Genomics approaches to investigate drought tolerance in
Wheat in a Hot and Dry Climate вЂ“ Program 1 Drought and. From the publicly available genomics information and also through literature survey, three putative candidate genes namely, Osmotin, DREB2 and DREB1A (CBF3) were selected for analysing their role in drought tolerance in rice. Gene specific primers were designed for isolating Osmotin and DREB2 from a set of two contrasting genotypes namely Apo (drought tolerant cultivar) and IR64 (drought, genomics protocols used to identify drought resistance. Insufﬁcient phenotyping of experimental transgenic plants for Insufﬁcient phenotyping of experimental transgenic plants for drought resistance often does not allow true conclusions about the real function of the discovered genes towards drought.

Genomics of Drought SpringerLink. drought tolerance have been used. RAPD PCR using P6 marker revealed characteristic loci at 920 bp region in 75% of RAPD PCR using P6 marker revealed characteristic loci at 920 bp region in 75% of genotype electrophoretic profiles., International research has found how plants, such as rice and wheat, sense and respond to extreme drought stress, in a breakthrough that could lead to the development of next-generation drought.

Genomics of Drought SpringerLink. Novel traits and alleles for drought and heat tolerance During reproductive development both heat and drought stresses reduce grain number and grain weight. This could be due to various processes, e.g., failed seed set could be due to pollen sterility, failed pollination or accelerated senescence. Drought tolerance is a difficult trait to define as it encompasses a wide range of char- acteristics involving multiple genetic, physiological, cellular and biochemical strategies in the plant..
Breeding of superior drought tolerant wheat varieties can be harnessed through molecular markers, genomics and post genomic strategies (Nguyen et al., 2004). We investigated the possibility of modulating the transcriptional regulation of drought and cold responses in the agriculturally important species, wheat and barley, with a view to increase drought and frost tolerance.
