- The intracellular distribution of the neurotoxin 2,4-diaminobutyric acid (DABA) in mature leaves of the perennial legume Lathyrus sylvestris L. var 'Lathco' (flatpea) was determined using subcellular fractions from mesophyll protoplasts. Chloroplasts contained about 15% of the cellular DABA. At least 75% of the DABA was vacuolar, based on the assumptions that each protoplast contained a single vacuole and that acid phosphatase occurred exclusively in the vacuole. DABA was not detectable in peroxisomal and mitochondrial fractions. Because the vacuole is not a major site of amino acid synthesis, this distribution implicates synthesis of DABA within chloroplasts with subsequent transport to and storage within the vacuoles of the mesophyll cells.
