Medaka Reciprocal cross RNAseq

ABSTRACT: Medaka fish is a long standing genetic model organism from the 1930s. Uniquely amongstvertebrates Medaka fish can be routinely inbred from the wild (laboratory mice are inbred, butthis does not happen as a routine process from wild individuals), leading to a large number offully inbred wild-derived strains. As part of a broader collaboration I am part of a project toinbred over 100 wild derived strains of Medaka and use them in a similar manner toArabidopsis and Drosophila wild derived lines.To help explore the phenotyping possibilities in this context, we have taken alreadyestablished wild Medaka lines and done reciprocal F1 crosses between 3 strains, and have 4tissues, and a number of parental tissues, giving a total of 40 samples. By doing RNA-seq onthese tissues we do a number of things:(a) assess the level of allele specific expression in Medaka(b) test whether there is any imprinting (parent of origin) in fish. This is thought to not be thecase, but in fact has not been well tested (not least because getting truly inbred fish is hard)(c) assess the level of random allelic activation in brain(d) assess the feasibility for RNAseq based phenotyping in Medaka, providing preliminarydata for future proposals.This data is part of a pre-publication release.
