Comparing available Poaceae defensins with sugarcane ESTs, a putative defensin gene was identified in sugarcane and cloned from genomic sugarcane DNA.

The deduced encoded peptide shows the structure and amino acid composition typical of other plant defensins. Using RTPCR, defensin expression in sugarcane and differences between “normal” and infected sugarcane were evidenced.

More about this publication?
  • Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
