ABC转运蛋白在植物花器官生长发育中的研究进展

ABC转运蛋白(ATP binding cassette transporter) 是目前发现的最大的蛋白家族之一，其广泛存在于真核生物与原核生物之中，近年来在植物研究领域正受到越来越多的关注。ABC转运蛋白的转运底物种类较为多样，该家族成员几乎作用于植物生长发育的各个阶段，并对植物花器官产生较大的影响。该文对ABC转运蛋白的基本特征及亚家族分类情况进行了总结，重点对近年来国内外有关ABC转运蛋白家族在植物花药和花序轴等花器官生长发育，以及花瓣形态、花色、花香等观赏性状方面的调控功能等方面的研究进展进行了综述，并对ABC转运蛋白在改良植物花色、花香等观赏性状方面的应用潜力进行展望，以期为植物观赏性状的改良提供一定的参考。

Recent Progress of ABC Transporters in Floral Organ Development of Plants

ABC transporter (ATP binding cassette transporter) is one of the largest protein families. It is widely found in eukaryotes and prokaryotes, and has attracted more and more attention in plant field in recent years. As the transportable substrates of ABC transporters are diverse, they can widely participate in the developmental processes of plant. Meanwhile, ABC transporters also have great effects in the growth of plant flower organs and the formation of ornamental characteristics of plants. In this study, the characteristics and subfamily classification of ABC transporters were summarized. In addition, the functions of ABC transporter family in the growth of flower organs and their ornamental characteristics were highlighted. The potential application of ABC transporters in improving plant ornamental traits was also explored, which could supply useful strategies for improving the plant ornamental traits.
