The lectins of associative nitrogen-fixing bacteria Azospirillum brasilense Sp7 and its mutant A. brasilense Sp7.2.3 were shown to have different effects on the components of the wheat seedling root signal system, namely to regulate the levels of cAMP, nitric oxide, diacylglycerol, and salicylic acid, as well as to induce the activities of superoxide dismutase and lipoxygenase. Our results make it possible to consider azospirilla lectins as inducers of the signal systems in wheat seedling roots, since they cause development of several flows of primary signals. These data are of general biological importance, since lectins are present in all living organisms and most ot the functions of lectins remain insufficiently understood.
研究表明,联合固氮菌巴西固氮螺菌Sp7及其突变体巴西固氮螺菌Sp7.2.3的凝集素对小麦幼苗根系信号系统的组成成分具有不同影响,即调节环磷酸腺苷(cAMP)、一氧化氮、二酰基甘油和水杨酸的水平,以及诱导超氧化物歧化酶和脂氧合酶的活性。我们的研究结果使人们有可能将固氮螺菌凝集素视为小麦幼苗根系信号系统的诱导剂,因为它们会引发多种初级信号流的产生。这些数据具有普遍的生物学意义,因为凝集素存在于所有生物体中,而凝集素的大多数功能仍未得到充分了解。
