The treatment of Bt rice pollen, especially at the concentration of 0.050g/ml, resulted in significantly higher larval mortality, longer developmental time, less body weight of early instar larvae, lower pupation and emergence rate, poorer cocoon quality, lesser number of eggs laid and more number of eggs unlaid per female.
Bt水稻花粉,特别在较高浓度处理下,可导致家蚕幼虫死亡率显著增高、取食量显著减少、发育历期显著延长、低龄幼虫体重明显降低、以及化蛹率、蚕茧质量、羽化率和产卵量等显著下降,而腹中残余卵量显著增高等。

RESULTS: The growth speed, weight, developmental uniformity, bionergy and fecuncity of the Bombyx silkworm descent dramatically as they eat the feed that the concentration of 2,4-DCP over 0.8 mmol L~-1 or NP exceed 0.500 mmol L~-1. But the effect on reproductive capacity vary with gender difference, it's more obvious on the late-stage of development and periods of metamorphosis such as ecolysis, pupation, edosion. There may be cumulative effect inside the Bombyx siliworm.
结果 家蚕幼虫食下含0.8 mmol·L~(-1)以上浓度的2,4-DCP或0.500 mmol·L~(-1)以上浓度的NP饲料,生长速度、生长量、发育整齐度、生命力和生殖能力都明显下降;生殖能力所受影响应性别而不同;家蚕发育后期和蜕皮、化蛹、羽化等变态时期影响更加明显,在蚕体内可能有累积作用。

Our previous studies have shown that ubiquitous overexpression of HmgD caused hemocytes proliferation and the formation of melanotic tumors in the Drosophila larvae. To clarify the mechanism of melanotic tumors appearance,we also generated RT-PCR analysis to test the transcriptional changes of PPAE and Spn27A,which encode the key factors in the phenoloxidasecascade pathway from larvae samples of mid-third instar,late-third instar and prior to pupation relative to wild type flies.Our result showed that in the HmgD overexpression mid-third instar larvae,the expression level.of Spn27A was lower than wild type,otherwise the expression level of PPAE was higher than wild type.It suggests that overexpression of HmgD affects the PO cascade pathway.
本研究组前期工作发现,过量表达HmgD引起果蝇幼虫体内血细胞增生,并出现黑色素瘤,为探讨HmgD过量表达导致了血细胞增生即形成黑色素瘤的分子机制,本研究分别提取三龄中期、后期和相对于野生型化蛹前时刻的幼虫的RNA,首先检测了编码酚氧化酶级联反应途径中的两个关键基因PPAE,Spn27A在突变体中的转录发生变化,结果发现,Spn27A在三龄中期的表达量低于野生型,而PPAE的表达高于野生型,表明过量表达HmgD影响了酚氧化酶级联反应途径,低水平的Spn27A不足以抑制PPAE的活性,活化的PPAE催化了PPO的活性,使其转变成有活性的PO,从而促进黑色素的生成,使果蝇体内产生黑色素瘤。
