求翻译：另外，GenBank数据库的完善是分子鉴定的基础。由于GenBank数据库中炭角菌属rDNA-ITS 序列数据不够丰富，因而使从分子水平进行炭角菌种的鉴定受到了一定限制，需要进一步完善是什么意思？

In addition, GenBank database is the perfect basis for molecular identification. GenBank database as Xylaria sp rDNA-ITS sequence data is lacking, thus making the molecular level the identification of Xylaria species has been limited, the need to further improve

Moreover, the GenBank database consummation is the molecular appraisal foundation.Because in the GenBank database the coal angle bacteria rDNA-ITS sequence data insufficiently is rich, thus caused from the molecular level to carry on the coal angle mold mushroom spawn the appraisal to receive certai

In addition, the perfection of the GenBank database is the basis for identification. Due to the species of the genus rDNA-ITS, carbon point sequences in GenBank database data is not rich enough, making carbon from the molecular level of angle strain identification subject to certain restrictions, yo
