Transcriptome-wide profiling and expression analysis of transcription factor families in a liverwort, Marchantia polymorpha.

ABSTRACT:

Background

Transcription factors (TFs) are vital elements that regulate transcription and the spatio-temporal expression of genes, thereby ensuring the accurate development and functioning of an organism. The identification of TF-encoding genes in a liverwort, Marchantia polymorpha, offers insights into TF organization in the members of the most basal lineages of land plants (embryophytes). Therefore, a comparison of Marchantia TF genes with other land plants (monocots, dicots, bryophytes) and algae (chlorophytes, rhodophytes) provides the most comprehensive view of the rates of expansion or contraction of TF genes in plant evolution.

Results

In this study, we report the identification of TF-encoding transcripts in M. polymorpha for the first time, as evidenced by deep RNA s
