Abstract:

Plant parasitic nematodes,as obligate living parasites,affect plant growth and development by infecting roots and cause huge losses in agricultural production in China. Calreticulin are multifunctional proteins which are located in the endoplasmic reticulum(ER)in eukaryotic cells. Calreticulin contains three structural functional domains:N-functional domain,P-functional domain,and C-functional domain. The calreticulin have been found in Meloidogyne incognita,Heterodera avenae,Aphelenchoides besseyi,Radopholus similis,Ditylenchus angustus,and Bursaphelenchus xylophilus. We summarized the structural characteristics,transcriptional sites in nematodes,suppression plant defense response and promoting parasitism of calreticulin from plant parasitic nematode. The insight into the function of calreticulin from plant parasitic nematode in infecting plants provide a theoretical basis for the prevention and controlling of plant parasitic nematode in China.

Key words: plant parasitic nematodes, calreticulin, plant immunity, developmental expression pattern, synthetic sites
