与RCD-ONEs（SROs）类似，SROs包含一个小的植物特异性基因家族，其在调节许多生长和发育过程以及对环境胁迫的响应中发挥重要作用。然而，对芝麻（Sesamum indicum L.）是有限的。在这项研究中，在芝麻基因组中鉴定了四个SRO基因。系统发育分析表明，10种植物的64个SRO可分为两个类群（类群I和类群II）。转录组数据揭示了SiSRO在各种组织中的不同表达模式。表达分析表明，第二组SROs，特别是SiSRO 2b，表现出更强的响应各种非生物胁迫和植物激素比第一组，这意味着他们在响应环境刺激和激素信号的关键作用。此外，共表达网络和蛋白质-蛋白质相互作用网络表明SiSROs与广泛的胁迫反应相关。此外，含有SiSRO 2b的转基因酵母表现出对盐、渗透压和氧化胁迫的耐受性提高，表明SiSRO 2b可以赋予转基因酵母多种耐受性。本研究不仅为SiSRO基因家族的进一步功能研究奠定了基础，而且为芝麻非生物胁迫抗性的遗传改良提供了有价值的候选基因。
SIMILAR TO RCD-ONEs (SROs) comprise a small plant-specific gene family which play important roles in regulating numerous growth and developmental processes and responses to environmental stresses. However, knowledge of SROs in sesame (Sesamum indicum L.) is limited. In this study, four SRO genes were identified in the sesame genome. Phylogenetic analysis showed that 64 SROs from 10 plant species were divided into two groups (Group I and II). Transcriptome data revealed different expression patterns of SiSROs over various tissues. Expression analysis showed that Group II SROs, especially SiSRO2b, exhibited a stronger response to various abiotic stresses and phytohormones than those in Group I, implying their crucial roles in response to environmental stimulus and hormone signals. In addition, the co-expression network and protein-protein interaction network indicated that SiSROs are associated with a wide range of stress responses. Moreover, transgenic yeast harboring SiSRO2b showed improved tolerance to salt, osmotic and oxidative stress, indicating SiSRO2b could confer multiple tolerances to transgenic yeast. Taken together, this study not only lays a foundation for further functional dissection of the SiSRO gene family, but also provides valuable gene candidates for genetic improvement of abiotic stress tolerance in sesame.
