Project description:Plant-microbe interactions have been applied in the phytoremediation of pesticides to ensure food safety and reduce environmental health risks. However, the plant signaling molecules triggered by microbes to degrade pesticides remain unclear. Herein, we demonstrated that CS8-gfp, a growth-promoting strain, promoted degradation of two pesticides in rice plants. To better understand the the potential mechanisms, we provided the transcriptome of CS8-gfp inoculated/uninoculated rice using RNA sequencing (RNA-seq).

Project description:Carbon (C) and nitrogen (N) contents of grain-filling stage are keys item that determined the growth of rice, and also the quality of seed. Therefore, to elucidating the mechanism of C/N signaling in a seed is an important problem for crops whose seed is used as food like rice. The DNA microarray analysis with the rice seed which was performed the additional fertilizer at the time of heading, in order to clarify how C/N signal change of the rhizosphere in seed production stage affects a seed component on a gene expression level. Fertilization was supplied at the same time of plantation and performed middle fertilizing 37 days after germination. 400 mg of ammonium chloride (NH4 Cl) was supplied at the time of heading to the “ + NH4 Cl ” group. Rice seeds were selected from 6 plants for RNA extraction, and hybridization on Affymetrix microarrays. We sought to understand the change of gene expression by the additional fertilization.

Project description:The oil palm fruit abnormality, mantled, is a somaclonal variant arising from tissue culture that drastically reduces yield, and has largely halted efforts to clone elite hybrids for breeding and oil production. Widely regarded as epigenetic, mantling had defied explanation, and has become an icon of unsustainability in environmentally sensitive tropical plantation crops. We identified the MANTLED gene using Epigenome Wide Association analysis of genetically identical palms from multiple clonal lineages. Hypomethylation of a LINE retrotransposon related to rice Karma, found in the intron of the homeotic gene DEFICIENS, is common to all mantled clones and is correlated with alternative splicing and loss of small RNA. DNA methylation is regained in spontaneous revertants accounting for non-Medelian inheritance of the Good Karma and Bad Karma epialleles. Thus epigenetic regulation of transposable elements results in somaclonal variation and provides a means to cull mantled nursery palms before committing limiting plantation resources to clonal propagation. DNA methylation profiling was performed using the McrBC DNA methylation dependent fractionation and microarray hybridization method as described in Lippman, Z., Gendrel, A. V., Colot, V. & Martienssen, R. Profiling DNA methylation patterns using genomic tiling microarrays. Nat Methods 2, 219-224 (2005).

DNA methylation profiling was performed on 54 parthenocarpic mantled ramet, 43 normal ramet and 1 ortet adult leaf samples. For each sample, two independent fractionations of total genomic DNA and DNA methylation-depleted DNA were performed. Each total DNA/methylation-depleted DNA pair was differentially labeled and hydrized to a custon Nimblegen microarray in a dye-swapped design (4 array hybridizations per sample).

Project description:Parkinson’s Disease (PD) is a disease of the central nervous system that progressively affects the motor system. Epidemiological studies have provided evidence that exposure to agriculture-related occupations or agrichemicals elevate a person’s risk for PD. Here, we sought to examine the possible epigenetic changes associated with working on a plantation on Oahu, HI and/or exposure to organochlorines (OGC) in PD cases. We measured genome-wide DNA methylation using the Illumina Infinium HumanMethylation450K BeadChip array in matched peripheral blood and postmortem brain biospecimens in PD cases (n=20) assessed for years of plantation work and presence of organochlorines in brain tissue. The comparison of 10+ to 0 years of plantation work exposure detected 7 and 123 differentially methylated loci (DML) in brain and blood DNA, respectively (P<0.0001). The comparison of cases with 4+ to 0-2 detectable levels of OGC, identified 8 and 18 DML in brain and blood DNA, respectively (P <0.0001). Pathway analyses revealed links to key neurotoxic and neuropathologic pathways related to impaired immune and proinflammatory responses as well as impaired clearance of damaged proteins, as found in the predominantly glial cell population in these environmental exposure-related PD cases.

Project description:As virus diseases cannot be controlled by traditional plant protection methods the risk of their spread have to be minimized on vegetatively propagated plants, such as grapevine. Metagenomics approaches used for virus diagnostics, offer a unique opportunity to reveal the presence of all viral pathogens in the investigated plant, why their usage can reduce the risk of using infected material for a new plantation. Here we used a special field, deep sequencing of virus derived small RNAs, of this high throughput method for virus diagnostics and determined viromes of vineyards in Hungary. With NGS of virus derived small RNAs we could detect not only the viruses tested routinely, but also new ones, which have never been described in Hungary before. Virus presence didn’t correlated with the age of the plantation, moreover phylogenetic analysis of the identified virus isolates suggests that infections mostly caused by the usage of infected propagating material. Our results, validated by other molecular methods, highlighted further questions to be answered before these method can be introduced as a routine, reliable test for grapevine virus diagnostics.

Project description:We combined in vitro tests to fully assess the capacity of pesticides to act as thyroid hormone disruptors (THD). Pesticides which were active in these tests were selected for a transcriptome analysis of neural cells. We took advantage of this technique to decipher what were the transcriptomic effects of these chemical in vitro. We also compared the expression of thyroid hormone responsive genes in presence or absence of the pesticides to determine if the transcriptomic changes could impact thyroid hormone receptor signaling. Although some pesticides elicit a cellular response, which sometimes interferes with thyroid hormone signaling, we found no evidence that they can act as TRα1 agonists or antagonists. We conclude that their neurodevelopmental toxicity in mammals is not explained by an alteration of the neural cell response to thyroid hormone.
