Tetraneura ulmi (L.), a member of Eriosomatinae subfamily, is one of the gall-forming aphids occurring on elms. Sap-sucking behaviour of founding mothers results in the formation of new plant organs. This study documents the changes in the content of plant biogenic amines (putrescine, cadaverine, spermidine, tryptamine, spermine and histamine) and key enzymes of their biosynthesis: lysine decarboxylase (LDC), tyrosine decarboxylase and ornithine decarboxylase (ODC) in galls and other parts of Siberian elm (Ulmus pumila L.) leaves during the galling process. The direction and intensity of these changes for particular amines and enzymes were dependent on the stage of gall development and part of the galling leaf. Generally, the amine content tended to increase in gall tissues during the 1st and 2nd period of the galling process and decreased in later phases. LDC and ODC activities were markedly enhanced, especially in gall tissues at the initial stage of the galling process.
榆四脉绵蚜（Tetraneura ulmi (L.)）是绵蚜亚科的成员之一，是在榆树上形成虫瘿的蚜虫之一。初建蚜母的刺吸行为会导致新植物器官的形成。本研究记录了在虫瘿形成过程中，西伯利亚榆（Ulmus pumila L.）叶片的虫瘿及其他部位中植物生物胺（腐胺、尸胺、亚精胺、色胺、精胺和组胺）含量的变化以及其生物合成的关键酶：赖氨酸脱羧酶（LDC）、酪氨酸脱羧酶和鸟氨酸脱羧酶（ODC）的变化。这些特定胺类和酶的变化方向和强度取决于虫瘿发育阶段和形成虫瘿叶片的部位。一般来说，在虫瘿形成过程的第一和第二阶段，虫瘿组织中的胺含量趋于增加，而在后期则下降。LDC和ODC的活性显著增强，尤其是在虫瘿形成过程初始阶段的虫瘿组织中。
