TranscriptomicsTranscriptome analyses of the Laccaria bicolor-Populus trichocarpa mycorrhiza development
Illumina GAIIx technology was used to generate mRNA profiles from the ectomycorrhizal fungi Laccaria bicolor colonizing roots of Populus trichocarpa. Samples were taken after two, four and 12 weeks of contact in order to identify mycorrhiza-regulated transcripts. 37bp reads were generated and aligne...

TranscriptomicsPtr-miR397a is a negative regulator of laccase genes affecting lignin content in Populus trichocarpa
Laccases were proposed to catalyze the oxidative polymerization of monolignols. We identified 49 laccase gene models in Populus trichocarpa, of which 29 were predicted to be targets of ptr-miR397a. We overexpressed Ptr-MIR397a in transgenic P. trichocarpa. In each of all 9 transgenic lines tested, 1...

TranscriptomicsSND1 Transcription Factor-Directed Quantitative Functional Hierarchical Genetic Regulatory Network in Wood Formation in Populus trichocarpa
We focused on RNA-seq-based full transcriptome responses to PtrSND1-B1 overexpression at 7, 12, and 25 h in stem defferentiating xylem (SDX) protoplasts We transfected PtrSND1-B1 and sGFP into stem differentiating xylem protoplasts and performed RNA-seq to reveal the whole transcriptome.

TranscriptomicsComparison of gene expression in roots from Populus trichocarpa and Populus deltoides colonized with Laccaria bicolor
The majority of trees live in association with symbiotic fungi, which facilitate their access to soil nutrients. The ectomycorrhizal symbiosis represents a complex biological system involving multifaceted interactions between the two partners. The establishment of the symbiosis depends on various co...

TranscriptomicsA Genome-Wide Characterization of New and Drought Stress Responsive MicroRNAs in Populus euphratica
We present an efficient method to genome-wide discover new and drought stress responsive miRNAs in P. euphratica. High throughput sequencing of P. euphratica leaves found 197 conserved miRNAs between P. euphratica and Populus trichocarpa. Meanwhile, 189 new miRNAs which belonged to 120 families were...

TranscriptomicsComparative physiology and transcriptional networks underlying the heat shock response in Populus trichocarpa, Arabidopsis thaliana and Glycine max [Arabidopsis]
The heat shock response continues to be layered with additional complexity as interactions and cross-talk among heat shock proteins, the reactive oxygen network and hormonal signaling are discovered. However, comparative analyses exploring variation in each of these processes among species remains r...

TranscriptomicsGene expression in leaves of a Populus trichocarpa and Populus deltoides pseudo-backcross population
A microarray analysis of whole-genome gene expression in leaves was carried out in a (Populus trichocarpa X Populus deltoides) X Populus deltoides pseudo-backcross pedigree. Genetic variation in gene expression was quantified for 55,793 predicted gene models based on a single probe per gene. Result...

TranscriptomicsAdventitious root formation in Populus trichocarpa involves complex cellular events
Stem cuttings of P. trichocarpa (clone 101-74) were rooted in liquid medium without growth regulators (basal medium). The first emerging roots were observed on cuttings 6 days after the start of culture. The highest average root number per cutting (10 ± 2 roots/cutting) was obtained after 14 days. ...
