Bioinformatics Identification of Soybean FCS-like Zinc Finger Gene Family
The FCS-like Zinc Finger(FLZ)represents one of the plant-specific gene family,which plays an important regulatory role in plant growth and development and response to adversity stress.However,less is known about the characteristics and functions of FLZ genes in Glycine max.In this study,a total of 40 FLZ(GmFLZs)genes were identified from the G.max genome using the Hmmsearch method,and the protein physicochemical properties,gene structure,promoter cis-acting elements,evolution and gene expression characteristics of GmFLZs were analyzed.The results showed that the average number of amino acids of GmFLZ proteins was 220.7,all of which were hydrophilic proteins.Phylogenetic analysis reveals that GmFLZs can be divided into 7 clusters.There are abundant cis-acting elements related to light signal,hormone and stress response in the promoter sequence of GmFLZs.The GmFLZs are distributed on 20 chromosomes of G.max,and the tandem duplication is not identified,while 28 GmFLZs are involved in segmental duplications.Collinearity analysis showed that 15 GmFLZs were homologous to the FLZ genes in Vigna radiata and Arabidopsis thaliana.Ka/Ks analysis results show that the GmFLZs have experienced different evolutionary directions during the evolution process.The results of protein docking simulation show that GmFLZ7 and GmFLZ9 can dock with the SnRK1α subunit.The results of this study serve as a reference for elucidating the functions of FLZ family genes in G.max.
