BglaTNB6, a tailocin produced by a plant-associated nonpathogenic bacterium, prevents rice seed-borne bacterial diseases.

ABSTRACT: Rice seed-borne diseases caused by the bacterial pathogens Burkholderia glumae and B. plantarii pose a major threat to rice production worldwide. To manage these diseases in a sustainable manner, a biocontrol strategy is crucial. In this study, we showed that B. gladioli NB6 (NB6), a nonpathogenic bacterium, strongly protects rice from infection caused by the above-mentioned pathogens. NB6 was isolated from the indica rice cultivar Nona Bokra seedlings, which possesses genetic resistance to B. glumae. We discovered that cell suspensions of NB6 and its culture filtrate suppressed the disease symptoms caused by B. glumae and B. plantarii in rice seedlings, which indicated that NB6 secretes a plant-protective substance extracellularly. Through purification and mass spectrometry analysis of th
