Identification of the gene whose mutation leads to the morphological changes in the hypocotyl of <Emphasis Type="Italic">Arabidopsis thaliana</Emphasis>

The results of genetic and molecular genetic analysis of line 176 of Arabidopsis thaliana with reduced hypocotyls obtained from a previously developed collection of insertion mutants, are presented. The examined mutation proved to be recessive and based on a single insertion of the T-DNA vector pLD3 into the A. thaliana genome. Computer-aided analysis of the amplified in TAIL-RCR DNA region adjacent to the left border of the insertion revealed a putative site of T-DNA insertion, the 2.5-kb At2g09920 gene located in the long arm of chromosome 2, near the centromere.Translated from Genetika, Vol. 41, No. 2, 2005, pp. 166–170.Original Russian Text Copyright © 2005 by Ogarkova, Tomilov, Tomilova, Pogorelko, Tarasov.
