Certain amino and fatty acids play essential role in plant–herbivore interactions and also act as precursors for various plant defense compounds. Therefore, we carried out amino and fatty acid profiles of seedlings of different specialty maize genotypes viz., quality protein maize (high lysine and tryptophan contents in the kernels), sweet corn, white kernel and yellow kernel, and their fed Chilo partellus larvae to understand their contribution in plant defense. The larval and pupal weights, larval survival, adult emergence, and antibiosis indices of C. partellus were significantly lower on white and yellow kernel than that on sweet corn and quality protein maize genotypes. The amino and fatty acid contents varied significantly in the seedlings of test maize genotypes and in their fed C. partellus larvae. Amounts of aspartic acid, glycine, histidine, phenylalanine, proline, serine, and threonine were significantly lower in the seedlings of white kernel as compared to other maize genotypes. However, the amounts of these amino acids were significantly higher in the C. partellus larvae fed on white kernel as compared to those fed on other maize genotypes. Furthermore, amounts of basic, aliphatic, and cyclic amino acids were also lower in the seedlings of white kernel genotypes and higher in their fed C. partellus larvae as compared to other test maize genotypes and their fed insect larvae. The increase or decrease in myristic, cinnamic, linoleic, stearic, methyl-11-eicosanoate, and margaric acid contents in the maize seedlings and their fed C. partellus larvae followed consistent trend. Myristic and stearic acids were significantly higher in the seedlings of white kernel than other maize genotypes. Amino acids viz., aspartic acid, glycine, histidine, lysine, phenylalanine, proline, serine, and threonine; and the fatty acid, stearic acid in the test maize genotypes showed significant association with various growth and development indices, and contributed to 100% variability in antibiosis against C. partellus, which could be used as biomarkers to identify spotted stem borer-resistant maize genotypes.

某些氨基酸和脂肪酸在植物与食草动物的相互作用中起着重要作用，并且还充当各种植物防御化合物的前体。因此，我们对不同特种玉米基因型的幼苗进行了氨基酸和脂肪酸分析，即。，优质蛋白质玉米（谷粒中赖氨酸和色氨酸含量高）、甜玉米、白谷粒和黄谷粒，以及它们喂养的Chilo partellus幼虫，以了解它们在植物防御中的贡献。C. partellus的幼虫和蛹重量、幼虫存活、成虫出现和抗菌指数白仁和黄仁的 显着低于甜玉米和优质蛋白玉米基因型。试验玉米基因型的幼苗和饲喂的C. partellus幼虫的氨基酸和脂肪酸含量差异很大。与其他基因型玉米相比，白仁幼苗中天冬氨酸、甘氨酸、组氨酸、苯丙氨酸、脯氨酸、丝氨酸和苏氨酸的含量显着降低。然而，与饲喂其他玉米基因型的幼虫相比，饲喂白籽粒的C. partellus幼虫中这些氨基酸的含量显着更高。此外，白仁基因型幼苗中碱性、脂肪族和环状氨基酸的含量也较低，而饲喂的C. partellus 中的含量较高幼虫与其他测试玉米基因型及其喂养的昆虫幼虫相比。玉米幼苗及其饲喂的C. partellus幼虫中肉豆蔻酸、肉桂酸、亚油酸、硬脂酸、甲基-11-二十烷酸和十七烷酸含量的增减趋势一致。肉豆蔻酸和硬脂酸在白仁幼苗中显着高于其他基因型玉米。氨基酸即。、天冬氨酸、甘氨酸、组氨酸、赖氨酸、苯丙氨酸、脯氨酸、丝氨酸和苏氨酸；测试玉米基因型中的脂肪酸、硬脂酸显示出与各种生长和发育指标显着相关，并有助于对C. partellus 的抗生素产生 100% 的变异性，可用作生物标志物来识别斑点茎螟抗性玉米基因型。
