In order to reveal the mechanism of flower development and provide a theoretical basis for solving the problems of flowering in the sugar apple industry, the Auxin Response Factor (ARF) family genes were identified and the expression patterns were analyzed. Based on transcriptome sequencing, 11 AsARF genes were selected and identified. The biological functions of AsARF family genes were preliminarily analyzed by homologous evolution analysis, protein domain analysis, subcellular localization, qRT-PCR, and other techniques. The AsARFs were divided into five classes based on phylogenetic analysis. The proteins had molecular weight varying from 73.85 to 112.51 kDa and isoelectric point from 5.42 to 7.63. All the AsARFs contained two domains of DBD and MR, and, except for AsARF3a, 6a and 6b, they also all contained a CTD domain. Subcellular location prediction results showed that the AsARF members were mainly located in the nucleus. Based on amino acid enrichment in the intermediate region of the protein, AsARF5a, AsARF5b, AsARF6c, AsARF6d, AsARF7 and AsARF16 were speculated to be transcriptional activators, while AsARF2, AsARF3a, AsARF3b, AsARF6a and AsARF6b were presumed to be transcriptional repressors. Three CTD domain-deleted ARF genes were identified and they may have unique biological functions. The results of subcellular location experiments showed that AsARF2, AsARF3a and AsARF6a were localized in the cell nucleus. Real-time quantitative PCR results showed that AsARF3a, AsARF3b, AsARF5a, AsARF5b, AsARF6a and AsARF7 genes were expressed more in the inflorescent meristem. AsARF2 and AsARF6b genes were highly expressed in flower buds. AsARF2, AsARF3a, AsARF5a, AsARF5b, AsARF6b, AsARF6c and AsARF16 genes were predominantly expressed in normal flowers, while the expression of AsARF3b, AsARF6a, AsARF6d and AsARF7 genes in malformed flowers was greater than that in normal flowers. These results suggest that AsARF may play key roles in regulating the flower development in sugar apple. The high expression of AsARF6b and AsARF6c in normal flowers and AsARF6a and AsARF6d in abnormal flowers indicate that they play important roles in the normal development of flowers.

鉴定番荔枝ARF家族基因,并分析其在花发育中的表达谱,为深入探索ARF家族基因调控花发育的机制奠定基础,为解决番荔枝产业上出现的“花而不实”、结果率低等问题提供理论依据。以番荔枝为研究对象,基于转录组测序,筛选鉴定出11个番荔枝AsARF基因。通过同源进化分析、蛋白结构域分析、亚细胞定位、qRT-PCR等技术,初步分析了AsARF家族基因的生物学功能。进化树分析结果显示,AsARF蛋白可以被分为5组。AsARF的预测蛋白分子量在73.85~112.51 kDa之间,等电点分布于5.42~7.63之间。所有AsARF蛋白均含有1个DNA结合结构域和1个中间区域结构域,除AsARF3a、AsARF6a和AsARF6b外,其他蛋白还存在1个C-末端二聚化结构域。基于蛋白中间区域的氨基酸富集情况,推测AsARF5a、AsARF5b、AsARF6c、AsARF6d、AsARF7和AsARF16这6个蛋白可能为转录激活子,而AsARF2、AsARF3a、AsARF3b、AsARF6a和AsARF6b这5个蛋白推测为转录抑制子。鉴定得到3个CTD结构域缺失的ARF基因:AsARF3aAsARF6aAsARF6b,它们可能有着独特的生物学功能。亚细胞定位预测结果显示,AsARF蛋白主要定位在细胞核中。亚细胞定位实验结果显示,AsARF2、AsARF3a和AsARF6a蛋白定位于细胞核,表明AsARF蛋白具有转录因子的核定位特征。qRT-PCR结果显示,AsARF3aAsARF3bAsARF5aAsARF5bAsARF6aAsARF7在花芽期表达量最高,AsARF2AsARF6b的表达量在花蕾期最高。AsARF2AsARF3aAsARF5aAsARF5bAsARF6bAsARF6cAsARF16基因在正常花中的呈现高表达,而AsARF3bAsARF6aAsARF6dAsARF7则在畸形花中表达量更高。AsARF6bAsARF6c在正常花中表达量高、而AsARF6aAsARF6d在畸形花中表达量更高,说明它们在花的正常发育中起到了重要作用。

