Step by step evolution of Indeterminate Domain (IDD) transcriptional regulators: from algae to angiosperms.

ABSTRACT:

Introduction

The Indeterminate Domain (IDD) proteins are a plant-specific subclass of C2H2 Zinc Finger transcription factors. Some of these transcription factors play roles in diverse aspects of plant metabolism and development, but the function of most of IDD genes is unknown and the molecular evolution of the subfamily has not been explored in detail.

Methods

In this study, we mined available genome sequences of green plants (Viridiplantae) to reconstruct the phylogeny and then described the motifs/expression patterns of IDD genes.

Key results

We identified the complete set of IDD genes of 16 Streptophyta genomes. We found that IDD and its sister clade STOP arose by a duplication at the base of Streptophyta. Once on land, the IDD genes duplicated extensively, giving
