Journal Article
Genome-wide analysis of the AarPDR gene family in Artemisia argyi and its potential role in regulating terpenoids transport
2025
Overview
Background
The pleiotropic drug resistance (
PDR
) proteins, which are full-sized ABCG transporters belonging to the ATP-binding cassette (ABC) family, play an indispensable role in regulating various physiological and developmental processes of plants. However, the
PDR
transporters and their functional roles in
Artemisia argyi
, a significant traditional medicinal plant in Asia, remain poorly understood.
Results
In this study, a total of 68
PDR
genes, distributed across 17 chromosomes, were identified in the genome of
Artemisia argyi
and classified into five distinct subgroups based on phylogenetic analysis and domain types. The evolutionary characteristics investigation of the
AarPDR
gene family demonstrated that the 9
AarPDR
genes had a high conservation between the genomes of
Artemisia argyi
and Arabidopsis during the evolution of dicots. Cis-element analysis revealed that
AarPDRs
might respond to diverse environmental stresses and multiple plant hormones. Furthermore, the expression analysis in different tissues and developmental stages of leaves indicated that various
AarPDRs
displayed distinct expression profiles within or among subfamilies, and the
AarPDRs
expression could be easily induced by the light conditions. Besides, the
AarPDR
family proteins had a potential function in metabolite transportation.
Conclusions
The
AarPDRs
were characterized by integrating genome analysis, transcriptome, and metabolite profiling. The results can provide useful clues for future studies aimed at the functional characterization of
AarPDR
genes.
