Transcriptome analyses of the Laccaria bicolor-Populus trichocarpa mycorrhiza development

ABSTRACT: 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 aligned to the Populus trichocarpa (http://www.phytozome.net/poplar.php) and the Laccaria bicolor (http://genome.jgi-psf.org/Lacbi2/Lacbi2.home.html) reference genomes using CLC Genomics Workbench 6. mRNA profiles from Populus trichocarpa roots colonized by Laccaria bicolor for two, four and 12 weeks as well as from control roots and free-living mycelium were generated by using one lane of 37 bp Illumina GAIIx sequencing per sample.

Molecular plant-microbe interactions : MPMI 20140601 6

Within boreal and temperate forest ecosystems, the majority of trees and shrubs form beneficial relationships with mutualistic ectomycorrhizal (ECM) fungi that support plant health through increased access to nutrients as well as aiding in stress and pest tolerance. The intimate interaction between fungal hyphae and plant roots results in a new symbiotic "organ" called the ECM root tip. Little is understood concerning the metabolic reprogramming that favors the formation of this hybrid tissue in ...[more]

A Genome-Wide Characterization of New and Drought Stress Responsive MicroRNAs in Populus euphratica

Project description: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 identified, a large increasing to the number of P. euphratica miRNAs. Target prediction and degradome sequencing verification of 22 new and 21 conserved miRNA targets showed these targets were involved in multiple biological processes, including transcription regulation and response to stimulus. Furthermore, comparison of high-throughput sequencing with miRNA microarray profiling data indicated that 104 miRNA sequences were up-regulated, while 27 were down-regulated under drought stress. This preliminary characterization based on our findings provided a framework for future analysis of miRNA genes and their roles in key traits of poplar as stress resistance plant breeding and environment protection usage. Examination of sRNA expression in 2 poplar leaf samples in drought and normal growth conditions.

Comparison of gene expression in roots from Populus trichocarpa and Populus deltoides colonized with Laccaria bicolor

Project description: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 conditions (e.g. climate), but also on the genetic traits of the partners. To evaluate the impact of the genetic predisposition on the development and functioning of ectomycorrhizas, we compared the transcriptome of roots from Populus trichocarpa and Populus deltoides colonized with Laccaria bicolor. The Populus whole-genome expression array version 2.0 (S. DiFazio, A. Brunner, P. Dharmawardhana, and K. Munn, unpublished data) manufactured by NimbleGen Systems Limited (Madison, WI) contains in duplicates three independent, non-identical, 60-mer probes per whole gene model plus control probes and labeling controls. Included in the microarray are 65,965 probe sets corresponding to 55,970 gene models predicted on the P.trichocarpa genome sequence version 1.0 and 9,995 aspen cDNA sequences (Populus tremula, Populus tremuloides, and P. tremula x P. tremuloides). NimbleGen whole genome microarray analyses were performed in triplicate as per manufacturer's instructions. We carried out six hybridizations (NimbleGen) with samples derived from Populus trichocarpa and Populus deltoides mycorrhizal root tips. Three samples (biological replicates) originated from Populus trichocarpa (GSM648401, GSM648403, GSM648405) and three biological replicates from Populus deltoides (GSM648408, GSM648411, GSM648414). cDNA was synthesized using CLONTECH Super Smart cDNA Synthesis kit containing an amplification step on the cDNA level. All samples were labeled with Cy3.

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 250M-BM-5m ACC, 10nM JA or 500M-BM-5M 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 We performed 27 hybridizations (NimbleGen) with samples derived from Populus tremula x Populus alba clone 717-1B4 control roots, untreated mycorrhiza, SA-treated mycorrhiza, ACC-treated mycorrhiza and JA-treated mycorrhiza (3 biological replicates each) as well as Populus tremula x Populus tremuloides T89 control roots, mycorrhiza, 35S::PttACO1 mycorrhiza and 35S::Atetr1-1 mycorrhiza (3 biological replicates). All samples were labeled with Cy3.

Ptr-miR397a is a negative regulator of laccase genes affecting lignin content in Populus trichocarpa

Project description: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, 17 PtrLACs were down-regulated as analyzed by RNA-seq. Transgenic lines with severe reduction in the expression of these laccase genes resulted in an approximately 40% decrease in the total laccase activity. Overexpression of Ptr-MIR397a in these transgenic lines also reduced lignin content, whereas levels of all monolignol biosynthetic gene transcripts remained unchanged. A hierarchical genetic regulatory network (GRN) built by a bottom-up Graphic Gaussian Model algorithm provides additional support for a role of ptr-miR397a as a negative regulator of laccases for lignin biosynthesis. Full transcriptome based differential gene expression in the overexpressed transgenics and protein domain analyses implicate previously unidentified transcription factors and their targets in an extended hierarchical GRN including ptr-miR397a and laccases that coregulate lignin biosynthesis in wood formation. Ptr-miR397a, laccases and other regulatory components of this network may provide additional strategies for genetic manipulation of lignin content. Total twelve trees were used. Those include nine individual transgenic trees for overexpressing Ptr-miR397a, as nine biological replicates, and three wild-type trees.
