Conjugation of ATG8 to vacuolar membranes as a response to cell wall damage
Plant Science Research WeeklyATG8 is a well-characterized protein involved in autophagy that binds to the double-membrane enclosed phagophore. In a new preprint, Julian et al. explore their finding that ATG8 binds to the single-membrane enclosed vacuolar membrane (tonoplast). They observed that this binding is enhanced by treatments…

Signaling secrets: FERONIA´s dynamic interplay with interactors at the cell surface
Plant Science Research WeeklyNamed after the Etruscan goddess of fertility, the receptor-like kinase FERONIA (FER) is involved in more than fertility. A recent paper by Liu, Yeh et al. sheds light on the intricate signaling processes taking place on the cell surface in response to environmental signals regulating growth and development…
Point mutations in the catalytic domain disrupt cellulose synthase vesicle trafficking and protein dynamics
Plant Science Research WeeklyCellulose is an important and useful biopolymer, present in plant cell walls and synthesized at the plasma membrane by protein complexes called cellulose synthase complexes (CSCs) composed of multimers of cellulose synthase (CESA). CESAs are embedded in the membrane and move along the membrane as they…
