Abstract

Cinnamomum burmanni, also referred to as Indonesian cinnamon or Padang cassia, is an edible, medicinal and landscape plant. In recent years, it has been affected by a foliar disease in Nanchang, China, and its growth and value have been compromised. Koch's postulates were fulfilled by inoculating spore suspensions through artificial wounding for pathogenicity tests and followed by reisolating of the pathogen from infected leaves. Colletotrichum siamense was identified as the causal agent of C. burmanni anthracnose based on morphological characteristics and multi-locus phylogenetic analyses. Phylogenetic trees were constructed using maximum likelihood and Bayesian inference based on the following loci: the internal transcribed spacer, chitin synthase, actin, glyceraldehyde-3-phosphate dehydrogenase and calreticulin. As far as we know, this finding is the first time to report that C. siamense is responsible for causing C. burmanni anthracnose. This study provides critical insights for managing the disease at the appropriate stage.

肉桂炭疽菌引起的炭疽病首次报道

肉桂，也被称为印度尼西亚肉桂或巴东决明子，是一种可食用、药用和景观植物。近年来，南昌市发生了一种叶面病害，影响了其生长和价值。科赫的假设是通过人工损伤接种孢子悬浮液进行致病性测试，然后从被感染的叶子中重新分离病原体来实现的。通过形态学特征和多位点系统发育分析，确定了炭疽杆菌为缅甸炭疽病的病原。利用最大似然和贝叶斯推理方法，以内部转录间隔酶、几丁质合成酶、肌动蛋白、甘油醛-3-磷酸脱氢酶和钙网蛋白为基础，构建了系统发育树。据我们所知，这一发现是首次报道C. siamense是导致C. burmanni炭疽病的原因。这项研究为在适当的阶段控制疾病提供了重要的见解。

期刊介绍： The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics: -Abiotic damage- Agronomic control methods- Assessment of pest and disease damage- Molecular methods for the detection and assessment of pests and diseases- Biological control- Biorational pesticides- Control of animal pests of world crops- Control of diseases of crop plants caused by microorganisms- Control of weeds and integrated management- Economic considerations- Effects of plant growth regulators- Environmental benefits of reduced pesticide use- Environmental effects of pesticides- Epidemiology of pests and diseases in relation to control- GM Crops, and genetic engineering applications- Importance and control of postharvest crop losses- Integrated control- Interrelationships and compatibility among different control strategies- Invasive species as they relate to implications for crop protection- Pesticide application methods- Pest management- Phytobiomes for pest and disease control- Resistance management- Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
