To sustain plants' postembryonic growth and development in a structure of cells fixed in cell walls, a tightly controlled short distance cell-cell communication is required. The focus on phytohormones, such as auxin, has historically overshadowed the importance of small peptide signals, but it is becoming clear that secreted peptide signals are important in cell-cell communication to coordinate and integrate cellular functions. However, of the more than 1000 potential secreted peptides, so far only very few have been functionally characterized or matched to a receptor. Here, we will describe our current knowledge on how small peptide signals can be identified, how they are modified and processed, which roles they play in Arabidopsis thaliana development, and through which receptors they act.
为了在细胞壁固定的细胞结构中维持植物的胚胎后生长和发育，需要进行严格控制的短距离细胞间通讯。人们一直关注植物激素，如生长素，而忽略了小肽信号的重要性，但现在越来越清楚的是，分泌的肽信号在协调和整合细胞功能的细胞间通讯中很重要。然而，在超过 1000 种潜在的分泌肽中，到目前为止，只有极少数被功能表征或与受体匹配。在这里，我们将描述我们目前对如何识别小肽信号、它们如何被修饰和加工、它们在拟南芥发育中扮演的角色以及它们通过哪些受体起作用的认识。
