Comprehensive analysis of the INDETERMINATE DOMAIN (IDD) gene family in Marchantia polymorpha brings new insight into evolutionary developmental biology.

ABSTRACT:

Background

SHORTROOT (SHR) and SCARECROW (SCR) are key regulators of plant cell fate. An increasing number of studies have illustrated that the SHR-SCR pathway depends on some INDETERMINATE DOMAIN (IDD) family transcription factors in regulating genes involved in tissue and organ morphogenesis, nutrients transport and metabolism, photoperiodic flowering and stress response. Recent genome sequencing and analysis revealed that only seven IDDs exist in the liverwort Marchantia polymorpha, one of the early diverging extant land plant lineages. However, little is known concerning how the IDDs and the SHR/SCR-IDD pathway work in the ancestral land plants.

Results

In this study, IDD gene family members of this liverwort and other classic model plants were classified into seven bran
