Project description:Fungal entomopathogens like Beauveria bassiana (Bals.) Vuill. (Ascomycota: Hypocreales) are known as antagonist of insects with multiple functional and ecological roles and have attracted increased attention as biocontrol agents in integrated pest management programs. A microarray analysis was performed to work out fundamental aspects of genes involved in the interaction between grapevine and the endophytic fungus B. bassiana. The results indicate an up-regulation of diverse defense-related genes in grapevine as a response to a treatment with B. bassiana
Project description:Genome wide DNA methylation profiling of OSCC tissue samples, oral lichen planus tissue samples and normal controls. The Illumina Infinium 450k Human DNA methylation Beadchip was used to obtain DNA methylation profiles across approximately 480,000 CpGs. Samples included 15 OSCC, 8 lichen planus and 18 control samples.
Project description:Comparing gene expression in Oral and genital lichen planus with normal oral and genital epithelium trying to idenitfy differently expressed genes in lichen planus compared to normal epithelium Total RNA obtained from oral and genital lichen planus epithelium compared with normal oral and genital epithelium
Project description:The endophytic fungi of certain grasses and herbaceous plants provide anti-herbivore defense compounds, thus living in mutualistic interaction with their hosts. Still, there is little information on such cooperation for tree-associated endophytes. We investigate the influence of the endophytic fungus Cladosporium cladosporioides on the chemical defenses of black poplar Populus nigra trees and the consequences on feeding preference, fitness of herbivorous insects, and insect community assembly. Strikingly, endophyte colonization increases both constitutive- and induced poplar defenses. Generalist Lymantria dispar larvae prefer and perform better on uninfected poplars due to the higher concentrations of salicinoids and fungal alkaloid stachydrine in endophyte-infected leaves. Under field conditions, the endophytic fungus shapes insect community assembly in young black poplar trees. Our results show that endophytic fungi can play a significant role in defending trees against herbivorous insects and structuring insect communities.
