Novel kind of cell wall-degrading enzyme found in Aphelenchoides besseyi, the causal agent of white tip in rice.
Cooperation between laboratories from Japan, United Kingdom and The Netherlands resulted in the characterization of the transcriptome of a notorious plant-parasitic nematode in rice, Aphelenchoides besseyi. Such a transcriptome will tell us what kind of proteins an organism uses to successfully infect and parasitize rice. We found a kind of cellulase, an enzyme used by a parasite to enter its host, that is quite unusual for most plant-parasitic nematodes. This information suggests for a relatively close relationship between this organism and the causal agent of pine wilt, Bursaphelenchus xylophilus, and contributes to a better understanding of the parasitic behavior of this nematode.
