Abstract

The phytohormone auxin is crucial for plant growth and development. Transportation and distribution of auxin throughout the plant is very important to maintain the auxin homeostasis. Auxin efflux carrier genes play significant roles in auxin transport. In this study, we identified 12 auxin efflux carrier genes from the Setaria italica genome, which are similar in number with that of monocotyledonous plant Oryza sativa. Twelve (12) SiPIN genes are distributed in eight scaffolds. All the identified genes possess the transmembrane auxin efflux carrier domain. Phylogenetic analysis shows that SiPIN genes are much closer to Sorghum bicolor and O. sativa PIN genes of the grass family.

 

Key words: Auxin efflux carrier, auxin efflux carrier domain, phosphorylation, transmembrane domain.
