HORTICULTURE

Detailed explanation-1: -Most notably, cytokinin increases water loss by promoting shoot growth and limits water uptake by inhibiting root growth [25, 26]. In addition, cytokinin suppresses drought stress tolerance by repressing the expression of ABA-inducible genes [97].

Detailed explanation-2: -Cytokinins are a group of plant growth regulators which are primarily involved in performing cell division in plant roots, shoot system. This hormone helps in promoting the cell’s growth, development, differentiation, affecting apical dominance and delay in leaf senescence.

Detailed explanation-3: -Cytokinin regulates many important aspects of plant development in aerial and subterranean organs. The hormone is part of an intrinsic genetic network controlling organ development and growth in these two distinct environments that plants have to cope with.

Detailed explanation-4: -The plant hormones auxin and cytokinin are critical for plant regeneration in tissue culture, with cytokinin playing an instrumental role in shoot organogenesis. Type-B response regulators govern the transcriptional output in response to cytokinin and are required for plant regeneration.
