| Abstract:
A number of interesting side effects of the imidazole fungicide imazalil (IMA) can be observed in diverse tissue cultured plant species. Excessive shoot formation in Araceae, inhibition of bushiness in Gerbera, restoration of normal embryo development in Citrus and histogenic instability of Ficus benjamina chimeras will be discussed. Although some of these cases suggest that IMA inhibits GA biosynthesis and ABA metabolism, experiments with Arabidopsis thaliana indicate that IMA is also a strong brassinosteroid biosynthesis inhibitor. | |
