Aspergillus nidulans conidiation genes dewA, fluG, and stuA are differentially regulated in early vegetative growth.

چکیده
Microarray analysis was used to identify transcriptional changes in early vegetative growth of the filamentous fungus Aspergillus nidulans. The results suggest that the previously identified conidiation genes dewA, fluG, and stuA may function in isotropic expansion during early vegetative growth and asexual reproduction.

NsdD is a key repressor of asexual development in Aspergillus nidulans.
Asexual development (conidiation) of the filamentous fungus Aspergillus nidulans occurs via balanced activities of multiple positive and negative regulators. For instance, FluG (+) and SfgA (-) govern upstream regulation of the developmental switch, and BrlA (+) and VosA (-) control the progression and completion of conidiation. To identify negative regulators of conidiation downstream of FluG-...
متن کاملSuppressor mutations bypass the requirement of fluG for asexual sporulation and sterigmatocystin production in Aspergillus nidulans.
Asexual sporulation (conidiation) in the filamentous fungus Aspergillus nidulans requires the early developmental activator fluG. Loss of fluG results in the blockage of both conidiation and production of the mycotoxin sterigmatocystin (ST). To investigate molecular mechanisms of fluG-dependent developmental activation, 40 suppressors of fluG (SFGs) that conidiate without fluG have been isolate...
متن کاملFluG-dependent asexual development in Aspergillus nidulans occurs via derepression.
The asexual spore is one of the most crucial factors contributing to the fecundity and fitness of filamentous fungi. Although the developmental activator FluG was shown to be necessary for activation of asexual sporulation (conidiation) and production of the carcinogenic mycotoxin sterigmatocystin (ST) in the model filamentous fungus Aspergillus nidulans, the molecular mechanisms underlying the...
متن کاملThe putative guanine nucleotide exchange factor RicA mediates upstream signaling for growth and development in Aspergillus.
Heterotrimeric G proteins (G proteins) govern growth, development, and secondary metabolism in various fungi. Here, we characterized ricA, which encodes a putative GDP/GTP exchange factor for G proteins in the model fungus Aspergillus nidulans and the opportunistic human pathogen Aspergillus fumigatus. In both species, ricA mRNA accumulates during vegetative growth and early developmental phase...
متن کاملThe Aspergillus nidulans fluG gene is required for production of an extracellular developmental signal and is related to prokaryotic glutamine synthetase I.
Mutations in the Aspergillus nidulans fluG gene disrupt the programmed induction of asexual sporulation and result in formation of fluffy colonies that are characterized by undifferentiated cotton-like masses of vegetative cells. We show that the fluG mutant phenotype is suppressed when fluG mutant colonies are grown next to wild-type colonies even if the two strains are separated by dialysis m...
