Main work
Dr. Zhang Bingyu has been engaged in the genetic improvement of poplar trees over 20 years. She has led 5 national research projects, won the first and second prize of Liangxi Awards, obtained 4 national invention patents as well as 3 new transgenic poplar variety rights, published over 50 research papers in journals within or outside China. The main results in academic research in recent years are as follows:
The genomic structural variations and molecular evolutionary mechanisms of 10 main poplar species belong to five sections of Populus L. were revealed at the genomic level. Through bioinformatics analysis, the genomic structural variations of 10 main tree species belonging to the five Section of Populus L. of China were revealed. The molecular mechanisms underlying the differentiation and evolution of different species in the Populus genus have been revealed, laying the foundation for molecular breeding, genetic map construction, and population diversity research.
Innovatively created a methylation induced transgenic system for poplar trees The key genes of Arabidopsis thaliana methylated (AtMET1) and demethylated (AtDME1) induced by estrogen were introduced into the 84K poplar genome through genetic transformation. The transgenic plant leaves were subjected to estrogen treatment at different times to induce the timed expression of methylated and demethylated genes. Apopulation of poplar methylated variants was obtained, and colorful leaf line, one dwarf line, and more than ten drought and salt resistant lines were further screened.
Three anti-stress new poplar transgenic varieties were developed. Participant in cultivated excellent transgenic varieties of Duokang poplar No.2 and No.3, transgenic drought resistant varieties No.1, No.2, No.3, and No.4, as well as transgenic stress resistant varieties No.1 and No.2. Among them, Duokang poplar No.2, No.3, and stress resistant No.1 have obtained the national new variety protection rights, providing excellent varieties for forestry production and ecological construction in arid and saline alkali areas of China.
