Phytomonas: Transport of amino acids, hexoses and polyamines
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 min-1 10-7 cells, respectively) and lower, but significant rates, for proline, a...
