Webb4 nov. 2024 · Formation of the phloem filament matrix requires both SEOR1 and SEOR2 proteins. Live imaging of phloem flow and flow velocity measurements in individual sieve tubes indicate that SEOR1 agglomerations do not markedly affect or alter flow. Webb27 mars 2012 · The transport of assimilates, on the other hand, occurs in the phloem, a tissue that contains living cells called sieve elements. Consecutive, interconnected files of sieve elements form sieve tubes that are functionally supported by companion cells and phloem parenchyma.
