Characterization of MpGSNOR1 gene reveals its importance in immune function and development of Marchantia polymorpha, suggesting ancestral plant roles.

Key Points

This research aims to understand the role of S-nitrosylation and the MpGSNOR1 gene in immune regulation and development in the liverwort Marchantia polymorpha.
Characterized the MpGSNOR1 gene using loss-of-function alleles
Employed CRISPR/Cas9 genome editing to disrupt MpGSNOR1
Assessed morphological changes resulting from MpGSNOR1 disruption
Examined S-nitrosothiol homeostasis and immune function
Disruption of MpGSNOR1 led to significant morphological alterations
MpGSNOR1 was shown to be essential for maintaining S-nitrosothiol levels
Demonstrated the crucial role of MpGSNOR1 in immune responses of Marchantia
