Gibberellins and Light Inhibition of Stem Growth in Peas.
Light-induced inhibition of stem growth is a common phenomenon in plants. Particularly well investigated is the case of peas, Pisum sativum, mainly thanks to the work of Lockhart. Lockhart showed that growth of Alaska peas, a tall variety, was retarded when plants were transferred from darkness to low-intensity light but that, after a period of inhibition, the plants resumed growth at a rate eq...
متن کاملInhibition of stem elongation in cucumis seedlings by blue light requires calcium.
The effects of blue light and calcium on elongation of hypocotyl segments of Cucumber (Cucumis sativa L. cv Burpee's Pickler) were studied. Cucumber seedlings grown in dim red light showed a rapid decline in the rate of hypocotyl elongation when irradiated with high intensity (100 micromoles per square meter per second) blue light. In intact, 4-day-old seedlings the inhibition began within 2 mi...
متن کاملGenetic separation of phototropism and blue light inhibition of stem elongation.
Blue light-induced regulation of cell elongation is a component of the signal response pathway for both phototropic curvature and inhibition of stem elongation in higher plants. To determine if blue light regulates cell elongation in these responses through shared or discrete pathways, phototropism and hypocotyl elongation were investigated in several blue light response mutants in Arabidopsis...
متن کاملA study of gibberellin homeostasis and cryptochrome-mediated blue light inhibition of hypocotyl elongation.
Cryptochromes mediate blue light-dependent photomorphogenic responses, such as inhibition of hypocotyl elongation. To investigate the underlying mechanism, we analyzed a genetic suppressor, scc7-D (suppressors of cry1cry2), which suppressed the long-hypocotyl phenotype of the cry1cry2 (cryptochrome1/cryptochrome2) mutant in a light-dependent but wavelength-independent manner. scc7-D is a gain-o...
متن کاملArabidopsis Mutants Lacking Blue Light-Dependent Inhibition of Hypocotyl Elongation.
We have isolated a new class of photomorphogenic mutants in Arabidopsis. Hypocotyl elongation is not inhibited in the mutant seedlings by continuous blue light but is inhibited by far red light, indicating that these mutations are phenotypically different from the previously isolated long hypocotyl (hy) mutants. Complementation analysis indicated that recessive nuclear mutations at three geneti...
