Gramineae root-knot nematode effector MgMO603 and application thereof

The invention discloses a Meloidogyne mimichaeli effector MgMO603 and an application of the Meloidogyne mimichaeli effector The amino acid sequence of the Meloidogyne miscaceae effector MgMO603 is shown as SEQ ID NO: 2, the coding nucleotide sequence of the Meloidogyne miscaceae effector MgMO603 is shown as SEQ ID NO: 1, and when the Meloidogyne miscaceae effector MgMO603 is expressed in the dorsal esophageal gland of Meloidogyne miscaceae, nematodes can be promoted to parasitize to host plants. The MgMO603-RNAi transgenic rice constructed by utilizing an RNAi technology has obvious root-knot nematode resistance, and the MgMO603 overexpression transgenic rice is more serious in nematode infection; it is shown that the effector MgMO603 can promote parasitism of the gramineae meloidogyne to the rice, transgenic rice with the remarkable meloidogyne resistance can be constructed based on the effector, and the MgMO603 has important application value and prospects in the aspect of prevention and control of the gram
