Project description:Here we applied a novel approach to isolate nuclei from complex plant tissues (https://doi.org/10.1371/journal.pone.0251149), to dissect the transcriptome profiling of the hybrid poplar (Populus tremula × alba) vegetative shoot apex at single-cell resolution.

Project description:We performed that comprehensive identification of genes responsible for stress tolerance by analyzing the whole-genome expression profiles of poplar (Populus alba × P. glandulosa) leaves exposed to drought and salt stresses. Examination at the molecular level how this tree species responds to drought and salt stresses by regulating the expression of genes involved in signal transduction, transcriptional regulation, and stress responses.

Project description:Illumina technology was used to generate mRNA profiles of a time course of Laccaria bicolor S238N and Populus tremula x alba 717-1B4 in vitro ectomycorrhizal development. Total RNA was extracted, TruSeq mRNA Stranded libraries were constructed and and sequenced in triplicates (2 x 150 bp Illumina HiSeq3000) at the Genotoul sequencing facilities (Toulouse, France). Raw reads were trimmed for low quality (quality score 0.05), Illumina adapters and sequences shorter than 15 nucleotides and aligned to the L. bicolor v2 reference transcripts available at the JGI database https://mycocosm.jgi.doe.gov/Lacbi2/Lacbi2.home.html using CLC Genomics Workbench v8.

Project description:A transcriptome analysis of P. alba cambial zone was performed with the aim to unravel the gene network underlying the response to water deficit within the cambium and the differentiating derivatives cambial cells. Water stress was induced on one-year-old plant of Populus alba by withholding water for 9 days. At that time, leaf Ψpd fell down to -0,8 MPa resulting in a significant reduction of the stomatal conductance, CO2 assimilation, consistent increment of stem shrinkage and cessation of the radial growth. These effects were almost fully reversed by re-hydration. The water deficit resulted in changes in gene expression that affected a few functional categories as protein metabolism, cell wall metabolism, stress response, transporters and transcriptional regulation. The function of up- and down-regulated genes is discussed considering the physiological response of the plants to water deficit.

Project description:Microarray technology was used to assess transcriptome changes in poplar (Populus alba L.) under a realistic simulation of increased UV-B radiation. Plants were UV-Bbe (UV-B biologically effective radiation) supplemented with a dose of 6 kJ/m2/day for 12 hours per day and allowed to recover during the night. Poplar plants were UV-B treated using a refined controlled environment able to guarantee a realistic simulation of natural conditions, especially for light parameters such as presence of background UV-B radiation for control plants and balanced PAR/UV-A/UV-B ratio. A time course experiment was planned to look both at the rapid and delayed response of poplar to UVB; two time points after 3 h (T3h) and 30 h (6th hour of the third day of treatment, T30h) were considered. 4 independent biological replicates were analysed for each time point. Competitive hybridisations were carried out using the PICME 28K microarray. Keywords: Time course experiment, stress response

Keywords: Time course experiment, stress response Two condition experiment: UVB supplemented plants vs normal UV-B level plants. Biological replicates: 4 UVB suplemented plants, 4 control plants, two time points, one replicate per array. Dye swap between replicates.

Three-condition experiment, Stress vs. Control, Re-hydrated vs. Stress and Re-hydrated vs Control. Each sample consists of a pool of two plants independently grown and harvested. Two technical replicates are performed for each of the three treatments. One swap replicate per array.

Project description:The Populus homeobox gene ARBORKNOX1 was overexpressed behind the cauliflower mosaic virus 35S promoter in clone INRA 717 P. alba X P. tremula. The experiment here compares gene expression in defoliated stems of two independently transformed clones (mutants) versus wild type controls. Keywords: mutant versus wildtype

Project description:We performed that comprehensive identification of genes responsible for stress tolerance by analyzing the whole-genome expression profiles of poplar (Populus alba M-CM-^W P. glandulosa) leaves exposed to drought and salt stresses. Examination at the molecular level how this tree species responds to drought and salt stresses by regulating the expression of genes involved in signal transduction, transcriptional regulation, and stress responses. Genome-wide analysis was conducted in poplar leaves exposed to drought and salt stresses.The plants were acclimated in soil and grown for 6 weeks in controlled conditions in a growth room (16 h light; light intensity, 150 M-NM-<mol m-2sec-1; 24M-BM-0C). Plants with a height of about 15 cm were separately exposed to either drought or salt stress. Up- and down-regulated genes were identified, and their putative functions are discussed.
