The TIR-Type NLR Protein Is Involved in the Regulation of Phelipanche aegyptiaca Resistance in Cucumis melo

Phelipanche aegyptiaca is an obligate holoparasite that causes serious negative effects on crop growth and productivity, effective control of which difficult due to its unique biological characteristics. In this study, we performed a comparative transcriptome analysis resistant susceptible Cucumis melo cultivars (KR1326 K1237) inoculated with P. aegyptiaca. CmNLR (encodes TIR-type NLR protein, consistently highly expressed in KR1326 roots) CmNLRh (homologous gene CmNLR) were cloned overexpressed K1237 roots verify whether the protein can enhance C. resistance The variations enzymes related active oxygen metabolism further detected transformed roots. results showed (1) some differentially genes (DEGs) enriched pathways associated scavenging; (2) several DEGs encoded transcription factors, calcium channel proteins, receptor-like proteins upregulated roots; (3) complete prevented from connecting vascular system (4) stronger burst scavenging capacity We herein demonstrated confers provided clues for finding new direction host against parasitic plants shed light cultivation varieties
