Emily has successfully defended her dissertation! Congratulations, Dr. Yang! We wish Emily all the best in her postdoctoral work at Columbia University! We would like to send special thanks to Prof. Tai-ping Sun at Duke for taking care of Emily when she was away from the lab. Also, many thanks to her committee members - Philip Benfey, Dave McClay, and Tso-Pang Yao - for their valuable suggestions and advice to Emily in the past years.
Emily received a JBC/Herb Tabor Young Investigator Award at the 28th International Conference on Arabidopsis Research in St. Louis, MO (June 19-23, 2017). Emily gave a short talk on her Ph.D. work on identification of a novel light signaling component in controlling chloroplast biogenesis. The JBC/Herbert Tabor Young Investigator Awards are given annually to students, postdoctoral researchers, and pre-tenure faculty members who exemplify Tabor's values of creativity and scientific excellence.

M. Chen lab will host another summer CEPCEB REU student - Ngoc (Iris) Tran. This is the second year that we participate in the NSF-funded summer undergraduate research program in the Center for Plant Cell Biology at UCR. Iris will work with Dr. Keunhwa Kim, a senior scientist, to characterize the mechanism of subcellular protein sorting in plants. Welcome Iris!
Chris Cheng received a Research in Science & Engineering (RISE) fellowship for his summer research project. Congratulations!
Chris Cheng was awarded a Research in Science & Engineering (RISE) fellowship to conduct undergraduate research in the M.Chen lab between June 26 and September 1, 2017. Chris will be working with Chan Yul to investigate the mechanism of light signaling in controlling chloroplast biogenesis. Congratulations, Chris!
Dr. Xiao-teng Cai joined the M. Chen lab as a postdoctoral fellow. Xiao-teng obtained his Ph.D. from University of Science and Technology of China, where he worked with Prof. Chengbin Xiang on stress responses in Arabidopsis. Xiao-teng will investigate the mechanism of subnuclear reorganization by light signaling. Welcome Xiao-teng!
Andrew’s paper on the mechanism for dual-targeting HEMERA to plastids and the nucleus has been published in Plant Physiology.
Andrew Nevarez and Yongjian Qiu published their report in Plant Physiology on the mechanism of dual-targeting of HEMERA/pTAC12 to plastids and the nucleus. Their study suggests that the nuclear localization of HEMERA is mediated by a plastid-to-nucleus protein translocation mechanism - HEMERA is localized to plastids first before relocated to the nucleus. A similar mechanism was reported for WHIRLY1 in tobacco by Karin Krupinska and colleagues (Isemer R. et al. 2012 FEBS Lett 586(1):85-8). However, the mechanism of plastid-to-nuclear protein translocation is still largely unknown. Our study indicates that a plastid-to-nucleus retrograde protein translocation mechanism exists in Arabidopsis. Chan Yul Yoo is a co-author of the paper. We collaborated with Dr. Danny Schnell's lab at Michigan State for the studies on HEMERA's chloroplast import. We would also like to thank Dr. Philip Benfey for supervising Andrew's work in the past year. Congratulations to all authors! You can read the article here.
