Table_2_miRNAs and lncRNAs in tomato: Roles in biotic and abiotic stress responses.docx

Plants are continuously exposed to various biotic and abiotic stresses in the natural environment. To cope with these stresses, they have evolved a multitude of defenses mechanisms. With the rapid development of genome sequencing technologies, a large number of non-coding RNA (ncRNAs) have been identified in tomato, like microRNAs (miRNAs) and long non-coding RNAs (lncRNAs). Recently, more and more evidence indicates that many ncRNAs are involved in plant response to biotic and abiotic stresses in tomato. In this review, we summarize recent updates on the regulatory roles of ncRNAs in tomato abiotic/biotic responses, including abiotic (high temperature, drought, cold, salinization, etc.) and biotic (bacteria, fungi, viruses, insects, etc.) stresses. Understanding the molecular mechanisms mediated by ncRNAs in response to these stresses will help us to clarify the future directions for ncRNA research and resistance breeding in tomato.

植物在自然环境中始终面临各类生物胁迫与非生物胁迫。为应对此类胁迫，植物演化出了多种防御机制。随着基因组测序技术的飞速发展，科研人员已在番茄中鉴定出大量非编码RNA（non-coding RNA，ncRNA），例如微小RNA（microRNA，miRNA）与长链非编码RNA（long non-coding RNA，lncRNA）。近年来，越来越多研究证据表明，番茄中的诸多ncRNA参与了植物对生物与非生物胁迫的应答过程。本综述总结了当前关于ncRNA在番茄应对生物及非生物胁迫过程中调控作用的最新研究进展，其中非生物胁迫涵盖高温、干旱、低温、盐渍化等类型，生物胁迫则包括细菌、真菌、病毒、昆虫等病原物与虫害。解析ncRNA介导的植物应对此类胁迫的分子机制，有助于明确番茄ncRNA研究与抗病抗逆育种的未来发展方向。
