Abstract:

Root-knot nematode(Meloidogyne spp.)and cyst nematode(Heterodera spp.)are the two most harmful endoparasitic nematodes to the agricultural production. After the nematodes invading the plant,they absorb nutrients and complete their life cycle by forming giant cell or syncytia at the feeding sites. Plants establish a good interaction with invaded nematodes by controlling the levels of auxin,ethylene,cytokinin,gibberellin,abscisic acid and other plant hormones. This paper reviews the establishment and formation of nematode feeding sites,the expression and regulation of plant hormone-related genes in nematode feeding sites,and the effects of plant hormones on the establishment and formation of nematode feeding sites,as well as discusses the issues related to the synergistic effect of plant hormones on the feeding sites of nematodes and the latest research,aiming to reveal the effects of plant hormones on the establishment and development of feeding sites of plant parasitic nematodes and to provide references for the integrated management of crop nematode diseases.

Key words: cyst nematodes, root-knot nematodes, feeding site of nematodes, plant hormones, plant hormone regulation
