| MpRALF1 | cysteine-rich peptide RALF1 | Published |
Mecchia et al. 2022 (Development, doi:10.1242/dev.200580) assigns MpRALF3 to this locus and MpRALF1 to Mp1g27120 - the reverse of the genome-paper (Bowman et al. 2017, Table S60) numbering used here. Link by gene ID.
Associated Literature (AI-based literature mining)
Sperm-derived RAPID ALKALINIZATION FACTOR peptide, the central subject of this study. Identified in a screen of the top 1,000 antheridia-expressed genes, MpRALF1 is specifically and highly expressed in mature antheridia (RT-qPCR, proMpRALF1:GUS) and the peptide accumulates in spermatozoid flagella. Three CRISPR/Cas9 frameshift knockout lines and amiRNA knockdown (Ri-MpRALF1) reduced male fertility (fewer sporophytes after crossing), lowered sperm ROS levels and impaired sperm kinematics (reduced curvilinear velocity, fewer rapidly progressive and more slow/non-progressive spermatozoids); 10 nM synthetic MpRALF1 peptide rescued both ROS and motility. MpRALF1 is perceived by the MpFER-MpLLG receptor complex (pulldown, CoIP, luciferase complementation), and its N-terminal 18-aa region binds MpFER whereas its C-terminal 38-aa region binds MpLLG. NAMING NOTE: gene ID stated in the paper, and it matches the original registration (Bowman et al. 2017 Table S60: MpRALF1 = Mapoly0076s0067). Mecchia et al. 2022 (Development, doi:10.1242/dev.200580) is the outlier: it calls this locus MpRALF3 and uses MpRALF1 for Mp1g27120.

· Development research sequence comparator
One of the three M. polymorpha RALF peptide genes analysed as candidate MpFER ligands; clusters with the AtRALF1 subgroup and carries the RRXL motif for S1P processing. NAMING NOTE: this paper's MpRALF numbering is swapped relative to the original naming. Bowman et al. 2017 (Cell 171:287-304) Table S60 registers MpRALF1 = Mapoly0076s0067 (Mp7g07270), MpRALF2 = Mapoly0040s0047 (Mp2g21670) and MpRALF3 = Mapoly0002s0166 (Mp1g27120); MarpolBase and Zhang et al. 2026 (Nat. Plants) follow that original naming. This locus (Mp7g07270) is therefore MpRALF1; the paper calls it MpRALF3. Linked by the ID stated in the paper, not by name.
