    • Infection by human rhinovirus (HRV) causes upper and lower respiratory tract disease with varying degrees of virulence. The molecular basis of diversity was examined by completing the genome sequences for all known serotypes (n=99) as well as novel field samples. Superimposition of capsid crystal structure and optimal-energy RNA configurations established the alignments. The phylogeny revealed conserved motifs, Glade-specific diversity including a potential new species (clade-D), pan-genome mutations in field isolates, and unexpected recombination that contributes to heterogeneity. A spacer tract near a 5′-UTR cloverleaf was hypervariable, and in analogy with poliovirus, may be associated with virulence. A previously unidentified configuration consistent with non-scanning internal ribosome entry may account for rapid protein translation. The data density from complete sequences of the HRV reference serotypes provided high resolution for this degree of modeling, and serves as a platform for full genome-based epidemiologic studies, for viral diagnostics and prognostics, and for antiviral compounds and vaccines.
    • 人类鼻病毒(HRV)的感染导致上呼吸道和下呼吸道疾病具有不同程度的毒力。 通过完成所有已知血清型(n = 99)的基因组序列以及新的野外样本来检查多样性的分子基础。 衣壳晶体结构和最佳能量RNA配置的叠加建立了比对。 系统发育显示保守的基序,Glade特异性多样性,包括潜在的新物种(进化枝D),野外分离物中的泛基因组突变以及有助于异质性的意外重组。 5'-UTR三叶草附近的间隔区是高变的,类似于脊髓灰质炎病毒可能与毒力相关。 与非扫描内部核糖体进入一致的先前未鉴定的构型可以解释快速的蛋白质翻译。 来自HRV参考血清型的完整序列的数据密度为该程度的建模提供了高分辨率,并且作为用于病毒诊断和预后以及用于抗病毒化合物和疫苗的全基因组流行病学研究的平台。
