摘要

利用Nad5线粒体DNA序列对尼日利亚大蕉(Musa spp.， AAB)广泛发生的根瘤病进行了分析，病原鉴定为沙芽曲霉(Meloidogyne arenaria)。在对培养的群体进行接种后，科赫的假设得以实现，并观察到相同的症状。这首次从分子上证实了沙棘单胞菌对大蕉造成这种损害，并强调了它对作物的潜在威胁。众所周知，根结线虫会影响香蕉和大蕉的生产，但最近分子技术的改进才刚刚准确地确定了所涉及的物种的诊断。

A report of Meloidogyne arenaria Parasitizing Plantain (Musa spp., AAB) in Nigeria

Extensive root galling observed on plantain (Musa spp., AAB) in Nigeria was analysed using Nad5 mitochondrial DNA sequences and the causal agent identified as Meloidogyne arenaria. Following the inoculation of population cultured, Koch’s postulates was fulfilled and the same symptoms observed. This provides the first molecular confirmation of M. arenaria causing such damage to plantain and highlighting its potential as a threat to the crop. Root knot nematodes are known to affect banana and plantain production but diagnosis of the species involved is only just being accurately determined with the recent improvements in molecular techniques.

期刊介绍： Australasian Plant Disease Notes is an international journal for publication of short reports from all countries which describe original research that transcends national boundaries. All aspects of plant pathology are covered including new geographical records of diseases or pathogens, new pathogens or pathogen strains, taxonomic papers, quarantine notes, disease management and diagnostic methods. Australasian Plant Disease Notes is a publication of the Australasian Plant Pathology Society.
