Erwinia carotovora subsp. carotovora引起之番茄細菌性莖腐病

Bacterial stem rot of tomato caused by Erwinia carotovora subsp. Carotovora

"蕃茄（Lycopersicon esculentum Mill.）是台灣重要蔬果之一，栽培遍及全臺，面積達4,459公頃，各主要栽培地以其面積多寡依序為嘉義、台南、雲林、高雄、南投、彰化、屏東、花蓮、新竹、台東及宜蘭縣等。"

"Bacterial stem rot was found to cause severe losses of tomato in the Tsushan area, Nantou County, central Taiwan during 2001. The disease mainly affected stems of plants, which showed symptoms of being water-soaked and then turned dark brown. The slimy tissues resulted in hollow stems, and eventually the entire plant wilted. Masses of bacterial cells released from diseased tissues were observed under light microscopy. Strains of bacterium have consistently been isolated from diseased tissues. Based on physiological, biochemical, and pathogenicity tests, the Biolog identification system, and the polymerase chain reaction, the causal agent of this disease was identified as Erwinia carotovora subsp. carotovora."
