Overexpression of osmotin gene confers tolerance to salt and drought stresses in transgenic tomato (Solanum lycopersicum L.)

Abstract: Abiotic stresses, especially salinity and drought, are major limiting factors for plant growth and crop productivity. In an attempt to develop salt and drought tolerant tomato, a DNA cassette containing tobacco osmotin gene driven by a cauliflower mosaic virus 35S promoter was transferred to tomato (Solanum lycopersicum) via Agrobacterium-mediated transformation. Putative T0 transgenic plants were screened by PCR analysis. The selected transformants were evaluated for salt and drought stress tolerance by physi… Show more

“…Components of the second group have functions in membrane protection, including production of osmoprotectants and antioxidants as well as reactive oxygen species scavengers. All of these processes have been major targets of genetic engineering approaches to produce plants that have enhanced stress tolerance (Valliyodan and Nguyen, 2006;Trujillo et al, 2008;Goel et al, 2010;Quan et al, 2010;Manavalan et al, 2012).…”

“…The expression pattern of these stress related genes were similar to the drought tolerant plants as reported earlier. [21][22][23][24] Among the up-accumulated proteins in response to drought stress in NtGp11 spot no. 4 and 13 had identified to HSP70 like proteins and spot no.…”

“…against a concentration gradient) across plant cell membranes (plasmalemma and tonoplast) is usually coupled to the proton (H + ) electrochemical potential established by H + -translocating pumps. The vacuolar Na + /H + antiporter and H + -pyrophosphatase pump (H + -PPase) are genotype dependent and confer tolerance to salinity (Goel et al, 2010;Bhaskaran et al, 2011). Additionally, resistant crops benefit from the higher capacity of K + -Na + homeostasis.…”
