Zusammenfassung

Die Piastiden des leitbündelnahen Parenchyms sehr junger BananenblÄtter enthalten neben StÄrke, Prolamellarkörpern und Thylakoiden in ihrem Stroma bis zu lΜ gro\e Eiwei\-kristalloide, die einen regelmÄ\igen Feinbau aus filamentartig angeordneten 50–60 å weiten Untereinheiten erkennen lassen. Die Kristalloide sind von einer Hülle umgeben, die hÄufig mit dichten Thylakoidstapeln in Verbindung steht.

Summary

In very young banana leaves plastids of the parenchyma cells near the vascular bundles contain about 1 Μ large crystalloids in their stroma, besides starch, prolamellar bodies and thylacoids. The crystalloids have a very regular fine structure consisting of 50–60 å filament-like subunits and are surrounded by a membranous envelope that often is in contact with stacks of thylacoids. Form and array of the crystalloid subunits are finally compared with protein-crystalloids inPhaseolus plastids, intramitochondrial crystals and crystal-containing bodies.
