optimization of regeneration methods in cotton is necessary to improve and successful production of transgenic cotton cultivars by tissue culture technique. this study was conducted to determine the genotypic effect on callus induction in cotton using 3 genotypes (coker349, 4-s-4 and c1211) and coker 312 selected and a study was carried out in cotton research institute of gorgan using a factori...

Polyamines are considered to participate in various processes of plant development. In this study, the possible implication of putrescine catabolism by the copper-containing amine oxidases (CuAOs, EC 1.4.3.6) in the development of roots and hypocotyls was examined. For this purpose, two cDNA clones of Glycine max (L.) Merr. cv. Williams, designated as GmCuAO1 and GmCuAO2, exhibiting extensive s...

Representative species of the Taxus genus, known since antiquity for their toxicity, have been an essential plant resource production extracts with medicinal properties (anti-inflammatory, antifungal, and antibacterial) and, more recently, study allelopathic significant implications in organic agriculture (bioherbicidal potential). With a view to development this new direction research, present...

Three growth inhibitors which might be involved in phototropism of Sakurajima radish (Raphanus sativus var. hortensis f. gigantissimus Makino) hypocotyls, were isolated as crystalline forms from light-exposed radish seedlings and identified as cis- and trans-raphanusanins and 6-methoxy-2,3,4,5-tetrahydro-1,3-oxazepin-2-one (designated raphanusamide). The cis- and trans-raphanusanins inhibited g...

The process of etiolation contributes significantly to vegetative propagation and root formation woody plants. However, the molecular interaction pattern different factors for etiolated adventitious development in plants remains unclear. In present study, we explored changes at stages Robinia pseudoacacia. Histological transcriptomic analyses were performed lower portion hypocotyls ascertain re...

The investigation was conducted on wet and dry seasons of Ethiopia during the year 2012/2013 at Wondo Genet Agricultural Research Center Nursery site. Four levels of cutting size and three levels of cutting positions were arranged in randomized complete block design with three replications. Data on seedling height, branch number/seedling, root number/seedling, root weigh/seedling, root length/s...

A protocol for direct organogenesis in Bixa orellana (pink flowers variety) has been developed with significant organogenic response from rooted hypocotyls, hypocotyl segments, and cotyledonary leaf explants on Murashige and Skoog (MS) medium supplemented with 2.0 mg L thidiazuron and 0.25% coconut water or 7.0 mg L N-Benzyladenine and 0.1 mg L a-naphthalene acetic acid. Thidiazuron in combinat...
