A procedure was developed for in vitro propagation of Curculigo latifolia through shoot tip culture. Direct regeneration and indirect scalp induction of Curculigo latifolia were obtained from shoot tip grown on MS medium supplemented with different concentrations and combinations of thidiazuron and indole-3-butyric acid. Maximum response for direct regeneration in terms of percentage of explant...

Plant cells are totipotent and competent to regenerate from differentiated organs. It has been shown that two phytohormones, auxin and cytokinin, play critical roles within this process. As in animals, the regenerative capacity declines with age in plants, but the molecular basis for this phenomenon remains elusive. Here, we demonstrate that an age-regulated microRNA, miR156, regulates shoot re...

We recently demonstrated the circadian clock modulated water dynamics in the roots of a small model plant, Arabidopsis thaliana, by the Nuclear Magnetic Resonance (NMR) microimaging technique. Our developed technique was able to visualize the water distribution that depended on differences in the (1)H signal among region in the shoot, such as the shoot apex, the hypocotyl and the root shoot jun...

BACKGROUNDS AND AIMS Shoot demography affects the growth of the tree crown and the number of leaves on a tree. Masting may cause inter-annual and spatial variation in shoot demography of mature trees, which may in turn affect the resource budget of the tree. The aim of this study was to evaluate the effect of masting on the temporal and spatial variations in shoot demography of mature Betula gr...

Micropropagation of Asclepias curassavica L. a medicinal plant valued for its medicinal properties has been carried out using two different plant culture media, Murashige and Skoog (MS) and L2. L2 medium proved to be superior to MS medium in terms of shoot multiplication and shoot length. Nodal explants showed enhanced organogenic response than shoot tip explants. Basal nodal explants produced ...

This study investigates the functional significance of heterophylly in Ginkgo biloba, where leaves borne on short shoots are ontogenetically distinct from those on long shoots. Short shoots are compact, with minimal internodal elongation; their leaves are supplied with water through mature branches. Long shoots extend the canopy and have significant internodal elongation; their expanding leaves...

Cotton (Gossypium spp.) belonging to the genus Gossypium in the family Malvaceae. Cotton is an important fibre crop of global importance. It is grown in tropical and subtropical regions of more than 80 countries with an annual production of 20 million tonnes. It is an important source of oil and high quality protein meal and plays a significant role in the national economy. Among the cotton pro...

Shoots can be regenerated from Arabidopsis (Arabidopsis thaliana) root explants in tissue culture through a two-step process requiring preincubation on an auxin-rich callus induction medium. Regenerating tissues can be directed along different developmental pathways leading to the formation of shoots, new roots, or callus by transferring to the appropriate organ induction medium. Using gene-pro...
