摘要
适时开花对植物的发育和繁殖至关重要。在拟南芥中，开花过程由至少6个独立通路组成的调控网络管理。开花位点T作为开花调控的核心蛋白，几乎参与了上述所有通路。ANKYRIN REPEAT-CONTAINING PROTEIN 2A (AKR2A)最初是作为14-3-3相互作用蛋白被发现的。随后发现它参与叶绿体外膜蛋白的运输和对低温胁迫的抗性。在这里，我们鉴定了一个akr2a零突变体，具有延迟开花表型。通过实时荧光定量PCR (qRT-PCR)和双分子荧光互补(BiFC)分析，我们证实AKR2A通过与FT的相互作用调节开花过程。
AKR2A is involved in the flowering process of Arabidopsis thaliana.
Flowering at an appropriate time is crucial for plant development and reproduction. In Arabidopsis, the flowering process is managed by a regulatory network composed of at least 6 independent pathways. As a core protein in flowering regulation, FLOWERING LOCUS T (FT) participates in almost all these pathways. ANKYRIN REPEAT-CONTAINING PROTEIN 2A (AKR2A) was initially discovered as a 14-3-3-interacting protein. It was then found to be involved in the transportation of chloroplast outer membrane proteins and the resistance to low-temperature stress. Here, we identified an akr2a null mutant with a delayed flowering phenotype. Through the quantitative real-time PCR (qRT-PCR) and bimolecular fluorescence complementation (BiFC) assays, we demonstrated that AKR2A modulates the flowering process through its interaction with FT.
