Diversité des formes d'accumulation de la phytoferritine dans les cellules constituant l'épithème des hydathodes de Taraxacum officinale Weber et Saxifraga aizoon Jacq.

摘要: In Taraxacum officinale and Saxifraga aizoon particular aggregations found in plastids of epithem are considered to be phytoferritin. The diversity plant ferritin arrangement within the is studied. High magnification study these inclusions indicates that they can classified morphologically into three distinct groups: dense amorphous aggregate (F1), crystalline inclusion (F2) diffuse paracrystalline (F3). (F1) structures both present aizoon; similarly, (F3) officinale. Because their location nature organization, we think phytoferritin complexes under discussion may important synthesis or utilization living plant.
