求教!miRNA相关!
The MIR396 family was present in the common ancestor of all tracheophytes (vascular plants),while the MIR397 and MIR398 families were acquired in the common ancestor of all spermatophytes .Ten families are present in all angiosperm lineages,while all other families display more restricted taxonomic distributions.怎么翻译和理解!特别是” restricted taxonomic distributions“

我的理解是,miR396、miR397、miR398这样的miRNA在维管植物/被子植物中广泛存在,然而其他的miRNA则大多只出现在某一类物种中.
因为有很多保守性强的miRNA,通过降解mRNA调节某些最基础的蛋白的翻译,这些miRNA在很多植物里都是有的,但有些特异性较强,就只在某类植物中出现,而非整个被子植物都会有此类miRNA
