Abstract

Synaptonemal complexes (SCs) in nuclei of transitional Plasmodia of Plasmodiophora diplantherae were counted through serial section analysis. On this basis the haploid chromosome number was nine, the lowest haploid number known for Plasmodiophoromycetes. Total length (TL) of SCs per nucleus (approx. 39 μm) was similar to that of P. brassicae (n = 20, TL = approx. 47 μm, vol. = approx. 15 μm³), but nuclear volume (approx. 28 μm³) was similar to those of Polymyxa betae (n = 30, TL = approx. 73 μm, vol. = approx. 26 μm³), P. graminis (n = 30, TL = approx. 70 μm, vol. = approx. 24 μm³), and Sorosphaera veronicae (n = 33, TL = approx. 76 μm, vol. = approx. 25 μ³).
