Abstract:
... We report here the synthesis and biological activity of a new persistent abscisic acid (ABA) analog, 8'-methylene ABA. This ABA analog has one additional carbon atom attached through a double bond to the 8'-carbon of the ABA molecule. (+)-8'-Methylene ABA is more active than the natural hormone (+)-ABA in inhibiting germination of cress seed and excised wheat embryos, in reducing growth of suspens ...

Abstract:
... AFLP (amplified fragment length polymorphism) fingerprinting of cultivars of bread wheat (Triticum aestivum) and some of its wild relatives has allowed the efficient detection of large numbers of polymorphic amplified fragments. While the reproducibility of fingerprints in repeated experiments is high, pattern differences were observed between fingerprints obtained from seed and leaf DNA template ...

Abstract:
... Application of abscisic acid (ABA) to dark-grown wheat (Triticum aestivum L.) roots interfered the cell wall hardening of coleoptiles during several days of the treatment. Although the mounts of wall-bound diferulic (DFA) and ferulic (FA) acids in coleoptiles increased as the coleoptiles grew, ABA substantially reduced their increases. When ABA was removed, however, these contents increased and re ...

Abstract:
... We investigated the role of actin microfilaments in nonhost resistance of higher plants. Here we present several lines of evidence to indicate that microfilaments are indeed involved in blocking fungal penetration of nonhost plants. Erysiphe pisi, a pathogen of pea, normally fails to penetrate into nonhost plants such as barley, wheat, cucumber and tobacco. When tissues of these nonhost plants wer ...

Abstract:
... Previous studies have identified wheat (Triticum aestivum L.) chromosome substitution lines between ‘Cheyenne’ (CNN) and ‘Wichita’ (WI) that contain quantitative trait loci (QTLs) affecting yield and yield components, anthesis date, plant height, and grain volume weight. However, chromosome substitution lines can only identify additive or epistatic gene action. In this study, hybrids between CNN a ...

There are no known reports of the effect of this translocation in durum wheat (Triticum turgidum L.), however. The objective of this study was to determine the effect of the T1BL.1RS chromosome on grain yield, yield ...

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 ...

The slurry was applied with trail hoses on the soil below the canopy or by a splash plate technique spreading the slurry on both plants and soil. The two application techniques were compared in parallel experiments of 7 d dura ...

Abstract:
... Tissue analysis of plant material is used to estimate the level of sufficiency of deficiency of any particular nutrient. Published values of ammonium-ammonia reported in plant cell extracts would have been toxic to plants, if these values are really present in the cell. We believe that the ammonia determined in plant tissue is actually ammonium produced by the decomposition of soluble amino compou ...
