Project description:Purpose: The goal of the current study was to find the candidate genes responsible for the habita specific clock variation in N. discreta. Methods: We performed RNA-seq experiment using four strains ; African parent (FGSC8831), North American parent (FGSC 8578) and two representative progeny representing African clock phenotype (N309-89) and North American clock phenotype (N309-50). Results: We identified one candidate gene that meets our criteria; confirmed it's expression by qPCR and it's expression pattern is associated with parent genotype. Conclusions: Our approach using the expression profiles and SNP data of two parents and two representative progeny led us to identify a candidate gene for a complex clock adaptation phenotype.

Project description:Gut microbiota participates in diverse metabolic and homeostatic functions related to health and well-being. Individual variation in its composition depends on many factors including dietary factors. We profiled enzymatic activity of fecal microbiota in 63 healthy adult individuals using metaproteomics, and identified Bacteroides and Prevotella –derived microbial CAZy (carbohydrate-active) enzymes involved in glycan foraging. One particular profile with many Bacteroides-derived CAZy was identified in one-third of subjects (n=20), and it associated with high abundancy of Bacteroides in most subjects. In other subjects (n=8) with dietary parameters similar to former, microbiota showed intense expression of Prevotella-derived CAZy including exo−beta−(1,4)−xylanase, xylan-1,4−beta−xylosidase, alpha−L−arabinofuranosidase and several other CAZy belonging to glycosyl hydrolase families involved in digestion of complex plant-derived polysaccharides. This associated invariably with robust representation of Prevotella in gut microbiota, while subjects with intermediate representation of Prevotella showed no CAZy profile. Identification of Bacteroides- and Prevotella-derived CAZy in microbiota proteome and their association with robust differences in microbiota composition, the latter with exceptionally high Prevotella abundancy in the gut, are in evidence of individual variation in metabolic adaptation of gut microbiota with an impact on colonizing competence.

Project description:Local adaptation can play a fundamental role in the isolation of populations. While less well-studied than differentiation in sequence variation, changes in transcriptional variation during speciation also are fundamental to the evolutionary process. Drosophila mojavensis offers an unprecedented opportunity to examine the role of transcriptional differentiation in local adaptation. Drosophila mojavensis is a cactophilic fly composed of four ecologically distinct subspecies that inhabit the deserts of western North America. Each of the four subspecies utilizes necrotic tissue of different cactus host species characterized by distinct chemical profiles. The subspecies in Baja California, Mexico uses Stenocereus gummosus (Agria), in mainland Sonora it uses S. thurberi (Organ Pipe), in the Mojave Desert the host is Ferocactus cylindraceus (Red Barrel) and in Santa Catalina Island, USA, Opuntia littoralis (Prickly Pear) is the host. In this chapter we examine how the adaptation to the different environmental conditions across the four subspecies have shaped their transcriptional profiles. Using complete D. mojavensis genome microarrays we examined the transcriptome of third instar larvae from all four subspecies reared in standard laboratory media free of necrotic cactus-derived compounds. This experimental strategy focused on differences between constitutively expressed genes and not genes induced by necrotic cactus-derived compounds. The subspecies exhibited significant differential expression of genes that likely underlie the adaptation to different cactus hosts, such as detoxification genes (Glutathione S-transferases, Cytochrome P450s and UDP-Glycosyltransferases) and chemosensory genes (Odorant Receptors, Gustatory Receptors and Odorant Binding Proteins).
