The novel classes of plant pathogenesis-related (PR) proteins identified during the last decade also include novel peptide families. This review specifically focuses on these pathogenesis-related peptides, including proteinase inhibitors (PR-6 family), plant defensins (PR-12 family), thionins (PR-13 family) and lipid transfer proteins (PR-14 family). For each family of PR peptides, the general features concerning occurrence, expression and possible functions of their members are described. Next, more specifically the occurrence of each PR peptide family in the model plant Arabidopsis thaliana is discussed. Single-gene studies performed on particular gene members of a PR peptide family are reported. In addition, expression data of yet undescribed gene members of that particular PR peptide family are presented by consultation of publicly available micro-array databases. Finally an update is provided on the potential role of these PR peptides in A. thaliana, with a focus on their possible involvement in plant defense.
在过去十年中鉴定出的新型植物病程相关（PR）蛋白类别还包括新型肽家族。本综述特别关注这些病程相关肽，包括蛋白酶抑制剂（PR-6家族）、植物防御素（PR-12家族）、硫堇（PR-13家族）和脂质转移蛋白（PR-14家族）。对于每个PR肽家族，描述了其成员在发生、表达和可能功能方面的一般特征。接下来，更具体地讨论了每个PR肽家族在模式植物拟南芥中的存在情况。报告了对PR肽家族特定基因成员进行的单基因研究。此外，通过查阅公开可用的微阵列数据库，展示了该特定PR肽家族尚未描述的基因成员的表达数据。最后，提供了关于这些PR肽在拟南芥中潜在作用的最新信息，重点是它们可能参与植物防御的情况。
