Cytokinins inhibit morphogenesis in ptc
WebNov 1, 2016 · In Arabidopsis, cytokinins inhibit root growth through effects on cell proliferation and cell elongation. Here, we define key mechanistic elements in a regulatory network by which cytokinin inhibits root cell elongation in concert with the hormones auxin and ethylene. The auxin importer AUX1 functions as a positive regulator of cytokinin ...

Did you know?
Webcytokinins are an important regulatory factor of plant meristem activity and morphogenesis, with opposing roles in shoots and roots. Cytokinins were discovered during the 1950s because of their ability to induce plant cell division (1). Shortly after their discovery, Skoog and Miller coined the auxin–cytokinin hypoth-esis of plant ... WebAbstract.

Furthermore, this study was intended to establish how the different cytokinins affect the subsequent rooting of the regenerated shoots. Materials and Methods WebSep 9, 2024 · Cytokinins, a type of phytohormones that induce division of cytoplasm, have considerable value in agriculture due to their influences on several physiological processes of plants such as morphogenesis, development of chloroplast, seed dormancy, leaf senescence, etc. Previously, it was assumed that plants obtain cytokinin from the soil …
WebJan 9, 2024 · Cytokinins are inactivated by enzymes encoded by the CYTOKININ OXIDASE/DEHYDROGENASE ( CKX s) gene family that catalyzes the removal of the N 6 -isoprene side chain. CKX genes are expressed in different organs, at very low concentration, and with very specific patterns of expression. Within the cell, CKX proteins … WebMay 3, 2024 · Cytokinins like BA are glucosylated on the purine scaffold into biologically inactive storage forms either as the glucoside itself or by the β-glucosidase (McGaw et al. 1985).These storage forms accumulate in plants and later slowly release and cause rooting inhibition and abnormal growth patterns (Werbrouck et al. 1996).To overcome these …
