Propagule pressure (i.e., the number of propagules) has long been recognized to play an essential role in plant invasion. But it is not clear whether propagule pressure influences the invasion of exotic plants into native plant communities when different frequencies of nitrogen are added. We established an experiment with three plant communities that included native plant communities alone (four grasses, two legumes and two forbs) or native plant communities with one or five invasive plants,...

KAT7-mediated CANX (calnexin) crotonylation regulates leucine-stimulated MTORC1 activity

Guokai Yan, Xiuzhi Li, Zilong Zheng, Weihua Gao, Changqing Chen, Xinkai Wang, Zhongyi Cheng, Jie Yu, Geng Zou, Muhammad Zahid Farooq, Xiaoyan Zhu, Weiyun Zhu, Qing Zhong & Xianghua Yan
Amino acids play crucial roles in the MTOR (mechanistic target of rapamycin kinase) complex 1 (MTORC1) pathway. However, the underlying mechanisms are not fully understood. Here, we establish a cell-free system to mimic the activation of MTORC1, by which we identify CANX (calnexin) as an essential regulator for leucine-stimulated MTORC1 pathway. CANX translocates to lysosomes after leucine deprivation, and its loss of function renders either the MTORC1 activity or the lysosomal translocation of MTOR insensitive...
