Overview

Research demonstrates GSNOR1's involvement in immune function and development in Marchantia polymorpha, suggesting evolution from ancestral land plants.

Key Points

  • Disruption of GSNOR1 in Marchantia polymorpha led to significant morphological changes and impaired immune responses.
  • Loss-of-function alleles showed that MpGSNOR1 is crucial for maintaining S-nitrosothiol homeostasis in plants.
  • CRISPR/Cas9 genome editing was employed to explore the roles of MpGSNOR1 in immunity and structural development.
  • These findings indicate that S-nitrosylation mechanisms originated in early land plants, influencing both growth and immune responses.
