Genome-wide identification and expression analysis of the MADS-box gene family during female and male flower development in Juglans mandshurica.

ABSTRACT: The MADS-box gene family plays a crucial role in multiple developmental processes of plants, especially in floral organ specification and the regulation of fruit development and ripening. Juglans mandshurica is a precious fruit material whose quality and yield are determined by floral organ development. The molecular mechanism of J. mandshurica female and male flower development depending on MADS-box genes remains unclear. In our study, 67 JmMADS genes were identified and unevenly distributed on 15 of 16 J. mandshurica chromosomes. These genes were divided into two types [type I (Mα, Mγ, Mδ) and type II (MIKC)]. The gene structure and motif analyses showed that most genes belonging to the same type had similar gene structures and conserved motifs. The analysis o
