Genome wide microarray based expression profiles during early embryogenesis in diapause induced and non-diapause eggs of polyvoltine silkworm Bombyx mori

, : Genome wide microarray based expression profiles during early embryogenesis in diapause induced and non-diapause eggs of polyvoltine silkworm Bombyx mori. Genomics 102(4): 379-387

Diapause was induced in polyvoltine silkworm B. mori eggs and the molecular mechanism involved in diapause was investigated using a genome wide microarray. In diapause eggs, 638 and 675 genes were upregulated, while, in non-diapause eggs 1136 and 595 genes were upregulated at 18 h and 30 h, respectively after oviposition. Real-time qPCR analysis confirmed the expression of 20 genes, and the relative expression levels of the Aquaporin gene was highest among the 20 genes, followed by Sorbitol dehydrogenase-2 and Cytochrome b5 in diapause eggs, while, Kruppel homolog, Period and Relish were higher in non-diapause eggs. The upregulation of SDH-2 and cytochrome b5 indicate increased metabolic rate in diapause-destined embryos prior to the onset of diapause within 36 hours as a preparatory phase. This study provides an insight into the early molecular events for the induction and maintenance of diapause in B. mori.
