Insertional mutants: a foundation for assessing gene function

Trends Plant Sci. 2003 May;8(5):205-7. doi: 10.1016/S1360-1385(03)00055-4.


The abundance of Arabidopsis insert mutants portends the day when null alleles in every gene will be obtained. Once these are created, all plant scientists can become geneticists. However, this brief technical highlight of genetic concepts cautions against ascribing gene function based exclusively on phenotypic analysis of null alleles.
