Project description:We studied Y chromosomes from two geographically diverse populations of Drosophila melanogaster, and show that these Y chromosomes differentially modify the expression of hundreds of autosomal and X-linked genes. Genes showing Y-linked regulatory variation also show an association with immune response and pheromone detection, as well as proximity to the X chromosome euchromatin-heterochromatin boundary. 4-6 dual channel arrays per background, with males carrying two Y geographically diverse chromosomes competitively hybridized to each array. Dye-swap design was used.
Project description:These arrays were done in a study to probe Y-by-parent-of-origin effects on gene expression across two geographically diverse (Ohio, USA and Republic of Congo, Africa) Y-chromosome lineages (Cs or Con), and two modes of Y chromosome transmission (paternally or maternally).
Project description:We performed RNA-Seq of leaves of Oryza sativa L. ssp. japonica cv. Nipponbare 48 hours after inoculation with 10 geographically diverse strains of Xanthomonas oryzae pv. oryzicola, the causal agent of bacterial leaf streak. Results provide insight into the molecular basis of bacterial leaf streak, particularly the role of transcription activator-like effectors in the disease.
