花生FAT基因家族的全基因组分析
Whole-Genome Analysis of Peanut FAT Gene Family
摘要
Abstract
Fatty acyl-ACP thioesterase (FAT)is the key enzyme regulating the synthesis of plant seed oil.According to the amino acid sequence and substrate specificity,FAT is divided into FATA and FATB sub-family.In order to better understand the characteristics of AhFAT gene family,the bioinformatics analysis was carried out.There were 20 AhFAT genes in the peanut genome,which heterogeneously distributed on 12 chro-mosomes in the two genomes.The twenty AhFAT genes could be divided into AhFATA and AhFATB subfamily, which had 2 and 18 members respectively.The AhFATA subfamily owned 6 or 8 exons,and the AhFATB sub-family had complex gene structures with 5 ～8 exons.None of the AhFATs had transmembrane domains,but they all owned the conserved Acyl-ACP＿TE domain.The alternative splicing analysis of AhFAT gene family revealed that only a few AhFATs undergone alternative splicing and they had different splicing types in different tissues.The AhFATs expression pattern analysis results showed that both AhFATAs and AhFATBs expressed at higher levels in the later stage of seed development.关键词
