A comparative study of the distribution and spread of potential molecular markers for Mundulla Yellows disease

蒙杜拉黄化病(My)是近年来在澳大利亚发现的一种广泛流行的桉树致死性病害，对国家生物多样性和保护工作构成严重威胁。它具有传染性，表面上是生物性的，但病因尚不清楚。查明原因对于制定可持续的控制措施至关重要。我们检测到了一系列与My相关的RNA，它们构成了一种疾病的“指纹”。为了识别与My唯一相关的单个RNA，我们的目标是比较来自不同地点和不同症状的一系列受影响物种的My-RNA指纹。将克隆候选RNA，用于建立My的分子诊断和确定病因。

Mundulla Yellows (MY), a newly recognised widespread lethal disease of Eucalyptus spp.in Australia, is a serious threat to national biodiversity and conservation. It is contagious, apparently biotic, but the causal agent is unknown. Identification of the cause is essential to establish sustainable control measures. We have detected a range of MY-associated RNAs constituting a disease 'fingerprint'. To identify individual RNAs uniquely associated with MY we aim to compare MY-RNA fingerprints from a range of affected species from different sites and with varying symptoms. Candidate RNAs will be cloned both for establishing molecular diagnostics for MY and identifying the cause.
