$P$-proteins

Vedclass · Answer

(C) $P$-proteins (Phloem proteins) are components found in large amounts in phloem sieve tubes. The main function of these bodies is to seal off the sieve tube element or sieve cell by bringing about the blockage of the sieve plate. These bodies perform this function when the sieve element is injured. These bodies and callose together block the pores of sieve tube elements. $P$-protein bodies and callose form blocking plugs. These bodies remain along the walls of sieve tube elements. $P$-protein bodies are assigned some role in the translocation of food material in the sieve tubes,but this is not universally accepted.
