RNA-seq of coding RNA of moss Funaria hygrometrica samples from three haploid (gametophyte) stages and three diploid (sporophyte) stages

ABSTRACT: We experimentally generated a genome-wide gene expression data. To this end, we first collected samples of three important haploid developmental stages, specifically germinating spores (gametophyte_1), protonemata (gametophyte_2) and young gametophores (gametophyte_3) (four biological replicates each). We also collected three developmental stages of the diploid phase (sporophyte), specifically sporophytes shorter than 5mm (sporophyte_1), elongated needle-like sporophytes (sporophyte_2), and sporophytes with swollen capsules (sporophyte_3)

In diploid organisms, selfing reduces the efficiency of selection in removing deleterious mutations from a population. This need not be the case for all organisms. Some plants, for example, undergo an extreme form of selfing known as intragametophytic selfing, which immediately exposes all recessive deleterious mutations in a parental genome to selective purging. Here, we ask how effectively deleterious mutations are removed from such plants. Specifically, we study the extent to which deleteriou  ...[more]
