Brief biography: I focused on the molecular mechanism research and breeding application of important functional genes for low phosphorus (LP) tolerance in soybean, since I studied at Henan Agricultural University and supervised by professor Dan Zhang in 2020. In this paper, combining with transcriptome analysis, spatio-temporal expression pattern analysis, haplotype analysis and domestication analysis, we found that GmERF1 was a key candidate gene related to phosphorus efficiency. Functional analysis showed that GmERF1 could regulate soybean root architecture and tolerance to LP stress by mediating ethylene content in roots of transgenic plants. Further analysis identified GmERF1 and GmWRKY6 interact with each other and jointly inhibit the expression of a series of downstream target genes such as GmPHT1s in the phosphorus metabolic pathway. Our study not only provides a new gene resource for efficient molecular breeding of soybean phosphorus, but also provides a reference model for plant adaptation to LP stress.

个人简介：于2020年加入河南农业大学农学院张丹教授课题组，研究方向主要集中在大豆耐低磷重要功能基因的分子机制研究及育种应用。本研究结合转录组分析、时空表达模式分析、单倍型分析及驯化分析表明，GmERF1是一个与磷效率相关的关键候选基因；功能分析表明该基因能够通过调节转基因植株根系的乙烯含量进而调控大豆根系构型以及对低磷胁迫的耐受性；进一步分析发现GmERF1和GmWRKY6存在相互作用且共同抑制磷代谢途径中GmPHT1s等下游一系列靶基因的表达。我们的研究不仅为大豆磷高效分子育种提供了新的基因资源，而且为植物响应低磷胁迫的适应机制提供了一个参考模型。
