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.

A common graft formation pathway in Norway spruce and Arabidopsis thaliana identifies the PAT gene family as conserved regulators of tissue attachment and wound healing [RNAseq: Hornome-Treatment-samples]

(Submitter supplied) The widespread use of plant grafting has enabled different plants to join and combine their best properties to improve stress tolerance, growth and yields. Grafting is commonly performed between closely related eudicots or gymnosperms where mechanisms permit tissue fusion yet limit success as plants become unrelated. To investigate these aspects, we developed a micrografting method using young conifer tree seedlings that enabled divergent conifer members to successfully graft. more...

Analysis of gene-targeted DNA methylation patterns through the annual cycle in clonal epitypes of Norway spruce

(Submitter supplied) Main goal of the study is to distinguish stable DNA methylation differences from dynamic changes during the annual cycle in different epitypes. We examined whether the extant epigenetic marks created during embryogenesis under EpI-temperature conditions are maintained in the resulting epitype trees. We used unique well-defined clonal epitypes with a stable epigenetic memory of the temperature sum experienced during embryogenesis impacting bud phenology. more...

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...

High-throughput sequencing of small RNAs in Picea abies

(Submitter supplied) Small RNAs (21-24 nt) are pivotal regulators of gene expression that guide both transcriptional and post-transcriptional silencing mechanisms in diverse eukaryotes, including most if not all plants. MicroRNAs (miRNAs) and short interfering RNAs (siRNAs) are the two major types, both of which have a demonstrated and important role in plant development, stress responses and pathogen resistance. In this work, we used a deep sequencing approach (Sequencing-By-Synthesis, or SBS) to develop sequence resources of small RNAs from Picea abies tissues (including needles, immature cones and lateral bud meristem). more...

Evolution of Gene Expression in Spruce (Genus Picea)

(Submitter supplied) Diversification of defense-related compounds is a plant defense mechanism against the diverse array of natural enemies in the course of evolution, and is known to involve various sources of tissue. Here a large-scale survey of gene expression is conducted from three different sources of tissue; needles, phloem with the attached bark, and xylem, with an emphasis on the expression of the secondary metabolites of the core phenylpropanoid pathway and derivative pathways, taken together as phenolic defense-related compounds. more...

Norway Spruce Cultured Cells Chitosan & C.polonica Stress

(Submitter supplied) Conifer-specific responses to elicitation with the chemical elicitor chitosan have been investigated using a transcriptome analysis in Norway spruce using a cell suspension culture system that has been previously described (Phillips, Walter et al. 2007). This study has demonstrated that the early events following chitosan elicitation include calcium mediated signaling and an oxidative response that have not previously been described in intact trees. more...

Microarray assay of the genetic response of Picea abies to Heterobasidion annosum infection (Loops 1 and 2)

(Submitter supplied) The hypothesis of the experiment is that infected trees of high resistance express a wider variety of resistance genes than infected trees of low resistance, and that the level of expression of these resistance genes differs between infected and healthy branches. Also, some genes highly expressed in the infected state not expressed in the healthy state may be in response to the wounding rather than the actual infection. more...
