Abstract

The salicylic acid receptor NPR1 (nonexpressor of pathogenesis-related genes) and its paralogues NPR3 and NPR4 are master regulators of plant immunity. Commercial strawberry ( × ) is a highly valued crop vulnerable to various pathogens. Historic confusions regarding the identity of -like genes have hindered research in strawberry resistance. In this study, the comprehensive identification and phylogenic analysis unraveled this family, harboring 6, 6, 5, and 23 members in , , , and × , respectively. These genes were clustered into three clades, with each diploid member matching three to five homoalleles in × . Despite the high conservation in terms of gene structure, protein module, and functional residues/motifs/domains, substantial divergence was observed, hinting strawberry NPR proteins probably function in ways somewhat different from . RT-PCR and RNAseq analysis evidenced the transcriptional responses of and to . Extended expression analysis for strawberry -likes helped to us understand how strawberry orchestrate the NPRs-centered defense system against . The cThe current work supports that FveNPR1 and FxaNPR1a, as well as FveNPR31 and FxaNPR31a-c, were putative functional orthologues of AtNPR1 and AtNPR3/4, respectively. These findings set a solid basis for the molecular dissection of biological functions of strawberry -like genes for improving disease resistance.

摘要

水杨酸受体NPR1（病程相关基因非表达子）及其旁系同源物NPR3和NPR4是植物免疫的主要调节因子。商业草莓（×）是一种高价值作物，易受多种病原体侵害。关于类似基因身份的历史混淆阻碍了草莓抗性研究。在本研究中，全面的鉴定和系统发育分析揭示了该家族，在森林草莓（Fragaria vesca）、黄毛草莓（Fragaria nilgerrensis）、五叶草莓（Fragaria pentaphylla）和商业草莓（×）中分别含有6个、6个、5个和23个成员。这些基因被聚类为三个分支，每个二倍体成员在商业草莓中匹配三到五个同源等位基因。尽管在基因结构、蛋白质模块和功能残基/基序/结构域方面具有高度保守性，但仍观察到显著差异，这表明草莓NPR蛋白的功能方式可能与拟南芥有所不同。RT-PCR和RNAseq分析证明了森林草莓和黄毛草莓中NPR基因对水杨酸的转录反应。对草莓NPR类似基因的扩展表达分析有助于我们了解草莓如何协调以NPR为中心的防御系统来抵御病原体。目前的工作支持FveNPR1和FxaNPR1a以及FveNPR31和FxaNPR31a-c分别是拟南芥AtNPR1和AtNPR3/4的推定功能直系同源物。这些发现为深入剖析草莓NPR类似基因的生物学功能以提高抗病性奠定了坚实基础。
