Expression, regulation and function of the homeobox gene empty spiracles in brain and ventral nerve cord development of Drosophila.

abstract：:Mitochondrial large rRNA (mtlrRNA) and small rRNA (mtsrRNA) have been identified as components of germinal granules in Drosophila. We have previously reported that mtlrRNA is present on the germinal granules in Xenopus embryos. Here we report that mtsrRNA is also a common component of the germinal granules. Extra-mito...
