Paddy commonly faces drought and bacterial infection during growth process. This
may reduce the morphological and physiological quality. The aim of this study is to
investigate the pathological effect of Xanthomonas oryzae infection on local drought
tolerance paddy, MR219-4, under drought condition. The effect of Xanthomonas
oryzae to the plant morphological trait, fatty acid content and bacterial kinetic on
MR219-4 were observed in each growth phases. The result shows that there are no
significant differences in the morphological and physiological between the infected
and non-infected MR219-4. Interestingly, the presence of bacterial colonies was
observed in the infected paddy. These indicate that the infected MR219-4 exhibit
stochastic response to the Xanthomonas oryzae but they manages to overcome the
infection. In conclusion, the MR219-4 is resistant to the Xanthomonas oryzae infection
even under drought stress. This study would contribute to the improvement of local
rice varieties selection especially in the drought-prone area.
