Genome-wide identification of the phosphofructokinase gene family in maize (Zea mays L.) and their expression levels under abiotic stress and phytohormones.

ABSTRACT:

Background

Phosphofructokinase (PFK) is the primary rate-limiting enzyme and regulatory site of the glycolysis process, which is crucial for plant growth and the regulation of stress response. The PFK genes in Arabidopsis (Arabidopsis thaliana), wheat (Triticum aestivum), rice (Oryza sativa), cotton (Gossypium spp.) and potato (Solanum tuberosum) have been comprehensively analyzed. However, the PFK genes in maize (Zea mays L.) have not been systematically studied.

Results

In this study, we performed a comprehensive bioinformatic analysis of the maize genome and identified 18 ZmPFK genes. Phylogenetic analysis indicated that these genes are divided into 5 subfamilies. The evolutionary patterns and divergence levels indicate that ZmPFK genes were present before the divergence
