Characterization and functional analysis of conserved non-coding sequences among poaceae: insights into gene regulation and phenotypic variation in maize.

ABSTRACT:

Background

Conserved non-coding sequences (CNS) are islands of non-coding sequences conserved across species and play an important role in regulating the spatiotemporal expression of genes. Identification of CNS provides valuable information about potentially functional genomic elements, regulatory regions, and helps to gain insights into the genetic basis of crop agronomic traits.

Results

Here, we comprehensively analyze CNS in maize, by comparing the genomes of maize inbred line B73 (Zea mays ssp. mays), its close wild relative Zea mays spp. mexicana, and other grasses in Poaceae, including sorghum (Sorghum bicolor), foxtail millet (Setaria italica) and two adlay (Coix lacryma) cultivars. There were 289,931 CNS found in two syntenic gene pairs, while 51,701 CNS were conser
