We previously isolated a Brassica juncea cDNA encoding BjCHI1, a novel chitinase with two chitin-binding domains. Synthesis of its mRNA is induced by wounding, methyl jasmonate treatment, Aspergillus niger infection and caterpillar (Pieris rapae) feeding, suggesting that the protein has a role in
We have cloned a 1.3 kb Brassica juncea cDNA encoding BjCHI1, a novel acidic chitinase with two chitin-binding domains that shows 62% identity to Nicotiana tabacum Chia1 chitinase. BjCHI1 is structurally unlike Chia1 that has one chitin-binding domain, but resembles Chia5 chitinase UDA1, the
