Abstract

Here we describe protein-protein interactions between signaling components in the conserved self-incompatibility pathway from Brassica spp. and Arabidopsis lyrata. Previously, we had demonstrated that ARC1 is necessary in A. lyrata for the rejection of self-pollen by the self-incompatibility pathway. The results described here demonstrate that A. lyrata ARC1 interacts with A. lyrata S Receptor Kinase (SRK1) in the yeast 2-hybrid system. A. lyrata ARC1 also interacted with B. napus SRK910 illustrating that interactions in this pathway are conserved across species. Finally, we discuss how the more widely occurring interactions between SRK and ARC1-related family members may be modulated in vivo by expression and subcellular localization patterns resulting in a particular response.

摘要

在此,我们描述了来自芸苔属植物和琴叶拟南芥的保守自交不亲和途径中信号传导成分之间的蛋白质-蛋白质相互作用。此前,我们已经证明,在琴叶拟南芥中,ARC1对于自交不亲和途径排斥自花花粉是必需的。此处描述的结果表明,在酵母双杂交系统中,琴叶拟南芥ARC1与琴叶拟南芥S受体激酶(SRK1)相互作用。琴叶拟南芥ARC1还与甘蓝型油菜SRK910相互作用,这表明该途径中的相互作用在物种间是保守的。最后,我们讨论了SRK与ARC1相关家族成员之间更广泛存在的相互作用如何在体内通过表达和亚细胞定位模式进行调节,从而产生特定的反应。
