No water-socking symptom was observed (Fig. 1A). Weisolated bacteria from small pieces (3−5 mm) of infected tissue ofstem or glume. Tissues were surface-sterilized for 30 s in 1%hypochlorite solution followed by rinsing in sterile distilled water.Tissues were macerated using a pipette tip in 100- µl of water in a 1.5ml Ependorf tube. The macerated tissue was left to soak for 10 min,after which 5 µl of liquid suspension were streaked onto Tryptic SoyBroth agar medium (TSA). Representative colonies were purifiedby repeated sub-cultures. Bacterial isolates were stored at −80 |
