Hormonal control of a gene encoding a putative PDR5-like ABC transporter in periwinkle
摘要:
ATP binding cassette (ABC) transporters retain increasing attention since their implication in multidrug resistance has been demonstrated in several prokaryotic and eukaryotic cells. Many ARC proteins are known in various organisms but only few in higher plants. We report here on the characterization of a partial 955 bp clone (Cr-ABC1) isolated from a Catharanthus roseus cDNA library, which shows high homology (65% identity) with the TUR2 cDNA previously isolated from the water lens Spirodela polyrrhiza. Accumulation of Cr-ABC1 transcripts in cultured C. roseus cells was enhanced by cytokinin or methyl jasmonate addition to, or auxin suppression from the culture medium. In whole plants, the gene was mainly expressed in flowers.

The ruthenium diacetate complexes ligated by chiral spirobifluorene diphosphines (SFDP) were very effective catalysts for the asymmetric hydrogenation of tiglic acid derivatives and α-methylcinnamic acid derivatives with high activities and excellent enantioselectivities (up to 98 % ee). The α-aryloxybutenoic acids can also be hydrogenated by these catalysts to provide the corresponding saturated α-aryloxybutanoic

The detailed account of an asymmetric Nazarovcyclization that leads to α-hydroxycyclopentenones bearing either vicinal, all-carbon atom quaternary centers, or vicinalquaternary and tertiary centers is described. The all-aliphatic examples represent the greatest challenge as the dienone starting materials are not activated toward cyclization by an aryl group. The rational design and optimization of
