Additional file 8: Table S4. Putative phytonematode effectors identified in H. avenae. a Putative key genes based on blastx searching against other phytonematode effectors. b Carbohydrate-active enzymes with homology to those of other phytonematodes. * # CCN ESTs, number of ESTs in Cereal cyst nematode H. avenae. ‘Pre’ means significantly high expression in pre-parasitic stage; ‘Pre*’ means coding by singleton in pre-parasitic library. The singleton might be the gene with low expression and was sequenced only once. CBM, carbohydrate binding module; GH, glycoside hydrolase; GT, glycosyl transferase; PL, polysaccharide lysate. NR means non-redundant GenBank proteins database.
