Splet01. feb. 2001 · Cytokinins modulate a number of important developmental processes, including the last phase of leaf development, known as senescence, which is associated … SpletCytokinin is generally considered to promote mitotic cell division in the shoot, but differentiation and transition to the endocycle in the root. Here we consider recent data on the inputs by which cytokinins positively and negatively regulate transitions through the cell cycle. Cytokinin positively regulates cell division and also serves a key ...

SpletThe effect is in two ways: first, it prevents the formation of hydrolases, e.g., nucleases, proteases and second, it causes immobilisation of nutrients or their transport to cytokinin treated areas. Studies by Mothes and Engelbrecht have shown younger leaves of tobacco had more of cytokinins and tended to lose less of applied14C amino acid as ... Splet20. jan. 2015 · The net effect of the distribution of these IAA influx and efflux carriers, coupled with localized biosynthesis, is to generate auxin asymmetries that regulate cell differentiation and division during plant growth and development. ... fall into two main classes called type-A and type-B RRs.
