AB - Sieve elements (SEs) degrade selected organelles and cytoplasmic structures when
they differentiate. According to classical investigations, only smooth ER,
mitochondria, sieve element plastids, and, in most cases, P-proteins remain in
mature SEs. More recent proteomics and immuno-histochemical studies, however,
suggested that additional components including a protein-synthesizing machinery
and a fully developed actin cytoskeleton operate in mature SEs. These
interpretations are at odds with conventional imaging studies. Here we discuss
potential causes for these discrepancies, concluding that differentiating SEs may
play a role by 'contaminating' phloem exudates.
