Floral induction is a crucial developmental step in higher plants. Florigen, a mobile floral activator that is synthesized in the leaf and transported to the shoot apex, was recently identified as a protein encoded by FLOWERING LOCUS T (FT) and its orthologs; the rice florigen is Heading date 3a (Hd3a) protein. The 14-3-3 proteins mediate the interaction of Hd3a with the transcription factor Os...

An efficient in-vitro micropropagation protocol has been developed for Berberis chitria (Lindl.) - a rare medicinal plant from Himachal Pradesh, India using seeds and nodal explants. The effects of different concentrations BAP GA3 seed germination was investigated consequently 6.0 mg/l + 0.0 reported to be excellent germination. Callus induction leaf explants aseptically grown seedling were als...

tissue culture is an attractive alternative for plant propagation. micropropagation is a technique to ensure a constant and uniform source of ornamental plants. matthiola incana is an important ornamental species mainly cultivate by seed. matthiola incana seeds were germinated on solid ms medium without plant growth regulators. shoot proliferation and root formation are possible using kinetin (...

The uptake and metabolism of the cytokinin benzyl adenine (BA) was compared in two lines of Petunia hybrida Vilm. differing in their shoot organogenic response. Leaf transfer experiments using shoot induction medium containing 4.4 micromolar BA showed that leaf explants from petunia line St40 required a shoot induction period of 6 to 10 days for commitment to shoot organogenesis; whereas leaf e...

Short- and long-distance circadian communication is essential for integration of temporal information. However, a major challenge in plant biology is to decipher how individual clocks are interconnected to sustain rhythms in the whole plant. Here we show that the shoot apex is composed of an ensemble of coupled clocks that influence rhythms in roots. Live-imaging of single cells, desynchronizat...

The Malnad region located in the Western Ghats of Karnataka is known for the cultivation of indigenous rain fed land race cultivar of rice. The present study was to investigate the callogenic and caulogenic potentialities of the two indigenous rice cultivar namely Karimundaga and Kanadatumba using dehusked mature embryo explants. For callus and shoot bud differentiation, the explants were cultu...

the present work developed an efficient plant regeneration and propagation system via direct organogenesis for morinda officinalis how., a valuable endangered medicinal plant. the effects of explant types on shoot induction, plant growth regulators on shoot proliferationand elongation and the subsequent rooting ability of shoots were examined. among the various types of explant, direct shoot pr...
