In angiosperms, NADPH: protochlorophyllide oxidoreductase (POR) catalyzes the photoreduction of protochlorophyllide (Pchlide) to chlorophyllide (Chlide), the only light-dependent step in chlorophyll biosynthesis. There is a wide variety of gene organization and light- and development-dependent regulatory mechanisms for the POR genes. In this study, a POR homologue, designated PjPORB, was isolated...
Key messageNot only the first systematic characterization ofCAOgene in bamboo species, but also the first attempt to study the relationship betweenCAOgene expression and bamboo leaf color variation. Abstract Chlorophyllide a oxygenase (CAO) converts chlorophyllide...
According to the characteristics of aero-engine's accelerating process, the control parameters and constraints are determined for the optimal acceleration control. A non-linear programming model is established to the optimal acceleration control for a certain turbofan engine, which high pressure rotor speed and high pressure turbine inlet temperature, are as the objective function of accelerating...
A newly isolated Bacillus megaterium with epoxide hydrolase activity resolved racemic glycidyl (o, m, p)-methylphenyl ethers to give enantiopure epoxides in 84–99% enantiomeric excess and with 21–73 enantiomeric ratios. The (S)-enantiomer was obtained from rac-glycidyl (o or m)-methylphenyl ether while the (R)-epoxides was obtained from glycidyl p-methylphenyl ether. The observations are explained...
