Abstract

The small regulatory C-TERMINALLY ENCODED PEPTIDE (CEP) peptide family plays crucial roles in plant growth and stress response. However, little is known about this peptide family in Brassica species. Here, we performed a systematic analysis to identify the putative L. () gene family. In total, 27 genes were identified and they were classified into four subgroups based on the CEP motifs similarity. genes displayed distinct expression patterns in response to both developmental and several environmental signals, suggesting their broad roles during development. Furthuremore, the synthetic BrCEP3 peptide accelerated primary root growth in a hydrogen peroxide (HO) and Ca dependent manner. In summary, our work will provide fundamental insights into the physiological function of CEP peptides during development.

摘要

小调节 C 端编码肽（CEP）肽家族在植物生长和应激反应中发挥着关键作用。然而，关于拟南芥属物种中的这种肽家族知之甚少。在这里，我们进行了系统分析以鉴定假定的 L. () 基因家族。总共鉴定出 27 个基因，并根据 CEP 基序的相似性将它们分为四个亚组。基因显示出对发育和几种环境信号的不同表达模式，表明它们在发育过程中具有广泛的作用。此外，合成的 BrCEP3 肽以 H2O2（HO）和 Ca 依赖的方式加速了主根的生长。总之，我们的工作将为 CEP 肽在发育过程中的生理功能提供基础见解。
