What is Localization of mitochondrial large ribosomal RNA in the myoplasm of the early ascidian embryo about?

Mitochondrial large ribosomal RNA (mtlrRNA) is transferred out of mitochondria and associates with germinal granules in __Drosophila__ and __Xenopus__ embryos. It has been revealed that mtlrRNA outside of mitochondria is required for formation of the germ‐line progenitor, or pole cells in __Drosophila__. In the present study, the distribution of mtlrRNA was examined in embryos of the ascidian, __Halocynthia roretzi__, during cleavage stages by whole‐mount __in situ__ hybridization. Until the 4‐cell stage, the distribution of mtlrRNA coincided with that of mitochondria, which are localized to the cortical cytoplasm in the posterior region of the embryos. Both mitochondria and mtlrRNA were preferentially partitioned into muscle‐lineage blastomeres during cleavage stages. After the 8‐cell stage, a discrepancy in intracellular localization of mitochondria and mtlrRNA became evident. Mitochondria translocated into central yolkless cytoplasm, while mtlrRNA remained in the posterior cortex in the posterior muscle‐lineage blastomeres. The significance of the cortical localization of mtlrRNA in muscle precursor cells in ascidian embryos is obscure. However, the results suggest that mtlrRNA
