OsNCED5 confers cold stress tolerance through regulating ROS homeostasis in rice.

Cold stress is one of the most serious abiotic stresses that affects the growth and yield in rice. However, the molecular mechanism by which abscisic acid (ABA) regulates plant cold stress tolerance is not yet clear. In this study, we identified a member of the OsNCED (9-cis-epoxycarotenoid dioxygenase) gene family, OsNCED5, which confers cold stress tolerance in rice.

An ABA biosynthesis enzyme gene OsNCED4 regulates NaCl and cold stress tolerance in rice.

Rice (Oryza sativa L.) is susceptible to various abiotic stresses, such as salt, cold, and drought. Therefore, there is an urgent need to explore the relevant genes that enhance tolerance to these stresses.

Physiological and transcriptomic analysis uncovers salinity stress mechanisms in a facultative crassulacean acid metabolism plant .

is a precious medicinal Chinese herb that employs facultative crassulacean acid metabolism (CAM) and has a high degree of abiotic stress tolerance, but the molecular mechanism underlying the response of this orchid to abiotic stresses is poorly understood. In this study, we analyzed the root microstructure of . plantlets and verified the presence of chloroplasts by transmission electron microscopy.

Structural Analysis and Quantitative Determination of Clevidipine Butyrate Impurities Using an Advanced RP-HPLC Method.

Eleven potential impurities, including process-related compounds and degradation products, have been analyzed by comprehensive studies on the manufacturing process of clevidipine butyrate. Possible formation mechanisms could also be devised. MS and NMR techniques have been used for the structural characterization of three previously unreported impurities (Imp-3, Imp-5 and Imp-11).
