Background: Certain hereditary spastic paraplegia (HSP)-related proteins possess hairpin domains and regulate the morphology of the endoplasmic reticulum (ER) network. Results: Protrudin possesses a… Expand
Sterol analysis of DMI-resistant and -sensitive strains of Venturia inaequalis
- N. Shirane, H. Takenaka, Kazuo Ueda, Y. Hashimoto, K. Katoh, H. Ishii
- Biology
- 1 March 1996
The sterol composition of Venturia inaequalis strains sensitive and resistant to sterol demethylation-inhibiting fungicides (DMI) were analysed. Without DMI treatment, both strains contained… Expand
