ABSTRACT
Objective To study the antagonistic effects of Ganoderma spore on mutation induced by NaNO2 in Drosophila melanogaster. Methods After 24 hours of starvation,male Drosophila melanogaster were transferred to the culture bottles with medium with NaNO2 of 0,0.001,0.01,0.05 and 0.1 g/L for 24 hours and then cultured with female Drosophila melanogaster for 7 days. Male Drosophila melanogaster were treated with NaNO2 at the doses of 0,0.01,0.001 g/L for 24 hours and then transferred to the medium with Ganoderma spores at the dose of 0.2%,1%,2%,cultured with female Drosophila melanogaster for 7 days. The distilled water was used as the negative control. The amount of F1 generation and the mutation of the F1 generation were calculated. Results The mutation Drosophila melanogaster were mainly vestigial,some had malformation with white body and strange eyes. Compared with the negative control group,the count of offspring decreased,the rate of mutation proved positively correlated to the concentration of NaNO2. High dose of sporoderm-unbroken spores could cause a decrease of number of offspring. Compared with the negative control group,the mutation in the group of 0.1,0.01 g/L NaNO2 with 0.2% sporoderm-unbroken spores was much higher (P
