WebOct 19, 2024 · CLV3-mediated signaling through these receptor complexes limits stem cell accumulation by restricting the WUS expression domain to the OC [48,49]. Thus, the CLV-WUS pathway functions as a dynamic … WebNov 15, 2010 · This CLV3-WUS negative feedback loop is represented by the opposite phenotype of these loss-of-function mutants: wus mutants exhibit SAM termination, whereas clv3 mutants produce an enlarged SAM (Clark et al., 1995; Laux et al., 1996). This model is also supported by the fact that CLV3 overexpression leads to wus-like phenotype (Brand …

WebFeb 27, 2024 · WUS is a homeodomain transcription factor expressed in the organizing centre that moves to the central zone to promote stem cell fate. CLV3 is a peptide whose expression is induced by WUS in the central zone and that can move back to the organizing centre to inhibit WUS expression. WebDec 17, 2024 · The maintenance of the stem cell niche in the shoot apical meristem, the structure that generates all of the aerial organs of the plant, relies on a canonical feedback loop between WUSCHEL (WUS) and CLV3 (CLV3). WUS is a homeodomain transcription factor expressed in the organizing center that moves to the central zone to promote stem …
WebApr 16, 2024 · However, CLV3 signaling partially offsets this instability in the L1 and the L2 layers. A relatively higher WUS (2X) represses CLV3 which destabilizes WUS (0.5X), which in turn activates CLV3, thus forming a … http://www.ebiotrade.com/newsf/2024-9/20240902084704711.htm
WebAug 16, 2024 · CLV3-WUS signaling is involved in this process by regulating the maintenance of the stem cell niche in the AZ. It is worth noting that three weak Slclv3 alleles showed mild fasciation phenotypes but considerable abscission defects. We cannot rule out the possibility that these three independent mutants still have a weak CLV3 signal, since … WebWUS promotes the expression of CLV3, which, via activation of the signaling pathway dependent by the CLV1/CLV2 protein complex, acts on WUS transcription and limits the size of the...
