Utilization of genes encoding osmoprotectants in transgenic plants for enhanced abiotic stress tolerance Electron. J. Biotechnol.
Khan,Mohammad Sayyar; Ahmad,Dawood; Khan,Muhammad Adil.
Global agriculture in the context of growing and expanding populations is under huge pressure to provide increased food, feed, and fiber. The recent phenomenon of climate change has further added fuel to the fire. It has been practically established now that the global temperature has been on the increase with associated fluctuations in annual rainfall regimes, and the resultant drought and flood events and increasing soil and water salinization. These challenges would be met with the introduction and utilization of new technologies coupled with conventional approaches. In recent years, transgenic technology has been proved very effective in terms of production of improved varieties of crop plants, resistant to biotic stresses. The abiotic stresses such as...

Characterization of the genetic structure of mango ginger (Curcuma amada Roxb.) from Myanmar in farm and genebank collection by the neutral and functional genomic markers Electron. J. Biotechnol.
Jatoi,Shakeel Ahmad; Kikuchi,Akira; Ahmad,Dawood; Watanabe,Kazuo N.
A preliminary characterization was undertaken to describe genetic structure of mango ginger (Curcuma amada) acquired from farmers and ex situ genebank in Myanmar using neutral (rice SSR based RAPDs) and functional genomic (P450 based analog) markers. The high polymorphism (> 91%) depicted has displayed existence of genetic variability in the germplasm investigated. Large number of source-specific alleles (neutral-markers = 78, functional-markers = 63) was amplified which revealed that neutral regions of the mango ginger were more variable compared with the functional regions. The major fraction of the molecular variance (neutral-markers = 85%, functional-markers = 93%) was explained within germplasm acquisition sources and this tendency was also...
