Intracellular Distribution of Organic and Inorganic Anions in Mesophyll Cells: Transport Mechanisms in the Tonoplast
Plants contain organic as well as inorganic ions. Both play an important role in metabolism. Malic acid accumulates in the vacuoles of CAM plants during the night, and this process is reversed during the daytime (Osmond and Holtum, 1981). In contrast, in leaves of C3 plants, vacuolar levels of malate are high at the end of the day and low in the morning (Gerhardt and Heldt, 1984). Both examples reflect the dynamics of vacuolar compartmentation.
