Meanwhile, although it is limited by gene redundancy, lethal knock outs, non-tagged mutants, T-DNA Insertional mutagenesis is also a useful tool for dissecting functions of different genes.

• T-DNA插入也是研究基因功能非常有用的工具之一，一些T-DNA插入突变的数据库已经被成功建立，其中的SALK库（SALK Institute Genomic Analysis Laboratory ，SIGnAL）包含了拟南芥基因组约74%25基因的T-DNA插入突变系。
