Abstract
The alcohol dehydrogenase (Adh) gene family is much more complex in Pi nus banksiana than in angiosperms, with at least seven expressed genes organized as two tightly linked clusters. Intron number and position are highly conserved between P. banksiana and angiosperms. Unlike angi osperm Adh genes, numerous duplications, as large as 217 bp, were obse rved within the noncoding regions of P. banksiana Adh genes and may be a common feature of conifer genes. A high frequency of duplication ov er a wide range of scales may contribute to the large genome size of c onifers.
