Suppression effect of CIPC on nucleoli in Vicia faba root tip cells

The effects of CIPC, or isopropyl N-(3-chlorophenyl) carbamate, on nucleolar activity of Vicia faba root tip cells were examined. The nucleoli of CIPC-treated cells were smaller, frequetly had segregated contents, much lower RNA contents, and reduced biosynthesis of RNA by two-thirds. These facts ar...

Zusammenfassung:The effects of CIPC, or isopropyl N-(3-chlorophenyl) carbamate, on nucleolar activity of Vicia faba root tip cells were examined. The nucleoli of CIPC-treated cells were smaller, frequetly had segregated contents, much lower RNA contents, and reduced biosynthesis of RNA by two-thirds. These facts are discussed in conjunction with the hypothesis that the mode of action of CIPC is somehow related to inhibition of gene derepression at the molecular level.
