<b>Map positions of</b><i><b>SFR</b></i><b>genes in relation to other freezing‐related genes of</b><i><b>Arabidopsis thaliana</b></i>

Abstract

We determined the map positions of seven SFR genes and compared them to the positions of 51 genes suspected of involvement in freezing tolerance in Arabidopsis thaliana. The SFR genes were recognized by the freezing sensitivity of mutants; the others (including 14 whose map positions we have determined) were genes whose expression is induced by low temperature, genes involved in abscisic acid (ABA) biosynthesis and perception, and genes involved in tolerance of oxidative stress. The comparison of map positions indicated a limited set of potential identities, some of which were eliminated by further mapping or by an allelism test.
