Light represses conidiation in koji mold Aspergillus oryzae.
In the filamentous fungus Aspergillus oryzae, there has been no report on photoreaction. Here we investigated the effect of light in A. oryzae and found that conidiation was repressed by white light. This reaction is contrary to that of other Aspergilli, which show abundant conidiation under light. Moreover, red light also caused reduced conidiation. Genome sequencing of A. oryzae indicated the...
متن کاملRegulation of conidiation by light in Aspergillus nidulans.
Light regulates several aspects of the biology of many organisms, including the balance between asexual and sexual development in some fungi. To understand how light regulates fungal development at the molecular level we have used Aspergillus nidulans as a model. We have performed a genome-wide expression analysis that has allowed us to identify >400 genes upregulated and >100 genes downregulat...
متن کاملRhythmic conidiation in constant light in vivid mutants of Neurospora crassa.
In Neurospora crassa, a circadian rhythm of conidiation (asexual spore formation) can be seen on the surface of agar media. This rhythm has a period of 22 hr in constant darkness (D/D). Under constant illumination (L/L), no rhythm is visible and cultures show constant conidiation. However, here we report that strains with a mutation in the vivid (vvd) gene, previously shown to code for the phot...
متن کاملAnalysis of fluG mutations that affect light-dependent conidiation in Aspergillus nidulans.
Conidiation in Aspergillus nidulans is induced by exposure to red light but can also be induced by blue light in certain mutant strains. We have isolated a mutation in the fluG gene that abolishes responsiveness to red light but does not affect the response to blue light. It has been shown that the veA1 (velvet) mutation allows conidiation to occur in the absence of light. We have identified th...
متن کاملa benchmarking approach to optimal asset allocation for insurers and pension funds
uncertainty in the financial market will be driven by underlying brownian motions, while the assets are assumed to be general stochastic processes adapted to the filtration of the brownian motions. the goal of this study is to calculate the accumulated wealth in order to optimize the expected terminal value using a suitable utility function. this thesis introduced the lim-wong’s benchmark fun...
