玉米橙子叶蝉Cicadulina bipunctata（半翅目：叶蝉科）在禾本科的多种植物上诱导以生长发育迟缓和严重的叶脉肿胀为特征的虫瘿。以往的研究表明，虫瘿不是在取食部位诱导的，而是在取食过程中远处新伸展的叶片上诱导的，这强烈表明叶蝉注入的某些化学物质影响了叶原基。探讨C. bipunctata，我们研究了植物对叶蝉取食的生理反应。我们进行了高通量和全面的植物激素分析，使用LC-ESI-MS/MS。脱落的玉米叶片含有较高的脱落酸（ABA）和反式玉米素（tZ）的含量和较低的赤霉素（GA1和GA4）比ungalled玉米叶片。叶蝉处理显著提高了伸展叶片中ABA和tZ的含量，降低了GA1和GA4的含量。在去除叶蝉后，伸展叶中tZ和赤霉素的含量很快就接近于对照值。去除叶蝉后ABA含量逐渐降低。在叶蝉处理的抗性玉米品种叶片上没有观察到这种激素变化。虫瘿叶片的含水量显著低于对照叶片，说明虫瘿叶片受到了水分胁迫，ABA含量升高可能是其原因之一。这些结果表明，ABA、tZ和赤霉素与叶蝉对感病玉米品种的虫瘿诱导有关。
The maize orange leafhopper Cicadulina bipunctata (Hemiptera: Cicadellidae) induces galls characterized by growth stunting and severe swelling of leaf veins on various plants of Poaceae. Previous studies revealed that galls are induced not on feeding site but on distant, newly extended leaves during the feeding, and strongly suggested that some chemicals injected by the leafhopper affect at the leaf primordia. To approach the mechanism underlying gall induction by C. bipunctata, we examined physiological response of plants to feeding by the leafhopper. We performed high-throughput and comprehensive plant hormone analyses using LC-ESI-MS/MS. Galled maize leaves contained higher contents of abscisic acid (ABA) and trans-Zeatin (tZ) and lower contents of gibberellins (GA1 and GA4) than ungalled maize leaves. Leafhopper treatment significantly increased ABA and tZ contents and decreased GA1 and GA4 contents in extending leaves. After the removal of leafhoppers, contents of tZ and gibberellins in extending leaves soon became similar to the control values. ABA content was gradually decreased after the removal of leafhoppers. Such hormonal changes were not observed in leafhopper treatment on leaves of resistant maize variety. Water contents of galled leaves were significantly lower than control leaves, suggesting water stress of galled leaves and possible reason of the increase in ABA content. These results imply that ABA, tZ, and gibberellins are related to gall induction by the leafhopper on susceptible variety of maize.
