| Research Abstract |
BOR6 is an efflux type boron transporter of Arabidopsis thaliana. To understand the function of BOR6, we analyzed a T-DNA insertion line for BOR6 and found that one line exhibits peculiar pattern of T-DNA segregation. This particular line carries T-DNA insertion in heterozygous but most of its selfed-progeny remain heterozygous. This peculiar segregation pattern is heritable. Although BOR6 is an boron transporter, this phenomenon is not dependent on boron nutrition status. This line carried a single copy of BOR6 and BOR6-T-DNA, suggesting that this phenomenon is caused through an allelic interaction.
