凝集素是植物中普遍存在的蛋白质，在多种生物过程中发挥重要作用，如植物防御和细胞信号传导。尽管自2009年以来黄瓜（Cucumis sativus L.）基因组序列的可用性，但关于黄瓜中凝集素的发生知之甚少。本研究在黄瓜基因组中鉴定并定位了10个不同凝集素家族的146个推测的凝集素基因。结构域结构分析表明，大多数凝集素基因序列包含多个结构域，其中凝集素结构域与其他结构域相连接，从而形成嵌合凝集素序列，编码具有双重活性的蛋白质。本研究提供了黄瓜中凝集素基序的概述，并将有助于了解它们潜在的生物学作用。(C) 2016 Elsevier Masson SAS。版权所有。
Lectins are ubiquitous proteins in plants and play important roles in a diverse set of biological processes, such as plant defense and cell signaling. Despite the availability of the Cucumis sativus L. genome sequence since 2009, little is known with respect to the occurrence of lectins in cucumber. In this study, a total of 146 putative lectin genes belonging to 10 different lectin families were identified and localized in the cucumber genome. Domain architecture analysis revealed that most of these lectin gene sequences contain multiple domains, where lectin domains are linked with other domains, as such creating chimeric lectin sequences encoding proteins with dual activities. This study provides an overview of lectin motifs in cucumber and will help to understand their potential biological role(s). (C) 2016 Elsevier Masson SAS. All rights reserved.
