WebSTM promotes cell division and inhibits cell differentiation in the SAM . WUS, a homeodomain transcription factor, is essential for reprogramming during de novo shoot regeneration . One study showed that a wus mutant failed to regenerate the shoots, whereas the overexpression of WUS led to shoot regeneration on a hormone-free medium . WebOct 10, 2013 · Background. In the root apical meristem, which contains the stem cells that feed into root development, the phytohormones auxin and cytokinin play opposing roles, with auxin promoting cell division and cytokinin promoting cell differentiation. Cytokinin acts in the root tip in part by modulating auxin transport through regulation of the level ...

WebThis antagonistic auxin-cytokinin network provides the molecular basis for the opposite effects observed in root meristem size (enlarged and reduced, respectively) resulting from exogenous cytokinin or auxin treatment (37, 38). In summary, auxin promotes cell division, whereas cytokinin promotes differentiation. WebAug 22, 2008 · Cytokinin acts as a positive regulator of cell division in the shoot (Werner et al., 2003; Higuchi et al., 2004; Nishimura et al., 2004; Riefler et al., 2006). Consistent with the type-B ARRs mediating the positive effect of cytokinin in shoots, we found that the leaves of the arr1-3 arr10-5 arr12-1 triple mutant had approximately half the number of … kusto top command
