- ‘Inside the phloem, it seems to be a common feature that companion cells are the principal receivers of the translocated photosynthates from the shoot through sieve tubes.’
- ‘In the beans, the needle-shaped protein complexes are situated in so-called sieve tubes, where they control the plant's flow of sugar-bearing fluid.’
