Phytochrome regulation of greening in barley-effects on chlorophyll accumulation.
Red light treatment of dark-grown 6-day-old barley seedlings (Hordeum vulgare L.) strongly reduces the lag in chlorophyll accumulation in subsequent white light over that found in dark control seedlings placed under white light. Fluence-response studies show that the effect has both very low fluence and low fluence components. Kinetic studies indicate that the reduction in lag begins immediatel...
متن کاملThe altered gravitropic response of the lazy-2 mutant of tomato is phytochrome regulated.
Shoots of the lazy-2 (lz-2) gravitropic mutant of tomato (Lycopersicon esculentum Mill.) have a normal gravitropic response when grown in the dark, but grow downward in response to gravity when grown in the light. Experiments were undertaken to investigate the nature of the light induction of the downward growth of lz-2 shoots. Red light was effective at causing downward growth of hypocotyls ...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولNitric Oxide, Ethylene, and Auxin Cross Talk Mediates Greening and Plastid Development in Deetiolating Tomato Seedlings.
The transition from etiolated to green seedlings involves the conversion of etioplasts into mature chloroplasts via a multifaceted, light-driven process comprising multiple, tightly coordinated signaling networks. Here, we demonstrate that light-induced greening and chloroplast differentiation in tomato (Solanum lycopersicum) seedlings are mediated by an intricate cross talk among phytochromes,...
