. Divergence in nature. WebA schematic model of the WUSCHEL (WUS) transcription factor gene showing the regulation of diverse functions in plant growth and development.As shown in Fig. 1, the stem cells are maintained in the apical shoot meristem by a regulatory feedback loop between the stem cells and organizing center (OC), via CLV3 and WUS expression. The …

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
