Summary

This summary is machine-generated.

Transcription-associated proteins (TAPs) evolved significantly in early plant lineages. TAPscan v4 reveals new TAPs crucial for plant terrestrialization and the evolution of land plants.

Area Of Science

  • Plant genomics
  • Evolutionary biology
  • Bioinformatics

Background

  • Transcription-associated proteins (TAPs) are vital for gene regulation and development.
  • TAPs exhibit lineage-specific evolutionary patterns.
  • Genome-wide annotation of TAPs is essential for understanding their roles.

Purpose Of The Study

  • To present TAPscan v4, an updated tool for genome-wide TAP annotation.
  • To analyze the distribution and evolution of TAP families across diverse organisms, focusing on Archaeplastida.
  • To provide the underlying "Genome Zoo" dataset for further research.

Main Methods

  • Utilized domain profiles for comprehensive TAP annotation.
  • Analyzed 138 TAP families across 678 species.
  • Integrated updated web interface and curated protein dataset.

Main Results

  • Identified 18 new TAP (sub)families, with nine originating in Streptophyta or streptophyte algae.
  • Over one-third of TAP family gains occurred in streptophyte algae, predating land plant emergence.
  • The TAP complement of Zygnematophyceae closely resembles that of land plants.

Conclusions

  • TAP evolution in streptophyte algae was critical for plant terrestrialization.
  • The study retraces streptophyte TAP evolution, identifying the regulatory repertoire of early land plants.
  • TAPscan v4 provides a valuable resource for plant genomics and evolutionary studies.
