Project description:250 adult T. urticae females from the London strain (grown on acyanogenic P. vulgaris cv. Prelude bean plants) were transferred to cyanogenic P. lunatus cv. 8078 bean plants. Thirty-five generations after the host transfer, total RNA was extracted from mites growing on both bean species (London and London-CYANO strain) and used in in a genome-wide gene expression microarray (Sureprint G3 microarray, Agilent) experiment to assess significantly differentially expressed genes (FC ≥ 2 and FDR-corrected p-value < 0.05) between mites grown on P. vulgaris (cv. Prelude) bean plants (London strain) and mites grown for 35 generations on P. lunatus (cv. 8078) bean plants (London-CYANO strain).

Project description:Many genes involve in pathogenicity and virulence are induced only in plant or in the presence of host components. Bean leaf extract was obtained from healthy bean leaves. In this work we investigated the effect of bean leaf extract on the transcriptomic profile of the bacterium, when grown at low temperature in minimal medium with or without extract from healthy bean leaves.

Project description:The immunomodulatory effect of mung bean is mainly attributed to antioxidant properties of flavonoids; however, the precise machinery for biological effect on animal cells remains uncertain. The objective of this study was to understand the physiological change produced by mung bean consumption.

Project description:A wide range of environmental stresses lead to an elevated production of reactive oxygen species (ROS) in plant cells thus resulting in oxidative stress. The biological nitrogen fixation in the legume - Rhizobium symbiosis is at high risk of damage from oxidative stress. Common bean (Phaseolus vulgaris) active nodules exposed to the herbicide Paraquat (1,1 '-Dimethyl-4, 4'-bipyridinium dichloride hydrate) that generates ROS accumulation, showed a reduced nitrogenase activity and ureide content. We analyzed the global gene response of stressed nodules using the Bean CombiMatrix Custom Array 90K, that includes probes from some 30,000 expressed sequence tags (EST). A total of 4,280 ESTs were differentially expressed in oxidative stressed bean nodules; of these 2,218 were repressed. These genes were grouped in 44 different biological processes as defined by Gene Onthology. Analysis with the PathExpress bioinformatic tool, adapted for bean, identified five significantly repressed metabolic path

Project description:Grapevine red blotch is a recently identified viral disease that was first recognized in the Napa Valley of California. Infected plants showed foliar symptoms similar to leafroll, another grapevine viral disease, on vines testing negative for known grapevine leafroll-associated virus. Later, the Grapevine red blotch virus (GRBV) was independently discovered in the US states of California and New York and was demonstrated to be the causal agent of red blotch disease. Due to its wide occurrence in the US, vector transmission and impacts on grape industry, this virus has the potential to cause serious economic losses. Despite numerous attempts, it was not possible to isolate or visualize viral particles from GRBV infected plants. Consequently, this has hampered the development of a serological assay that would facilitate GRBV detection in grapevine. We therefore decided to explore mass spectrometry approaches in order to quantify GRBV in infected plants and to identify potential biomarkers for viral infection. We present for the first time the physical detection on the protein level of the two GRBV genes V1 (coat protein) and V2 in grapevine tissue lysates. The GRBV coat protein load in leaf petioles was determined to be in the range of 100 to 900 million copies per milligram wet weight by using three heavy isotope labeled reference peptides as internal standards. The V1 copy number per unit wet tissue weight in leaves appeared to be about six times lower, and about 200-times lower in terms of protein concentration in the extractable protein mass than in petioles. We found a consistent upregulation of several enzymes involved in flavonoid biosynthesis in leaf and petiole extracts of GRBV-infected plants by label-free shotgun proteomics, indicating the activation of a defense mechanism against GRBV, a plant response already described for grapevine leafroll associated virus infection on the transcriptome level. Last but not least, we identified some other microorganisms belonging to the grapevine leaf microbiota, two bacterial species (Novosphingobium sp. Rr 2-17 and Methylobacterium) and one virus, Grapevine rupestris stem pitting associated virus.

Project description:TIFY is a large plant-specific transcription factor gene family. A subgroup of TIFY genes named JAZ (Jasmonate-ZIM domain) has been identified as repressors of jasmonate (JA)-regulated transcription in Arabidopsis and other plants. JA signaling is involved in many aspects of plant growth/development and in the defense responses to biotic and abiotic stresses. Here we identified the TIFY genes (designated as PvTIFY) from the legume common bean (Phaseolus vulgaris) and functionally characterized PvTIFY10C as a transcriptional regulator. Twenty-three genes from the PvTIFY gene family were identified through whole genome sequence analysis. Most of these were induced upon methyl-JA elicitation. We selected PvTIFY10C as a representative JA-responsive PvTIFY gene for further functional analysis. Transcriptome analysis via microarray hybridization using the designed Bean Custom Array 90K was performed in transgenic roots of composite plants with modulated -RNAi-silencing or over-expression- PvTIFY10C gene expression. Data were interpreted using Mapman adapted to common bean. Microarray differential gene expression data were validated by real-time qRT-PCR expression analysis. Comparative global gene expression analysis revealed opposite regulatory changes in processes such as RNA and protein regulation, stress response and metabolism in silenced vs. over-expressing roots. These data point to transcript reprogramming -mainly repression- orchestrated by PvTIFY10C. In addition we found that several PvTIFY genes as well as genes from the JA biosynthetic pathway responded to P-deficiency. Relevant P-responsive genes that participate in carbon metabolic pathways, cell wall synthesis, lipid metabolism, transport, DNA, RNA and protein regulation, signaling, were oppositely-regulated in control vs. PvTIFY10C silenced roots. These data indicate that PvTIFY10C regulates, directly or indirectly, gene expression of some P-responsive genes something that could be mediated by JA-signaling.
