Article Synopsis
- - The study investigates a harmful gram-positive bacterium affecting Nile tilapia and aims to uncover genetic traits linked to survival against it by identifying SNPs connected to quantitative trait loci (QTL) related to resistance.
- - Researchers conducted a controlled challenge test on Nile tilapia from a breeding program, analyzing phenotypes and collecting DNA samples for genotyping, which revealed significant SNPs that explain a noteworthy percentage of genetic variance in survival rates.
- - The findings support the application of marker-assisted selection (MAS) in breeding initiatives, as offspring from "resistant" parents showed a mortality rate of less than 1%, compared to 73% for those from "susceptible" parents, indicating effective genetic improvement for resistance. *
