摘要

红砂 ( Reaumuria soongorica) 是我国西北荒漠区广泛分布的耐盐旱生小灌木, 具有极强的生境适应性, 是研究植物抗逆分子机制的理想材料。以红砂基因组为参考, 鉴定其 AP2/ ERF基因家族成员, 并分析其系统发育、基因结构、保守基序、顺式作用元件、基因复制事件以及该家族成员在盐胁迫下的表达模式。结果表明, 红砂基因组中有70个 AP2/ ERF基因, 系统发育分析显示其可分为 AP2ERFDREBRAV亚家族; 其启动子区含有多种光响应、胁迫响应、生长发育和激素响应等顺式作用元件。红砂 AP2/ ERF基因非均匀分布在其基因组的11条染色体上, 其中63个基因由不同基因复制事件演化而来, 全基因组复制和分散复制是该基因家族扩张的主导因素。在盐胁迫下, 红砂 AP2/ ERF基因呈现不同的表达模式, 6个基因显著差异表达, 可能在红砂响应盐胁迫过程中发挥积极作用。该研究从基因组水平鉴定和分析了红砂 AP2/ ERF基因家族的特征, 旨在为进一步解析其在逆境适应中的分子功能奠定基础。

Abstract

INTRODUCTION: Reaumuria soongorica, a perennial small shrub, is widely distributed in arid desert regions of northwestern China. It exhibits exceptional drought and salt tolerance, making it an ideal model for studying molecular mechanisms of plant stress resistance. RATIONALE: We used the R. soongorica genome as a reference to identify members of the AP2/ ERF gene family in this species, and analyzed their phylogeny, gene structure, conserved motifs, cis-acting elements, gene duplication events, as well as the expression patterns of these family members under salt stress. RESULTS: Seventy AP2/ ERF genes were identified from the R. soongorica genome. Phylogenetic analysis classified these genes into four subfamilies: AP2, ERF, DREB, and RAV. Cis-acting element analysis revealed multiple regulatory elements associated with light responsiveness, stress adaptation, growth regulation, and hormone signaling in the promoter regions of R. soongorica AP2/ ERF genes. These genes exhibited an uneven distribution across all 11 chromosomes of the R. soongorica genome, with 63 genes (90% of the total) originating from gene duplication events. Evolutionary analysis suggested that whole-genome duplication (WGD) and dispersed duplication were the primary drivers of family expansion. Under salt stress, AP2/ ERF genes showed divergent expression patterns in R. soongorica seedlings, with six genes displaying significant differential expression (|log 2FC|≥1, P<0.05), implicating their potential roles in salt stress response. CONCLUSION: This study identified and characterized the AP2/ ERF gene family in R. soongorica at the genomic level, thereby establishing a foundation for elucidating its functional roles in this species’ adaptation to arid and saline environments.
