Cytokinins inhibit morphogenesis in ptc
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 ... WebCytokinins are plant-specific chemical messengers (hormones) that play a central role in the regulation of the plant cell cycle and numerous developmental processes. Cytokinins were discovered by F Skoog, C Miller, and co-workers during the 1950s as factors that promote cell division (cytokinesis). The first cytokinin discovered was an adenine ...

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 … Webthe action of different cytokinins in varying concentrations with regard to the regeneration of shoots and roots from different expiants of lentil. Furthermore, this study was intended to establish how the different cytokinins affect the subsequent rooting of the regenerated shoots. Materials and Methods
WebPlant hormones are a group of unrelated chemical substances that affect plant morphogenesis. Five major plant hormones are traditionally described: auxins (particularly IAA), cytokinins, gibberellins, ethylene, and abscisic acid. In addition, other nutrients and environmental conditions can be characterized as growth factors. 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 …
