WebCytokinins impact numerous aspects of plant growth and development. This study reports that constitutive ectopic overexpression of a rice cytokinin-activation enzyme-like gene, OsLOGL5, significantly reduced primary root growth, tiller number, and yield. Conversely, mutations at the 3'-end of OsLOGL5 CDS resulted in normal rice plant morphology ... WebOct 4, 2024 · Nitrogen-dependent IPT expression accumulates iP- and tZ-type cytokinin species in the roots and shoots (Takei et al., 2004a, b) and activates cytokinin signaling (Taniguchi et al., 1998).
