Electronic Theses and Dissertations

Puccinia recondita ultrastructure resembles that of other rust species. The urediospore infection was characterized by the formation of a specialized structure, the haustorium, within the leaf cells. The haustorium contains organelles such as nuclei, mitochondria, microbodies, ribosomes, lipid bodies, and vacuoles. A haustorial neck connects the haustorium with the haustorial mother cell, and contains a neck band made up of darkly stained material. The neck band was located at the last one third of its length toward the haustorium. The haustorial mother cell was situated intercellularly, and closely adhering to the cell wall, but contained few organelles, and the nucleus …
