Superoxide dismutase: an all-purpose gene for agri-biotechnology

cyp11A1 Canola plants under short time heat stress conditions

“…Biotechnological methods are successfully used for understanding plant abiotic stress tolerance [1] and for applying for rapeseed creation with different stress resistance [2][3][4][5]. Transgenic canola plants overexpressing a vacuolar Na + /H + antiport from Arabidopsis thaliana were able to grow, to flower, and to produce seeds in the presence of 200 mM NaCl.…”

“…Seed yields and seed quality were not affected by the high salt concentration [2]. Overexpression of wheat mitochondrial Mn superoxide dismutase (Mn SOD3.1) enhanced transgenic canola heat, drought and cold tolerance both in the field and under artificial stress conditions [3]. Transgenic B. napus carrying bsubunit of Arabidopsis farnesyltransferase (ERA1) antisense construct driven by a drought-inducible rd29A promoter were more resistant to seed abortion induced by water deficit during flowering [4].…”

“…A number of changes mentioned for cyp11A1 canola plants are inherent in the plants with heterologous SOD expression, which are characterized by increasing adaptive properties when they were subjected to stresses of various origins [3,13]. And the aim of the present work was the investigation of cyp11A1 canola thermotolerance by using the short time heat stress.…”

“…And the aim of the present work was the investigation of cyp11A1 canola thermotolerance by using the short time heat stress. It was documented that results of the heat tolerance test (short-time growth under 42 º Ñ in growth chamber) positively correlated with improvement of high temperature resistance in field trial [3]. We analyzed such physiological and biochemical parameters which are usually used to characterize the properties of plants under stress as relative water content [14,15], electrolyte leakage [15,16], photosynthetic pigment content and ratios [15,[17][18][19], SOD activity [3,20,21].…”

“…Temperature was increased with 2 ºÑ/h gradient to 42 ºÑ. Plants were than taken isothermal at 42 ºÑ for 16 h [3].…”
