Spatial expression of the mevalonate enzymes involved in juvenile hormone biosynthesis in the corpora allata in Bombyx mori
چکیده انگلیسی

The developmental expressions of the mRNA of JH synthetic enzymes have been studied using homogenates of the corpora cardiaca–corpora allata (CC–CA) complexes in Bombyx mori [Kinjoh, T., Kaneko, Y., Itoyama, K., Mita, K., Hiruma, K., Shinoda, T., 2007. Control of juvenile hormone biosynthesis in Bombyx mori: cloning of the enzymes in the mevalonate pathway and assessment of their developmental expression in the corpora allata. Insect Biochemistry and Molecular Biology 37, 808–818]. The in situ hybridization analyses in the CC–CA complex showed that the distribution of the mRNAs of all the mevalonate enzymes and juvenile hormone (JH) acid O-methyltransferase occurred only in the CA cells, indicating that the fluctuations of the enzyme mRNA amounts in the CC–CA complexes were derived solely from the CA. In addition, the size of the CA and their nuclei was not associated with the JH synthetic activity by the CA until the pharate adult. Only female adult CA synthesized JH in B. mori, and the CA and the nuclei were significantly larger than those of male CA which do not synthesize JH.
