Project description:This study provides a screen of sexually dimorphic tissue-specific (brain) gene expression in fruit flies age 3, 7, and 14 days post-eclosion. This work can be used as a baseline reference point for comparing sex-specific brain gene expression levels in fruit flies under stress.

Project description:Five different mitochondrial strains were introgressed in male and female fruit flies with identical (w1118) nuclear genetic background. 40 samples: Five mitochondrial strains, two independent introgressions, two sexes, two biological replicates.
Project description:Cucumber (Cucumis sativus L.) fruit is a type of fleshy fruit that is harvested immaturely. Early fruit development directly determines the final fruit length and diameter, and consequently the fruit yield and quality. Different cucumber varieties display huge variations of fruit length, but how fruit length is determined at the molecular level remains poorly understood. To understand the genes and gene networks that regulate fruit length in cucumber, high throughout RNA-seq data were used to compare the transcriptomes of early fruit from two near isogenic lines with different fruit lengths. 3955 genes were found to be differentially expressed, among which 2368 genes were significantly up-regulated and 1587 down-regulated in the line with long fruit. Microtubule and cell cycle related genes were dramatically activated in the long fruit, and transcription factors were implicated in the fruit length regulation in cucumber. Thus, our results built a foundation to dissect the molecular mechanism of fruit length control in cucumber, a key agricultural trait of significant economic importance.
Project description:Study of transcriptome level changes in Drosophila melanogaster populations with divergent reproduction and lifespan patterns A 120 chip study using mRNA recovered from unmated female fruit flies 35 generations after selection for contrasting life history traits. The study includes samples from five age classes and two tissues of flies derived from three replicated populations.
