Journal ArticleDOI
Novel and mechanical stress-responsive MicroRNAs in Populus trichocarpa that are absent from Arabidopsis.
TL;DR: It is shown that plant miRNAs can be induced by mechanical stress and may function in one of the most critical defense systems for structural and mechanical fitness.
Journal ArticleDOI
Combinatorial modification of multiple lignin traits in trees through multigene cotransformation
TL;DR: The results suggest that this multigene cotransfer system should be broadly useful for plant genetic engineering and functional genomics.
Journal ArticleDOI
Coniferyl aldehyde 5-hydroxylation and methylation direct syringyl lignin biosynthesis in angiosperms
Keishi Osakabe,Cheng Chung Tsao,Laigeng Li,Jacqueline L. Popko,Toshiaki Umezawa,Daniel T. Carraway,Richard H. Smeltzer,Chandrashekhar P. Joshi,Vincent L. Chiang +8 more
TL;DR: Cloned cDNAs encoding a cytochrome P450 monooxygenase and a caffeate O-methyltransferase from sweetgum and COMT converted coniferyl aldehyde to sinapyl alde Hyde, suggesting a CAld5H/COMT-mediated pathway from guaiacyl to syringyl monolignol biosynthesis via conifldehyde that contrasts with the generally accepted route to Sinapate via ferulate.
Journal ArticleDOI
The Last Step of Syringyl Monolignol Biosynthesis in Angiosperms Is Regulated by a Novel Gene Encoding Sinapyl Alcohol Dehydrogenase
Laigeng Li,Xiao Fei Cheng,Jacqueline Leshkevich,Toshiaki Umezawa,Toshiaki Umezawa,Scott A. Harding,Vincent L. Chiang +6 more
TL;DR: The isolation of a novel aspen gene (PtSAD) encoding sinapyl alcohol dehydrogenase (SAD), which is phylogenetically distinct from aspen CAD, suggests that in addition to CAD, discrete SAD function is essential to the biosynthesis of syringyl monolignol in angiosperms.
Journal ArticleDOI
The cellulose synthase gene superfamily and biochemical functions of xylem-specific cellulose synthase-like genes in Populus trichocarpa.
TL;DR: Using Populus trichocarpa as a model angiosperm tree, a systematic analysis in various tissues of the absolute transcript copy numbers of cellulose synthase superfamily genes, the cellulose synthetase (CesA) and the hemicellulose-related cellulOSE synthase-like (Csl) genes is reported.
