Burm. f.] showed several changes in cell ultrastructure when compared with control calli. Both types of calli comprised clusters of meristematic cells, but salt-tolerant calli had several structural differences: thick cell walls, ring-shaped mitochondria, an inccreased content of lipid bodies, microbodies and parallel accumulation of rough endoplasmatic reticulum. These structural features seem to be related with salt tolerance in Citrus limon cells.  aCitrus limon  atissue culture  aultrastructure  aCultura de Tecido  aCalos embriogenicos  aCitros limon  aEmbriogenic callus  aNaCl-tolerance  aTolerancia ao cloreto de sodio  aUltra estrutura1 aOLMOS, E.1 aHELLIN, E.  tPlant Cell, Tissue and Organ Culturegv.39, n.1, p.13-18, 1994.
