Ultrastructure of the parasitic interface ofPucciniastrum, Thekopsora, Naohidemyces, andCalyptospora (Uredinales, Pucciniastraceae) in the dikaryotic stage
Tóm tắt
The ultrastructure of dikaryotic haustoria of sevenPucciniastrum species,Thekopsora galii, Naohidemyces vaccinii, andCalyptospora goeppertiana was investigated.Pucciniastrum actinidiae, P. agrimoniae, P. pyrolae, andCalyptospora goeppertiana revealed haustoria whose necks were wrapped by a fold of the extrahaustorial matrix. The matrix-fold ofCalyptospora goeppertiana was characteristically shaped.Pucciniastrum circaeae, P. epilobii, P. hikosanense, P. styracinum, Thekopsora galii, andNaohidemyces vaccinii showed typical haustorial necks which were not sheathed by a matrix-fold. Haustorial necks which were wrapped by a fold of the extrahaustorial matrix were designated “velopedunculate,” and those which were naked “gymnopedunculate.” The application of haustorial ultrastructure as a character for use in systematics is discussed.
