Cold tolerance in Osmotin transgenic tomato (Solanum lycopersicum L.) is associated with modulation in transcript abundance of stress responsive genes
Our containment trials have established cold tolerance in Nicotiana tabacum osmotin (Nt Osm) transgenic tomato (Solanum lycopersicum L. cv. Pusa Ruby). Though, the stress tolerance mechanisms have been studied at physio-biochemical levels, molecular mechanisms underlying the tolerant response are still not well studied. Therefore, quantitative transcript expression of Osmotin and other stress r...
متن کاملUp-regulation of plasma membrane H+-ATPase under salt stress may enable Aeluropus littoralis to cope with stress
Plasma membrane H+-ATPase is a major integral membrane protein with a role in various physiological processes including abiotic stress response. To study the effect of NaCl on the expression pattern of a gene encoding the plasma membrane H+-ATPase, an experiment was carried out in a completely random design with three replications. A pair of specific primers was designed based on the sequence o...
متن کاملInduced thiacloprid insensitivity in honeybees (Apis mellifera L.) is associated with up-regulation of detoxification genes.
Honey bees, Apis mellifera, are markedly less sensitive to neonicotinoid insecticides containing a cyanoimino pharmacophore than to those with a nitroimino group. Although previous work has suggested that this results from enhanced metabolism of the former by detoxification enzymes, the specific enzyme(s) involved remain to be characterized. In this work, a pretreatment of honey bees with a sub...
متن کاملBiotechnology of water and salinity stress tolerance.
Drought and salinity are among the environmental factors that constrain agricultural productivity most dramatically. Classical breeding programs aiming to improve stress tolerance have been hampered by the multigenic nature of the trait and the seemingly scarce natural genetic variability in crop plants. Novel genetic determinants governing the function of stomata and improving the performance ...
متن کاملAnxiety induced by prenatal stress is associated with suppression of hippocampal genes involved in synaptic function.
Exposure of pregnant women or animals to stress during a critical period of foetal brain development increases the likelihood of anxiety, depression and learning deficits that are associated with structural alterations in the offspring hippocampus. In this study, we report the effect of gestational stress in rats on anxiogenic behaviour and hippocampal gene expression of their 23-day-old female...
