MpACL5 Thermospermine synthase (ACAULIS5) Published
Locus assigned by MarpolBase literature-mining curation (2026-10): GenBank LC761627 (MpACL5 mRNA) matches this locus exactly.

Associated Literature (AI-based literature mining)

Central gene of the study, encoding thermospermine synthase; M. polymorpha ACL5 rescues the dwarf acl5 mutant of Arabidopsis. Loss-of-function mutants were generated and analyzed, showing roles in organ development of thalli and reproductive organs, suppression of gametangiophore fasciation, and stress responses. Preferentially expressed in meristematic regions; characterized by mutant phenotyping, expression analysis, and complementation.
