Recently, the research team led by Prof. Xiang Yun from the School of Life Sciences made breakthroughs in the study of sexual reproduction of angiosperms.
1. The team discovered new mechanism of angiosperm pollen germination adaptation to high temperature.
On November 6, Prof. Xiang Yun’s team published an article entitled “Evolution of the thermostability of actin-depolymerizing factors enhances the adaptation of pollen germination to high temperature” (DOI:10.1093/plcell/koad280) in the journal The Plant Cell.
Young research fellow Qian Dong, doctoral students Li Tian and Chen Shuyuan are co-first authors, and Prof. Xiang Yun is the correspondent author. Prof. He Yongxing, Prof. Wan Dongshi, post-doctor Yang Yang, associate Prof. Niu Yue, Prof. An Lizhe from LZU and Prof. Li Jiejie from Beijing Normal University (BNU) participated in the work.
2. The team found the new mechanism for regulating the integrity of pollen tubes.
On October 28, the team published a research paper entitled “The Arabidopsis GPI-anchored protein COBL11 is necessary for regulating pollen tube integrity” (doi: 10.1016/J. Celrep.20033) in the journal Cell Reports.
Doctoral student Li Hongxia and post-doctor Yang Yang are co-first authors, and Prof. Xiang Yun is the corresponding author. Prof. Ren Haiyun and assistant research fellow Du Pingzhou from BNU, young research fellow Qian Dong, associate Prof. Niu Yue and Prof. An Lizhe from LZU participated in the research.
3. The team revealed the molecular mechanism of maintaining pollen tube width.
On March 23, the team published an article entitled “SEC1A and SEC6 synergistically regulate pollen tube polar growth” (DOI:10.1111/jipb.13486) in Journal of Integrative Plant Biology.
Doctoral students Fan Tingting and Fan Yuemin are co-first authors, and Prof. Xiang Yun is the correspondent author. Young research fellow Qian Dong, associate Prof. Niu Yue and Prof. An Lizhe participated in the research.
The above 3 studies are supported by the National Natural Science Foundation of China, the Fundamental Research Funds for the Central Universities of LZU and the Yazhou Bay Seed Laboratory, Hainan Province.
