Project description:Mucor species belongs to the Mucorales order within the phylum Mucoromycota, an early diverging fungal lineage. The purpose of this study was to investigate at the transcriptome scale the similarities and differences that could be linked to different lifestyles. Five strains pertaining to five species were studied: M. fuscus and M. lanceolatus, two species used in cheese ripening, M. racemosus, a recurrent cheese spoiler sometimes described as an opportunistic pathogen, M. circinelloides, often described as an opportunistic pathogen and M. endophyticus, a plant endophyte species.

Project description:Rapid responses to biotic and abiotic insults are crucial for plant survival. We examined the very early (10 min) wound transcriptome in order to increase our understanding regarding this critical intial phase of the plant response to stress. Our analysis revealed a rapid induction of stress-related transcripts that was distinct from the long term events which are dominated by jasmonic pathway responses. The transcriptome showed high correlation between the early wound response and other early but not late responses to innate immune interactions and other abiotic stresses. In addition those early responses were correlated with transcriptomes of response to singlet oxygen as displayed in the flu mutant. Singlet oxygen appears to be a signaling intermediate in the plant response to multiple stresses.

Project description:Blastocladiomycota, early diverging zoosporic (flagellated) lineages of fungi, are vastly understudied. This phylum includes the genus Coelomomyces which consists of more than eighty fungal species that are obligate parasites of arthropods. Coelomomyces lack a complete asexual life cycle, instead surviving through an obligate heteroecious alternation of generations life cycle. Despite their global distribution and interesting life cycle, little is known about Coelomomyces species. To begin to address this, we analyzed transcriptomes from across host-associated life stages including infection of larva and excised mature sporangia from the mosquito, Anopheles quadrimaculatus. We identified differentially expressed genes and over-enriched GO terms both across and within life stages and used these to make hypotheses about C. lativittatus biology. Generally, we found the C. lativittatus transcriptome to be a complex and dynamic expression landscape; GO terms related to metabolism and transport processes were over-enriched during infection and terms related to dispersal were over-enriched during sporulation. The C. lativittatus transcriptomes reported here are a valuable resource and may be leveraged toward furthering understanding of the biology of these and other early diverging fungal lineages.

Project description:To investigate the evolution of cold response in Pooideae, five species spanning early to later diverging lineages were sampled before and after subjecting them to a drop in temperature (17C to 6C), shorter days (12 to 8 hours of light) and less intensive light. Short-term response was sampled in the afternoon 8 hours after drop in temperature but 24 hours after the respective control sample to control for diurnal rhythm. Long-term response was sampled after 4 and 9 weeks in the morning directly after lights were turned on with a respective control sample also taken in the morning on the day before the temperature drop.

Project description:Environmental variation along the geographical space can shape populations by natural selection. In the context of global warming and changing precipitation regimes, it is crucial to understand the role of environmental heterogeneity in tropical trees adaptation, given their disproportional contribution to water and carbon biogeochemical cycles. Here, we investigated how heterogeneity in freshwater availability along tropical wetlands has influenced molecular variations of the black mangrove (Avicennia germinans). A total of 57 trees were sampled at seven sites differing markedly in precipitation regime and riverine freshwater inputs. Using 2,297 genome‐wide single nucleotide polymorphic markers, we found signatures of natural selection by the association between variations in allele frequencies and environmental variables, including the precipitation of the warmest quarter and the annual precipitation. Additionally, we found candidate loci for selection based on statistical deviations from neutral expectations of interpopulation differentiation. Most candidate loci within transcribed sequences were functionally associated with central aspects of drought tolerance or plant response to drought. Moreover, our results suggest the occurrence of the rapid evolution of a population, probably in response to sudden and persistent limitations in plant access to soil water, following a road construction in 1974. Observations supporting rapid evolution included the reduction in tree size and changes in allele frequencies and in transcript expression associated with increased drought tolerance through the accumulation of osmoprotectants and antioxidants, biosynthesis of cuticles, protection against protein degradation, stomatal closure, photorespiration and photosynthesis. We describe a major role of spatial heterogeneity in freshwater availability in the specialization of this typically tropical tree.
