We determined the primary structure of a tobacco r-1,3-glucanase gene. The r-1,3-glucanase gene has a single large intron, and the intron separates coding regions of the signal peptide and the mature enzyme. Analysis of the 5'-flanking region sequence revealed an 11 bp GC-rich element with perfect h

✦ Synopsis
We have isolated cDNA clones representing mRNAs encoding chitinase and 1,3-fl-glucanase in cotton (Gossypium hirsutum L.) leaves. The chitinase clones were sequenced and found to encode a 28,806 Da protein with 71% amino acid sequence similarity to the SK2 chitinase from potato (Solanum tuberosum). The 1,3-fl-glucanase clones encoded a 37,645 Da protein with 57.6% identity to a 1,3-fl-glucanase from soybean (Glycine max). Northern blot

The molecular cloning of 1,3--glucanase-encoding genes from different yeast species was achieved by screening genomic libraries with DNA probes obtained by PCR-amplification using oligonucleotides designed according to conserved regions in the EXG1, EXG2 and SSG1 genes from Saccharomyces cerevisiae.
