Abstract: | Plastidic bridges in the plant cell network: Stromules Stromules are mobile protrusions emanating from plastids. They might form bridges between plastids and connect them also with other compartments of the plant cell. They could be involved in coordination of plastid activities and in signalling. Stromules have been first observed in the water fern Selaginella more than 100 years ago. Later improved light microscopy enabled the visualization of stromules in higher plant plastids. 15 years ago, since plants accumulating the green fluorescing proteins (GPF) in the stroma became available they have been newly detected and are now studied intensively. Formation of stromules differs among plant tissues, developmental stages and environmental situations. Actin and myosin are required for the formation of stromules. |
