In this study, we investigated the effects of wheat root exudates on soil bacterial communities in watermelon rhizosphere using quantitative PCR and Illumina MiSeq sequencing. The qPCR results showed that significantly increased abundance total bacteria, Pseudomonas, Bacillus Streptomyces spp. sequencing changed community structure composition. These indicated plant play a role plant-to-plant s...

Metallothionein (MT) is important because it binds tightly to heavy metals to decrease their toxicity. DNA was isolated from 30 toxic metal exposed and 30 toxic metal unexposed Zebu cows. The amplified metallothionein isoform-2 (MT-2) PCR product (489 bp) was further used for PCR-RFLP and DNA sequencing. MT-2 TaqI PCR-RFLP revealed homozygous genotype (AA) except for the E23 animal (AB). The ge...

Either PCR-mediated single strand conformation polymorphism (SSCP) analysis or DNA sequencing of rpoB DNA (157 bp) can be used as a rapid screening method for the detection of mutations related to the rifampin resistance of Mycobacterium tuberculosis. However, due to the nonspecific amplification of rpoB DNA from nontuberculous mycobacteria these methods cannot be directly applied to clinical s...
