褐飞虱在适应抗性水稻品种“IR26”过程中的氨基酸含量变化

Variability of free amino acid content in brown planthopper Nilaparvata lugens (Stal) during adaptation to resistant rice variety “IR26”

  • 摘要: 本试验研究了褐飞虱在适应抗性水稻品种“IR26”过程中体内游离氨基酸含量的变化规律,结果表明,“IR26”植株的叶鞘和伤流液中氨基酸总量分别比感虫水稻品种“TN1”植株的低3.78%和3.05%。除苯丙氨酸和赖氨酸外,褐飞虱在“IR26”上取食第2代时体内其他氨基酸含量均升高,从第3代开始下降。饲养在“TN1”上的褐飞虱转移到“IR26”上取食后,其蜜露中氨基酸除天冬氨酸、谷氨酸和胱氨酸外,其他游离氨基酸含量均上升。而在“IR26”上取食3代的褐飞虱转移到“TN1”上取食,其蜜露中的苏氨酸、缬氨酸、精氨酸、天冬氨酸、丝氨酸、谷氨酸和甘氨酸含量下降,但氨基酸总量相差不大。

     

    Abstract: The contents of free amino acids in brown planthopper (BPH) Nilaparvata lugens Stal were determined during its adaptation stage to resistant rice variety “IR26”. The results show that the contents of total free amino acids (TFAA) and essential amino acids (EAA) in leaf sheath and sap flow of “IR26” drop by 3.78% and 3.05% below those in the susceptible variety “TN1”. Brachypterous BPH female adults feeding on “IR26” obtains more TFAA and EAA, except phenylalanine and lysine in the second generation. However, TFAA and EAA contents decrease in the third generation. The contents of other free amino acids in female adult honeydew increase, except aspartic acid, glutamic acid and cystine, when BPH is transferred from “TN1” to “IR26”. When the BPH fed with “IR26” for three generations are transferred to “TN1”, the contents of threonine, valine, arginine, aspartic acid, serine, glutamic acid and glycine become lower than in those feeding exclusively on “IR26”. No obvious difference exists in TFAA contents between BPH feeding on “IR26” and “TN1”.
