With a very diverse structure and small molecules, phytohormones are regulators of plant growth development. Despite the fact that they synthesized by plants in quantities, highly active physiologically. According to their action, can be divided into two categories, as either activators development or inhibitors, with auxins cytokinins belonging former group. Auxins apical meristems shoots, but...

Leaves are specialized organs characterized by defined developmental destiny and determinate growth. The overexpression of Knotted1-like homeobox genes in different species has been shown to alter leaf shape and development, but a definite role for this class of genes remains to be established. Transgenics that overexpress Knotted1-like genes present some traits that are characteristic of alter...

Higher plant vasculature is characterized by two distinct developmental phases. Initially, a well-defined radial primary pattern is established. In eudicots, this is followed by secondary growth, which involves development of the cambium and is required for efficient water and nutrient transport and wood formation. Regulation of secondary growth involves several phytohormones, and cytokinins ha...

The establishment of the primary meristems through proliferation after germination is essential for plant post-embryonic development. Cytokinins have long been considered a key regulator of plant cell division. Here we show that cytokinins are essential for early seedling development of Arabidopsis. Loss of cytokinin perception leads to a complete failure of meristem establishment and growth ar...

Cytokinins are a major class of plant hormones that are involved in various aspects of plant development, ranging from organ formation and apical dominance to leaf senescence. Cytokinin and auxin have long been known to interact antagonistically, and more recent studies have shown that cytokinins also interact with other plant hormones to regulate plant development. A growing body of research h...

The present study was undertaken to investigate the possibility for developing Efficient Plant regeneration protocol in Vigno mungo L. For this, the effect of Cytokinens on in vitro regeneration from Cotyledonary explants was studied in Black gram (Vigno mungo L.) Hepper Var Vamban-1. The cytokinins used were 6-benzylaminopurine (BAP), Thidiazuron (TDZ), and kinetin (Kn). The regenerated shoots...

The contents of auxin (indole-3-acetic acid, IAA), cytokinins, and abscisic acid (ABA) were determined in explants (megagametophyte embryo), proliferating embryonal-suspensor mass (ESM), non-embryogenic callus Pinus sibirica Larix sibirica. Furthermore, the localization hormones cells was studied with immunohistochemical analysis. It shown that formation embryogenic cultures both species is ass...
