Microarray assay of the genetic response of Picea abies to Heterobasidion annosum infection - Loop2

ABSTRACT: 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. By comparing these expressions to that of wounded, uninfected branches, this could also be clarified. Three different Picea abies clones, of increasing resistance to fungal attack, have been infected. For all clones, three rametes have been infected with Heterobasidion of 1 month, by means of cutting the cambium and inoculating a piece of fungus growing in agar in the wound. For the low and medium resistant clone, a fourth ramete has been cut and inoculated with agar not containing any fungal material.

The transcriptome of the arbuscular mycorrhizal fungus Glomus intraradices

Project description:The virtual transcriptome of G. intraradices (based on >430,000 reads) served as the basis for the design of an EST expresson array and for a number of analyses of gene expression in germinating spores, extraradical mycelium (ERM) and symbiotic root tissues. The G. intraradices EST expression array (4 x 72K) manufactured by Roche NimbleGen Systems Limited (Madison, WI) (http://www.nimblegen.com/products/exp/index.html) contained three independent, non identical, 60-mer probes per sequence. Included in the oligoarray were 22,402 G. intraradices sequences, 5785 random 60-mer control probes and labeling controls. We performed 12 hybridisations with samples from germinating spores (three biological replicates), extraradical mycelium (three biological replicates), symbiotic root tissues from Medicago (three biological replicates) and rice (1 replicate) as well as from microdissected arbuscule-colonized cortical cells of Medicago and rice (1 replicate each).

Sepula lacrymans interacting with tree roots

Project description:This study characterizes the transcriptomic alterations of Serpula lacrymans in contact with tree roots compared to the transcriptome of free-living mycelium. We performed 6 hybridizations (NimbleGen) with samples derived from Picea sylvestris root tips inoculated with Serpula lacrymans (three biological replicates). These samples were compared to free-living mycelium from Serpula lacrymans (three biological replicates). All samples were labeled with Cy3.

Lotus Flower-Bud Transcriptome or Gene expression

Project description:Flower-lotus with many attractive floral characteristics has been studied and discussed the most. These characteristics are used as the standards of the classification in most cases, and always attracted the attention of lotus breeders on improvement program because of associating with ornamental and economic values of lotus. However, molecular mechanisms underlying the formation of these attractive floral features still remain largely unknown. Transcriptome sequencing technique has been established as an efficient approach for gene discovery and expression pattern identification. For some plants, a lot of important genes involved in plant critical metabolisms have been successfully identified by this technique. In the study, mass sequence data obtained from the deep sequencing of a mixed flower-bud cDNA pool from three individuals of N. nucifera provide a platform to comprehensively understand the processes of flower formation and development at the molecular level, and will greatly facilitate the genetic improvement of ornamental characteristics and the directive molecular breeding for lotus in the future. A mixed cDNA pool from young flower-buds (35-40mm in length) of three accessions of N. nucifera were used for deep sequencing using 454 GS-FLX Titanium.

Mechanisms of interaction between ectomycorrhizal fungi and the mycorrhiza helper bacterium Pseudomonas fluorescens BBc6R8

Project description:Mycorrhiza helper bacteria (MHB) promote the formation of ectomycorrhizae between tree roots and ectomycorrhizal fungi. Despite the high relevance of MHB for forestry and for sustainable tree production in tree nurseries, little is known about the properties of the bacteria that contribute to their helper abilities. The MHB strain Pseudomonas fluorescens BBc6R8 is used as a model to study the mechanisms of the helper effect. We took advantage of new technologies to obtain, for the first time, the whole genome sequence of an MHB. Analyses reveal an important plasticity of the genome with numerous functions acquired by horizontal gene tranfer. Genome mining was combined with transcriptomic and mutagenesis approaches to reveal molecular determinants of the helper effect. The data suggest that the production of helper molecules is likely to be constitutive in vitro. The helper effect appears to be pleiotropic and to rely, for a substantial part, on trophic interactions. Despite its helper abilities, the bacterium is also able in specific conditions to outcompete ectomycorrhizal fungi and inhibit their growth. We conclude that the helper bacterium possess a broad range of properties whose expression depending on the biotic and abiotic conditions can result in either a beneficial, neutral or antagonistic interaction between the plant, the ectomycorrhizal fungus and the bacterium. The study was performed along a kinetic with three sampling times: before contact between the bacterial colonies and the fungus (14 days after inoculation), at the time of contact (16 days after inoculation) and after an extended period of contact (21 days). For each time, three independent replicates were performed. A control treatment without the fungus was performed in triplicate and sampled at 14 days.

Histone Demethylase-Assisted Somatic Cell Nuclear Transfer Facilitates Derivation of Human Pluripotent Stem Cells

Project description:The extremely low efficiency of human embryonic stem cell (hESC) derivation using somatic cell nuclear transfer (SCNT) limits potential application. Blastocyst formation from human SCNT embryos occurs at a low rate and with only some oocyte donors. We previously showed in mice that reduction of histone H3 lysine 9 trimethylation (H3K9me3) through ectopic expression of the H3K9me3 demethylase Kdm4d greatly improves SCNT embryo development. Here we show that overexpression of a related H3K9me3 demethylase KDM4A improves human SCNT, and that, as in mice, H3K9me3 in the human somatic cell genome is an SCNT reprogramming barrier. Overexpression of KDM4A significantly improves the blastocyst formation rate in human SCNT embryos by facilitating transcriptional reprogramming, allowing derivation of NTESCs from all oocyte donors tested using adult AMD patient somatic nuclei donors. This conserved mechanistic insight has potential applications for improving SCNT in a variety of contexts, including regenerative medicine. Here we perform RNA-seq based transcriptome profiling in human Donor (fibroblast cells), in vitro fertilized embryos at 8-cell stages (IVF_8Cell), somatic cell nuclear transfer embryos at 8-cell stages (SCNT_8Cell), SCNT assisted by KDM4A 8-cell embryos (SCNT_KDM4A_8Cell). Besides, we also perform RNA-seq in Control human ES cells (CTR_hES) and SCNT assisted by KDM4A derived human ES cells (NTK) with duplicates.Â
