Abstract
Phytomonas cells (Phytomonas Jma) isolated from the latex of Jatropha macrantha were assayed for amino acid, hexose and polyamine transport. Results showed high transport rates for glucose and fructose (193 and 128 pmol minâ1 10â7 cells, respectively) and lower, but significant rates, for proline, arginine, cysteine and glutamate (between 1.7 and 5.8 pmol minâ1 10â7 cells). Minor transport activities were observed for serine, glycine and aspartate (<1 pmol minâ1 10â7 cells). Amino acid transport processes do not seem to be regulated by starvation or during the growth phases. Polyamine transport was also evaluated showing a clear preference for spermidine over putrescine (3.4 and 0.4 pmol minâ1 10â7 cells, respectively). This work represents the first report on metabolite transport in phytomonads.
