effect of temperature on cuticular transpiration of isolated cuticular membranes and leaf discs.cuticular transpiration was measured in the temperature range between 10 degrees c and 55 degrees c using tritiated water and five species (vinca major l., prunus laurocerasus l., forsythia intermedia l., citrus aurantium l., and hedera helix l.). cuticular water permeabilities measured with isolated cuticular membranes were not different from cuticular water permeabilities measured with leaf discs. depending on the species cuticular water permeabilities increased by factors between 12 (v. major ...200111520878
effect of humidity on cuticular water permeability of isolated cuticular membranes and leaf disks.the effects of humidity on water permeability of astomatous, isolated cuticular membranes and leaf disks of citrus aurantium l., vinca major l., prunus laurocerasus l., hedera helix l. and forsythia intermedia (thunb.) vahl. were investigated by a new method using 3h2o. with isolated cuticular membranes of p. laurocerasus the isotope method resulted in values similar to those obtained by a well-established gravimetric method. cuticular water permeability significantly increased by factors of 2 t ...200111800392
heterologous expression of the flavonoid 3',5'-hydroxylase gene of vinca major alters flower color in transgenic petunia hybrida.flavonoid 3',5'-hydroxylase (f3'5'h) is the key enzyme for the expression of blue or purple flower color. a full-length cdna for the f3'5'h gene was cloned from petals of vinca major, and its genomic clone, designated vmfh1 (accession number ab078781 in the genbank/embl/ddbj databases), was isolated from leaves by a pcr-based strategy. nucleotide sequence analysis revealed that vmfh1 contains one intron and an open reading frame encoding a polypeptide of 506 amino acid residues. the deduced amin ...200414504908

causal role of xylella fastidiosa in oleander leaf scorch disease.abstract a lethal leaf scorch disease of oleander (nerium oleander) appeared in southern california in 1993. a bacterium, xylella fastidiosa, was detected by culturing, enzyme-linked immunoassay, and polymerase chain reaction in most symptomatic plants but not in symptomless plants or negative controls. inoculating oleanders mechanically with x. fastidiosa cultures from diseased oleanders caused oleander leaf scorch (ols) disease. the bacterium was reisolated from inoculated plants that became d ...199918944803
