In response to water deficit, increases in the activities of SOD, CAT, APX and POD were observed in all the three genotypes. Progressive increase in the activities of the antioxidant enzymes was observed with decreasing leaf water potentials from -0.75 MPa to -2.25 MPa. However BC2-59 showed significantly higher activities of all the three antioxidant enzymes under low water regimes compared to those from K-2 and MR-2. The results clearly suggest that low leaf water potentials induce the antioxidant enzymes in all the three genotypes of mulberry. Our data indicate that the genotype BC2-59 has efficient antioxidant system among the three cultivars which could protect the oxidative damage caused due to water limited conditions.","PeriodicalId":22665,"journal":{"name":"The journal of sericultural science of Japan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2000-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88126548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Silk is lustrous, well dyeable and heat-retaining. It absorbs and releases moisture quickly. Fbbroin also immobilizes enzymes (DEMURA and ASAKURA,1989), helps living cells multiply on it (MINOURA et al., 1995) and slowly diffuses medication (CHEN et al., 1990). Thus, silk is a promising material for a functional polymer as well as for clothes; however, it is inferior to another natural fiber, cotton, in some respects such as heat-resistance and friction resistance properties. Although cotton doesn't appear to be functional, it is tough and appears to be useful as a supporting material. This study has been carried out to determine the feasibility of a new material for textile fibers and functional substances by combining these two characteristic natural polymers: fibroin and cotton.

We purified an enzyme named as 35K protease from silkworm digestive juice (JIANG et al., 2000). This enzyme is a chymotrypsin-like protease and was inhibited by CI-8 (SHIRAI et al., 1997) in the larval hemolymph.

The LghIT2 gene, along with the signal sequence for secretion, was synthesized and transferred into the BmNPV genome to generate the recombinant virus BmLqhIT2. Larvae infected with BmLqhIT2 showed LqhIT2-specific symptoms at 48 h post injection (p. i.), stopped feeding at 60 h p. i., and became motionless by 84 h p. i. Particularly, the larvae infected with BmLghIT2 stopped moving 24 h earlier than those infected with BmAaIT, which expressed another insect-specific scorpion toxin AaIT. An N-terminal sequence and mass spectrometric analyses showed that BmLqhIT2 produced mature LghIT2. The present results suggest that LqhIT2 is more efficient than AaIT for improving the Insecticidal activity of baculoviruses.","PeriodicalId":22665,"journal":{"name":"The journal of sericultural science of Japan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2000-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73329243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was low during the early fifth instar, then sharply increased at the spinning stage and stayed high throughout the pupal stage. One of the major hemolymph esterases of B. mori, previously named BesB (blood esterase B type), was purified from day 1 pupae to homogeneity using procedures such as procainamide hydrochloride affinity chromatography. BesB had an apparent molecular weight of 58,000 and an isoelectric point of 4.6. It was most active at pH 6-7, and was stable around pH 7 to 9. The sequence of N-terminal 28 amino acid residues was partially homologous to previously reported esterases isolated from the peach-potato aphid Myzus persicae. In kinetic parameters, there were no differences in Km values from four tested substrates, but there were differences in Vmax values. BesB had the highest sensitivity to paraoxon and diisopropyl f luorophosphate (DFP), and was moderately affected by eserin sulfate, phenylmethylsulf onyl fluoride (PMSF) and chloromercuribenzoic acid (pCMB).
