Aspterric acid and 6-hydroxymellein, inhibitors of pollen development in Arabidopsis thaliana, produced by Aspergillus terreus.
Aspterric Acid, 6-Hydroxymellein, Arabidopsis thaliana, Aspergillus terreus Aspterric acid (1) and 6-hydroxymellein (2), inhibitors of pollen development in Arabidopsis thaliana, have been isolated from the fungus Aspergillus terreus. 1 and 2 inhibited the pollen development at concentrations of 38 and 52 microM, respectively. The microscopic examination of pollen development suggested that the inhibition by the treatment with 1 caused at meiosis and the inhibition by the treatment with 2 caused at microspore stage. 1 and 2 could be useful agents for the molecular investigation of anther and pollen development in higher plants.
