Plant Regeneration from in Vitro-selected Salt Tolerant Callus Cultures of Solanum Tuberosum L
This research work reports In vitro direct selection of salt-tolerant callus cultures and subsequent plant regeneration in two potato cultivars (Cardinal and Desiree). Results have shown more than 50% reduction in relative fresh callus mass in the two potato cultivars exposed to 120 mM NaCl. Callus morphology correspondingly changed from off-white to blackishbrown at 120 mM to acutely-necrotic ...
متن کاملHistology of somatic embryogenesis in rice (Oryza sativa cv. 5272)
Rice (Oryza sativa cv. 5272) embryogenic calli were obtained from mature zygotic embryos culture on Murashige & Skoog (1962) medium supplemented with 2.5 mg/l 2,4dichlorophenoxyacetic acid. Histological analysis of somatic embryogenesis revealed that after two weeks of culture of explants on the callus induction medium, somatic embryo development began with a cluster of proembryogenic cells in ...
متن کاملKikuyu Grass: A Valuable Salt-Tolerant Fodder Grass
The turf grass Pennisetum clandestinum Hochst. (kikuyu grass) is one of the candidate plants for utilization and reclamation of salinized areas. The capability of kikuyu grass to grow under saline conditions was tested during 6 months, under various irrigation treatments (tap water control, 80-mM, 150-mM, 200-mM, 240mM NaCl). Plant biomass production was visibly affected only at NaCl concentrat...
متن کاملIn vitro somatic embryogenesis from callus cultures of Cephaelis ipecacuanha
Callus was obtained from leaf explants of Cephaelis ipecacuanha on Murashige and Skoog (MS) basal medium supplemented with 0.5 mg/l Kin, 4.0 mg/l 2,4-D and 3% (w/v) sucrose [Murashige, T., Skoog, F., 1962. Plant Physiol. 15, 437±497]. Plantlet regeneration through somatic embryogenesis was achieved on MS medium containing 2.5 mg/l Kin, 1.0 mg/l 2,4-D and 3% (w/v) sucrose. Maturation and germina...
متن کاملCrossability barriers in the interspecific hybridization between Oryza sativa and O. meyeriana.
Oryza meyeriana Baill (GG genome) is a precious germplasm in the tertiary gene pool of cultivated rice (AA genome), and possesses important traits such as resistance and tolerance to biotic and abiotic stress. However, interspecific crossability barrier, a critical bottleneck restricting genes transfer from O. meyeriana to cultivars has led to no hybrids through conventional reproduction. There...
