Ruiz-Solaní et al. examine how a cysteine protease interacts with stress granules, a type of membrane-less condensate, under heat stress and aging By Nerea Ruiz-Solaní1,2, Laia Armengot1,2 and Núria S. Coll1,3 1 Centre for Research in Agricultural Genomics (CRAG), CSIC-IRTA-UAB-UB, Bellaterra…

Update: Callose synthesis in plant development – an evolutionary insight

Callose is a polysaccharide with amorphous, gel-like properties that often serves as a transient matrix in plant cell walls. Callose deposition at plasmodesmata can regulate the movement of molecules between cells, transient callose deposition in phloem sieve elements occurs in response to stress, callose…
