Strains of Erwinia herbicola lost yellow pigmentation and thiamine prototrophy at high frequency when grown at elevated temperature (38 degrees C) or in the presence of sodium dodecyl sulfate. All pigmentless, thiamine-auxotrophic variants had lost a large plasmid (ca. 350 megadaltons). Conversely, all pigmented, thiamine-prototrophic strains contained the large plasmid. The evidence presented indicates that pigmentation and thiamine prototrophy are specified or controlled by genes carried on the 350-megadalton plasmid.
草本欧文氏菌菌株在高温（38摄氏度）下生长或在十二烷基硫酸钠存在的情况下，会高频丧失黄色色素沉着和硫胺素原养型。所有无色素、硫胺素营养缺陷型变体都丢失了一个大质粒（约350兆道尔顿）。相反，所有有色素、硫胺素原养型菌株都含有这个大质粒。所提供的证据表明，色素沉着和硫胺素原养型由350兆道尔顿质粒携带的基因所决定或控制。
