Genome-wide identification, classification and expression profiling of nicotianamine synthase (NAS) gene family in maize.

ABSTRACT:

Background

Nicotianamine (NA), a ubiquitous molecule in plants, is an important metal ion chelator and the main precursor for phytosiderophores biosynthesis. Considerable progress has been achieved in cloning and characterizing the functions of nicotianamine synthase (NAS) in plants including barley, Arabidopsis and rice. Maize is not only an important cereal crop, but also a model plant for genetics and evolutionary study. The genome sequencing of maize was completed, and many gene families were identified. Although three NAS genes have been characterized in maize, there is still no systematic identification of maize NAS family by genomic mining.

Results

In this study, nine NAS genes in maize were identified and their expression patterns in different organs including develo
