Stromules are extended by plastids but the underlying basis for their extension and retraction had not been understood until recently. Our live-imaging aided observations on coincident plastid stromule branching and ER tubule dynamics open out new areas of investigation relating to these rapid subcellular interactions. The addendum provides a testable hypothesis on the formation of stromules, which argues against the need for new membrane incorporation and suggests that stromal extensions might result from a remodeling of the plastid envelope membrane in an ER aided manner.
Stromules 通过质体延伸，但直到最近，其延伸和回缩的基础原理还不为人知。我们通过实时成像辅助观察到的 coincident plastid stromule branching 和 ER tubule dynamics，为这些快速的亚细胞相互作用开辟了新的研究领域。附录提供了一个关于 stromules 形成的可测试假说，该假说反对需要新的膜整合，并表明 stromal 延伸可能是质体包膜膜在 ER 辅助下重塑的结果。
