Isolation and characterization of the Chrysanthemum nitrate transporter CmNRT1
In this study, the nitrate transporter gene CmNRT1 was isolated from the chrysanthemum variety ‘Nannongxuefeng’. The full-length cDNA contains an open reading frame of 1761 bp encoding 587 residues. Using qRT-PCR, we found that CmNRT1 was induced by 10 mM NO3- in roots and shoots. Two Arabidopsis thaliana transgenic plants expressing CmNRT1 were selected for functional analyses. Root 15N influx in wild-type and transgenic A. thaliana lines under 10 or 0.2 mM 15NO3 was tested.
Effect of different compounds on the induction of laccase production by Agaricus blazei
Laccases are polyphenol oxidases produced by many fungi and have many applications in textile, food and beverage, and pulp and paper industries. Laccase production can be induced using aromatic or phenolic compounds that mostly affect the transcription of laccase-encoding genes. In this study, we analyzed laccase and biomass production by Agaricus blazei in the presence of different concentrations of nitrogen, copper, and inducers such as pyrogallol, veratryl alcohol, xylidine, vanillin, guaiacol, and ethanol. Laccase production by A.
