Project description:Grape berry development is a highly coordinated, intricate and complex process with many morphological, biochemical and physiological changes occurring during the ripening process. Equally, ripening is an organoleptic characteristic linked to fruit development. The fruits Seedless (FS) and Victoria (VT) grape varieties exhibit many morphological and phytochemical differences, but genetic mechanisms underlying them remain poorly explored. Herein, we comparatively analysed the phenotypic and transcriptomic patterns of Victoria (VT) and Flame Seedless (FS) grape varieties during berry development. We studied the physiological analysis and transcriptomic profiles sequencing were performed at four berry developmental stages time-points (40, 50, 60 and 80 DPA). Notably, the VT variety berry size was comparatively larger to the FS variety. At maturity, 80DPA, the FS soluble solids were 61.8% higher than VT. Further, a total of 4889 and 2802 DEG’s were identified from VT and FS 40 DPA to 80 DPA development stages, respectively. 1386 DEGs were common in the two varieties. GO analysis identified Cysteine biosynthetic process, response to red light, chlorophyll binding, polysaccharide biosynthetic process and chloroplast thylakoid membrane as some of the dominant terms under the biological processes, molecular function and cellular component categories.

Project description:Iron (Fe) and phosphorus (P) are essential nutrients for plants growth. Despite their abundance in soils, they are barely available for plants. In order to overcome these nutritional stresses, plants have evolved strategies including physiological, biochemical and morphological adaptations. Biosynthesis and release of low molecular weight compounds from the roots play a crucial role in P and Fe mobilization. White lupin (Lupinus albus L.) is considered a model plant for studying root exudates and for P-deficient adaptation. White lupin is able to markedly modify its root architecture by forming special structures called cluster roots, and modifies the rhizospheric soil characteristics by biosynthesising and releasing great amounts of exudates. These phenomena are quite well described in response to P deficiency, but there is few information on the adaptation of a cluster-root producing plant species to Fe deficiency. This prompted this work, aimed to characterize the physiological and transcriptomic responses of white lupin plants to Fe deficiency. Occurrence of Strategy I components and interactions with P nutrition has been also investigated in this work. Results showed a physiological and transcriptional link between the responses to Fe and P deficiency in white lupin roots. Phosphorus-deficient plants activated the Strategy I Fe acquisition mechanisms that lead to an enhanced Fe mobilization and translocation and that might help the P acquisition process. On the other hand, also the Fe deficiency enhanced the phosphate acquisition and some P-deficient-responsive genes were overexpressed.

Project description:Background: Earlobe color is a typical external trait in chicken. There are some previous studies showing that the chicken white/red earlobe color is a polygenic and sex-linked trait in some breeds, but its molecular genetic and histological mechanisms still remain unclear. Methods: We herein utilized histological section, genome-wide association study (GWAS) and RNA-seq, further to investigate the potential histological and molecular genetic mechanisms of white/red earlobe formation in Qiangyuan Partridge chicken (QYP). Results: through histological section analysis, we found the dermal papillary layer of red earlobes had many more blood vessels than that of white earlobes. And we identified a total of 44 SNPs from Chromosome 1, 2, 3, 4, 9, 10, 11, 13, 19, 20, 23 and Z, that was significantly associated with the chicken white/red earlobe color from GWAS, along with 73 significantly associated genes obtained (e.g., PIK3CB, B4GALT1 and TP63), supporting the fact that the white/red earlobe color was also polygenic and sex-linked in QYP. Importantly, PIK3CB and B4GALT1 are both involved in the biological process of angiogenesis, which may directly give rise to the chicken white earlobe formation through regulating blood vessel density in chicken earlobe. Additionally, through contrast of RNA-seq profiles between white earlobe skins and red earlobe skins, we further identified TP63 and CDH1 differentially expressed. Combined with the existing knowledge of TP63 in epithelial development and tumor angiogenesis, we propose that down-regulated TP63 in white earlobes may play roles in thickening the skin and decreasing the vessel numbers in dermal papillary layer, thereby contributing to the white earlobe formation via paling the redness of the skin in QYP, but the specific mechanism remains further clarified. Conclusion: our findings advance the existing understanding of the white earlobe formation, as well as provide new clues to understand the molecular mechanism of chicken white/red earlobe color formation.

Project description:Obesity is characterized by an increase in the size and the number of adipocytes. However, the mechanisms responsible for the formation of adipocytes during development and the molecular mechanisms regulating their increase and maintenance in adulthood are poorly understood. Here, we report the use of leptin-luciferase BAC transgenic mice to track white adipose tissue (WAT) development and guide the isolation and molecular characterization of adipocytes during development using DNA microarrays. These data reveal distinct transcriptional programs that are regulated during murine WAT development in vivo.

Project description:Malaria parasites induce morphological and biochemical changes in the membranes of parasite-infected red blood cells (iRBCs) for propagation. Artemisinin combination therapies are the first-line antiplasmodials in endemic countries. However, the mechanism of action of artemisinin is unclear, and drug resistance decreases long-term efficacy. To understand whether artemisinin targets or interacts with iRBC membrane proteins, this study investigated the molecular changes caused by dihydroartemisin (DHA), an artemisinin derivative, in Plasmodium falciparum 3D7 using a combined transcriptomic and membrane proteomic profiling approach.
