Genome-wide identification, molecular docking and expression analysis of enzymes involved in the primary and secondary metabolic branching points of the selenium metabolic pathway in Cardamine hupingshanensis.

ABSTRACT:

Background

Cardamine hupingshanensis is a plant known for its unique selenium tolerance, making it a key model for selenium metabolism research. Adenosine phosphosulfate kinase (APK) and adenosine phosphosulfate reductase (APR) are widely distributed in plants and play a crucial role in selenium metabolism. While genome-wide analyses of the APK and APR families have been conducted across various plant species, a systematic identification and analysis of these gene families in Cardamine hupingshanensis is still lacking.

Results

There are 7 ChAPK and 5 ChAPR genes identified from the genome of C. hupingshanensis, which can be classified into 4 subfamilies for ChAPK and 3 subfamilies for ChAPR, respectively. All these members share similar conserved motifs and gene structures.
