Project description:Many fungi form complex three-dimensional fruiting bodies, within which the meiotic machinery for sexual spore production has been considered to be largely conserved over evolutionary time. Indeed, much of what we know about meiosis in plant and animal taxa has been deeply informed by studies of meiosis in Saccharomyces and Neurospora. Nevertheless, the genetic basis of fruiting body development and its regulation in relation to meiosis in fungi is barely known, even within the best studied multicellular fungal model Neurospora crassa. We characterized morphological development and genome-wide transcriptomics in the closely related species Neurospora crassa, Neurospora tetrasperma, and Neurospora discreta, across eight stages of sexual development. Despite diverse life histories within the genus, all three species produce vase-shaped perithecia. Transcriptome sequencing provided gene expression levels of 2479 orthologous genes among all three species. Expression of key meiosis genes and sporulation genes, corresponded to developmental differences among these Neurospora species during sexual development. Screening N. crassa knockout crosses of genes selected for their expression differences across species, eight genes, whose functions were previously unknown, are found to be critical for the successful formation of perithecia. The absence of these genes in mutant crosses resulted in either no perithecium formation or in arrested development at an early stage. Our results provide insight into the genetic basis of Neurospora sexual reproduction, which is also of great importance with regard to other multicelluar ascomycetes, including fungal pathogens closely related to Neurospora in the Sordariomycetes, such as Fusarium spp, Magnaporthe oryzae, and Nectria haematococca mRNA were sampled and compared from eight time points across sexual reproduction in three Neurospora species

Project description:Sexual reproduction (meiosis and syngamy) is the major form of reproduction in diploid Boechera species, but most species hybrids reproduce by apomixis (unreduced gametophyte formation followed by parthenogenesis of the unreduced egg). In this study, we used Arabidopsis microarrays to detail global programs of gene expression underlying sexual and apomictic modes of reproduction.

Project description:Pseudo-nitzschia multistriata is a planktonic diatom species with a diplontic life cycle comprising a short sexual phase during which gametes are produced from the encounter of two diploid cells of opposite mating type (MT). Gene expression studies have highlighted the presence of substantial changes occurring at the onset of sexual reproduction. Collectively, there is clear evidence of a chemical cross talk which mediates the mating step.Herein, we have hypothesized that these major transcriptomic changes are associated to variations in the amount and nature of the metabolites produced by the cells. In order to investigate such chemical diversity in an unbiased manner, we undertook an untargeted metabolomics approach. Liquid chromatography – tandem mass spectrometry was applied to investigate the differences in the metabolic profiles between control cells in the vegetative phase (MT+ and MT-) and mixed strains of opposite MTs (cross) undergoing sexual reproduction. Of the 2408 high-quality features obtained, 70 known metabolites could be identified based on in-house libraries and online databases; molecular networking proved valuable to classify additional 47 non-identified features.The present exploratory study provides an overview of the chemical diversity detectable in P. multistriata, presenting a dynamic picture of the changes occurring during sexual reproduction. In particular, the reduction of phytol detected in the cross can be linked to the general downregulation of photosynthesis during sexual reproduction observed elsewhere. The dysregulation of other metabolites stands as a starting point for the understanding of the mechanisms regulating sexual reproduction: a metabolite that was tentatively identified as 7-dehydrodesmosterol exhibited the highest upregulation in the comparison between the two MTs of opposite sex, as well as between MT+ vs cross.The effects of extraction solvents and harvesting times on the ensemble of endo-metabolites were also analyzed.
