Project description:In this work, we have used deep sequencing to study the viral small RNA (vsiRNA) populations from different mycoviruses infecting field isolates of Botrytis spp. The mycoviruses under study belong to different genera and species and have different type of genome (dsRNA, (+)ssRNA, and (-)ssRNA). In general, vsiRNAs derived from mycoviruses are mostly of 21, 20 and 22 nucleotides in length, possess sense or antisense orientation either in a similar ratio or with a predominance of sense polarity depending on the virus species, have predominantly U at their 5' end, and are unevenly distributed along the viral genome showing conspicuous hotspots of vsiRNA accumulation. These characteristics reveal striking concomitances with vsiRNAs produced by plant viruses suggesting similar pathways of viral targeting in plants and fungi
Project description:Phytophthora cactorum hosts mycoviruses, whose effects on the host have not been studied. In the present study, two viruses of the order Bunyavirales significantly reduced hyphal growth in the host isolate, and the virus colonization also increased the elicitin production as detected by RNA-seq and proteomic analyses.
Project description:The white button mushroom Agaricus bisporus is the most widely produced edible fungus with a great economical value. Its commercial cultivation process is often performed on wheat straw and animal manure based compost that mainly contains lignocellulosic material as a source of carbon and nutrients for the mushroom production. As a large portion of compost carbohydrates are left unused in the current mushroom cultivation process, the aim of this work was to study wild-type A. bisporus strains for their potential to convert the components that are poorly utilized by the commercial strain A15. Growth profiling suggested different abilities for several A. bisporus strains to use plant biomass derived polysaccharides, as well as to transport and metabolize the corresponding monomeric sugars. Six wild-type isolates with diverse growth profiles were compared for mushroom production to A15 strain in semi-commercial cultivation conditions. Transcriptome and proteome analyses of the three most interesting wild-type strains and A15 indicated that the unrelated A. bisporus strains degrade and convert plant biomass polymers in a highly similar manner. This was also supported by the chemical content of the compost during the mushroom production process. Our study therefore reveals a highly conserved physiology for unrelated strains of this species during growth in compost.
Project description:Mushroom bodies (MBs) are the centers for olfactory associative learning and elementary cognitive functions in the Drosophila brain. To get insights of the repertoire of MB genes that control initiation and maintenance of neural differentiation as well as the repertoire of neural factors that may have functions in the synaptic plasticity of MB neurons during learning and memory, we compared the transcript profiles between wild type and MB-ablated brains using a Drosophila whole-genome microarray. Newly hatched larvae were briefly administered with a DNA-synthesis inhibitor, hydroxyurea, and raised to adults, from which total brain RNA was analyzed. Keywords: Chemical Ablation of Mushroom bodies from Drosophila brain

Project description:We investigated the effect of the absence of the eisosome on the overall yeast transcriptome by gene expression profiling analysis. We used data obtained from RNA-seq (polyA enrichment of total RNA isolates) of 3 different strains, specifically wild type (BY4742), a strain missing PIL1 gene that forms eisosome remanants instead of eisosome and our newly described seg1Δnce102Δpil1Δ strain, which forms neither eisosomes, nor eisosome remnants, even in the response to stress.

Project description:Hypsizygus marmoreus is one of the most popular industrialized cultivation mushrooms in East Asia, including China, Korea and Japan. It draws our attention due to its desirable, mildly sweet nutty flavor, unique texture and medicinal properties. As a result, the number of H. marmoreus cultivation factories increased gradually in different regions of the world, especially in China. H. marmoreus is the third wildly cultivated industrialized cultivated mushroom in China now. However, its development process is still not very clear. In this study, we use proteomics analysis to investigate the mechanism involved in development of Hypsizygus marmoreus.
