Abstract

Ginger (Zingiber officinale Roscoe) is an important plant used worldwide for medicine and food. The R2R3-MYB transcription factor (TF) family has essential roles in plant growth, development, and stresses resistance, and the number of genes in the family varies greatly among different types of plants. However, genome-wide discovery of ZoMYBs and gene responses to stresses have not been reported in ginger. Therefore, genome-wide analysis of R2R3-MYB genes in ginger was conducted in this study. Protein phylogenetic relations and conserved motifs and chromosome localization and duplication, structure, and cis-regulatory elements were analyzed. In addition, the expression patterns of selected genes were analyzed under two different stresses. A total of 299 candidate ZoMYB genes were discovered in ginger. Based on groupings of R2R3-MYB genes in the model plant Arabidopsis thaliana (L.) Heynh., ZoMYBs were divided into eight groups. Genes were distributed across 22 chromosomes at uneven densities. In gene duplication analysis, 120 segmental duplications were identified in the ginger genome. Gene expression patterns of 10 ZoMYBs in leaves of ginger under abscisic acid (ABA) and low-temperature stress treatments were different. The results will help to determine the exact roles of ZoMYBs in anti-stress responses in ginger.

生姜中 R2R3-MYB 家族基因的全基因组鉴定及基因对胁迫的响应。

生姜（Zingiber officinale Roscoe）是世界上重要的药用和食用植物。R2R3-MYB 转录因子（TF）家族在植物的生长、发育和抗逆性方面发挥着重要作用，该家族的基因数量在不同类型的植物中差异很大。然而，在生姜中发现全基因组的 ZoMYBs 和基因对胁迫的反应尚未见报道。因此，本研究对生姜中的 R2R3-MYB 基因进行了全基因组分析。分析了蛋白质的系统发育关系和保守基序以及染色体定位和重复、结构和顺式调控元件。此外，还分析了所选基因在两种不同胁迫下的表达模式。在生姜中总共发现了 299 个候选 ZoMYB 基因。根据模式植物拟南芥（Arabidopsis thaliana (L.) Heynh.）中 R2R3-MYB 基因的分组，ZoMYB 被分为八组。基因以不均匀的密度分布在 22 条染色体上。在基因重复分析中，发现生姜基因组中有 120 个片段重复。在脱落酸（ABA）和低温胁迫处理下，生姜叶片中 10 个 ZoMYB 的基因表达模式有所不同。这些结果将有助于确定 ZoMYBs 在生姜抗胁迫反应中的确切作用。
