Hot and SUMOylated: Heat-induced SUMOylation controls effectors in plant cells

/in /by

Li et al. examine heat-induced SUMOylation of bacteria effectors in Arabidopsis. (Plant Cell. 2024) By Wenliang Li and Jianbin Lai (South China Normal University) https://doi.org/10.1093/plcell/koae049 Background: Bacterial pathogens deliver effectors into plant cells to interfere with host immunity and these effectors are targeted by host cells. Environmental factors affect this interaction between bacteria and plants. […]
