Draft genome sequences of Rahnella perminowiae, R. aceris, and R. aquatilis isolated from onion bulbs (Allium cepa L.) displaying symptoms of bacterial rot

Abstract

Onions (Allium cepa L.) are among the most widely produced vegetables globally, and their cultivation plays an important role in food security (Schwartz et al. 2007). However, the emergence of opportunistic bacterial plant pathogens, such as Rahnella species, which are not fully understood yet, poses a threat to onion production (Asselin et al. 2019; Brady et al. 2022). Rahnella species are Gram-negative, facultative anaerobes within the Yersiniaceae family, part of the order Enterobacteriales (Adeolu et al. 2016). According to the List of Prokaryotic Names with Standing in Nomenclature (LPSN), the genus consists of 15 described species that are isolated from various environments and are considered validly characterised (Guo et al. 2012; Brady et al. 2014; Lee et al. 2019; Liang et al. 2020).
