Cytosolic and plastoglobule-targeted carotenoid dioxygenases from Crocus sativus are both involved in beta-ionone release.

Saffron, the processed stigma of Crocus sativus, is characterized by the presence of several apocarotenoids that contribute to the color, flavor, and aroma of the spice. However, little is known about the synthesis of aroma compounds during the development of the C. sativus stigma.

Characterization of AtNST-KT1, a novel UDP-galactose transporter from Arabidopsis thaliana.

Nucleotide sugar transporters (NST) mediate the transfer of nucleotide sugars from the cytosol into the lumen of the endoplasmatic reticulum and the Golgi apparatus. Because the NSTs show similarities with the plastidic phosphate translocators (pPTs), these proteins were grouped into the TPT/NST superfamily. In this study, a member of the NST-KT family, AtNST-KT1, was functionally characterized by expression of the corresponding cDNA in yeast cells and subsequent transport experiments.

Identification of genes in cassava that are differentially expressed during infection with Xanthomonas axonopodis pv. manihotis.

SUMMARY The cDNA-amplified fragment length polymorphism approach was used to identify differentially expressed transcripts from cassava infected by Xanthomonas axonopodis pv. manihotis (Xam). Approximately 3600 transcript-derived fragments (TDFs) were screened of which 340 were isolated.
