摘要

选择α -淀粉酶(AMY)和组织蛋白酶- l (CTSL)作为单胞假单胞菌生长性状SNP发现的候选基因。单殖单胞菌在AMY中发现6个snp，在CTSL中发现3个snp。在人群中对候选snp与重要经济性状进行关联分析。CTLS-213 SNP的等位基因A、AA和GA往往与体重增加有关。GG基因型虾的CL、CW和CH值显著低于GT和TT基因型虾(P < 0.05)。CTLS-820 SNP与CH、FSL显著相关(P <0.05)。这些单核苷酸多态性将有效地用于单殖单胞菌的标记辅助选择育种计划。

Association analysis of alpha-amylase (AMY) and cathepsin L (CTSL) SNPs with growth traits in giant tiger shrimp Penaeus monodon

Alpha-amylase (AMY) and cathepsin-L (CTSL) were selected as candidate genes for SNP discovery for growth traits of P. monodon. Six SNPs were found in AMY and three in CTSL in P. monodon. Association analyses for the candidate SNPs with important economic traits were performed in populations. That allele A at CTLS-213 SNP, AA, and GA, tended to be associated with increased body weight. Shrimps with genotype GG had significantly smaller CL, CW, and CH values than those with GT and TT genotypes (P < 0.05). While CTLS-820 SNP was found to be significantly associated with CH and FSL (P <0.05). These SNPs will be valid for marker-assisted selection breeding programs in P. monodon.
