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

黄檀树病（Mundulla Yellows， MY）是最近发现的一种广泛存在于澳大利亚桉树属的致命病害，严重威胁着澳大利亚的生物多样性和生态保护。它具有传染性，显然是生物性的，但致病因子尚不清楚。查明原因对于制定可持续的控制措施至关重要。我们已经检测到一系列与myi相关的rna构成了疾病的“指纹”。为了识别与MY独特相关的单个rna，我们的目标是比较来自不同部位和不同症状的一系列受影响物种的MY- rna指纹。候选rna将被克隆用于建立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.
