The endogenous ABA contents of dormant and nondormant barley grains were determined following application of different compounds to break dormancy. The chemicals used for breaking of dormancy in intact dormant grains were weak and strong acids, alcohols,. hydrogen peroxide, cyanide, nitrate, salicylic acid, gibberellic acid and fusicoccin. The...

Mitogen-activated protein kinase and abscisic acid signal transduction

Heimovaara-Dijkstra, S. (author), Testerink, C. (author), Wang, M. (author), Centraal Instituut voor Voedingsonderzoek TNO TNO Voeding (author)

The phytohormone abscisic acid (ABA) is a classical plant hormone, responsible for regulation of abscission, diverse aspects of plant and seed development, stress responses and germination. It was found that ABA signal transduction in plants can involve the activity of type 2C-phosphatases (PP2C), calcium, potassium, pH and a transient...

Spatial and temporal regulation of DNA fragmentation in the aleurone of germinating barley

Wang, M. (author), Oppedijk, B.J. (author), Caspers, M.P.M. (author), Lamers, G.E.M. (author), Boot, M.J. (author), Geerlings, D.N.G. (author), Bakhuizen, B. (author), Meijer, A.H. (author), van Duijn, B. (author), Centraal Instituut voor Voedingsonderzoek TNO (author)

During germination of barley grains, the appearance of DNA fragmentation started in aleurone cells near the embryo and extended to the distal end in a time-dependent manner. DNA fragmentation was demonstrated to occur only after the expression of α-amylase mRNA in the aleurone layer. In addition, cell wall degradation started in cells near the...

The construction of a photoaffinity probe based on abscisic acid is described. A strategy based on C-4′-tethering of aromatic hydrazides led to abscisic acid 4′-(3″-azido-4″-hydroxybenzoylhydrazide). This compound is of moderate biological activity in cereal aleurone assays and was readily iodinated with chloramine T and sodium iodide,...

Inhibition of barley grain germination by light

Roth-Bejerano, N. (author), van der Meulen, R.M. (author), Wang, M. (author), Gaubius Instituut TNO (author)

Intact grains of barley (Hordeum distichum cv. Triumph) germinated rapidly in the dark or when exposed to brief daily light breaks in the temperature range 15-25°C, although germination proceeded less rapidly at low temperatures. Prolonged illumination (16 h/day) or continuous light inhibited germination of grains most effectively when...

Effects of modulation of calcium levels and calcium fluxes on ABA- induced gene expression in barley aleurone

van der Meulen, R.M. (author), Visser, K. (author), Wang, M. (author)

We present data to elucidate the involvement of calcium ions in abscisic acid (ABA)-induced gene expression. Modulation of external calcium concentrations was able to affect ABA-induced specific RAB gene expression. At a constant ABA level with increasing extracellular calcium level, an increasing RAB mRNA expression was measured. In barley...
