Abstract

Micropropagated plants infected with ' Phytoplasma asteris' showed virescence symptoms, witches' broom symptoms, or became asymptomatic after their planting in pots. Nine plants were grouped into three categories according to these symptoms, which were then employed for investigation. The phytoplasma concentration, as determined by qPCR, correlated well with the severity of symptoms. To reveal the changes in the small RNA profiles in these plants, small RNA high-throughput sequencing (HTS) was carried out. The bioinformatics comparison of the micro (mi) RNA and small interfering (si) RNA profiles of the symptomatic and asymptomatic plants showed changes, which could be correlated to some of the observed symptoms. These results complement previous studies on phytoplasmas and serve as a starting point for small RNA-omic studies in phytoplasma research.

摘要

经过微繁殖的感染“植原体 asteris”的植物在盆栽种植后表现出变绿症状、扫帚症状或无症状。根据这些症状，将 9 株植物分为三组进行调查。通过 qPCR 确定的植原体浓度与症状的严重程度密切相关。为了揭示这些植物中小 RNA 谱的变化，进行了小 RNA 高通量测序 (HTS)。对有症状和无症状植物的 micro (mi) RNA 和 small interfering (si) RNA 谱的生物信息学比较显示出变化，这些变化与一些观察到的症状有关。这些结果补充了以前关于植原体的研究，并为植原体研究中的小 RNA 组学研究提供了起点。
