This work has been developed by the FLUOR team (Kervella et al., 2003) (Observatoire de Meudon) in the K-band with a different experiment on the IOTA interferometer. This experiment is now implemented on CHARA. Figure 16 gives a schematic representation and a photo of this combiner. 

Nearly all the derivatives of 2,5-DMA exhibited radioligand binding charae-teristies at 5-HT2 serotonin reeeptors that were consistent with those of serotonin and other tryptamine agonists. It has been demonstrated... 

Fig. 6.23 Single-channel currents flowing across the membrane between the protoplast and vacuole of Chara corallina. Among several channels with different conductivity the recordings of the 130 pS channel are recorded here. The zero line is at the top of each curve. (By courtesy of F. Homble)...

Although Li+ appears to have no nutritional function, plants have the ability to absorb the cation, the uptake being inhibited by Ca2+ [248], The transport of Li+ in plant cells has received little attention its movement can be passive or mediated by Na+ channels [249] and in some reports Li+ actually blocks ion channels for instance it inhibits voltage-dependent K+ channels in Chara cells [250]. Li+ is unevenly distributed throughout the plant, being most concentrated in the cell walls [251].

It may be useful to introduce impermeant fluorocromes without micro-injection. Permeabilization is suitable for small to medium cells. Large cells (e.g., Chara ) can be permeabilized osmotically (46) and become permeable to the fluorescent analogue of ATP, e-ATP (46). Vacuolar compartmentation still occurs, but the cell wall is porous to molecules of only 4158 Dalton (approx 4.8 nm). Internal fluorescence concentration increases only slowly because of the large volume of cytoplasm.

The ER, Golgi bodies, and nuclear envelopes in cotyledon cells and cells of Chara corallina showed a marked increase in density by ZIO staining (38,39). We investigated the continuity of the Golgi apparatus into the ER of cultured tobacco protoplasts by ZIO staining (40).
