The degree of tubulin polymerization in cotton (Gossypium hirsutum L. cv Acala) cotyledonary tissue was estimated by radioimmunoassay which measured the amount of a tubulin-like factor. It was assumed that the release of this tubulin-like factor indicated depolymerization of microtubules. Exposure to chilling resulted in complete release of the tubulin-like factor. Pretreatment with abscisic ac...
Abscisic acid (ABA) controls many physiological processes and mediates adaptive responses to abiotic stresses. The ABA signaling mechanisms for abscisic acid receptors PYR/PYL/RCAR (PYLs) were reported. However, it remains unclear whether the molecular mechanisms are suitable for other PYLs. Here, complex structures of PYL3 with (+)-ABA, pyrabactin and HAB1 are reported. An unexpected trans-hom...
Magnesium chelatase is the first unique enzyme of the chlorophyll biosynthetic pathway. It is composed of three gene products of which the largest is 150 kD. This protein was recently identified as an abscisic acid receptor in Arabidopsis (Arabidopsis thaliana). We have evaluated whether the barley (Hordeum vulgare) magnesium chelatase large subunit, XanF, could be a receptor for the phytohormo...
Along with sugar accumulation and colour development, softening is an important physiological change during the onset of ripening in fruits. In this work, we investigated the relationships among major events during softening in grape (Vitis vinifera L.) by quantifying elasticity in individual berries. In addition, we delayed softening and inhibited sugar accumulation using a mechanical growth-p...
The pattern of expression of two genes coding for proteins rich in proline, HyPRP (hybrid proline-rich protein) and HRGP (hydroxyproline-rich glycoprotein), has been studied in maize (Zea mays) embryos by RNA analysis and in situ hybridization. mRNA accumulation is high during the first 20 d after pollination, and disappears in the maturation stages of embryogenesis. The two genes are also expr...
Cucumber hypocotyls were extracted and the extract centrifuged at 100,000g to yield a supernatant or cytosol fraction. Binding of [(3)H]-gibberellin(4) (GA(4)) to soluble macromolecular components present in the cytosol was demonstrated at 0 C by Sephadex chromatography. Binding assays performed with cytosol that had been preheated or incubated with protease, DNase, RNase, or phospholipase A or...
