An RNA-dependent RNA polymerase gene in Arabidopsis is required for posttranscriptional gene silencing mediated by a transgene but not by a virus. One of these, SDE1, is a plant homolog of QDE-1 in Neurospora crassa that encodes an RNA-dependent RNA polymerase. The sde1 mutation was specific...

摘要: Achlya bisexualis has multiple forms of DNA-dependent RNA-polymerase similar to those of other eukaryotes. Cycloheximide acts as a specific inhibitor of DEAE-fraction I enzyme at low concentrations with 50% inhibition at 0.47 μM cycloheximide....
This process of asexual reproduction is distinct from simple mitosis as a means of increasing cell numbers. The possibility of the occurrence of sexual reproduction in P. lunula is discussed. 展开 关键词: plant physiology, plant biochemistry ...
The cAMP-PKA pathway regulates growth, sexual and asexual differentiation, and pathogenesis in Fusarium graminearum. Like many other filamentous ascomycetes, Fusarium graminearum contains two genes named CPK1 and CPK2 that encode the catalytic subunits of cyclic AMP (cAMP... S Hu,X Zhou,X Gu,.....
The Fgvps39 mutant generated by targeted deletion was significantly reduced in vegetative growth and asexual development. It failed to produce sexual spores and was defective in plant infection and deoxynivalenol production. Further cellular localization and cytological examinations suggested that FgVps39 ...
