Cytokinin signaling during root development

WebPrevious studies had shown that cytokinin and auxin interact during meristem development and function. In contrast to these studies, we found that auxin and cytokinin also interact beyond meristems in shoot and root organs and that this interaction determines the size of shoots and roots. ... Cytokinin signaling was increased in auxin resistant ... WebIn M. truncatula, activation of genes related to cytokinin biosynthesis/signaling during nodule development begins concurrently with the initiation of cell division in pericycle and cortex (10–12 HPI), while activation of these cytokinin signaling genes was not observed during LR initiation (Schiessl et al. 2024).

WebCytokinin plays a crucial role in regulating the proliferation and differentiation of plant cells. Considerable efforts in the last few years have been directed toward the discovery of proteins and enzymes that function in cytokinin signaling and metabolism (Ferreira and Kieber 2005; Sakakibara 2006). WebHere, we identified a rice AP2/ERF protein, ERF3, which interacts with WOX11 and was expressed in crown root initials and during crown root growth. Functional analysis revealed that ERF3 was essential for crown root development and acts in auxin- and cytokinin-responsive gene expression.
