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 کاملReversal of the Light Inhibition of Pea Stem Growth by the Gibberellins.
when inactive, denatured, virus RNA is incorporated into a reconstituted nucleoprotein. It should be emphasized that the present data do not, in our opinion, permit a choice between the foregoing alternative explanations. The possibility that small amounts of otherwise inactive virus RNA components may, when incorporated into DNA-bearing nucleoproteins, render the polymer infectious is subject ...
متن کاملA new growth inhibitor, pisumin, involved in light inhibition of epicotyl growth of dwarf peas.
A new growth inhibitor, tentatively named pisumin, which increased under red light and remained at initial level or decreased when dwarf pea (Pisum sativum L. cv Progress No. 9) seedlings were transferred from red light to dark, has been isolated in the form of a colorless powder from light-exposed epicotyls of dwarf peas, and characterized partially as an aliphatic carboxylic acid (molecular w...
متن کاملEthylene is not involved in the blue light-induced growth inhibition of red light-grown peas.
Although the growth of intact plants is inhibited by irradiation with blue light, the growth rate of isolated stem segments is largely unaffected by blue light. We hypothesized that this loss of responsiveness was a result of ethylene production as part of the wounding response. However, we found no interaction between ethylene- and blue light-induced growth inhibition in dark- or red light-gro...
متن کاملGibberellins and Light Regulated Petiole Growth in Thlaspi arvense L.
Petiole growth in Thlaspi arvense L. was stimulated when a basic 8 hour photoperiod (4.20 milliwatts per square centimeter) was extended with low intensity light (0.16 milliwatt per square centimeter) from incandescent lamps. The day length extension was effective only when the light contained high proportions of far red light. Exogenous gibberellin A(3) (GA(3)) could partially substitute for t...
