TL;DR: Investigation of the high number of STS genes in grapevine finds a few sites under different selection pressures in CHS and STS sequences, whose potential functional consequences are discussed using a structural model of a typical STS from grapevine that is developed.

TL;DR: Evidence is provided for developmental control of isoprenoid biosynthesis occurring in plastids and that cytoplasmic isoprene biosynthesis is regulated, in part, by environmental signals.

TL;DR: Comparison of the expression pattern of the genes encoding geranylgeranyl pyrophosphate synthase, phy toene synthase and phytoene desaturase revealed that these genes are not co-regulated during pepper fruit ripening, and nucleotide sequence of the 3'-untranslated region of the pepper cDNA suggests that this region was subjected to complex recombination events.

TL;DR: Antibodies raised against the purified polypeptide selectively precipitated thephytoene and the phytofluene desaturase activities, thus demonstrating that the enzyme is a bifunctional flavoprotein.

TL;DR: The polymerase chain reaction analysis of potato plants, transformed with capsanthin capsorubin synthase ccs, revealed the presence of a highly related gene, suggesting that the novel enzyme catalyzes a mechanistically similar reaction.
