中文摘要：

以拟南芥酰基载体蛋白为查询序列,检索18个植物物种的基因组数据库,获得138个酰基载体蛋白基因和12个基因片段。植物酰基载体蛋白由1个基因家族编码,成员2～16个。植物酰基载体蛋白磷酸泛酰巯基乙胺结合位点（Ser）周围的氨基酸序列高度保守,该位点包含在保守的DSL基序中。植物酰基载体蛋白基因结构类型分为5种,其中类型III酰基载体蛋白基因所占比例最大。绝大多数植物酰基载体蛋白基因家族成员单独或2～4个成员分布在一条染色体上。在138个植物酰基载体蛋白基因中,19个具有不同剪接体。植物酰基载体蛋白基因家族成员可能起源于一个共同的祖先基因。

英文摘要：

Blasting target genome database of 18 plant species using eight A.thaliana acyl carrier proteins（ACPs） as queries,138 ACP cDNA sequences and 12 ACP fragments were isolated.Plant ACPs were encoded by one gene family including 2-16 members.The amino acid sequence surrounding the phosphopantetheine attachment sites（Ser） within the DSL motif was highly conserved in plant ACPs.Gene organization of plant ACPs can be grouped into five types and the type III was in the largest proportion.One or 2-4 members of ACP families were located on one chromosome in most plant genomes.Nineteen ACP genes can produce splicing variants in 138 plant ACPs.Plant ACP isoforms may be originated from one ancestral ACP gene.
