Figure 7From: Expression of catalase and retinoblastoma-related protein genes associates with cell death processes in Scots pine zygotic embryogenesis The localization of ATG5 expression in developing and mature Scots pine seeds. (A) ATG5 expression (blue signal) in the esr of the megagametophyte and in the nucellar layers at the early embryogeny. (B) ATG5 expression in the esr of the megagametophyte and in the maturating tracheids of the embryo in a mature seed. asr = arrow-shaped region, cc = corrosion cavity, e = embryo, esr = embryo surrounding region, m = megagametophyte, nc = nucellar cap, nl = nucellar layers, sr = suspensor remnants.
