New Report of Curvularia pseudobrachyspora Causing Brown Spot on Costa Rican Pitahaya Fruit (Hylocereus costaricensis) in Thailand
In J une 2021, brown spots was observed on Costa Rican pitahaya fruits (Hylocereus costaricensis) in a dragon fruit cultivation in Phatthalung province, southern Thailand. Infected dragon fruits showed small, circular, brown spots that expanded later to irregular shapes and the center of the symptomatic spot becoming dark brown with age. The fungus was isolated and cultured on potato dextrose agar (PDA) for morphological observation. Based on the macroscopic and microscopic features and phylogenetic tree of combined glyceraldehyde-3-phosphate dehydrogenase (gpd), internal transcribed spacer (ITS), and large subunit (LSU) sequences, this isolate was identified as Curvularia pseudobrachyspora. Pathogenicity tests by agar plug method revealed that this fungal isolate caused brown spot disease on Costa Rican pitahaya fruits with observations similar to the natural infection. To our knowledge, this is the first report of C. pseudobrachyspora causing brown spot disease on Costa Rican pitahaya fruits in Thailand.
期刊介绍：
The Chiang Mai Journal of Science is an international English language peer-reviewed journal which is published in open access electronic format 6 times a year in January, March, May, July, September and November by the Faculty of Science, Chiang Mai University. Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so.
