“…In addition, dst2 and dst1 , encoding a blue-light photoreceptor and a flavin adenine dinucleotide-binding protein, were shown to play a role in blue light sensing. In agreement with previous experiments, strains defective in these two proteins were unable to form fruiting bodies, showing that blue light is an essential environmental trigger of mushroom development [16]. Most recently, C. cinerea strains carrying mutations in the putative component of the SWI/SNF chromatin remodeling complex snf5 (CC1G_15539) were shown to be defective in fruiting initiation, suggesting that epigenetic reprogramming of loci occurs during fruiting body formation [17].…”

“…Mutations in rmt1 , ubc2 and snf5 [14, 15, 17] block development before initials are formed (48 h before S1P develop). In contrast, dst1 , dst2 , eln3 and exp1 are involved in processes taking place in stage 2 primordia (24 h after S1P), immature fruiting bodies (48–72 h after S1P) and decaying fruiting bodies (72 h after S1P) [6, 11, 12, 16]. Thus, a possible explanation of our results is that these genes might be regulated before or after the formation of S1P takes place.…”

Comparative transcriptomics of the model mushroom Coprinopsis cinerea reveals tissue-specific armories and a conserved circuitry for sexual development

BackgroundIt is well known that mushrooms produce defense proteins and secondary metabolites against predators and competitors; however, less is known about the correlation between the tissue-specific expression and the target organism (antagonist) specificity of these molecules. In addition, conserved transcriptional circuitries involved in developing sexual organs in fungi are not characterized, despite the growing number of gene expression datasets available from reproductive and vegetative tissue. The aims of this study were: first, to evaluate the tissue specificity of defense gene expression in the model mushroom Coprinopsis cinerea and, second, to assess the degree of conservation in transcriptional regulation during sexual development in basidiomycetes.ResultsIn order to characterize the regulation in the expression of defense loci and the transcriptional circuitries controlling sexual reproduction in basidiomycetes, we sequenced the poly (A)-positive transcriptome of stage 1 primordia and vegetative mycelium of C. cinerea A43mutB43mut. Our data show that many genes encoding predicted and already characterized defense proteins are differentially expressed in these tissues. The predicted specificity of these proteins with regard to target organisms suggests that their expression pattern correlates with the type of antagonists these tissues are confronted with. Accordingly, we show that the stage 1 primordium-specific protein CC1G_11805 is toxic to insects and nematodes. Comparison of our data to analogous data from Laccaria bicolor and Schizophyllum commune revealed that the transcriptional regulation of nearly 70 loci is conserved and probably subjected to stabilizing selection. A Velvet domain-containing protein was found to be up-regulated in all three fungi, providing preliminary evidence of a possible role of the Velvet protein family in sexual development of basidiomycetes. The PBS-soluble proteome of C. cinerea primordia and mycelium was analyzed by shotgun LC-MS. This proteome data confirmed the presence of intracellular defense proteins in primordia.ConclusionsThis study shows that the exposure of different tissues in fungi to different types of antagonists shapes the expression pattern of defense loci in a tissue-specific manner. Furthermore, we identify a transcriptional circuitry conserved among basidiomycetes during fruiting body formation that involves, amongst other transcription factors, the up-regulation of a Velvet domain-containing protein.Electronic supplementary materialThe online version of this article (doi:10.1186/1471-2164-15-492) contains supplementary material, which is available to authorized users.

“…Different culture conditions and different genetic backgrounds may also play a role (Tsusu e, 1969;Iten, 1970;Kamada et al, 1978;Moore et al, 1979;McLaughlin, 1982;Rosin and Moore, 1985a,b;Hammad et al, 1993a;Lu, 2000;Liu, 2001;Liu et al, 2006). Starting from the undifferentiated secondary hyphal knots, two to four days are variably given in the literature as times required for completion of primordia formation or, quite often, timing and kinds of early events are left open (Borris, 1934;Takemaru and Kamada, 1972;Morimoto and Oda, 1973;Kamada et al, 1978;Moore et al, 1979;Ballou and Holton, 1985;Muraguchi and Kamada, 1998;Boulianne et al, 2000;Lu, 2000;Kamada, 2002;Walser et al, 2003;K€ ues et al, 2004;Liu, 2001;Kamada et al, 2010;Shioya et al, 2013).…”

“…Among the environmental stimuli, light is central to the development of fruiting bodies. Light responses are orchestrated to a large extent by blue light receptors, primarily by the photosensor white-collar genes (WC1-2) first identified in N. crassa (56,61,62). One of the key regulatory pathways of fruiting body development is the velvet complex (VelB, VeA, and LaeA in A. nidulans), which controls secondary metabolism and sexual reproduction in response to light stimuli (63,64).…”

Six Key Traits of Fungi: Their Evolutionary Origins and Genetic Bases

et al. 2017

The fungal lineage is one of the three large eukaryotic lineages that dominate terrestrial ecosystems. They share a common ancestor with animals in the eukaryotic supergroup Opisthokonta and have a deeper common ancestry with plants, yet several phenotypes, such as morphological, physiological, or nutritional traits, make them unique among all living organisms. This article provides an overview of some of the most important fungal traits, how they evolve, and what major genes and gene families contribute to their development. The traits highlighted here represent just a sample of the characteristics that have evolved in fungi, including polarized multicellular growth, fruiting body development, dimorphism, secondary metabolism, wood decay, and mycorrhizae. However, a great number of other important traits also underlie the evolution of the taxonomically and phenotypically hyperdiverse fungal kingdom, which could fill up a volume on its own. After reviewing the evolution of these six well-studied traits in fungi, we discuss how the recurrent evolution of phenotypic similarity, that is, convergent evolution in the broad sense, has shaped their phylogenetic distribution in extant species.
