Abstract
Recent molecular genetic data suggest that cellulose synthase (CesA) genes coding for the enzymes that catalyze cellulose biosynthesis (CESAs) in Arabidopsis and other herbaceous plants belong to a large gene family. Much less is known about CesA genes from forest trees. To isolate new CesA genes from tree species, discriminative but easily obtainable homologous DNA probes are required. Hypervariable regions (HVRII) of CesA genes represent highly divergent DNA sequences that can be used to examine structural, expressional and functional relationships among CesA genes. We used a reverse transcriptase-polymerase chain reaction (RT-PCR)-based technique to identify HVRII regions from eight types of CesA genes and two types of CesA-like D (CslD) genes in quaking aspen (Populus tremuloides Michx.). Comparison of these aspen CESA/CSLD HVRII regions with the predicted proteins from eight full-length CesA/CslD cDNAs available in our laboratory and with searches for aspen CesA/CslD homologs in the recently released Populus trichocarpa Torr. & A. Gray. genome confirmed the utility of this approach in identifying several CesA/CslD gene members from the Populus genome. Phylogenetic analysis of 56 HVRII domains from a variety of plant species suggested that at least six distinct classes of CESAs exist in plants, supporting a previous proposal for renaming HVRII regions as class-specific regions (CSR). This method of CSR cloning could be applied to other crop plants and tree species, especially softwoods, for which the whole genome sequence is unlikely to become available in the near future because of the large size of these genomes.
