Brief bio:
Since 2016, I am working in the Key Laboratory of Molecular Epigenetics of MOE, Northeast Normal University, China, trying to demystify the diverse and amazing volatile terpene synthesis underlying floral scent of horticultural plants.
From 2016 to 2019, I worked with my supervisor Dr. Xiang Gao and co-supervisor Dr. Li Wang characterizing the terpene synthases (TPSs) accounting for the volatilized-terpene heterogeneity in Lathyrus odoratus cultivar flowers. The data has already been published in Plant and Cell Physiology in 2020. Since 2019, I am mainly focusing on Freesia genus. My major work turns to decipher the effects of allelic TPS variations on interspecific terpene diversity under the supervisions of Dr. Xiang Gao and Dr. Yueqing Li. In this study, we characterized a total of 15 TPS genes responsible for floral volatile terpenes of 8 wild Freesia species. Furthermore, we took TPS2, TPS6 and TPS10 as examples to uncover how their alleles controlling terpene synthesis and affecting the terpene diversity among Freesia species. Our results shed light on the genetic basis of floral volatile terpene biosynthesis, dynamic evolution of duplicated TPSs in the Freesia genus, and may contribute to the establishment of ornamental flower varieties with desired fragrances.

个人简介：2016年，我进入东北师范大学分子表观遗传学教育部重点实验室学习，试图解析园艺植物花香之谜。2016年至2019年，在高翔教授和王丽教授的指导下，完成了“决定不同品种香豌豆花朵挥发性萜类化合物异质性的关键萜类合酶（TPSs）”的研究，相关数据已于2020年发表在“Plant and Cell Physiology”杂志。2019年至今，在高翔教授和李月庆副教授的指导下，完成了“萜类合酶（TPSs）等位变异驱动香雪兰属野生种间萜类挥发物多样性”的研究。在这项研究中，我们以8个香雪兰野生种为实验材料，共鉴定了15条TPS基因，此外，我们以TPS2、TPS6和TPS10为例，揭示了它们的等位基因是如何控制香雪兰属萜类的合成并影响其多样性的。研究结果揭示了香雪兰属种间花挥发物多样性的分子基础，在部分代表性野生种间建立了花香味与TPS等位基因变异的关系，本研究结果为野生植物TPS基因的功能多样性和进化提供了全新的视角，此外，功能验证的TPS蛋白和关键氨基酸残基也将有助于培育具有迷人香味的花卉新品种。
