Brief bio: I have been trained in cellular biology by Prof. Yan Zhang at Shandong Agricultural University since 2015. My main research projects focus on the molecular mechanisms of ovule development in Arabidopsis. Ovules, the progenitor of seeds, are critical for successful double fertilization. Ovules are composed of sporophytic integument cells and gametophytic embryo sacs. Although it’s been well known that cells of the two generations communicate with each other to ensure synchronized development, the underlying molecular mechanisms are unknown.

In this Plant Physiology paper, we reported that a karyopherin IMPORTIN β4 (IMB4) regulates ovule integument development through nucleocytoplasmic transport of GRF-INTERACTING FACTORS(GIFs). My current research is aimed at a bigger question, how integument-female gametophyte communication is conducted? I hope that my future research not only gives answers to that big question but also provides more meaning to my life.






在Plant Physiology发表的这篇论文中,我们报道了核输入蛋白IMB4通过介导GIFs入核来调控胚珠珠被的发育。而我目前的研究,意在揭示一个更重大的问题,雌配子体珠被及胚囊之间如何进行细胞间的信息交流?我希望自己将来的研究能解决重大问题,让自己变得更有价值,也让自己的生活更有意义。
