Expression data from 0dpa ovules of GhHD-1 silenced and over-expression transgenic cotton lines

ABSTRACT: Cotton (Gossypium hirsutum L.) fibres are specialised trichomes that extend from the seedcoat. To date only a few genes directly involved in the differentiation of these epidermal cells have been identified. We have identified a HD-ZIP transcription factor, GhHD-1, expressed in trichomes and early fibres that might play a role in cotton fibre initiation. Here we characterise GhHD-1 from G. hirsutum and show, using reporter constructs and qRT-PCR, that they are expressed predominantly in epidermal tissues during early fibre development and in other tissues bearing epidermal trichomes. GhHD-1 silencing caused reduced trichome formation and delayed the timing of fibre initiation whereas constitutive over-expression of GhHD-1 increased the number of fibres initiating on the seed, but did not a
