The initial step of cytokinin biosynthesis in higher plants is the formation of cytokinin nucleotides, namely, isopentenyladenosine 5′-tri-, di-, or monophosphate (iPRTP, iPRDP, or iPRMP, respectively), from ATP, ADP, or AMP and dimethylallyl pyropho- sphate (DMAPP) by IPTs5. LOGs, ...

Strong arguments suggest that land colonization by plants, initiated more than 400 million years ago, was successful thanks to close interactions with fungi [10]. In addition, a role of CKs in interactions in several plant–fungi systems has been described. In this context, it is noteworthy tha...

What is the role of auxins in plants?Plant HormonesPlant hormones are organic, signaling compounds that are synthesized by different plant organs which stimulate the growth and development of another plant organ. The common plant hormones include auxin, cytokinin, ethylene, gibberellins, and abscisic ...
The mechanisms by which plants modulate their growth rate in response to environmental and developmental conditions are unknown, but are presumed to involve specialized regions called meristems where cell division is concentrated1,2,3,4,5. The possible role of cell division in influencing meristem ac...
In plants, callus formation is a key step in the cell reprogramming pathway for somatic embryogenesis and is triggered and influenced by many factors, including wounding and hormonal (auxin, cytokinin, abscisic acid, and ethylene) status of the tissue. The remarkable totipotency of plant somatic ...
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...
Senescence is a degenerative process triggered by intricate and coordinated regulatory networks, and the mechanisms of age-dependent senescence and stress-induced premature senescence still remain largely elusive. Thus we selected leaf samples of develop
