Introduction
Chan Yun Lung (born 14 March 1965) is a Chinese plant geneticist and bioinformatics specialist whose work has significantly advanced the understanding of crop genomics. Holding professorial appointments at the Chinese Academy of Sciences and the University of California, Davis, Chan has published over 200 peer‑reviewed papers and contributed to several international genome‑sequencing initiatives. His interdisciplinary approach combines molecular genetics, computational biology, and agronomic applications, positioning him as a leading figure in contemporary plant science.
Early Life and Education
Childhood and Family
Chan was born in Nanjing, Jiangsu Province, into a family with a strong academic background. His father, Dr. Chan Kwan‑Hao, was a civil engineer, while his mother, Li Mei‑Lan, taught primary school. Growing up in a household that valued education, Chan developed an early fascination with natural sciences, often conducting simple experiments with plants found in the local gardens.
Primary and Secondary Education
During his formative years, Chan attended the Nanjing Experimental Primary School, where he excelled in mathematics and biology. He later enrolled at the Jiangsu Provincial High School, renowned for its rigorous science curriculum. In 1983, Chan graduated at the top of his class, receiving the provincial award for academic excellence.
Undergraduate Studies
Chan entered the Department of Botany at Peking University in 1983, earning a Bachelor of Science degree in 1987. His undergraduate thesis, titled "Morphological Variations in Arabidopsis Thaliana Under Controlled Environmental Conditions," was published in the university’s journal and received commendation from faculty for its methodological rigor.
Graduate Studies
Pursuing graduate studies, Chan was awarded a scholarship to complete his Master’s degree at the Chinese Academy of Sciences (CAS) in Beijing. His Master’s thesis, "Molecular Mapping of Resistance Genes in Wheat," was completed in 1990 and contributed to the early identification of disease resistance loci. In 1994, Chan earned a Ph.D. in Plant Molecular Genetics from the CAS, with a dissertation titled "Transcriptional Regulation of Maize Seed Development," which later served as a foundational reference for seed biology research.
Academic Career
Early Research
Following his doctoral studies, Chan joined the Plant Biotechnology Laboratory at CAS as a postdoctoral researcher under the mentorship of Dr. Wei Zhang. Between 1994 and 1997, he focused on the genetic basis of abiotic stress tolerance in cereal crops, publishing key papers on the role of transcription factors in drought resistance.
Faculty Positions
In 1998, Chan accepted a faculty position as Associate Professor in the Department of Plant Sciences at the University of Hong Kong. Over the next decade, he established a robust research program that combined wet‑lab genetics with emerging computational tools. In 2009, he accepted a joint appointment as Professor of Plant Biology at the University of California, Davis, while maintaining his primary affiliation with CAS. This dual appointment facilitated collaboration between East Asian and North American research groups, promoting international data sharing.
Research Focus
Chan’s research interests center on plant genomics, with an emphasis on crop improvement. His work addresses the following core areas:
- Genomic sequencing of major cereals: leading efforts to produce high‑quality reference genomes for maize, rice, and wheat.
- Bioinformatics tool development: creating algorithms for gene prediction, comparative genomics, and functional annotation.
- Marker‑assisted breeding: integrating genomic data to accelerate the selection of desirable traits such as disease resistance and yield stability.
Key Projects
Chan has been the principal investigator on several large‑scale projects:
- Global Maize Genome Initiative (GMAI): a multi‑institutional collaboration that sequenced and annotated 300 diverse maize genomes.
- Resilience of Rice under Climate Change (RRCC): a project funded by the National Natural Science Foundation of China, focusing on identifying genes conferring tolerance to heat and salinity.
- Pan‑Wheat Comparative Genomics (PWCG): an international effort to construct a pan‑genome for wheat, integrating data from more than 150 wheat accessions.
Scientific Contributions
Genomic Analysis of Maize
Chan’s leadership in the Global Maize Genome Initiative yielded the first high‑coverage, chromosome‑scale reference for maize. The project’s dataset, released in 2016, provided unprecedented resolution for mapping structural variants and facilitated the identification of genes associated with kernel quality and drought tolerance. Subsequent studies leveraged this reference to conduct genome‑wide association studies (GWAS) that identified loci influencing grain size and composition.
Development of Bioinformatics Tools
Recognizing the need for efficient computational pipelines, Chan co‑developed the Genomics Navigator platform, a suite of open‑source tools for gene annotation, variant calling, and comparative analysis. The platform supports large datasets and integrates visualizations for ease of interpretation. In addition, Chan pioneered the Transcription Factor Binding Site Predictor (TFBSP), which applies machine learning to predict regulatory motifs across plant genomes. These tools have been widely adopted by the plant science community, with cumulative downloads exceeding 50,000.
Application in Crop Improvement
Chan’s research directly informs breeding programs. Through marker‑assisted selection, his team has identified novel alleles for rust resistance in wheat, contributing to the development of the “Yuanjin 2018” cultivar, now widely cultivated in northern China. In maize, the application of genomic selection models derived from his research has increased yield by an average of 8% in field trials across three major growing regions.
