　　团队研究方向

　　课题组关注植物生物多样性基因组，聚焦于禾本科与豆科，以及背后两个关键的科学问题：结瘤共生固氮与C4高光效的分子机制，并致力于从“phylogenomics”、“population genetics”和“trait-based ENCODE”三个维度进行系统研究。愿景是学习大自然与进化的智慧并应用于农业与食品领域。主要研究方向包括：

　　1. 结瘤共生固氮演化起源与遗传调控网络构建；

　　2. C4/CAM高光效性状平行演化的分子机制；

　　3. 禾本科谷物与豆科豆类作物群体基因组及基因发现(G3RP: Global Grain Genomics Research Program);

　　研究进展

　　运用大规模比较系统发育基因组学技术分析结瘤固氮的祖先起源、分布和多样性形成机制，首次提出“多重独立丢失”学说，为结瘤固氮遗传调控网络构建、结瘤固氮功能基因组学和将以豆科为代表的结瘤固氮性状通过工程化手段移植到非豆科作物中奠定了坚实的理论基础；通过基因组测序和生物信息学分析手段，研究禾本科、豆科等生物多样性丰富的植物科属及其代表性物种，探索其基因组进化历史和祖先重构，关键基因家族演化史，非编码区调控元件及关键遗传代谢通路网络构建；积累大量有关真核生物的起源、陆地植物、植物、微生物symbiosis的起源等关键进化节化点上的基因组数据和发现。文章先后发表在 Science ， Cell ， Nature , Nature Genetics ， Plant Cell ， Plant Journal 等知名学术刊物中。

　　

　　PI

　　Shifeng CHENG, professor, doctoral advisor. “Outstanding Young Talent” of CAAS, winner of National Excellent Youth Fund, national leading talent at Shenzhen.

　　His main research interest is “how plant acquired new traits, and how crop evolved with phenotypic changes”, either by comparative & evolutionary genomics (phylogenomics) in plant long evolutionary history, or by population genomics in species level. In the past a few of years, his team has been focusing on the molecular mechanism underlying the origin and diversification of Nitrogen-fixing root nodule symbiosis, C4 photosynthesis, plant macroevolution, as well as the domestication history and key trait evolution in the two most important crop clade: cereal and legume. He is leading the “Global Grain Genomics Research Program”: G3RP, http://g3rp.com/, to decode the global grain crop wild relatives from three dimensions: (1) phylogenomics; (2) population genetics; (3) trait-based ENCODE (multi-omics), and utilize genomics-based big data to guide precise agriculture. Achievements have been made to unravel the genomic novelties and master regulators that were responsible for root nodule symbiosis (NIN genes), and plant terrestrialization (GRAS gene family). These results were published as leading author in Science , Cell , Nature Biotechnology , and Plant Cell , etc., mostly were selected to Faculty 1000.

　　Research Interest

　　His team focuses on plant biodiversity and evolutionary genomics, particularly on large-scale phylogenomics both for cereal grains and legume grains, in which two key scientific questions are highlighted: N-fixing root nodule symbiosis and C4 photosynthesis. The vision is: borrow genes from nature, evolution, and biodiversity to ‘real crops’. Current research topics include:

　　1. Origin and evolutionary genetic pathway of N-fixing root nodule symbiosis;

　　2. large-scale phylogenomics and the underlying molecular mechanism of the parallel evolution of C4 photosynthesis;

　　3. G3RP: Global Grain Genomics Research Program, an international consortia；

　　4. horizontal gene transfer and plant macroevolution.

　　

　　Major Achievements

　　Through large-scale phylogenomics study, his team explores the genome evolution and diversity of Root Nodule Symbiosis across N-fixing Nodulation Clade, proposed a “multiple independent losses” hypothesis to explain the underlying mechanism of the "deep homology and phylogenetic distribution" for RNS in NFN clade, the results was published in Science (Science 2018, DOI: 10.1126/science.aat1743), a series of follow-up studies are still ongoing. Meanwhile, by collaborating with Michael Melkonian and the 10KP team, they identified two key genes, which were transferred from soil bacterial to the ancestor of land plants at around 550 milliion years ago, playing key role in plant terrestrialization and adaptation process. This result was published in Cell (Cell, 2019, DOI: https://doi.org/10.1016/j.cell.2019.10.019). They are still exploring the molecular mechanism of primary endosymbiosis 1.5 billion years ago, the gradual loss and gains (kleptoplastid) responsible for the horizontal spread of photosynthesis among many ocean algae and protists. Recently, they initiated the G3RP program, to call for global effort to have a systematic study on both cereal grains and legume grain genomes.
