in plants iszeatin, but many other natural cytokinins have been isolated, includingdihydrozeatin, isopentenyladenine, or benzyladenine. Cytokinins are present in most plant tissues. They are mainly biosynthesized in situ. The main step of the cytokinin-biosynthesis pathway is the transfer of the ...
phosphoribohydrolase activity as Cg1261 (Fig. 5b), indicating that the DNR region is not involved in the enzyme reaction, as we previously suggested based on the structural observations. In cytokinin biosynthesis, the most important enzyme is isopentenyltransferase (IPT), which transfers the ...
Auxin and cytokinin are two important hormones that play a key role in plant growth and development [1, 2, 3]. Despite their importance, key genes controlling the biosynthesis of the two hormones have only been identified recently. Indole-3-acetic acid (IAA), the main auxin in plants, can...
enhancement under elevated CO2, demonstrating the involvement ofde novocytokinin biosynthesis for a robust growth response. We propose that plants employ a system to regulate growth in response to elevated CO2in which photosynthetically generated sugars inducede novocytokinin biosynthesis for growth ...
namelygibberellic acid,abscisic acid,ethylene,auxins, andcytokinins. The scope of this article is limited to cytokinins which serve some very amazing and indispensable roles in plants. Read on to learn more about what is cytokinin hormone in plants, its types, functions,biosynthesis, examples, and...

8.Furthermore, effects of auxin treatment of decapitated plants on the expression of cytokinin biosynthetic genes suggest that D10 promotes cytokinin biosynthesis by reducing auxin levels. 此外,生长素处理去顶植株影响了细胞分裂素合成基因的表达,表明D10通过降低生长素的水平促进细胞分裂素的合成。
Studies of cytokinin biosynthesis and its actions in the past 20 years have revealed a basic frame of cytokinin biosynthesis in plants and some phytopathogens, as well as the biological significance of its structural variations. These findings have provided valuable information for understanding the ...
The initial products of de novo cytokinin biosynthesis in higher plants and Agrobacterium are different, and the regulatory systems in biosynthesis and homeostasis are finely controlled and appear to be important in communicating nutrient signals to morphogenetic responses. The cytokinin receptors have ...
