1. Accumulation of 19-kDa plasma membrane polypeptide during induction of freezing tolerance in wheat suspension-cultured cells by abscisic acid

Author:
Koike, M.; Takezawa, D.; Arakawa, K.; Yoshida, S.

Abstract:
... Suspension-cultured cells derived from immature embryos of winter wheat (Triticum aestivum L. cv. Chihoku) were used in experiments designed to obtain clues to the mechanism of the ABA-induced development of freezing tolerance. Cultured cells treated with 50 micromolar ABA for 5 d at 23 degrees C acquired the maximum level of freezing tolerance (LT50; -21.6 degrees C). The increased freezing toler ...

2. Al partitioning patterns and root growth as related to Al sensitivity and Al tolerance in wheat

Triticum aestivum; roots; aluminum; quantitative analysis; dose response; phytotoxicity; cultivars; translocation (plant physiology); biological resistance
Abstract:
... Studies of Al partitioning and accumulation and of the effect of Al on the growth of intact wheat (Triticum aestivum L.) roots of cultivars that show differential Al sensitivity were conducted. The effects of various Al concentrations on root growth and Al accumulation inthe tissue were followed for 24 h. At low external Al concentrations, Al accumulation in the root tips was low and root growth w ...

Abstract:
... Incorporation of 35S into protein is reduced by exposure to Al in wheat (Triticum aestivum), but the effects are genotype-specific. Exposure to 10 to 75 micromolars Al had little effect on 35S incorporation into total protein, nuclear and mitochondrial protein, microsomal protein, and cytosolic protein in the Al-resistant cultivar PT741. In contrast, 10 micromolars Al reduced incorporation by 21 t ...

4. Differential induction of lipoxygenase isoforms in wheat upon treatment with rust fungus elicitor, chitin oligosaccharides, chitosan, and methyl jasmonate

Abstract:
... A glycopeptide elicitor prepared from germ tubes of the rust fungus Puccinia graminis Pers. f. sp. tritici Erikss. & Henn (Pgt),as well as chitin oligosaccharides, chitosan, and methyl jasmonate (MJ) stimulated lipoxygenase (LOX) activity (E.C. 1.13.11.12) in wheat (Triticum aestivum) leaves. Immunoblot analysis using anti-LOX antibodies revealed the induction of 92- and 103-kD LOX species after P ...

Abstract:
... The importance of the two chiral centers at C-3 and C-7 in the molecular structure of jasmonic acid in plant responses was investigated. We separated methyl jasmonate (MeJA) into (3R)- and (3S)-isomers with a fixed stereochemistry at C-3, but epimerization at C-7 is possible. The four isomers of the nonepimerizable analog 7-methyl MeJA were synthesized. These six esters and their corresponding aci ...

Abstract:
... Application of 60 mM polyethylene glycol (PEG) to dark-grown wheat (Triticum aestivum L.) roots substantially reduced growth of coleoptiles. However, when PEG was removed, the growth rate of these coleoptiles greatly increased. Cell walls of stressed coleoptiles remained loosened as compared with those of unstressed ones. The osmotic potential of the stressed coleoptiles decreased to that of the 6 ...
