Comparative analysis of plant MKK gene family reveals novel expansion mechanism of the members and sheds new light on functional conservation.

ABSTRACT:

Background

Mitogen-activated protein kinase (MAPK) cascades play critical functions in almost every aspect of plant growth and development, which regulates many physiological and biochemical processes. As a middle nodal point of the MAPK cascades, although evolutionary analysis of MKK from individual plant families had some reports, their evolutionary history in entire plants is still not clear.

Results

To better understand the evolution and function of plant MKKs, we performed systematical molecular evolutionary analysis of the MAPKK gene family and also surveyed their gene organizations, sequence features and expression patterns in different subfamilies. Phylogenetic analysis showed that plant MAPKK fall into five different groups (Group A-E). Majority orthology groups see
