Genome-wide identification of the MADS-box gene family in Avena sativa and its role in photoperiod-insensitive oat.

ABSTRACT:

Background

Traditional spring-summer sown oat is a typical long-day crop that cannot head under short-day conditions. The creation of photoperiod-insensitive oats overcomes this limitation. MADS-box genes are a class of transcription factors involved in plant flowering signal transduction regulation. Previous transcriptome studies have shown that MADS-box genes may be related to the oat photoperiod.

Methods

Putative MADS-box genes were identified in the whole genome of oat. Bioinformatics methods were used to analyze their classification, conserved motifs, gene structure, evolution, chromosome localization, collinearity and cis-elements. Ten representative genes were further screened via qRT‒PCR analysis under short days.

Results

In total, sixteen AsM
