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:As ambush-hunting predators that consume large prey after long intervals of fasting, Burmese pythons evolved with unique adaptations for regulating organ structure and function. Among these is cardiac hypertrophy that develops within three days following a meal (1, 2), which we previously showed was initiated by circulating growth factors (3). Post-prandial cardiac hypertrophy in pythons also rapidly regresses with subsequent fasting (2); however, the molecular mechanisms that regulate the dynamic cardiac remodeling in pythons during digestion are largely unknown. In this study, we employed a multi-omics approach coupled with targeted molecular analyses to examine remodeling of the python ventricular transcriptome and proteome throughout digestion. We found that forkhead box protein O1 (FoxO1) signaling was suppressed prior to hypertrophy development and then activated with regression, which coincided with decreased and then increased expression, respectively, of FoxO1 transcriptional targets involved in protein degradation. To define the molecular mechanistic role of FoxO1 in hypertrophy regression, we used cultured mammalian cardiomyocytes treated with post-fed python plasma. Hypertrophy regression both in pythons and in vitro coincided with activation of FoxO1-dependent autophagy; however, introduction of a FoxO1-specific inhibitor prevented both regression of cell size and autophagy activation. Finally, to determine if FoxO1 activation could induce regression, we generated an adenovirus expressing a constitutively active FoxO1. FoxO1 activation was sufficient to prevent and reverse post-fed plasma-induced hypertrophy, which was partially prevented by autophagy inhibition. Our results indicate that modulation of FoxO1 activity contributes to the dynamic ventricular remodeling in post-prandial Burmese pythons.
