Abstract:
... KEY MESSAGE: Late-embryogenesis-abundant proteins (LEA) typically accumulate to high levels during seed dehydration and have an important role in the plant response to abiotic stresses. Transgenic hybrid poplars of 9-year-old TaLEA lines showed adaptation to drought and saline–alkali conditions. The exogenous gene was expressed normally, and the T-DNA insertion sites were identified on different c ...

Abstract:
... Membrane lipids change drastically in plants when they suffered from hypoxia (oxygen deficiency) stress. Overall, hypoxia stress lowers the contents of total lipids, inhabits lipid biosynthesis, and stimulates lipid degradation, leading to the accumulation of free fatty acids. Lipid alterations include changes in the contents of lipid classes, the extent of saturation, and the length of acyl chain ...
