Brief Bio: After graduating with a Ph.D. degree in 2010 from Iowa State University, I returned to China and joined College of Life Sciences at Northwest A&F University. In activation-tagging screens, I found an Arabidopsis mutant with an elongated cotyledon phenotype. The study of this mutant has brought me to a whole new world of plant cytoskeleton research. Prior to this, my work focused primarily on the mechanism of chloroplast development, and cytoskeleton was a completely unknown field to me. Changing the direction of research has never been an easy task, but when I first saw the fluorescent microtubules in living plant cells under the microscope, the magic and beauty of them captured my heart and made me feel that all the effort was worth it. The dynamic behavior of microtubules is regulated by various types of microtubule-associated proteins (MAPs) and is key to the functions of microtubules, and plant growth and development. At present, the functional interaction networks of plant MAPs is still not fully understood. The MAP215 family MT polymerase/nucleation factor and the MT severing enzyme katanin are two widely conserved MAPs. Our work discovered genetic, molecular, and functional interactions between MOR1, the Arabidopsis MAP215 homolog, and KTN1, the catalytic subunit of katanin, in regulating MT dynamics, cell morphogenesis, and cell division in Arabidopsis, providing a glimpse into the functional interaction networks of plant MAPs.
