Abstract
Conductivity of intercellular fluid sharply increased in 24 to 48hr after susceptible Natsudaidai leaves were inoculated with Xanthomonas citri. At the same time, amino acids were released into intercellular spaces increasing in concentration several times in 48hr compared with uninoculated leaves. The major amino acids in intercellular fluid from inoculated leaves were: proline, anserine, γ-amino-n-butyric acid, serine, alanine and aspartic acid. Carnosine and ethanolamine were detected as new amino acids in the infected tissues. Electrolyte leakage also occurred in leaves of Calamondin, a resistant cultivar, although the growth of X. citri was kept low during the period of observation. Strain V2 of Erwinia herbicola induced rapid leakage of electrolytes and extremely rapid movement of amino acids into intercellular spaces in Natsudaidai leaves. Strain F1 of the same bacterium, however, did not induce these reactions. The bacterial populations quickly declined when incompatible xanthomonads were inoculated into Natsudaidai leaves. There was considerable alteration in amino acid compositions of host cells inoculated with X. phaseoli but not in those of intercellular fluid, indicating that the host cell membrane did not suffer serious damage. The changes found in the leaf tissues inoculated with X. citri seemed to be situated between these two.
