Update: Callose synthesis in plant development – an evolutionary insight
Plant Science Research WeeklyCallose 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…
