Abstract

Abstract Rice sheath rot caused by some pathogens. It occurs in the upper leaf sheath that wraps the rice panicle, its major features are rotting, discoloration, sometimes affecting rice grain production. Lampung is an important rice-producing area in Indonesia. Currently, rice sheath rot in the area is reportedly caused by Fusarium sulawesiense and Fusarium hainanense. This study aimed to identify the rice sheath rot pathogen accurately by sampling locations at varying altitudes, plant ages, and varieties in Lampung Sampling was conducted in Lampung, infected plants were collected and the pathogen isolates were molecularly characterized on the basis of DNA sequence data for the internal transcribed spacer and translation elongation factor 1-α. Pathogenicity test results showed that 16 fungal isolates caused rice sheath rot. These isolates were identified as Sarocladium oryzae, Fusarium bubalinum, F. hainanense, Setophoma poaceicola, Curvularia geniculata, and Alternaria padwickii. This study is the first to report that S. poaceicola is a pathogen of rice sheath rot.

与印尼楠榜稻鞘腐病有关的真菌

摘要水稻鞘腐病是由一些病原菌引起的。它发生在包裹稻穗的上部叶鞘，其主要特征是腐烂、变色，有时影响稻谷产量。楠榜是印尼重要的水稻产区。目前，据报道，该地区水稻鞘腐病是由苏拉维镰刀菌和海南镰刀菌引起的。本研究旨在通过不同海拔高度、不同植株年龄和不同品种的取样地点，准确鉴定南坪稻鞘腐病病原菌。在南坪稻鞘腐病取样，采集受感染植株，根据内部转录间隔段和翻译伸长因子1-α的DNA序列数据，对病原菌分离物进行分子鉴定。致病性试验结果表明，16株真菌可引起水稻鞘腐病，分别为稻瘟弧菌(Sarocladium oryzae)、白腐镰刀菌(Fusarium bubalinum)、海南镰刀菌(F. hainanense)、poaceicola Setophoma geniculata和padwickii Alternaria。本研究首次报道了稻鞘腐病的病原菌poaceicola。
