Complete Genome Sequence Analysis of MC4-2 Strain That against Tobacco Black Shank Disease.

The MC4-2 bacterium strain was isolated and purified from the intestine as a biocontrol agent with good antagonistic effect against the pathogens of a soil-borne disease called tobacco black shank. The MC4-2 strain was found to have good broad-spectrum inhibition by plate stand-off test. Based on 16S rRNA and genes, ANI analysis, and other comparative genomics methods, it was determined that the MC4-2 strain was .

Bio-accumulation effects of heavy metals Pb, Zn and Cd on parasitism to at Suzu metal mines, Yunnan.

is an obligatory parasitic insect to . Both organisms have been spread to some metal mines areas. The objective of this study is to comprehend the trend of heavy metals transfer and the process of their bio-accumulation in the soil-- system and particularly their impact on the parasitic effect of to to reflect the impact of heavy metals on obligate parasitic insect and its host.
