摘要:

目的 生长素响应因子(auxin response factor, ARF)在植物激素信号转导和非生物胁迫应答过程中发挥关键调控作用,对紫苏PfARF转录因子家族进行全基因组鉴定,分析相关基因在非生物胁迫下的表达特性,为阐明PfARF在紫苏逆境应答中的功能提供理论基础。 方法 从紫苏基因组中鉴定PfARF成员,利用TBtools、MEGA11、NCBI-CD Search等组学工具分析其染色体定位、系统进化及保守结构等特征。通过RNA-seq和RT-qPCR分析PfARFs基因在紫苏发育种子和幼苗非生物胁迫下的表达情况。应用分子克隆技术获得PfARF22基因,通过本氏烟草叶片瞬时表达检测其编码蛋白亚细胞定位。构建PfARF22转录因子的蛋白互作网络图,利用分子对接技术对其结合位点、结合能等进行分析。 结果 在紫苏中共鉴定到29个PfARF家族成员,划分为4个亚族,同一亚族PfARF成员的保守基序和基因结构具有相似性,片段重复是其进化和扩增的主要驱动力。PfARF家族成员在紫苏发育种子和幼苗非生物胁迫下差异表达,PfARF22基因在低温和干旱胁迫下显著高表达,亚细胞定位分析表明PfARF22定位于细胞核。分子对接结果表明PfARF22与PfMADS1可能协同调控紫苏生长发育及非生物胁迫应答等过程。 结论 紫苏PfARF转录因子家族共有29个成员,PfARF22在紫苏生长发育和低温及干旱等胁迫应答过程中具有潜在调控作用。

Abstract:

Objective Auxin response factor (ARF) plays a crucial regulatory role in plant hormone signal transduction and abiotic stress responses. The genome-wide identification of the Perilla frutescens PfARF transcription factor (TF) family and the analysis of the expression characteristics of related genes under abiotic stress provide a theoretical basis for elucidating the function of PfARF in the stress response of perilla. Method The PfARF members were identified from the genome of perilla, and their chromosomal location, phylogenetic evolution and conserved structures were analyzed using omic tools, such as TBtools, MEGA11, NCBI-CD Search, et al. The expressions of PfARF genes in the developing seeds of perilla and in the seedlings under abiotic stress was analyzed through RNA-seq and RT-qPCR. The PfARF22 gene was obtained using molecular cloning technology, and the subcellular localization of its encoded protein was detected by transient transformation in Nicotiana benthamiana leaves. A protein interaction network diagram of the PfARF22 TF was constructed, and its binding sites, binding energies, and other parameters were analyzed using molecular docking technology. Result A total of 29 PfARF family members were identified in perilla, which were classified into four subgroups. PfARF members in the same subgroup exhibited similarities in their conserved motifs and gene structures, and segment duplication was the main driving force for their evolution and expansion. PfARF genes showed differential expression in the developing seeds of perilla and in the abiotic stress conditions of the seedlings. The expression of PfARF22 gene significantly increased under low temperature and drought stress conditions. Subcellular localization analysis revealed that PfARF22 was located in nucleus. The molecular docking results indicated that PfARF22 and PfMADS1 cooperatively regulated biological processes such as the growth and development of perilla and responses to abiotic stress. Conclusion Perilla PfARF TF family consists of 29 members. PfARF22 has potential regulatory effects on the growth and development of perilla as well as responses to stress conditions such as low temperature and drought.
