Localization of dmeglob2, dmeglob3 and dviglob2/3 mRNA. mRNA in situ hybridization of Drosophila adult testes with glob2, glob3 and glob2/3 antisense RNA-probes. Arrows indicate stained regions. (A) glob2 expression in D. melanogaster. (B) glob3 expression in D. melanogaster. (C) glob2/3 expression in D. virilis. All three globins analyzed show expression in primary spermatocytes, meiotic spermatocytes, round spermatids and early differentiating spermatids. Abbreviations: (sc) stem cells; (mc) mitotic cells; (ps) primary spermatocytes; (ms) meiotic spermatocytes; (rs) round spermatids; (ds) early differentiating spermatids; (es) late elongating spermatids.
