Plant parasitic nematodes secrete effector proteins to parasitize hosts successfully. Of these proteins, serine carboxypeptidases have critical roles in pathogenicity. This study investigated the role of new effector AbSCP1 in Aphelenchoides besseyi pathogenicity. In situ hybridization and qRT-PCR analyses indicated that AbSCP1 was exclusively expressed in the esophageal glands and upregulated in juveniles. Subcellular localization assays indicated that the protein was expressed in the nucleus. The ability to hydrolyze C-terminal amino acid residues was proven for AbSCP1. Moreover, RNAi significantly reduced the expression of AbSCP1 and RNAi-treated nematodes\' reproductive potential. Pathogenicity assays on rice showed that RNAi-treated nematodes were less pathogenic than the untreated control groups. These results suggest the important role of AbSCP1 in the A. besseyi infection process.

脂肪肝是奶牛围产期常见多发的营养代谢性疾病,特别是高产奶牛的发病率极高,常常伴随难产,并诱发多种炎性反应等疾病.此外,还会导致奶牛产奶量减少和平均寿命降低,给奶牛养殖业带来巨大损失.因此探究围产期奶牛脂肪肝的发展进程,对于切实提升高产奶牛的经济价值,和对奶牛脂肪肝的预防与治疗有着重要意义.本文对奶牛围产期脂肪肝的研究情况进行了综述.
