Genes expression during stem growth of Populus alba x Populus tremula var. glandulosa

Project description:To obtain genes expression in different parts of 84k poplar stems, transcriptome sequencing was performed using Illumina Novaseq 6000 second-generation sequencing platform from Shanghai BIOZERON Co. Ltd (www.biozeron.com). Selecte three stem segments of plants REPEAT 1, 2 and 3 with good and similar growth to use: 2nd-3rd internodes (poplar stem top: PST1, PST2, PST3); 9th-10th internodes (poplar stem middle: PSM1, PSM2, PSM3); 14th-15th internodes (poplar stem bottom: PSB1, PSB2, PSB3). [Or the three repeating organisms are also called poplar A, B, C. From top to bottom, the three parts of the stem are also called stem 1, 2, 3.]

Analysis of Expression Profile of Over-expressed Brassinolide Synthase DET2 in Poplar

Project description:We overexpressed the brassinolide synthase DET2 in 84K poplar and obtained an overexpression material.It was found that the brassinolide content of the overexpression material increased significantly.And it was found that the plant height, diameter, and number of internodes of the overexpression material increased significantly.However,the mechanism of this phenotype is unknown.We collected two-month-old DET2 overexpression material and 84K wild-type material in three parts, apex,cambium,and xylem,and conducted high-throughput sequencing.The sequencing results were mined, and the difference genes that were significantly changed in the DET2 overexpression material and the 84K wild-type material were found.Find out how the increase in brassinolide content promotes the development of wood.

Ethylene and jasmonic acid act as negative modulators during mutualistic symbiosis between Laccaria bicolor and Populus roots

Project description:The Poplar transcriptome was analyzed in mycorrhizal root tips in contact with Laccaria bicolor for 2 weeks. During mycorrhization the roots were treated with either 250µm ACC, 10nM JA or 500µM SA and compared to untreated mycorrhiza or control roots without contact to L. bicolor. In addition the poplar mutants 35S::PttACO1 and 35S::Atetr1 were used

affy_popsec_nancy_pophydro_roots_poplar -Molecular bases of acclimation and adaptation to water deficit in poplar

Project description:affy_popsec_nancy_pophydro_roots_poplar - This project aims to identify genes of interest for control of root growth in response to water deficit in a tree species: poplar. We look for genes and gene expression networks related to drought stress. We intend to analyse the transcriptome in root apices of cuttings grown in hydroponics and osmotically stressed with PEG. Root apex is the location of root elongation and these analyses intend to identify genes involved in the control of cell expansion and thus of root elongation. Indeed, root growth maintenance in response to water shortage contributes to plant tolerance to water deficit.-Poplar cuttings (cv Soligo) were grown in hydroponics. A moderate water deficit was applied by adding PEG to the nutrient solution (200g/l). After 3 days, the apex (1 cm-long) of the roots of each cutting were collected. For control and stressed treatments, RNAs were extracted from two pools of 5 to 9 roots (issued from 2 to 5 cuttings). A pool is considered as one biological replicate and corresponds to one Affymetrix slide. Keywords: treated vs untreated comparison 4 arrays - poplar

Modulation of Polar Auxin Transport Identifies the Molecular Determinants of Source-Sink Carbon Relationships and Sink Strength in Poplar

Project description:Source-to-sink carbon (C) allocation driven by the sink strength, i.e., the ability of a sink organ to import C, plays a central role in tissue growth and biomass productivity. However, molecular drivers of sink strength have not been thoroughly characterized in trees. Auxin, as a major plant phytohormone, regulates the mobilization of photoassimilates in source tissues and elevates the translocation of carbohydrates toward sink organs, including roots. In this study, we used an ‘auxin-stimulated carbon sink’ approach to understand the molecular processes involved in the long-distance source-sink C allocation in poplar. Poplar cuttings were foliar sprayed with polar auxin transport modulators, including auxin enhancers (AE) (i.e., IBA and IAA) and auxin inhibitor (AI) (i.e., NPA), followed by a comprehensive analysis of leaf, stem, and root tissues using biomass evaluation, phenotyping, C isotope labeling, metabolomics, and transcriptomics approaches. Auxin modulators altered root dry weight and branching pattern, and AE increased photosynthetically fixed C allocation from leaf to root tissues. The transcriptome analysis identified highly expressed genes in root tissue under AE condition including transcripts encoding polygalacturonase and β-amylase that could increase the sink size and activity. Metabolic analyses showed a shift in overall metabolism including an altered relative abundance levels of galactinol, and an opposite trend in citrate levels in root tissue under AE and AI conditions. In conclusion, we postulate a model suggesting that the source-sink C relationships in poplar could be fueled by mobile sugar alcohols, starch metabolism-derived sugars, and TCA-cycle intermediates as key molecular drivers of sink strength.
