Abstract

Root nodules collected from the non-leguminous plant Trema cannabina Lour. grown under natural field conditions were examined for the presence of leghaemoglobin. No trace of any soluble haemoglobin-like compound could be detected by spectrophotometric analysis or molecular weight comparison studies, although a small amount of soluble haemoprotein with peroxidase activity was isolated. Possible alternatives to the possession of a leghaemoglobin in non-legume/Rhizobium N2-fixing associations are discussed.

摘要

对在自然田间条件下生长的非豆科植物大麻叶苎麻（Trema cannabina Lour.）所采集的根瘤进行了检测，以确定其中是否存在豆血红蛋白。通过分光光度分析或分子量比较研究，未检测到任何可溶性血红蛋白样化合物的踪迹，尽管分离出了少量具有过氧化物酶活性的可溶性血红素蛋白。本文讨论了非豆科植物/根瘤菌固氮联合体中拥有豆血红蛋白的可能替代物。
