Dark dependence of meiosis at elevated temperatures in the basidiomycete Coprinus lagopus.
Under continuous-light regimen Coprinus lagopus can enter and complete meiosis at 25 C, but is unable to do so at 35 C. The temperature-sensitive and the dark-dependent period is 10 hr before karyogamy. It is conjectured that the basidia are programmed for the initiation of meiosis during that 10-hr period.
متن کاملLife history and developmental processes in the basidiomycete Coprinus cinereus.
Coprinus cinereus has two main types of mycelia, the asexual monokaryon and the sexual dikaryon, formed by fusion of compatible monokaryons. Syngamy (plasmogamy) and karyogamy are spatially and temporally separated, which is typical for basidiomycetous fungi. This property of the dikaryon enables an easy exchange of nuclear partners in further dikaryotic-monokaryotic and dikaryotic-dikaryotic m...
متن کاملPositioning the Golgi Apparatus
Ríos et al. (2004) report in this issue that the Golgi protein GMAP-210 is sufficient to confer pericentrosomal positioning and recruits gamma-tubulin and associated microtubule-nucleating ring complex proteins to Golgi membranes. The results raise the possibility that short microtubules emanate from the Golgi to mediate its organization and positioning.
متن کاملThe Golgi apparatus
At some point in their lives all cells need to grow and divide. In eukaryotic cells these processes require the delivery of new proteins and lipids from their site of synthesis in the endoplasmic reticulum (ER) to the cell surface. The Golgi apparatus, first visualised under the light microscope in 1898 by Camillo Golgi using a staining method he had developed to study neurons, lies on the rout...
متن کاملFragmentation of the Golgi Apparatus
Phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2) synthesis has been implicated in maintaining the function of the Golgi apparatus. Here we demonstrate that the inhibition of PtdIns(4,5)P2 synthesis in vitro in response to primary alcohol treatment and the kinetics of Golgi fragmentation in vivo were very rapid and tightly coupled. Preloading Golgi membranes with short chain phosphatidic ac...
