有一个问题，Dna.CO1.raw是一个变量，是个list，当我输入Dna.CO1.raw[1]的时候，得到下面的data
>Dna.CO1.raw[1]$`gi|507180915|gb|KC132826.1| Trichophya pilicornis voucher ZMUN:10008478 cytochrome oxidase subunit 1 (CO1) gene, partial cds; tRNA-Leu (Leu2) gene, complete sequence; and cytochrome oxidase subunit 2 (CO2) gene, partial cds; mitochondrial`

现在我想要直接得到$`gi|507180915|gb|KC132826.1| Trichophya pilicornis voucher ZMUN:10008478 cytochrome oxidase subunit 1 (CO1) gene, partial cds; tRNA-Leu (Leu2) gene, complete sequence; and cytochrome oxidase subunit 2 (CO2) gene, partial cds; mitochondrial`
这串字符串，不知道应该怎么做？？？？？
求教大神！！
谢谢
