The combining ability effects of five silkworm (Bombyx mori L.) strains and their 20 F₁'s including reciprocals were analysed in a 5x5 diallel cross for seven silk yield attributes, viz. effective rate of rearing (ERR), a measure of survival, cocoon yield, cocoon weight, shell weight, raw silk percentage, silk filament length/cocoon and silk reelability. Higher values of specific combining ability (SCA) than the corresponding general combining ability (GCA) for all the attributes except ERR and cocoon yield are indicative of non-additive gene action. The parental strain JC2P was the best general combiner for all the attributes, except cocoon yield. The highest general combining ability effect for cocoon yield was shown by N4. The highest desirable or positive SCA effects resulted from N4 × SH2 (all the attributes except shell weight), JC2P × 14M (all the attributes except cocoon weight and shell weight), 14M × SH2 (all the attributes except ERR), N4 × SPJ1 (all the attributes except shell weight and raw silk percentage). Only one reciprocal, namely SPJ1 × N4, showed positive effects for all the attributes except silk reelability. The improvement of cocoon yield through mass selection followed by intermating and the use of the parental strain JC2P in future cross breeding are discussed.

Bombyx mori. L. (CSR2XCSR4) is a bivolitne crossbreed that produces high quantity of silk. The weights of worms and glands are directly related to the yield of silk, higher larval weights leads to higher silk production. In the present study, quantitative parameters of 5th instar and pupal stages of silkworm larvae were observed. The analysis of quantitative estimation showed that the maximum weights and lengths of silk gland and silk worm were recorded on 7th day of 5th instar larval stage. The day dependent variation in protein concentration was observed in total silk gland 5th instar larval and pupal stages.

The telomere structures in Bombyx mori are thought to be maintained mainly by the transposition of the specialized telomeric retroelements SART and TRAS. The silkworm genome has telomeric TTAGG repeats and telomerase, but this telomerase displays little or no activity. Here, we report that the transcription of the telomeric retroelements SART1 and TRAS1 is suppressed by the silkworm Piwi subfamily proteins BmAgo3 and Siwi. The silkworm Piwi subfamily was found to be expressed predominantly in the gonads and early embryo, as in other model organisms, but in BmN4 cultured cells, these proteins formed granules that were separate from the nuage, which is a different behaviour pattern. The expression of TRAS1 was increased in BmN4 cells when BmAgo3 or Siwi were silenced by RNAi. Our results suggest that B. mori Piwi proteins are involved in regulating the transposition of telomeric retroelements, and that the functional piRNA pathway is conserved in BmN4 cultured cells.

In this study, we report the cloning and characteristics of an adiponectin-like receptor gene from Bombyx mori (BmAdipoR) with highly conserved deduced amino-acid sequences and similar structure to the human adiponectin receptor (AdipoR). Structural analysis of the translated cDNA suggested it encoded a membrane protein with seven transmembrane domains. BmAdipoR was found to be expressed in multiple tissues and highly expressed in Malpighian tubules, fat body and testis. BmNPV (Bombyx morinucleopolyhedrovirus) bacmid system combined with confocal microscopy revealed that BmAdipoR was targeted to the cell membrane. We also found that infection with BmNPV did not have an effect on BmAdipoR mRNA quantity in the midgut of susceptible Bombyx moristrain (306) at 48 h, but BmAdipoR mRNA quantity increased significantly at 72 h. We concluded that BmAdipoR gene was a membrane protein ubiquitously expressed in Bombyx moritissues and that its expression was altered by treating with BmNPV.

Random amplification of polymorphic DNA polymerase chain reaction (RAPD-PCR) was carried out to assess the genetic diversity of five new microsporidian isolates viz., NIWB-11bp, NIWB-12n, NIWB-13md, NIWB-14b and NIWB-15mb identified from the silkworms. A type species, NIK-1s_mys was used as control for comparison. Differences in the spore shape, length and width were observed. Of the 30 decamer random primers tested, 22 primers gave repeatable RAPD profiles and yielded a total of 143 fragments, of which 78 were polymorphic (55%). The resulting data was used to derive genetic similarity values for constructing a dendrogram. The neighbour joining method based on Dice coefficients indicate a major cluster comprising NIK-1s_mys, NIWB-11bp and NIWB-12n, whereas NIWB-13md, NIWB-14b and NIWB-15mb appear to be different from each other as well from the major cluster mentioned above which includes the type species (NIK-1s_mys). Based on the reproducibility of RAPD profiles, we are able to identify these microsporidians as different isolates. The RAPD technique may be useful in detecting sources of infection of this economically important domestic insect.

Serpins are a broadly distributed family of protease inhibitors. In this study, the gene encoding Bombyx mori serpin-2 (Bmserpin-2) was cloned and expressed in E. coli. The Bmserpin-2 cDNA contains a 1125 bp open reading frame (ORF). The deduced protein has 374 amino-acid residues, contains a conserved SERPIN domain and shares extensive homology with other invertebrate serpins. RT-PCR analysis showed that Bmserpin-2 was expressed in all developmental stages of B. mori larvae and various larval tissues. Subcellular localization analysis indicated that Bmserpin-2 protein was located in the cytoplasm. Interestingly, real-time quantitative PCR revealed that the expression of Bmserpin-2 in the midgut of susceptible B. mori strain 306 significantly increased at 72 hours post inoculation (hpi) when infected with BmNPV. However, there was no significant increase of the Bmserpin-2 expression in resistant strain NB infected with BmNPV. Thus, our data indicates that Bmserpin-2 may be involved in B. mori antiviral response.
