Direct Regeneration of Chickpea (Cicer arietinum L.) from Adventitious Buds
The seeds of ten different genotypes of chickpea (Cicer arietinum L.) originated from Egypt, ICARDA and Saudi Arabia, were used to screen their tissue culture response on various media combination. MS media supplemented with 1, 2 and 4 mg of each of IBA and transzeatin /l, were tested. The results showed that stem results were far better from leaves explants. The callus induction ranged from 6....
متن کاملOptimalisation of expression conditions for production of round-leaf sundew chitinase (Drosera rotundifolia L.) in three E. coli expression strains Optimalizácia podmienok expresie droserovej chitinázy (Drosera rotundifolia L.) v troch expresných kmeňoch E. coli
Round-leaf sundew (Drosera rotundifolia L.), family Droseraceae, genus Drosera, is one of a few plant species with a strong antifungal potential. Chitinases of carnivorous plants play an important role in decomposition of chitin-containing cell structures of insect prey. The cell wall of many phytopathogenic fungi also contains chitin, which can be utilized by chitinases, thus round-leaf sundew...
متن کاملAn Improved 2-step Liquid Culture System for Efficient In Vitro Shoot Proliferation of Sundew (Drosera rotundifolia L.)
An efficient procedure for in vitro shoot production of the medicinal plant sundew (Drosera rotundifolia L.) was developed. Of three cytokinins tested, zeatin (ZEA) at a concentration of 2 μM resulted in the formation of large numbers of adventitious shoots on leaf explants. A larger size of the small shoots was achieved by combining a 2-weeks preculture with ZEA (step 1: shoot induction) with ...
متن کاملRed trap colour of the carnivorous plant Drosera rotundifolia does not serve a prey attraction or camouflage function.
The traps of many carnivorous plants are red in colour. This has been widely hypothesized to serve a prey attraction function; colour has also been hypothesized to function as camouflage, preventing prey avoidance. We tested these two hypotheses in situ for the carnivorous plant Drosera rotundifolia. We conducted three separate studies: (i) prey attraction to artificial traps to isolate the inf...
متن کاملMolecular analysis of signals controlling dormancy and growth in underground adventitious buds of leafy spurge.
Dormancy and subsequent regrowth of adventitious buds is a critical physiological process for many perennial plants. We have used the expression of hormone and cell cycle-responsive genes as markers to follow this process in leafy spurge (Euphorbia esula). In conjunction with earlier studies, we show that loss of mature leaves results in decreased sugar levels and increased gibberellin percepti...
