Term Information

Accession: PO:0001015
Name: K second mitotic division stage
Ontology: plant_structure_development_stage
Synonyms: tricellular pollen development stage (exact), tricellular pollen stage (exact), pollen stage 9 in Arabidopsis (related), stamen stage ST6-4 (related)
Alternate IDs: None
Definition: A pollen development stage (PO:0001007) during which the generative cell (PO:0020097) undergoes mitotic division to form two male gametes, the pollen sperm cells (PO:0025121). Source: POC:Laurel_Cooper, TAIR_curator:Katica_Ilic
Comment: In taxa with mature two-celled pollen (PO:0025281), the second mitotic division takes place after pollen germination (GO:0009846), in the germinating pollen tube cell (PO:0025195). Note: This term overlaps with the GO BP term: generative cell mitosis (GO:0055047): The process in which the generative cell divides by mitosis to form two haploid cells. These will subsequently differentiate into sperm cells.
