Activation of defense pathways in Scots pine bark after feeding by Pine Weevil (Hylobius abietis)

ABSTRACT: Coniferous trees use the oleoresin, a mixture of non-volatile non-volatile diterpene acids and a large (20-50%) volatile fraction of mono- and sesquiterpenes, as a defence tool against damaging herbivores and pathogens. Volatilization of monoterpenes increases viscosity of oleoresin and finally leading to polymerization of resin and a formation of protective solid plug. Resin storing conifers form an important source of volatile organic compounds (VOCs) mainly dominated by volatile monoterpenes. In the atmosphere, conifer VOCs react with ozone and OH and nitrous oxide radicals forming secondary organic compounds. This project seeks a better understanding of the genetic control of conifer defences and the role of monoterpenoid compounds under biotic stresses. Two separate samples were analysed (control-unchallenged and treatment-infected with the insect). There were a total of 3 biological replicates for the control samples and another set of three biological replicates for the treatment samples.

Physiological response and proteomics analysis of Castanopsis fissa under drought stress

Project description:Castanopsis fissa is an evergreen broad-leaved species of the cone genus Castanopsis in the family Fagaceae, which is widely distributed and is an excellent native species in Guangdong Province of China. This species has a well-developed root system, excellent soil-fixing power, and better soil and water conservation ability and has the characteristics of barren tolerance, strong sprouting power, abundant and easily decomposed dead leaves, etc. Therefore, C. fissa is not only a pioneer species for postdestruction sprouting forests but also a highly potential ecological public welfare forest tree species. Moreover, due to its beautiful shape, wide canopy and various colors, it has become an ideal tree for landscaping and ornamental purposes. However, there is a basic gap in knowledge in the reports on the drought resistance or drought tolerance genes of C. fissa. Based on the above details, in this study, 2-year-old C. fissa seedlings were used as the study material to investigate the physiological response under drought stress by a potted drought experiment, and we also compared and analyzed the differentially expressed proteins (DEPs) under different periods of drought stress by TMT quantitative labeling protein to prepare a preliminary study on the physiological response and proteomic mechanism of C. fissa adaptation to drought stress.

Scots pine (Pinus sylvestris) differentially interacts with Cenococcum geophilum and other simultaneously inoculated mycorrhizal (ECM) fungi

Project description:To identify specific gene networks induced in host roots by C. geophilum, we inoculated seedlings of Scots pine simultaneously with C. geophilum and either Suillus granulatus or Rhizopogon roseolus, two common ECM fungi associated to pines. We then measured the differential expression of Scots pine genes in the respective mycorrhizas using oligoarrays. We performed 14 hybridizations (NimbleGen) with samples derived from Pinus sylvestris mycorrhiza with Cenococcum geophilum, Rhizopogon roseolus or Suillus granulatus (3 biological replicates each), as well as from non-mycorrhizal control roots (two replicates). Only the Pinus-derived sequences from the array were considered for this analysis. All samples were labeled with Cy3.

Transcriptional profiling of the rust fungus Cronartium quercuum f. sp. fusiforme (Cqf) during vegetative growth on 2 different hosts.

Project description:The purpose of this study was to make a single comparison between Cqf genes expressed during the vegetative stages of infection on the telial host (oak leaf) versus the aecial host (pine stem). A large proportion of genes were expressed in both hosts and significantly differentially expressed genes were enriched for candidate fungal effectors (small secreted proteins). These results suggest that the Cqf rust fungus uses a largely common set of genes to create two very different infection phenotypes. This study was based on hybridizations to custom microarrays containing features representing 8692 gene models from a Cqf genome sequencing project midpoint assembly. Two Agilent 4 X 44K microarray slides were populated with 60-mer probes (1 to 5 per transcript), designed using AgilentM-bM-^@M-^Ys web-based eArray software. Labeled target cRNA (complementary RNA) was generated using AgilentM-bM-^@M-^Ys Low Input Quick Amp Labeling Kit, such that oak and pine samples were labeled with either cy3 or cy5 an equal number of times across the experiment. Each microarray was hybridized with labeled cRNA target derived from a single oak sample and labeled cRNA target derived from a single pine sample. There were a total of eight oak sample replications and eight pine sample replications. Target hybridization and scanning were performed by the University of FloridaM-bM-^@M-^Ys Interdisciplinary Center for Biotechnology Research using standard procedures and an Agilent G250B Scanner.

Effect of biotin deficiency on gene expression in Aravbidopsis leaves

Project description:In addition to its essential metabolic functions biotin is suggested a critical role in regulating gene expression. The first committed enzyme in biotin biosynthesis in Arabidopsis, 7-keto-8-aminopelargonic acid synthase is encoded by At5g04620 (BIO4). We isolated a novel T-DNA insertion mutant of BIO4 (bio4-1) showing a spontaneous cell death phenotype that could be rescued both by exogenous biotin and genetic complementation. The bio4-1 plants exhibited massive accumulation of hydrogen peroxide. The T-DNA insertion in the bio4-1 mutant contains a Methionine Sulfoxide Reductase B9 (AT4G21850) under a constitutive 35S CaMV promoter. To dissect the specific effects of biotin defiency on gene expression on a genome wide scale, we compared expression of wt Col-0 leaves with bio4-1 mutants and bio4-1 mutants complemented with D-biotin. Expression in leaves of Col-0 wt, bio4-1 mutants with a T-DNA insertion in the 5`-UTR of BIO4, and bio4-1 mutants complemented with watering with 200ÂµM D-biotin.

Transcription profiling of SET-2 deletion and wild type yeast on sense and anti-sense arrays

Project description:The presence of Set2-mediated methylation of H3K36 (K36me) correlates with transcription frequency throughout the yeast genome. K36me targets the Rpd3S complex to deacetylate transcribed regions and suppress cryptic transcription initiation at certain genes. Here, using a genome-wide approach, we report that the Set2-Rpd3S pathway is generally required for controlling acetylation at coding regions. When using acetylation as a functional read-out for this pathway, we discovered that longer genes and, surprisingly, genes transcribed at lower frequency exhibit a stronger dependency. Moreover, a systematic screen using high resolution tiling microarrays allowed us to identify a group of genes that rely on Set2-Rpd3S to suppress spurious transcripts. Interestingly, most of these genes are within the group that depend the same pathway to maintain a hypo-acetylated state at coding regions. These data highlight the importance of using the functional readout of histone codes to define the roles of specific pathways.
