A 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 کاملPolyribosomes from peas: an improved method for their isolation in the absence of ribonuclease inhibitors.
Profiles of polyribosomes were obtained from etiolated stem segments of Pisum sativum L. var. Alaska isolated in various buffers. Tissue homogenized in a medium containing 0.2 m tris-HCl, pH 8.5, 0.2 m sucrose, 30 mm MgCl(2), and 60 mm KCl yielded polyribosomes exhibiting far less degradation than tissue homogenized in conventional media containing tris-HCl at lower ionic strength and pH. A fur...
متن کاملRadioactive gibberellin a(5) and its metabolism in dwarf peas.
Radioactive gibberellin A(5) ((3)H-GA(5)) was synthesized from gibberellic acid. When it was applied to dwarf peas grown in the dark, an average of 3% was converted to another acid gibberellin within 48 hours. The biological activity of the metabolite did not account for the response to applied GA(5). GA(5) is therefore assumed to be biologically active per se.(3)H-GA(5) did not appear to form ...
متن کاملGrafting and gibberellin effects on the growth of tall and dwarf peas.
Tall peas var. Alaska and dwarf peas var. Progress No. 9 were grafted onto their own roots or reciprocally grafted to determine the rootstock effect on the growth of the stem. In all cases the grafted stems grew the same as their ungrafted controls regardless of which rootstock they were grown on. When similarly grafted plants were supplied with gibberellic acid, good graft unions did not inhib...
متن کاملElectrophoretic Analysis of Histones from Gibberellic Acid-treated Dwarf Peas.
Histones from the epicotyls of light-grown dwarf peas (Pisum sativum L. cv. Little Marvel) which had been treated with gibberellic acid were compared to histones from control dwarf peas by the method of polyacrylamide gel electrophoresis. The histone complements were found to be unaltered in the electrophoretic mobility and relative quantity of the individual fractions. The ratio of histone to ...
