Expression atlas of AAAP-536 and APC-8904 genes in asexual A. pisum before symbiont invasion. Staged embryos hybridized with DIG-labeled antisense (al) and sense riboprobes (m, n) of AAAP-536 and APC-8904. Signals were revealed by NBT/BCIP brown precipitates. All embryos are displayed with anterior of the germaria to the left. Arrowheads mark AAAP-536- and APC-8904-positive signals. Dashed lines indicate the location of germ cells. af Germarium, oocyte, and embryos before Buchnera invasion; transcripts of AAAP-536 were detected in the posterior syncytium (ps) of late stage 6 embryo. gl Germarium, oocyte, and embryos before Buchnera invasion; preferential expression of APC-8904 was detected in the posterior syncytium (ps) of late stage 6 embryo. m, n Oocytes and developing embryos hybridized with sense riboprobes. No signal was detected with AAAP-536 sense riboprobes, but ubiquitous background signals were detected with APC-8904 sense riboprobes. o Illustration displaying presented developmental stages.
