Local endoreduplication of the host is a conserved process during Phytomyxea-host interaction.

ABSTRACT:

Background

Endoreduplication, a modified cell cycle, involves cells duplicating DNA without undergoing mitosis. This phenomenon is frequently observed in plants, algae, and animals. Biotrophic pathogens have been demonstrated to induce endoreduplication in plants to secure more space or nutrients.

Methods

In this study, we investigated the endoreduplication process triggered by two phylogenetically distant Rhizaria organisms-Maullinia spp. (in brown algae) and Plasmodiophora brassicae (in plants)-by combining fluorescent in situ hybridization (FISH) with nuclear area measurements.

Results

We could confirm that Plasmodiophora brassicae (Plasmodiophorida) triggers endoreduplication in infected plants. For the first time, we also demonstrated
