The CHARA Array is a six 1 m telescope optical/IR interferometric array located on Mount Wilson, California, designed and built by the Center for High Angular Resolution Astronomy of Georgia State University. In this paper we describe the main elements of the Array hardware and software control systems, as well as the data reduction methods currently being used. Our plans for upgrades in the ne...

When the nodal end of an internodal cell of Chara corallina was subjected to a pulse treatment with artificial cell sap, a depolarization lasted in artificial pond water. This depolarization could also be induced by pulse treatment with KCl solution, indicating that K+ in the artificial cell sap is responsible (K+ -induced depolarization). The depolarization was prolonged in the presence of 2 m...

One of the central problems in the cell is how to transport molecules around the cell to desired locations. Since low Reynolds number conditions apply and diffusional times are large, without the aid of molecular motors to transport the fluid quickly cells could not survive, yet diffusion is still essential for the ultimate delivery of the goods. This paradox of low Reynolds numberlarge Peclet ...

The RAB5 GTPase ARA6 of Arabidopsis thaliana is known to be involved in endosomal trafficking by targeting vesicles to the plasma membrane. During this process AtARA6 is working in close relationship with the SNARE protein VAMP727 (vesicle associated membrane protein 727). Recently, ARA6 of the characean green algae Chara australis (CaARA6) was shown to have properties similar to AtARA6, pointi...
