  - Autocrine signaling pathways regulated by RAPID ALKALINIZATION FACTORs (RALFs)
    control cell wall integrity during pollen tube germination and growth in Arabidopsis
    (Arabidopsis thaliana). To investigate the role of pollen-specific RALFs in another
    plant species, we combined gene expression data with phylogenetic and biochemical
    studies to identify candidate orthologs in maize (Zea mays). We show that Clade
    IB ZmRALF2/3 mutations, but not Clade III ZmRALF1/5 mutations, cause cell wall
    instability in the sub-apical region of the growing pollen tube. ZmRALF2/3 are
    mainly located in the cell wall and are partially able to complement the pollen
    germination defect of their Arabidopsis orthologs AtRALF4/19. Mutations in ZmRALF2/3
    compromise pectin distribution patterns leading to altered cell wall organization
    and thickness culminating in pollen tube burst. Clade IB, but not Clade III ZmRALFs,
    strongly interact as ligands with the pollen-specific Catharanthus roseus RLK1-like
    (CrRLK1L) receptor kinases Zea mays FERONIA-like (ZmFERL) 4/7/9, LORELEI-like
    glycosylphosphatidylinositol-anchor (LLG) proteins Zea mays LLG 1 and 2 (ZmLLG1/2)
    and Zea mays pollen extension-like (PEX) cell wall proteins ZmPEX2/4. Notably,
    ZmFERL4 outcompetes ZmLLG2 and ZmPEX2 outcompetes ZmFERL4 for ZmRALF2 binding.
    Based on these data, we suggest that Clade IB RALFs act in a dual role as cell
    wall components and extracellular sensors to regulate cell wall integrity and
    thickness during pollen tube growth in maize and probably other plants.@eng
