PHLOEM UNLOADING

Tightening the pores to unload the phloem

Subjects

Root growth depends on the shoot-to-root transport of assimilates through the phloem, which is connected to the meristems by plasmodesmata pores. A PHLOEM UNLOADING MODULATOR is now identified to regulate plasmodesmata internal organisation, leading to pores that appear tighter but are more efficient for transport.
