Project description:Diaphorina citriis a vector of ‘CandidatusLiberibacter asiaticus,’(CLas), associated with citrus greening or Huanglongbing (HLB) disease in citrus. D. citriexhibits two group three different color morph variants, blueand non-blue (includes gray and yellow). Blue morphs have a greater capacity for long-distance flight while has lower efficiency in CLas transmission as compared to non-blue morphswhich influences disease epidemiology. In this study, wecompare the protein profilesof two-color morphsand evaluate the effect of CLas infection on abundance of pre-identified proteins in each color morphs. Our results showed that blue morphs have higher abundance of the immunity-associated proteins, while their abundance were upregulated dramatically in the non-blue morphcompared to blue morphin result of CLas infection. This observation proposes blue morph has higher immunity and CLas trigger the immunity in both morph while in non-blue’s response is late and non-effective.Further, challenging both color morphs byentomopathogenic fungi Beauveria bassiana, were showed significantly lower mortality in blue morph vs non-blue. Also, to test the effect of delayed response in CLas acquisition, we did CLas acquisition assay after priming immunity by feeding heat-killed Liberibacter crescens to both color-morphs. The obtained results were showed that priming immunity in non-blue morph can significantly decrease CLas acquisition as close as the level of CLas acquisition in blue morph. Taking all these in account propose that higher immunity in blue morph suppress CLas acquisition in a way that CLas acts as a pathogenand costly forACP. While in non-blue ACP, CLas triggers the immunity but the delayed immunity is not effective to block CLas from acquisition.

Project description:In the eastern United States the buckeye butterfly, Junonia coenia, shows a seasonal wing color polyphenism where adults emerging in the spring are pale brown, while those emerging in the autumn are dark red. This variation can be artificially induced in laboratory colonies, thus making J. coenia a useful model system to examine the developmental basis of phenotypic plasticity. We used RNA-seq to generate the first set of assembled transcripts for this species while simultaneously quantifying relative gene expression associated with development of alternative seasonal color morphs. The assembled consolidated wing transcriptome was 77.55 Mb. 16,251 contigs of over 1000bp in length were assembled, of which 3,145 were differentially expressed between stages and/or color morphs. Depending on the developmental stage, between 547 and 1420 transcripts were significantly differentially expressed between brown and red wing morphs. These extensive differences in gene expression stand in stark contrast to the much smaller numbers found in previous studies on genetic wing pattern variation, and suggest that environmentally induced phenotypic shifts may arise from very broad systemic processes. Overall gene ontology (GO) analyses revealed that genes associated with structural constituents of ribosomes and oxygen transport were significantly upregulated in the pale brown morph, while genes associated with peptidase activity were very significantly upregulated in the dark red morph. Focused analyses of candidate endocrine and pigmentation pathways revealed a number of notable genes upregulated in the red morph, including several ecdysone-related genes and cinnabar, an ommochrome pigment gene implicated in color pattern variation in other butterflies. Surprisingly, we found numerous melanin-related transcripts, including tan and yellow-family genes, strongly upregulated in the red morph, leading us to speculate that red pigmentation in autumn J. coenia may include red or brown melanins in addition to ommochromes. While we identified several endocrine and pigmentation genes as obvious candidates for color morph differentiation, we speculate that the majority of gene expression differences we observed were due to thermal stress response. The buckeye transcriptome provides a basis for further developmental studies of phenotypic plasticity.

Project description:The genome of the white-throated sparrow (Zonotrichia albicollis) contains an inversion polymorphism on chromosome 2 that is linked to predictable variation in a suite of phenotypic traits including plumage color, aggression, and parental behavior. Differences in gene expression between the two color morphs, which represent the two common inversion genotypes (ZAL2/ZAL2 and ZAL2/ZAL2m), are therefore of potential interest toward understanding the molecular underpinnings of these phenotypes. To identify genes that are differentially expressed between the two morphs and correlated with behavior, we quantified both behavior and gene expression in a population of free-living white-throated sparrows. We quantified behavioral responses to simulated territorial intrusions (STIs) early during the breeding season. In the same birds, we then performed a transcriptomewide analysis of gene expression in two behaviorally relevant brain regions, the medial amygdala and hypothalamus. Using network analyses, we identified modules of genes that were correlated with both morph and STI-induced singing behavior. The majority of these genes were located within the inversion, demonstrating the profound effect the inversion has on the expression of genes captured by the rearrangement. Gene pathway analyses revealed that in the medial amygdala, the most prominent pathways were those related to steroid hormone receptor activity. Within these pathways, the only gene encoding such a receptor was ESR1 (estrogen receptor alpha). Our results thus suggest that ESR1 and related genes are important for behavioral differences between the morphs.
