Fine root gene expression of Norway spruce cuttings

(Submitter supplied) We investigated root associated fungi in young Norway spruce (Picea abies) cuttings rooted from slow- and fast-growing trees showing variable growth rate in long-term field experiments and compared their roots’ gene expression patterns five and 18 months after adventitious root initiation. Gene expression patterns of adventitious roots could not be systematically linked with the growth phenotype at the initiation of root formation, and thus fundamental differences in the receptiveness of fungal symbionts could not be assumed.

Transcript profiling reveals a molecular signature that distinguishes early versus late time to bud set phenotypes in a white spruce full-sib family.

(Submitter supplied) It is crucial for north temperate tree species like white spruce to control timing of growth cessation and bud set in order to survive winter conditions. While much work has examined both endogenous and exogenous mechanisms influencing this transition within angiosperms, the mechanisms underlying this transition in conifers; including photoperiod perception, growth cessation and development of endodormancy, have been less well-characterized. more...

A natural expression variant reveals a novel mechanism of insect resistance in boreal forest trees.

(Submitter supplied) We report the discovery of a beta-glucosidase gene (Pgβglu-1) whose expression underpins natural resistance to a major forest pest, the spruce budworm (SBW) in white spruce (Picea glauca (Voss.) Moench). We performed a microarray experiment to compare resistant (R) and non-resistant (N-R) trees. Pgβglu-1 transcripts levels uniquely were up to 1000 times higher in phenotypically resistant trees and correlated with accumulation of acetophenones compounds that reduce SBW development. more...

Differential expression of miRNAs in Brassica napus root following infection with Plasmodiophora brassicae

(Submitter supplied) Canola (oilseed rape, Brassica napus L.), is susceptible to infection by the biotrophic protist Plasmodiophora brassicae, the causal agent of clubroot. To understand the roles of microRNAs (miRNAs) during the post-transcriptional regulation of disease initiation and progression, we have characterized the changes in miRNA expression profiles in canola roots during clubroot disease development and have compared these to uninfected roots. more...

Direct measurement of heritable gene expression within single individuals from wild populations.

(Submitter supplied) Heritable variation in gene expression has been largely studied in model organisms by taking advantage of pure and inbred lines. Comparative studies on organisms with contrasting evolutionary history, population size and genome architecture have been hindered by practical considerations, as many of these species are poorly suited for breeding. We have developed a method for determining expression variation in an undomesticated tree species by directly measuring the segregation of gene expression in the haploid meiotic products of a single diploid individual. more...

Evaluation of differential expression in the vascular transcriptome among Picea species

(Submitter supplied) The goal of this experiment is to assess tissue preferential transcript accumulation and fold difference between two tissues that support secondary vascular growth in three spruces: Picea glauca, Picea sitchensis and Picea mariana. Tissues compared are secondary xylem (wood forming tissue located on the internal side of the cambial meristem) and phelloderm (composite sample of the phloem and phelloderm tissues located on the outer side of the cambial meristem).

PiceaGenExpress database of transcription profiles

(Submitter supplied) A small database of transcription profiles called PgGenExpress was developed from over 150 hybridizations spanning eight major tissue types. In total, transcripts were detected for 92% of the genes on the microarray, in at least one tissue. Non-annotated genes were predominantly expressed at low levels in fewer tissues than genes of known or predicted function. Diversity of expression within gene families may be rapidly assessed from PgGenExpress. more...

Novel genes in Sitka spruce associated with wood density identified from global transcriptomic analysis

(Submitter supplied) The current study uses a transcriptomic approach to identify genes associated with differences in wood density, that are likely to be of value as candidate genes in Sitka breeding programmes for improved wood density. Following extensive wood density analysis from a Sitka spruce (Picea sitchensis (Bong) Carr.) field grown clonal trial, three detailed microarray studies were conducted to compare the transcriptome of cambial tissue from contrasting clonal lines with high and low wood density. more...

SitkaSpruce_FB3-425_Bark_PissodesStrobi_Herbivory

(Submitter supplied) Based on the generation of ESTs, we developed a spruce cDNA microarray composed of 21,843 cDNA elements selected from 12 cDNA libraries representing developmental stages of xylem, phloem, bark and roots, as well as elicitor-treated bark. Clones on the array were selected from a CAP3 assembly of 50,770 hq 3’ ESTs, and were carefully chosen to represent a minimally redundant gene set. Using this array we examined global changes in the transcriptome of Sitka spruce attacked for two days by stem-boring white pine weevils. more...

Global monitoring of autumn gene expression within and among populations of Sitka spruce

(Submitter supplied) Cold acclimation in conifers is a complex process, the timing and extent of which reflects local adaptation and varies widely along latitudinal gradients for many temperate and boreal tree species. In spite of their ecological and economic importance, little is known about the global changes in gene expression that accompany autumn cold acclimation in conifers. Using three populations of Sitka spruce (Picea sitchensis) spanning the species range, and a Picea cDNA microarray with 21,840 unique elements, we monitored within and among-population gene expression during the fall. more...

SitkaSpruce_FB3-425_Bark_UntreatedControl_SelfHybridization

(Submitter supplied) As part of a larger conifer genomics project, we developed a new 21.8K cDNA microarray containing 21,843 spotted ESTs from spruce (Picea spp.). To evaluate the performance of the array we conducted four technical replicate self-self hybridizations using untreated control bark RNA pooled from four biological replicates. The objectives were to determine: 1) the linear dynamic range of expression detection of the array; 2) the level of non-specific hybridization to negative control elements on the array; and 3) the overall technical reproducibility of the array. more...

Arborea spruce 32K

(Submitter supplied) The sequences included in the microarray were selected on the basis of reproducible sequence quality form all of the ESTs and FL-cDNA described for P. glauca in Rigault et al. (2011) and P. sitchensis in Ralph et al. (2008) (Table 1A). To obtain a robust probe set, we selected sequences that were either detected in the two species, verified with two technologies (Sanger and 454) or were derived from a FL-cDNA (Table 1A). more...
