520	3		_aBiotechnological advances in coffee research (in vitro manipulation, multiplication, generation and development of transgenic coffee plants with specific traits like high yield and good quality)have contributed to description of the metabolic pathways involved in the response mechanisms to environmental factors like abiotic stress. Coffea arabica L. plants grow in acidic soils, and therefore aluminium (Al)toxicity is a major negative impact on crop productivity. To understand Al toxicity mechanisms in cells via the Al absorption kinetic, we isolated protoplasts from two C. arabica L. suspension cell lines: Al-sensitive (L2)and Al-tolerant (LAMt). Protoplasts of LAMt line exhibited lower Al absorption levels than protoplasts of the L2 line. Use of two fluorescent tracers (morin and calcofluor white)indicated that Al interacts with internal cell structures, such as the plasma membrane and nucleus, with differences in both cell lines. Al-tolerance in the LAMt is probably associated with the cell wall as well as intracellular structures. These data will help to better understand Al toxicity in C. arabica, and Al toxicity mechanisms in plant cells.
