Project description:In the present study, the gene expression changes in four different tissues of root tips from maritime pine were analyzed. The roots were under two nutritional conditions (only watered or fertilised with 3 mM of ammonium) and harvested after 24 hours of the treatment.

Project description:The pinewood nematode, Bursaphelenchus xylophilus, the pine wilt disease's causal agent, is a migratory endoparasitic nematode skilled to feed on pine tissues and on fungi that colonize the trees. In order to study B. xylophilus secretomes under the stimulus of pine species with different susceptibility to disease, nematodes were exposed to aqueous pine extracts from Pinus pinaster (high susceptible host) and P. pinea (low susceptible host). Sequential windowed acquisition of all theoretical mass spectra (SWATH-MS) was used to determine relative changes in protein amounts between B. xylophilus secretions, and a total of 776 secreted proteins were quantified in both secretomes.

Project description:The main objective of the present work is the transcriptomic analysis of the interaction between nitrogen nutrition and CO2 levels in maritime pine. For this purpose, seedlings were fertilized with nitrate or ammonium and grown in two different CO2 levels: normal (400 ppm) and high (720ppm).

Project description:The significant morphological differences observed during embryo development in angiosperms and gymnosperms are expected to be the result of a differential control of gene expression. We used a loblolly pine (Pinus taeda) cDNA microarray to analyze global transcriptional changes along zygotic embryogenesis in maritime pine (Pinus pinaster). A time-course analysis of the data obtained from the five embryo developmental groups used in this study led to the identification of 4,645 genes whose expression varied along P. pinaster embryogenesis. These transcripts were clustered into six distinct expression profiles. The grouping of these profiles in early, mid-embryogenesis and embryo maturation, according to the developmental period where most of the sequences were up-regulated, evidenced that characteristic transcriptional changes are associated to each developmental period. The application of a cut-off value of 1.95-fold change led to the identification of 1,838 differentially expressed transcripts that were categorized by biological process. Metabolism, interaction with the environment, oxidation-reduction and transport were some of the most represented categories. During early embryogenesis genes putatively involved in phytohormone-mediated signaling were identified, whereas in middle stages the overrepresented genes could be associated with cotyledon formation and induction of somatic embryogenesis. Genes associated with the synthesis of storage products were up-regulated in the latest stages of pine embryo development. It was also during this developmental period that the largest number of sequences putatively encoding transcription factors was identified.

It was also during this developmental period that the largest number of sequences putatively encoding transcription factors was identified. Pine immature zygotic embryos were pooled into five different developmental groups according to the collection date (Day0; Day5; Day11; Day15 and Day25). A common reference design was used. Total RNA was extracted from each sample. Three extractions were prepared per sample (biological replicates). A defined ammount from each RNA sample was pooled to use as reference. Messenger RNA was amplified for both test samples and reference. These were hybridized together in two separate experiments (technical replicates). In total, 30 slides were analyzed.

Project description:Ammonium nutrition was studied at short times (24 hours) in roots from one month-old seedlings of maritime pine. Control seedlings were irrigated with 80 mL of water (C) and the experimental seedlings with 80 mL of 3 mM NH4Cl. Root samples were collected at 24 hours post-irrigation and immediately frozen in liquid N. This experiment was carried out three independent times.
