Genetic manipulation of plants for increased drought tolerance
On a world basis, water availability is considered the main constraint for crop production. Concerns about water accessibility have always accompanied crop production in dry areas, which are on the other hand the most extensive areas for agriculture on the earth. As a consequence, men had to develop agricultural strategies to cope with water shortage, growing the plants during the short climati...
متن کاملPhenotypic approaches to drought in cassava: review
Cassava is an important crop in Africa, Asia, Latin America, and the Caribbean. Cassava can be produced adequately in drought conditions making it the ideal food security crop in marginal environments. Although cassava can tolerate drought stress, it can be genetically improved to enhance productivity in such environments. Drought adaptation studies in over three decades in cassava have identif...
متن کاملPhysiological and molecular characterization of drought responses and identification of candidate tolerance genes in cassava
Cassava is an important root crop to resource-poor farmers in marginal areas, where its production faces drought stress constraints. Given the difficulties associated with cassava breeding, a molecular understanding of drought tolerance in cassava will help in the identification of markers for use in marker-assisted selection and genes for transgenic improvement of drought tolerance. This study...
متن کاملGenetic and genomic tools to improve drought tolerance in wheat.
Tolerance to drought is a quantitative trait, with a complex phenotype, often confounded by plant phenology. Breeding for drought tolerance is further complicated since several types of abiotic stress, such as high temperatures, high irradiance, and nutrient toxicities or deficiencies can challenge crop plants simultaneously. Although marker-assisted selection is now widely deployed in wheat, i...
متن کاملStudy of Genetic Variation and Drought Tolerance in Commercial Rapeseed (Brassica napus L.) Cultivars
In order to identify drought stress tolerance in rapeseed, nine commercial rapeseed cultivars (Opera, Karaj1, Karaj2, Karaj3, Zarfam, Okapi, Talayeh, Licord and Modena) were evaluated under two conditions (normal and drought stress) in Kangavar region in the west Iran in 2014-2015 growing season. This research was carried out in a split plot experiment based on completely randomized design in f...
