Working model of Heterodera glycines female seam cell division post-infection. Based on observations at multiple time points, we propose that H. glycines J2 seam cells divide following infection to produce two daughter seam cells, which then undergo additional divisions to produce four epidermal nuclei and one seam cell. Subsequent molts result in an increased number of divisions and resulting epidermal nuclei. The number of epidermal nuclei produced by each seam cell was estimated based on the total number of epidermal nuclei found after each molt; however, due to the obligate endoparasitic lifestyle of H. glycines, we are unable to confirm the precise lineage of individual cells
