摘要:

植物寄生线虫是一类专性活体寄生物,主要寄生植物根部,严重影响植物生长发育,给我国农业生产造成巨大的损失。钙网蛋白是一种定位于真核细胞内质网中的多功能蛋白,具有3个功能结构域:N-功能域、P-功能域、C-功能域。迄今已发现的植物寄生线虫钙网蛋白主要来自于南方根结线虫、禾谷孢囊线虫、水稻干尖线虫、香蕉穿孔线虫、马铃薯茎线虫和松材线虫等。本文通过对植物寄生线虫钙网蛋白的结构特点、体内转录位点、抑制防御反应和促进寄生等方面进行了综述,以加深对钙网蛋白在线虫侵染植物过程中功能的了解,为植物线虫病害防治方法提供理论基础。

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
