One hundred and sixty crabs(average initial weight:51.32±0.08 g)were fed with four experimental diets containing cottonseed meal protein hydrolysate(CPH)at 0%(CPH0,control),0.3%(CPH0.3),0.6%(CPH0.6),and 1.2%CPH(CPH1.2).The experiment results show that no difference was observed in specific growth rate and survival rate of crabs fed with CPH *** content of crabs fed with CPH0.6 diet was significantly reduced than that of the CPH0 *** dismutase and catalase activities of crabs fed with CPH0.6 diet were significantly increased and the difference was not significant between the CPH0.3 and CPH0.6 *** content of CPH0.3 group was significantly lower than that of the CPH0 ***,alkaline phosphatase,and acid phosphatase activities of CPH0.3 diet crabs were significantly higher than that of the CPH0 ***-pyruvic transaminase activity of crabs fed with CPH0.3 diet was significantly decreased compared to the CPH0 *** relative expression levels of Toll1,Toll2,MyD88,LITAF,and ILF-2 of crabs fed with CPH0.3 diet were significantly higher than that of the CPH0 *** expression level of SOCS2 showed an opposite *** CPH perfusion,the expression levels of SOCS2 and Toll1 in intestine at time 3 h and SOCS2 in hepatopancreas at time 18 h increased significantly to the highest *** expression level of Toll2,MyD88,LITAF,decreased at times 6 h,6 h,12 h,respectively,then increased ***,supplementation of dietary CPH could improve antioxidant capacity and immune function;the appropriate supplement dosage of CPH for crab could be 0.3%-0.6%.Furthermore,the short-term CPH stimulation could significantly increase or decline the expression levels of immune-related genes at different times after CPH perfusion.

Biogenic volatile organic compounds(BVOCs)are widely involved in a variety of atmospheric chemical processes due to their high reactivity and species *** date,however,research on BVOCs in agroecosystems,particularly fruit trees,remains scarce despite their large cultivation area and economic *** emissions from different organs(leaf or fruit)of apple and peach trees were investigated throughout the stages of fruit development(FS,fruit swelling;FC,fruit coloration;FM,fruit maturity;and FP,fruit postharvest)using a proton-transfer-reaction mass *** indicated that methanol was the most abundant compound emitted by the leaf(apple tree leaf 492.5±47.9 ng/(g·hr),peach tree leaf 938.8±154.5 ng/(g·hr)),followed by acetic acid and green leaf *** the above three compounds,acetaldehyde had an important contribution to the emissions from the ***,the total BVOCs(sum of eight compounds studied in this paper)emitted by both leaf and fruit gradually decreased along the fruit development,although the effect was significant only for the *** leaf(2020.8±258.8 ng/(g·hr))was a stronger BVOC emitter than the fruit(146.0±45.7 ng/(g·hr))(P=0.006),and there were no significant differences in total BVOC emission rates between apple and peach *** findings contribute to our understanding on BVOC emissions from different plant organs and provide important insights into the variation of BVOC emissions across different fruit developmental stages.
