Characterization and functional analysis of ABSCISIC ACID INSENSITIVE3-like genes from Physcomitrella patens.
Although the moss Physcomitrella patens is known to respond to abscisic acid (ABA) by activating gene expression, the transcriptional components involved have not been characterized. Initially, we used the ABA-responsive Em promoter from wheat linked to beta-glucuronidase (GUS) to determine whether ABI3/VP1, transcriptional regulators in the ABA-signaling pathway in angiosperms, were similarly ...
متن کاملBiosynthesis of C9-aldehydes in the moss Physcomitrella patens.
After wounding, the moss Physcomitrella patens emits fatty acid derived volatiles like octenal, octenols and (2E)-nonenal. Flowering plants produce nonenal from C18-fatty acids via lipoxygenase and hydroperoxide lyase reactions, but the moss exploits the C20 precursor arachidonic acid for the formation of these oxylipins. We describe the isolation of the first cDNA (PpHPL) encoding a hydroperox...
متن کاملCytokinin Biosynthesis in Mutants of the Moss Physcomitrella patens.
Three cytokinin-over-producing mutants of the moss, Physcomitrella patens, have been shown to convert [8-(14)C]adenine to N(6)-[(14)C](Delta(2)-isopentenyl)adenine, the presence of which was confirmed by thin layer chromatography, high performance liquid chromatography, and recrystallization to constant specific radioactivity. The labeled cytokinin was detected in the culture medium within 6 ho...

Arabidopsis and other species, this work has also begun to reveal the levels of evolutionary conservation within the flowering plants and even outside the plant kingdom. What does the future hold for Antirrhinum research? In addition to its continuing role as a genetic model for plant biology and development, several new experimental avenues are beginning to be explored with Antirrhinum. A majo...
متن کاملIdentification and functional characterization of the moss Physcomitrella patens delta5-desaturase gene involved in arachidonic and eicosapentaenoic acid biosynthesis.
The moss Physcomitrella patens contains high levels of arachidonic acid and lesser amounts of eicosapentaenoic acid. Here we report the identification and characterization of a delta5-desaturase from P. patens that is associated with the synthesis of these fatty acids. A full-length cDNA for this desaturase was identified by data base searches based on homology to sequences of known delta5-desa...
