A Temporarily Red Light-Insensitive Mutant of Tomato Lacks a Light-Stable, B-Like Phytochrome.
We have selected four recessive mutants in tomato (Lycopersicon esculentum Mill.) that, under continuous red light (R), have long hypocotyls and small cotyledons compared to wild type (WT), a phenotype typical of phytochrome B (phyB) mutants of other species. These mutants, which are allelic, are only insensitive to R during the first 2 days upon transition from darkness to R, and therefore we ...
متن کاملPhytochrome Modification and Light-enhanced, In Vivo-induced Phytochrome Pelletability.
Phytochrome that was induced by red irradiation in vivo to pellet with subcellular material and that was released from the pellet by removal of divalent cations exhibited altered characteristics. Compared to phytochrome extracted in a soluble red-absorbing form from etiolated tissue, pelleted and released phytochrome, which was also assayed in the red-absorbing form even though pelleted in the ...
متن کاملLight perception and signalling by phytochrome A.
In etiolated seedlings, phytochrome A (phyA) mediates very-low-fluence responses (VLFRs), which initiate de-etiolation at the interphase between the soil and above-ground environments, and high-irradiance responses (HIR), which complete de-etiolation under dense canopies and require more sustained activation with far-red light. Light-activated phyA is transported to the nucleus by FAR-RED ELONG...
متن کاملPlants under Continuous Light: A Review
In this review an attempt has been made to analyze the results of the studies that explored the changes in the growth and development of plants exposed to continuous light published since the 1930s, including papers that are available in Russian only. Potential benefits of using a 24-h photoperiod for the production of greenhouse crops, transplant production in closed controlled environment sys...
متن کاملNuclear and cytosolic events of light-induced, phytochrome-regulated signaling in higher plants.
Plants as sessile organisms cannot walk away but have to adapt to changes in their natural environments. Light is obviously the most important external factor, being the energy source. To regulate their fitness, the photosynthetic capacity of plants must be adapted to changes in the ambient light environment. Therefore, plants have evolved a large set of photoreceptors to monitor light quality ...
