optimization of callus induction and micropropagation of four varieties of grape (vitis vinifera l.)
background and objectives: grape has high nutritional value and it is an economically important horticultural plant in the world. iran has seventh producer grape rank in the world. today tissue culture is one of technique which can be used in grape propagation and breeding. material and method: in order to optimization of callus induction and micropropagation of grape in vitro condition, this i...
Carbon and nitrogen are the two elements that most affect plant organogenesis. In vitro, usually as part of the macronutrients. Some anecdotal evidence from the literature suggests that the ammonium (NH4+) to nitrate (NO3–) ratio may affect orchid organogenesis. In this study, to test this hypothesis, different NH4+: NO3– ratios were tested on the development of protocorm-like bodies (PLBs) of ...
Cytokinins are plant hormones implicated in diverse and essential processes in plant growth and development, and key genes for the metabolism and actions of cytokinins have recently been identified. Cytokinins are perceived by three histidine kinases--CRE1/WOL/AHK4, AHK2, and AHK3--which initiate intracellular phosphotransfer. The final destination of the transferred phosphoryl groups is respon...
In order to improve the quantity and quality of raisins made from Sultani seedless grapes using plant growth regulators, an experiment was conducted in a randomized complete block design in a commercial vineyard near Bonab city (West Azarbaijan Province, Iran). For this purpose, spraying was carried out at fruit set stage using a combination of CPPU and GA3. Then the produced fruits were turned...
The changes in the contents of free and bound gibberellin-like activity (GA) of Tulipa gesneriana L. cv. Ralph during development under 2 temperature conditions were studied. The results show that the content of free GA of bulbs grown at 18 degrees increased by 67% over the initial level during development. The bound GA showed a slight initial increase and was followed by a rapid decrease. In c...
RghBNG, a gene of unknown function, was cloned from Rehmannia glutinosa by reverse transcription PCR and rapid amplification of cDNA ends. The full-length cDNA of RghBNG was 548 bp with a282-bp open reading frame. It encoded a polypeptide of 93 amino acids with a predicted molecular weight of 10.5 kDa and a theoretical isoelectric point of 9.25. Bioinformatics analysis indicated that RghBNG had...
