Soil salinity is a major environmental stress limiting plant productivity. Vacuole Na+/H+ antiporters play important roles for the survival of plants under salt stress conditions. We have developed salt stress tolerant transgenic tomato plants (Solanum lycopersicum cv. PED) by overexpression of the wheat Na+/H+ antiporter gene TaNHX2 using Agrobacterium(More)
Transgenic chilli pepper (Capsicum annuum L.) plants tolerant to salinity stress were produced by introducing the wheat Na+/H+ antiporter gene (TaNHX2) via Agrobacterium-mediated transformation. Cotyledonary explants were infected with Agrobacterium tumefaciens strain LBA4404 harboring a binary vector pBin438 that contains a wheat antiporter (TaNHX2) gene(More)
The objective of the present study was to develop a protocol for in vitro plantlet regeneration and Agrobacterium tumefaciens-mediated genetic transformation using immature cotyledon explants of Indian Kino tree (Pterocarpus marsupium Roxb.). Immature cotyledon explants excised from 9-day-old axenic seedlings produced optimal callus on Murashige and Skoog(More)
A simple and highly efficient protocol has been developed for in vitro regeneration of Pterocarpus marsupium using immature zygotic embryo (IZE) as explant. The highest frequency of shoot regeneration (93.8%) was obtained on Murashige and Skoog (MS) medium supplemented with 3.0 mg·L−1 6-benzylaminopurine (BA) and 0.5 mg·L−1 indole-3-acetic acid (IAA),(More)
Fourteen new 4-alkyl/aryl-3,5-bis-(carboethoxy/carbomethoxy)-1,4-dihydro-2,6-dimethylpyridines (4a–4n) have been prepared by conventional and microwave irradiation (MWI) methods from a three component reaction mixture viz., alkyl acetoacetate (1), appropriate aldehyde (2) and ammonium acetate (3). The compounds prepared have been purified and characterized(More)
