Pineapple (.) cultivation commonly relies on asexual reproduction which is easily impeded by many factors in agriculture production. Sexual reproduction might be a novel approach to improve the pineapple planting. However, genes controlling pineapple sexual reproduction are still remain elusive. In different organisms a conserved superfamily proteins known as ATP binding cassette (ABC) participate in various biological processes. Whereas, till today the gene family has not been identified in pineapple. Here 100 genes were identified in the pineapple genome and grouped into eight subfamilies (5 , 20 s, 16 , 2 , one , 5 , 42 and 9 ). Gene expression profiling revealed the dynamic expression pattern of gene family in various tissues and different developmental stages. , , , , and exhibited preferential expression in ovule and stamen. Over-expression of in the double mutant partially restored its pollen abortion defects, indicating that plays important roles in pollen development. Our study on gene family in pineapple provides useful information for developing sexual pineapple plantation which could be utilized to improve pineapple agricultural production.
菠萝（.）种植通常依赖无性繁殖，而无性繁殖在农业生产中容易受到多种因素的阻碍。有性繁殖可能是一种改良菠萝种植的新方法。然而，控制菠萝有性繁殖的基因仍然难以捉摸。在不同生物中，一种被称为ATP结合盒（ABC）的保守超家族蛋白参与各种生物过程。然而，迄今为止，菠萝中尚未鉴定出该基因家族。在此，在菠萝基因组中鉴定出100个基因，并将其分为八个亚家族（5个、20个、16个、2个、1个、5个、42个和9个）。基因表达谱揭示了该基因家族在各种组织和不同发育阶段的动态表达模式。、、、、和在胚珠和雄蕊中表现出优先表达。在双突变体中过表达部分恢复了其花粉败育缺陷，表明在花粉发育中起重要作用。我们对菠萝基因家族的研究为开发有性菠萝种植园提供了有用信息，可用于提高菠萝农业产量。
