The 4th instar larvae of the silkworm,Bombyx mori L, when treated with anti-juvenile hormone (Jinlu) had its larval period extended by 2 days and the total larval period shortened
by about 4 days. The conversion ratio of tetramolters into trimolters was 100%. But anti-juvenile hormone administration to
the 5th instar larvae lengthened the silkworm age by one day. When anti-juvenile hormone was administered, we could find many
neurosecretory granules of the brain transferred to the cells of the corpora allata, but there was little endoplasmic reticulum.
In the prothoracic gland, the micropile edge was clear and there were large nucleoli, mitochondria and endoplasmic reticulum.
This study was carried out to show that anti-JH compound inhibits the secretion of Juvenile hormone in silkwormBombyx mori L. The investigation revealed that the antijuvenile hormone inhibited the secretion of corpora allata and initiated the activity
of the prothoracic gland.

1-deoxynojirimycin (1-DNJ) contents in the silkworm,Bombyx mori,at different developmental stages and tissues were investigated by using reverse-phase high-performance liquid chromatography. The 1-DNJ contents of silkworm larvae change significantly with their developmental stages. The male larvae showed higher accumulation efficiency of 1-DNJ than the females and also a significant variation was observed among the silkworm strains. The present results show that tissue distribution of 1-DNJ was significantl... 相似文献

Since preparation and solubilization of protein samples are crucial factors in proteome research, the authors established
a sequential extraction technique to prepare protein samples from the body wall of the 5th instar larvae of silkworm,Bombyx mori. Two kinds of protein samples were obtained from the body wall using the method. Between the two types of samples only about
15% proteins were identical; the majority were different, indicating that more species of proteins could be obtained with
the sequential extraction method; which will be useful for preparation of protein samples for proteome study. 相似文献

The economic importance of silkworm has moved biologists to explore various intricate mechanisms of the action of vertebrate hormones. The dietary administration of several vertebrate hormones and prostaglandins enhanced both developmental and metabolic processes of silkworm, Bombyx mori L. The main objective of sericulture research is to apply the results to achieve superior quality silk and greater output, to apply lab findings to achieve desirable ecenomic results. 相似文献

Based on bioinformatic analysis, we selected two novel microRNAs (miRNAs), bmo-miR-0001 and bmomiR-0015, from high-throughput sequencing of the Bombyx mori larval posterior silk gland (PSG). Firstly, we examined the expression of bmo-miR-0001 and bmo-miR-0015 in 12 different tissues of the 5th instar Day-3 larvae of the silkworm. The results showed that the expression levels of both bmo-miR-0001 and bmo-miR-0015 were obviously higher in the PSG than in other tissues, implying there is a spatio-temporal condition for bmo-miR-0001 and bmo-miR-0015 to regulate the expression of BmFib-L. To test this hypothesis, we constructed pri-bmo-miR-0001 expressing the plasmid pcDNA3.0 [ie1-egfp-pri-bmo-miR-0001-SV40] and pri-bmo-miR-0015 expressing the plasmid pcDNA3.0 [ie1-egfp-pribmo-miR-0015-SV40]. Finally, the BmN cells were harvested and luciferase activity was detected. The results showed that luciferase activity was reduced significantly (P<0.05) in BmN cells co-transfected by pcDNA3.0 [ie1-egfp-pri-bmomiR-0001-SV40] or pcDNA3.0 [ie1-egfp-pri-bmo-miR-0015-SV40] with pGL3.0 [A3-luc-Fib-L-3′UTR-SV40], suggesting that both bmo-miR-0001 and bmo-miR-0015 can down-regulate the expression of BmFib-L in vitro. 相似文献

谷胱甘肽S-转移酶（glutathione S-transferases ,GSTs）在昆虫代谢各种内源和外源性有害化合物的过程中起关键作用。重要水稻害虫稻纵卷叶螟（Cnaphalocrocis medinalis）的GST基因目前尚无研究。本实验克隆了一个稻纵卷叶螟delta家族GST基因的全长cDNA序列,命名为CmGSTd3（Genbank登录号KM433686）。CmGSTd3包含681 bp的开放阅读框,编码一个由226个氨基酸组成的蛋白。CmGSTd3蛋白是一个胞质GST ,与已知的昆虫delta家族GST 具有较高的同源性。在系统进化分析中,CmGSTd3与家蚕的delta家族GST聚在同一进化分支上。实时荧光定量PCR结果显示,CmGSTd3基因在稻纵卷叶螟幼虫阶段表达量最高,且主要表达于幼虫的中肠和脂肪体,由此推测其可能参与了体内异源毒物的代谢。本研究为探索CmGSTd3的生理功能奠定了前期基础。 相似文献

昆虫杆状病毒在生物技术研究中的应用 总被引：2，自引：0，他引：2
随着昆虫杆状病毒分子生物学研究的不断深入，昆虫杆状病毒在生物技术研究中也得到了应用。利用杆状病毒作为载体，在昆虫细胞和虫体内表达外源基因，形成了昆虫杆状病毒载体表达系统，利用杆状病毒携带外源基因，通过同源重组将外源基因导入到家蚕的基因组构建了转基因家蚕；通过向杆状病毒基因组中插入毒素、激素、酶抑制剂等的基因或从杆状病毒基因组中删除某个基因，或通过不同杆状病毒间的杂交，使子代病毒的宿主域扩大，从而提高了杆状病毒作为生物杀虫剂的杀虫效果。本文对杆状病毒在上述几个方面的应用进行了简要综述。 相似文献

美国经济学界在竞争理论研究中很早就开始重视竞争与效率,创新的关系,但直到20世纪90年代,美国政府才真正推动创新作为反托拉斯的政策目标,并在处理企业合并时引入新的分析方法,保证反托拉斯为推动创新服务。这种政策转变,虽然客观上造成了放松限制企业合并行为的情况,但并不意味着美国政府在反托拉斯政策向上日本和欧洲靠扰,而是有效地促使企业竞争更多地在创新领域中展开,直接推动了美国新经济的发展。 相似文献

The bioactivity of the aqueous extracts of the leaf and stem bark of the medicinal plant, Alstonia boonei De Wild (Apocyanaceae), against the pink stalk borer, Sesamia calamistis Hampson (Lepidoptera: Noctuidae) was studied in a laboratory bioassay. The extracts were incorporated into artificial diet at a rate of 0.0% (control), 1.0%, 2.5%, 5.0%, and 10.0% (w/w). Both extracts significantly (P<0.01) reduced larval survival and weight in a dose dependent manner. The concentrations that killed 50% of the larvae (LC50) for the stem bark extract were 2.8% and 2.1% at 10 and 20 DAI (days after introduction), respectively, while those for the leaves extract were 5.6% and 3.5%. The weights of the larvae also varied significantly (P<0.05) between the treatments in a dose dependent manner. We conclude that both leaf and stem bark extracts of A. boonei are toxic, used as growth inhibitors to S. calamistis larvae, and hold good promise for use as alternative crop protectants against S. calamistis. 相似文献
