Genome-Wide Identification and Expression Analysis of Kinesin Family in Barley ().

Kinesin, as a member of the molecular motor protein superfamily, plays an essential function in various plants' developmental processes. Especially at the early stages of plant growth, including influences on plants' growth rate, yield, and quality. In this study, we did a genome-wide identification and expression profile analysis of the kinesin family in barley. Forty-two HvKINs were identified and screened from the barley genome, and a generated phylogenetic tree was used to compare the evolutionary relationships between Rice and Arabidopsis. The protein structure prediction, physicochemical properties, and bioinformatics of the HvKINs were also dissected. Our results reveal the important regulatory roles of genes in barley growth. We found many elements related to and in homeopathic elements of the gene and verified them by QRT-PCR, indicating their potential role in the barley kinesin family. The current study revealed the biological functions of barley kinesin genes in barley and will aid in further investigating the kinesin in other plant species.