鉴定番荔枝ARF家族基因,并分析其在花发育中的表达谱,为深入探索ARF家族基因调控花发育的机制奠定基础,为解决番荔枝产业上出现的“花而不实”、结果率低等问题提供理论依据。以番荔枝为研究对象,基于转录组测序,筛选鉴定出11个番荔枝AsARF基因。通过同源进化分析、蛋白结构域分析、亚细胞定位、qRT-PCR等技术,初步分析了AsARF家族基因的生物学功能。进化树分析结果显示,AsARF蛋白可以被分为5组。AsARF的预测蛋白分子量在73.85~112.51 kDa之间,等电点分布于5.42~7.63之间。所有AsARF蛋白均含有1个DNA结合结构域和1个中间区域结构域,除AsARF3a、AsARF6a和AsARF6b外,其他蛋白还存在1个C-末端二聚化结构域。基于蛋白中间区域的氨基酸富集情况,推测AsARF5a、AsARF5b、AsARF6c、AsARF6d、AsARF7和AsARF16这6个蛋白可能为转录激活子,而AsARF2、AsARF3a、AsARF3b、AsARF6a和AsARF6b这5个蛋白推测为转录抑制子。鉴定得到3个CTD结构域缺失的ARF基因:AsARF3aAsARF6aAsARF6b,它们可能有着独特的生物学功能。亚细胞定位预测结果显示,AsARF蛋白主要定位在细胞核中。亚细胞定位实验结果显示,AsARF2、AsARF3a和AsARF6a蛋白定位于细胞核,表明AsARF蛋白具有转录因子的核定位特征。qRT-PCR结果显示,AsARF3aAsARF3bAsARF5aAsARF5bAsARF6aAsARF7在花芽期表达量最高,AsARF2AsARF6b的表达量在花蕾期最高。AsARF2AsARF3aAsARF5aAsARF5bAsARF6bAsARF6cAsARF16基因在正常花中的呈现高表达,而AsARF3bAsARF6aAsARF6dAsARF7则在畸形花中表达量更高。AsARF6bAsARF6c在正常花中表达量高、而AsARF6aAsARF6d在畸形花中表达量更高,说明它们在花的正常发育中起到了重要作用。

In order to reveal the mechanism of flower development and provide a theoretical basis for solving the problems of flowering in the sugar apple industry, the Auxin Response Factor (ARF) family genes were identified and the expression patterns were analyzed. Based on transcriptome sequencing, 11 AsARF genes were selected and identified. The biological functions of AsARF family genes were preliminarily analyzed by homologous evolution analysis, protein domain analysis, subcellular localization, qRT-PCR, and other techniques. The AsARFs were divided into five classes based on phylogenetic analysis. The proteins had molecular weight varying from 73.85 to 112.51 kDa and isoelectric point from 5.42 to 7.63. All the AsARFs contained two domains of DBD and MR, and, except for AsARF3a, 6a and 6b, they also all contained a CTD domain. Subcellular location prediction results showed that the AsARF members were mainly located in the nucleus. Based on amino acid enrichment in the intermediate region of the protein, AsARF5a, AsARF5b, AsARF6c, AsARF6d, AsARF7 and AsARF16 were speculated to be transcriptional activators, while AsARF2, AsARF3a, AsARF3b, AsARF6a and AsARF6b were presumed to be transcriptional repressors. Three CTD domain-deleted ARF genes were identified and they may have unique biological functions. The results of subcellular location experiments showed that AsARF2, AsARF3a and AsARF6a were localized in the cell nucleus. Real-time quantitative PCR results showed that AsARF3a, AsARF3b, AsARF5a, AsARF5b, AsARF6a and AsARF7 genes were expressed more in the inflorescent meristem. AsARF2 and AsARF6b genes were highly expressed in flower buds. AsARF2, AsARF3a, AsARF5a, AsARF5b, AsARF6b, AsARF6c and AsARF16 genes were predominantly expressed in normal flowers, while the expression of AsARF3b, AsARF6a, AsARF6d and AsARF7 genes in malformed flowers was greater than that in normal flowers. These results suggest that AsARF may play key roles in regulating the flower development in sugar apple. The high expression of AsARF6b and AsARF6c in normal flowers and AsARF6a and AsARF6d in abnormal flowers indicate that they play important roles in the normal development of flowers.
