Abstract Burkholderia anthina XXVI is a rhizosphere bacterium isolated from a mango orchard in Mexico. This strain has a significant biological control activity against the causal agent of mango anthracnose, Colletotrichum gloeosporioides, likely through the production of siderophores and other secondary metabolites. Here, we present a draft genome sequence of B. anthina XXVI (approximately 7.7 Mb; and G + C content of 67.0%), with the aim of gaining insight into the genomic basis of antifungal modes of action, ecological success as a biological control agent, and full biosynthetic potential. Keywords Burkholderia · Biocontrol agent · Colletotrichum · Genome Sequencing · Siderophore
Introduction Anthracnose spots and blights, caused by fungal pathogens of the genus Colletotrichum, are among the top ten most devastating crop diseases of the world (Dean et al. 2012). Severity of anthracnose is greatest when climatic conditions are

conducive to its development, and is particularly devastating post-harvest. Historically, this disease has been controlled by application of chemical fungicides, frequently leading to pathogen resistance, and residual contamination in fruits (de los Santos-Villalobos et al. 2011; Chung et al. 2010). While combinations of chemical fungicides may reduce the emergence of pathogen resistance, microbial biological control agents are attractive alternatives and potential supplements to chemical fungicides for robust control of anthracnose and other crop diseases. Use of plant- and soil-derived microorganisms with intrinsic mechanisms to antagonize pathogens has shown great promise for controlling diseases of agricultural importance, under both organic and non-organic management regimes (Berg 2009; Parnell et al. 2016).
