Welcome Dr. Xiao-Teng Cai!

March 17th, 2017|Comments Off on Welcome Dr. Xiao-Teng Cai!

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.

February 28th, 2017|Comments Off on 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.

Andrew gave a beautiful dissertation talk on his Ph.D. project entitled “Mechanism of dual-targeting of HEMERA to the chloroplasts and nucleus”. He has also passed his Ph.D. defense. Congratulations Andrew on reaching this milestone in your life!

M. Chen lab received funds from NIH for purchasing a new confocal microscope for the UCR Imaging Core.

September 2nd, 2016|Comments Off on M. Chen lab received funds from NIH for purchasing a new confocal microscope for the UCR Imaging Core.

M. Chen lab received $155,000 supplemental funds from NIGMS to contribute to the purchase of a state-of-the-art Zeiss LSM880-Airyscan confocal microscope for the UCR Imaging Core.  We deeply appreciate the support from NIGMS. This is a joint grant application with two other NIGMS-supported PIs, Xuemei Chen and Zhenbiao Yang. Many thanks to the support from Vice Chancellor Michael Pazzani. This new confocal will greatly enhance our research as well as the research of many other cell biology labs at UCR.
