The phloem provides a network of sieve tubes for long-distance translocation of photosynthates. For over a century, structural proteins in sieve tubes have presented a conundrum since they presumably ...

This is a preview. Log in through your library . Abstract Background and Aims Phloem evolution has been explored in the literature across very broad scales, either for vascular plants as a whole or ...

Researchers have combined traditional genetic approaches with 3-D reconstructions from scanning electron microscopy to discover and characterize genes regulating the development of plant sieve ...

RECENTLY reports have been published of microscopic particles moving along strands in the sieve tubes of cut sections of Primula obconica 1,2. This movement has suggested that protoplasmic streaming ...

Transport in biology means carrying substance absorbed or made in the body of an organism to all other parts of its body. In plants, it is only water and minerals that need to be transported to its ...
