Project description:Structural differences between the X and X' chromosomes from Bradysia coprophila, and the first assembled model sequence of the ~55 Mb X' long paracentric inversion region
Project description:Hepatic steatosis is the initial manifestation of abnormal liver functions and often leads to liver diseases such as non-alcoholic fatty liver disease in humans and fatty liver syndrome in animals. In this study, we conducted a comprehensive analysis of a large chicken population consisting of 705 adult hens by combining host genome resequencing, liver transcriptome, proteome, and metabolome analysis, as well as microbial 16S rRNA gene sequencing of each gut segment.
Project description:Bradysia odoriphaga and Bradysia difformis are devastating pests of vegetable, ornamental crops and edible mushrooms causing significant losses. Temperature may be an important factor restricting their population abundance in the summer. To determine the effects of short-term heat shock on adults, their survival, longevity and fecundity data were collected, and antioxidant responses and heat shock protein expression levels were examined. Our results indicated that the survival rates of Bradysia adults decreased rapidly after heat shock ≥36 °C, and the longevity and reproductive capacities were significantly inhibited, indicating that short-term heat shock had lethal and sub-lethal effects. Moreover, the lipid peroxidation levels of B. difformis and B. odoriphaga increased dramatically at 36 °C and 38 °C, respectively. Four antioxidant enzymes activities of B. odoriphaga were greater than those of B. difformis at 38 °C. Additionally, hsp70 and hsp90 expression levels significantly increased after heat stress, and higher expression levels of B. difformis and B. odoriphaga were discovered at 36 and 38 °C respectively, indicating their different heat tolerance levels. Overall, short-term heat shock (≥36 °C) caused significantly adverse effects on Bradysia adults, indicating that it could be applied in pest control, and antioxidant system and hsp genes played important roles in their heat tolerance levels.
