Leaf initiation was previously thought to be self-regulated and not reliant on environmental cues. However, a recent study has revealed that light redirects meristem fate from maintenance to lateral organ initiation, through the regulation of the plant hormones auxin and cytokinin.

The plant hormone auxin has been implicated in vascular development, but the molecular details of patterned vascular differentiation have remained elusive. Research in the past year has identified new genes that control vascular patterning, and auxin transport and perception. New experimental strategies have been employed to study vascular development. Together, these findings have generated a ...

Dog rose (Rosa canina) has been using as a rootstock for ornamental roses also it is one of the medicinal plants. It can be propagated under in vitro conditions. After removing chilling requirement of buds, axillary wood buds of dog rose were cut in three nodal positions (lower, middle and terminal) on the stem and then explants after decontamination, cultured on Murashige and Skoog medium (MS ...
