Wild Silkworm Cocoon Contains More Metabolites Than Domestic Silkworm Cocoon to Improve Its Protection
The silk of silkworm consists of fibroin fiber coated by sericins. In addition, some nonprotein components were also identified in the sericin fraction. The presence of nonprotein components in the silk has not been well explained. In the present study, methods based on gas chromatography-mass spectrometry were used to identify the metabolites in the cocoon silk from a wild silkworm and two dom...
متن کاملMapping of major quantitative trait loci for economic traits of silkworm cocoon.
The quantitative trait loci (QTLs) associated with cocoon traits in silkworms were mapped in 44 individuals of a backcross of Dazao females with hybrid F(1) males; the hybrid males were from females of inbred C(1)00 strain, which have white cocoons and superior cocoon traits, crossed with males of inbred strain Dazao, which have green cocoons and inferior cocoon traits. Nineteen putative major ...
متن کاملمقایسه اثرات استراتژی های متفاوت انتخاب بر عملکرد دو لاین تجاری کرم ابریشم
The aim of this research was to estimate the variance components and genetic parameters for silkworm cocoon traits using univariate and multivariate models, and comparison of average productivity and resistance traits among three different selection strategies in two commercial silkworm lines of 153 and 154. Genetic parameters of cocoon weight, cocoon shell weight and cocoon shell percenta...
متن کاملSilkworm Cocoon,a Biological Composite System
The cocoon of the commercial silkworm Bombyx mori is used as a model natural nonwoven composite to formulate a model for structural properties of nonwoven composites. The model is based upon open cell foam structures for the intrinsic undamaged elastic properties using the component materials in the cocoon, combined with the effect of gradual loss of connectivity in the interfiber bonding as th...
متن کاملGenetic Analysis of Response to Water Deficit Stress in Wheat Yield Traits with Generation Means and Variance Analysis
Drought stress is the most important environmental stress that affects many morphological, physiological and, especially, yield traits of arable crops. In this research, a cross between the cultivar Gaspard (dehydrated susceptible parent) and DN11 line (drought resistant parent) was performed. F1, F2, F3, BC1 and BC2 generations along with parents, were planted and compared in a randomized...
