We have investigated the developmental expression of the small heat-shock proteins (hsps) during embryogenesis and in adult flies by immunocytology using an antibody that specifically identifies the small hsps. Antibody staining of unstressed early embryos reveals a predominantly cytoplasmic, homogeneous distribution of the small hsps throughout the embryo. At 6h of development small hsp expression can be identified in large, neuroblast-like cells within the extended germ band and in the brain of the embryo. During germ band contraction these cells appear to migrate to the midline where they align pairwise in a segmental pattern. After germ band contraction is complete a high level of small hsp expression can be observed in the midline glia (MECs) and in a cluster of six non-neuronal cells within the midline. In contrast to several other genes that are known to be important for embryogenesis and are expressed in the central nervous system (CNS) of embryos, CNS-specific expression of the small hsps is not restricted to the embryo but is also observed in the adult fly. In adult flies strong small hsp expression is observed in the brain, the thoracic ganglion and the leg nerves. Since the small hsps seem to be expressed predominantly in the glia of the nervous system, our data suggest a protective or stabilizing function of the small hsps within the nervous system during normal fly development, which is independent of the stress response.

Abstract Etiolated maize radicles (inbred Oh43) subjected to a brief heat shock synthesize a family of small heat shock proteins (≃18 kD) that is composed of at least 12 members. We previously described the cDNA-derived sequence of three maize shsp mRNAs (cMHSP18-1, cMHSP18-3, and cMHSP18-9). In this report, we demonstrate that the mRNA transcribed in vitro from one of these cDNAs (cMHSP 18-9) is responsible for the synthesis of three members of the shsp family, and we suggest that cMHSP18-3 may be responsible for the synthesis of three additional members and cMHSP18-1 for the synthesis of two other members of this family. The fact that these genes do not contain introns, coupled with the observations reported herein, suggest that maize may have established another method of using a single gene to produce a number of different proteins.
