Zinc plays many essential roles in life. As a strong acid that lacks redox activity under environmental and cellular conditions, the Zn 2+ cation is central in determining protein structure and catalytic function of nearly 10% of most eukaryotic proteomes. While specific functions of zinc have been elucidated at a molecular level in a number of plant proteins, wider …

This year, research progress on phase separation in plants seems to have slowed, with only a few research articles published in the first half of 2023 (Wang et al., 2023a, 2023b) (Figure 1). The discovery of phase separation was initially exciting, but biologists have become divided as more and more studies have been published.
