"Tritrophic interactions allow plants to recruit natural enemies for protection against herbivory. Here\r\nwe investigated genetic variability in induced responses to stemborer egg-laying in maize Zea mays\r\n(L.) (Poaceae). We conducted a genome wide association study (GWAS) of 146 maize genotypes\r\ncomprising of landraces, inbred lines and commercial hybrids. Plants were phenotyped in bioassays\r\nmeasuring parasitic wasp Cotesia sesamiae (Cameron) (Hymenoptera: Braconidae) attraction\r\nto volatiles collected from plants exposed to stemborer Chilo partellus (Swinhoe) (Lepidoptera:\r\nCrambidae) eggs. Genotyping-by-sequencing was used to generate maize germplasm SNP data for\r\nGWAS. The egg-induced parasitoid attraction trait was more common in landraces than in improved\r\ninbred lines and hybrids. GWAS identified 101 marker-trait associations (MTAs), some of which were\r\nadjacent to genes involved in the JA-defence pathway (opr7, aos1, 2, 3), terpene biosynthesis (fps3,\r\ntps2, 3, 4, 5, 7, 9, 10), benzoxazinone synthesis (bx7, 9) and known resistance genes (e.g. maize insect\r\nresistance 1, mir1). Intriguingly, there was also association with a transmembrane protein kinase\r\nthat may function as a receptor for the egg elicitor and other genes implicated in early plant defence\r\nsignalling. We report maize genomic regions associated with indirect defence and provide a valuable\r\nresource for future studies of tritrophic interactions in maize. The markers identified may facilitate\r\nselection of indirect defence by maize breeders."^^ . "2020-07" . . . "10" . "1" . . "Nature Research"^^ . . . "Scientific Reports (TSI)"^^ . . .
