Expression profiling of PpNAC1 RNAi Pinus pinaster plantlets

ABSTRACT: The transcriptome of PpNAC1 RNAi Pinus pinaster plantlets (60 days) were analyzed. Overall design: The samples are from two different PpNAC1 RNAi lines, PN5 and PN9 and were compared to wild type plantlets. Their trasncriptomes were analyzed using one color microarrays.

The transcriptional regulation of phenylalanine metabolism is particularly important in conifers, long-lived species that use large amounts of carbon in wood. Here, we show that the Pinus pinaster transcription factor, PpNAC1, is a main regulator of phenylalanine biosynthesis and utilization. A phylogenetic analysis classified PpNAC1 in the NST proteins group and was selected for functional characterization. PpNAC1 is predominantly expressed in the secondary xylem and compression wood of adult t  ...[more]
