Biosynthesis of cytochrome c in developing pupae of Samia cynthia.
The level of cytochrome c in diapausing pupae of the silkworm Platysamia cecropia is very low (1, 2) ; however, the concentration of the protein in the flight muscles increases rapidly during the final period of development, reaching the high adult level shortly after the emergence of the moth (3). The present paper shows that an essentially similar pattern of development occurs in a related sa...
متن کاملControl of discontinuous gas exchange in Samia cynthia: effects of atmospheric oxygen, carbon dioxide and moisture.
The evolution of discontinuous gas exchange (DGE) in insects is highly controversial. Adaptive hypotheses which have obtained experimental support include a water savings mechanism for living in dry environments (hygric hypothesis), a reduction in oxidative damage due to a high-performance oxygen delivery system (oxidative damage hypothesis), and the need for steep intratracheal partial pressur...
متن کاملGenetic analysis of scattered populations of the Indian eri silkworm, Samia cynthia ricini Donovan: Differentiation of subpopulations
Deforestation and exploitation has led to the fragmentation of habitats and scattering of populations of the economically important eri silkworm, Samia cynthia ricini, in north-east India. Genetic analysis of 15 eri populations, using ISSR markers, showed 98% inter-population, and 23% to 58% intra-population polymorphism. Nei's genetic distance between populations increased significantly with a...
متن کاملInsect immunity. I. Characteristics of an inducible cell-free antibacterial reaction in hemolymph of Samia cynthia pupae.
Pupae of the silk moth, Samia cynthia, were found to contain an inducible antibacterial activity in their hemolymph. This immunity response was provoked by primary infections with either Escherichia coli K-12 or Enterobacter cloacae. In both cases the antibacterial activity was directed chiefly towards E. coli. During standard conditions, 1% of hemolymph could kill 10(3) to 10(4) viable E. coli...
متن کاملComparative transcriptome analysis reveals significant metabolic alterations in eri-silkworm (Samia cynthia ricini) haemolymph in response to 1-deoxynojirimycin
Samia cynthia ricini (Lepidoptera: Saturniidae) is an important commercial silk-producing insect; however, in contrast to the silkworm, mulberry leaves are toxic to this insect because the leaves contain the component 1-deoxynojirimycin (DNJ). A transcriptomic analysis of eri-silkworm haemolymph was conducted to examine the genes related to different metabolic pathways and to elucidate the mole...
