Figure 1. Phosphate (Pi) starvation confers rice resistance toXanthomonas oryzae pv. oryzae (Xoo) infection.
(a) Growth of Xoo strain PXO91 in wild-type Nipponbare (NIP) leaves upon Pi starvation treatment. Plants were grown with or without Pi solution for three days and then inoculated with Xoo . Leaves clipped by dipping scissor tips in sterilized water were used as control. The bacterial population was measured from three leaves at each time point in terms of colony-forming units (cfu). Leaf fragments (6 cm) were sterilized using 75% ethanol, ground separately, suspended in sterilized water, and plated on peptone sucrose agar in a 10-fold dilution series. Different letters indicate significant difference at P < 0.05 by Fisher’s least significant difference tests. (b) Bacterial blight symptoms in wild-type NIP leaves at 14 days after inoculation withXoo . (c) Lesion length on the fifth leaf blades at 14 days after inoculation with Xoo . Values are means ± SE (n = 15). * P< 0.05, Student’s t -test.
