Abstract The argininosuccinate lyase (ASL) gene of Chlamydomonas reinhardtii has been cloned using four oligonucleotide probes corresponding to highly conserved regions of the ASL polypeptide sequence. The identity of the gene was confirmed by partial sequencing. It is unique, contains several introns and spans a region less than 7.8 kb that includes highly repetitive sequences. Using a particle gun, a reliable nuclear transformation system has been established by complementing three mutants deficient in ASL activity with the wild-type ASL gene. Analysis of the transformants reveals variable patterns of integration of the transforming DNA into the nuclear genome. Previous work has mapped the mutations in the mutants arg2 and arg7 to either end of the ARG7 locus 1.0 to 1.6 recombination map units apart. Our transformation results show that these two mutations are located within a region of 7.8 kb. This allows for the first correlation of the recombination map and the molecular map at the ARG7 locus and indicates a high recombination frequency in this region of the nuclear genome.
