Abstract

Fig rust is one of the serious fungal diseases caused by Cerotelium fi ci which causes great loss to the overall growth and yield of the plant. This disease is generally characterized by pale reddish-brown to reddish-brown angular leaf spots, typically found on the adaxial surfaces of the leaves, whereas the corresponding abaxial surface of the same leaves was covered with a lot of orange rust pustules. With the progression of this rust disease, angular spots fused to form necrotic patches whereas, leaf edges curled upward. Premature abscission of leaves takes place, leaving bare branches and unripe fruits. This disease showed its global distribution in tropical and subtropical areas, however, the highest distribution was found in the African continent (18 countries) followed by Asia (14 countries), North & South America (10 countries each), Europe (8 countries) and 7 countries in the Oceanian continent. Apart from the rust pathogen Cerotelium fi ci, the Phakospora nishidana was also reported to cause fi g rust which has created confusion on the identity of C. fi ci as a fi g rust pathogen. This suggests a need to re-examine all specimens of fi g rust at the global scale, based on morphological and modern DNAbased methods so that the taxonomic ambiguities on fi g rust pathogens can be resolved and suitable control methods can be implemented to avoid serious crop and yield loss.

由陶瓷纤维引起的无花果锈病:过去、现在和未来
无花果锈病是由无花果病引起的严重真菌病害之一,对植物的整体生长和产量造成巨大损失。该病的一般特征为浅红褐色至红棕色的角状叶斑,通常出现在叶片的正面,而相同叶片的相应背面则覆盖着大量橙色锈疱。随着锈病的发展,角斑融合形成坏死斑,而叶边缘向上卷曲。叶子过早脱落,留下光秃秃的树枝和未成熟的果实。该病在热带和亚热带地区呈全球分布,但以非洲大陆分布最多(18个国家),其次是亚洲(14个国家)、南北美洲(各10个国家)、欧洲(8个国家)和大洋洲(7个国家)。除了铁锈病菌Cerotelium fici外,也有报道称西田Phakospora nishidana也会引起铁锈,这使人们对铁锈病菌的身份产生了混淆。这表明有必要在形态学和现代dna技术的基础上,在全球范围内重新检查所有的无花果锈病标本,以便解决无花果锈病病原体的分类歧义,并采取适当的控制方法,以避免严重的作物和产量损失。

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.
