Abstract

Grain discolouration can be attributed to both fungi and bacteria, where previous studies have largely ignored the involvement of bacterial pathogens in grain discolouration in northern Queensland (QLD). However, a few reports shown the involving bacteria in grain discolouration in southern New South Wales. The purpose of this study was to investigate the involvement of bacteria in rice grain discolouration in northern QLD. More than 40 bacterial isolates were obtained from discoloured grains collected from northern QLD during the wet and dry seasons in 2018 and the wet season in 2019. Identification based on 16S rRNA gene sequencing was performed for all the isolates, followed by a pathogenicity test on a single rice cultivar, Opus.
