Project description:Chaetomium globosum is a model of conditional pathogens abundant on a wide variety of substrates in soil, water, and atmosphere environments. Homothallic C. globosum produces hairy perithecia bearing meiotic ascospores that are resistant to harsh conditions for dispersal, and asexual reproduction of conidia has never been observed. RNAs were samples from nine distinct morphological stages during the nearly synchronic perithecial development for C. globosum. Unlike the heterothallic Neurospora crassa, the mating type gene mat a-1 showed comparatively lower expression changes but highly coordinate with expression regulation of mat A-1 in C. globosum. Key regulators, including orthologs of N. crassa sub-1, sub-1 dependent gene NCU00309, and asl-1, in the initiation of sexual development in response to light stimuli, showed similar regulation dynamics between C. globosum and N. crassa. Knockout phenotyping directed by the comparative analysis of transcriptomics between C. globosum and its’ closely related Neurospora crassa also suggested some genes that are critical for perithecial development. Among 24 secondary metabolism clusters composed more than 3 genes in C. globosum, 11 showed highly coordinated expression across the perithecial development, and dramatically up-regulation was recorded for all 12 genes in the cochliodones biosynthesis cluster. Up-regulation of chaetoglocin and aureonitol biosynthesis clusters was found to be associated with disturbance in early sexual development and with ascospore maturation. Similar to pathogenic Fusarium graminearum, C. globosum showed coordinately up-regulated expression of homologs of histidine kinases in hyperosmotic response pathways, consist with their ecology adapting to high humidity.

Project description:The thermophilic filamentous fungi Myceliophthora thermophila (Sporotrichum thermophile) and Thielavia terrestris are proficient decomposers of cellulose, suggesting that they will be a rich source of thermostable industrial enzymes for lignocellulose degradation. To identify the genes and proteins involved in this process, we explored the transcriptomes of M. thermophila and T. terrestris growing at 45 ºC on either glucose, alfalfa, or barley straw by short-read sequencing of extracted mRNA. To better understand the adaptations that allow these fungi to grow at elevated temperatures, we compared their transcriptomes when growing at 34C to their transcritomes at 45C, and also to the transcriptome of the related fungus Chaetomium globosum, which does not grow at 45C.

RNA was extracted from cultures in early growth stage growing with glucose, alfalfa, or barley straw as carbon source at 34C or 45C (M. thermophila and T. terrestris); duplicate cultures were sampled in some conditions.

Abstract:
We introduce a novel computational approach, CoReCo, for comparative metabolic reconstruction and provide genome-scale metabolic network models for 49 important fungal species. Leveraging on the exponential growth in sequenced genome availability, our method reconstructs genome-scale gapless metabolic networks simultaneously for a large number of species by integrating sequence data in a probabilistic framework. High reconstruction accuracy is demonstrated by comparisons to the well-curated Saccharomyces cerevisiae consensus model and large-scale knock-out experiments. Our comparative approach is particularly useful in scenarios where the quality of available sequence data is lacking, and when reconstructing evolutionary distant species. Moreover, the reconstructed networks are fully carbon mapped, allowing their use in 13C flux analysis. We demonstrate the functionality and usability of the reconstructed fungal models with computational steady-state biomass production experiment, as these fungi include some of the most important production organisms in industrial biotechnology. In contrast to many existing reconstruction techniques, only minimal manual effort is required before the reconstructed models are usable in flux balance experiments. CoReCo is available at http://esaskar.github.io/CoReCo/.
