Young, Anthony J. and Marney, Thomas S. and Herrington, Mark and Hutton, Don and Gomez, Apollo O. and Villiers, Adam and Campbell, Paul R. and Geering, Andrew D. W. (2011) Outbreak of angular leaf spot, caused by Xanthomonas fragariae, in a Queensland strawberry germplasm collection. Australasian Plant Pathology, 40 (3). pp. 286-292. ISSN 0815-3191


Strawberry (Fragaria (×) ananassa) plants exhibiting leaf lesions consistent with angular leaf spot (ALS, caused by Xanthomonas fragariae Kennedy and King 1962) were identified in the Queensland strawberry germplasm at Bundeberg in May 2010. Water suspensions of bacterial ooze tested positive using a previously described primer set. However, the slow growth rate of X. fragariae and the presence of a fast-growing, nonpathogenic, undescribed Xanthomonas species presented problems that were overcome by dilution plating and DNA sequence analysis. Sequencing of the gyrB locus of putative colonies of X. fragariae indicated 100% sequence similarity to other X. fragariae isolates. A new set of diagnostic primers for X. fragariae based on the gyrB locus is presented.
