Phytochrome control of maize coleoptile section elongation: the role of cell wall extensibility.
Maize (Zea mays) coleoptile section cell wall extensibility was found to be stimulated by red light. This stimulation was largely removed by simultaneous or immediately subsequent far-red treatment. Qualitatively similar patterns of response occurred at 0 C and 20 C. Plastic extensibility responded more than elastic extensibility after red light treatment. Red-induced extensibility increases we...
متن کاملIdentification of genes involved in cell wall biogenesis in grasses by differential gene expression profiling of elongating and non-elongating maize internodes
Despite the economic importance of grasses as food, feed, and energy crops, little is known about the genes that control their cell wall synthesis, assembly, and remodelling. Here a detailed transcriptome analysis that allowed the identification of genes involved in grass cell wall biogenesis is provided. Differential gene expression profiling, using maize oligonucleotide arrays, was used to id...
متن کاملAuxin-induced Changes in Avena Coleoptile Cell Wall Composition.
Sugar and uronic acid residues were derived from wall polysaccharides of oat (Avena sativa, var. Victory) coleoptiles by means of 2 N trifluoroacetic acid, 72% sulfuric acid, or enzymic hydrolysis. The products of hydrolysis were reduced and acetylated to form alditol acetates which were analyzed using gas chromatography. Time-course studies of auxin-promoted changes in various wall fractions i...
متن کامل-Stimulated Exocytosis in Maize Coleoptile Cells
in the cytoplasm ([Ca 2 1 ] cyt ) were interpreted as representing changes in [Ca 2 1 ] cyt –sensitive exocytosis and endocytosis. A continuous increase in [Ca 2 1 ] cyt resulted in a sigmoidal increase in C m values with a half-maximal concentration at z 1 m M. The steep increase in C m values was followed by a variable slow phase in changing C m values. When [Ca 2 1 ] cyt increased at a rate ...
متن کاملDistribution and metabolism of protein-bound hydroxyproline in an elongating tissue, the Avena coleoptile.
A study has been made of the distribution and metabolism of protein-bound hydroxyproline in an elongating tissue, the excised Avena coleoptile. The hydroxyproline-containing proteins of this tissue have been separated into 3 fractions on the basis of their solubilities. The cytoplasmic, trichloroacetic acid-insoluble proteins (S-fraction) contain the bulk of the proline of the cells but only 20...
