MADS-box蛋白是参与植物生殖发育的关键转录因子。拟南芥APETALA1(AP1)是MIKC型MADS-box基因，在花发育过程中发挥重要作用。在本研究中，我们分离并鉴定了GmAP1，它在大豆中编码一种类似AP1的蛋白。GmAP1由8个外显子和7个内含子组成，在花中特异表达，特别是在花瓣和花瓣中表达。GmAP1是一种核定位转录因子，具有反式激活活性。它在烟草中异地表达时，会导致早花和花器官的变化。据我们所知，这是第一个从大豆中鉴定AP1样基因的报告。(C)2011年爱思唯尔股份有限公司。版权所有。
MADS-box proteins are key transcription factors involved in plant reproductive development. APETALA1 (AP1) in Arabidopsis is a MIKC-type MADS-box gene and plays important roles in flower development. In this research, we isolated and characterized GmAP1, which encoded an AP1-like protein in soybean. GmAP1 contained eight exons and seven introns and was specifically expressed in the flower, especially in the sepal and petal. GmAP1 was a nucleus-localized transcription factor and displayed transactivation activity. It caused early flowering and alteration of floral organs when ectopically expressed in tobacco. To our knowledge, this is the first report characterizing an AP1-like gene from soybean. (C) 2011 Elsevier GmbH. All rights reserved.
