Genome-wide characterization and expression profiling of FARL ( FHY3/FAR1 ) family genes in Zea mays

A significant role of the plant is played by the transcription factor FARL, which is light signal transduction as well as plant growth and development. Despite being transposases, FARL has developed a variety of dominant biological actions in evolution and speciation. On the other hand, little is known about the Zea mays FARL protein family. This study identifies and characterizes fifteen ZmFARL genes genome-wide, and RNA sequencing data was used to profile their expression. 105 FARL proteins from five plant species were classified into five groups based on sequence alignment and phylogeny. The ZmFARL genes' exon-intron and motif distribution were conserved based on their evolutionary group. The fifteen ZmFARL genes were distributed over seven of the ten Z. mays chromosomes, although no duplication was discovered. Cis-element analysis reveals that ZmFARL genes play a variety of activities, including tissue-specific, stress- and hormone-responsive expressions. Furthermore, the results of the RNA sequencing used to profile expression showed that the genes ZmFARL2 and ZmFARL5 were much more expressed than other genes in various tissues, particularly in leaf characteristics. The identification of likely genes involved in cellular activity in Z. mays and related species will be aided by the characterization of the FARL genes.
