植物肽在植物生长发育的各个方面发挥着重要作用。RTFL/DVL家族包括在陆地植物中广泛保守的小肽。在拟南芥中过表达的6个RTFL基因暗示了它们作为细胞增殖的负调控因子和作为植物体纵向轴沿着的位置线索的功能。目前，关于RTFL旁系同源基因在其他物种中的研究报道较少，陆地植物中RTFL成员的进化关系尚不清楚。本研究比较分析了22种陆生植物188个RTFL成员的氨基酸序列，鉴定出73个基序。所有RTFL成员可以分为四个分支，每个分支表现出特定的基序模式，表明在RTFL家族的独特的进化特征。与此假设一致，我们分析了两个RTFL成员从水稻和拟南芥中过表达他们在拟南芥，揭示了类似的表型暗示的RTFL家族的真双子叶植物和单子叶植物之间的保守功能，以及不同的表型和独特的功能。本文的在线版本（doi：10.1007/s10265-015-0703-1）包含补充材料，可供授权用户使用。
Plant peptides play important roles in various aspects of plant growth and development. The RTFL/DVL family includes small peptides that are widely conserved among land plants. Overexpression of six RTFL genes in Arabidopsis was suggestive of their functions as negative regulators of cell proliferation and as positional cues along the longitudinal axis of the plant body . At this time, few reports are available on RTFL paralogs in other species and the evolutionary relationship of RTFL members among land plants remains unclear. In this study, we compared and analyzed whole amino acid sequences of 188 RTFL members from 22 species among land plants and identified 73 motifs. All RTFL members could be grouped into four clades, and each clade exhibited specific motif patterns, indicative of unique evolutionary traits in the RTFL family. In agreement with this hypothesis, we analyzed two RTFL members from Oryza sativa and Arabidopsis by overexpressing them in Arabidopsis, revealing similar phenotypes suggestive of a conserved function of the RTFL family between eudicots and monocots, as well as different phenotypes and unique functions.
