Project description:We report here an update of the Botrytis cinerea strains B05.10 and T4 genomes, as well as an automated preliminary gene structure annotation. High-coverage de novo assemblies and reference-based alignments led to a correction of wrong base calls, elimination of sequence gaps, and improved joining of contigs. The new assemblies have substantially lower numbers of scaffolds and a concomitant increase in the N(50).The list of protein-coding genes was generated using the evidence-driven gene predictor Augustus, with expressed sequence tag evidence and RNA-Seq data as input.
Project description:Comparison of Botrytis cinerea wild-type B.05.10 and T4 strains using label-free nUPLC-MSE and 2-DE approaches. B. cinerea strain mycelium were grown in synthetic minimal medium-modified Czapeck-Dox. Protein extracts were obtained from pulverized mycelium using TCA-phenol method. Acquired spectra were internally calibrated with peptides from trypsin 180 autolysis (M+H+=842.509,M+H+=2211.104) with an m/z precision of ±20 ppm. A combined search (PMF and MS/MS) was performed with GPS ExplorerTM software v3.5 (Applied Biosystems) over non-redundant NCBI databases using the MASCOT search engine. The database search utilized the following parameters: taxonomy restrictions to Fungi (06.17.2011), one missed cleavage sites, 100 ppm mass tolerance in MS and 0.5 Da for MS/MS data, cysteine carbamidomethylation as a fixed modification, and methionine oxidation as a variable modification. The confidence in the peptide mass fingerprinting matches (p<0.05) was based on the MOWSE score.
Project description:T4 and T5 neurons are components of the neuronal circuit for motion vision in flies. To identify genes involved in neuronal computation of T4 and T5 neurons, we perfomed transcriptome analysis. Nuclei of T4 and T5 neurons were immunoprecipitated, total RNA was harvested and used for mRNA-seq with Illumina technology. In two biological replicates, we mapped 154 and 119 million reads to D. melanogaster genome. mRNA-seq provided information about expression levels of 17,468 annotated transcripts in the T4 and T5 neurons.
