Phytochrome Control of Cell Wall-bound Hydroxyproline Content in Etiolated Pea Epicotyls.
The red light inhibition of growth of the intact pea (Pisum sativum L. cv. Alaska) third internode was correlated with an increase in the content of cell wall-bound hydroxyproline. These changes were detected 3 hours after irradiation, and possibly at 1 hour. Far red light reversed the effects of red light. The iron chelator alpha,alpha'-dipyridyl reversed the red light effects on both growth a...
متن کاملControl by phytochrome of C-sucrose incorporation into buds of etiolated pea seedlings.
When etiolated pea epicotyls are excised immediately above the cotyledons and dipped basally into (14)C-sucrose, their terminal buds respond to red light by increased growth (IG) and enhanced incorporation of sucrose (EIS). Both phenomena are phytochrome controlled, showing typical kinetics, reversal by far-red light, escape from photochemical control and limitation to leaf tissue. EIS is of gr...
متن کاملEffects of calcium and kinetin on growth and cell wall composition of pea epicotyls.
Kinetin and CaCl(2), in the presence of indoleacetic acid, promoted lateral expansion of epicotyls of decapitated and derooted Alaska pea seedlings (Pisum sativum L.) and inhibited their elongation. This growth response was correlated with the development of cell walls unusually rich in pectic uronic acids. Epicotyls in calcium-auxin solutions continued to enlarge and to add new wall material l...
متن کاملEthylene-induced lateral expansion in etiolated pea stems : kinetics, cell wall synthesis, and osmotic potential.
Treatment of etiolated pea (Pisum sativum L.) internode tissue with ethylene gas inhibits elongation and induces lateral expansion. Precise kinetics of the induction of this altered mode of growth of excised internode segments were recorded using a double laser optical monitoring device. Inhibition of elongation and promotion of lateral expansion began after about 1 hour of treatment and achiev...
متن کاملPhytochrome, nitrate movement, and induction of nitrate reductase in etiolated pea terminal buds.
The role of phytochrome in the induction of nitrate reductase of etiolated field peas (Pisum arvense L.) was examined. Terminal bud nitrate concentration increased in darkness, and the increase correlated with induction of nitrate reductase following brief exposure of intact plants to red, blue, far red, and white lights. Brief light exposure of intact plants stimulated nitrate uptake and induc...
