Transport of Germ Plasm on Astral Microtubules Directs Germ Cell Development in Drosophila
BACKGROUND In many organisms, germ cells are segregated from the soma through the inheritance of the specialized germ plasm, which contains mRNAs and proteins that specify germ cell fate and promote germline development. Whereas germ plasm assembly has been well characterized, mechanisms mediating germ plasm inheritance are poorly understood. In the Drosophila embryo, germ plasm is anchored to ...
متن کاملSpatiotemporal localization of germ plasm RNAs during zebrafish oogenesis
In zebrafish, primordial germ cells (PGCs) are determined by a specialized maternal cytoplasm, the germ plasm, which forms at the distal ends of the cleavage furrows in 4-cell embryos. The germ plasm includes maternal mRNAs from the germline-specific genes such as vasa and nanos1, and vegetally localized dazl RNA is also incorporated into the germ plasm. However, little is known about the distr...
متن کاملLocalization of mitochondrial large ribosomal RNA in germ plasm of Xenopus embryos
In Xenopus, factors with the ability to establish the germ line are localized in the vegetal pole cytoplasm, or germ plasm, of the early embryo [1-3]. The germ plasm of Xenopus, and of many other animal species including Drosophila, contains electron-dense germinal granules which may be essential for germ-line formation [4-5]. Several components of the germinal granules have so far been identif...
متن کاملXcat RNA is a translationally sequestered germ plasm component in Xenopus
In Xenopus, the inheritance of germ plasm by a small subset of blastomeres during early development is thought to direct these cells into the germ cell lineage. We show that Xcat2 RNA, related to Drosophila nanos, is a germ plasm component that is translationally repressed during oogenesis. Xcat2 protein was not detected in oocytes at times prior to, or after its RNA was localized in germ plasm...
متن کاملDEADSouth protein localizes to germ plasm and is required for the development of primordial germ cells in Xenopus laevis
DEADSouth mRNA is a component of germ plasm in Xenopus laevis and encodes a DDX25 DEAD-box RNA helicase. To determine the intracellular localization of DEADSouth protein, we injected mRNA encoding DEADSouth tagged with mCherry fluorescent protein into fertilized eggs from transgenic Xenopus expressing EGFP fused with a mitochondrial targeting signal. The DEADSouth-mCherry fusion protein was loc...
