Investigation of the regulation of the CBP20 gene in Arabidopsis

Renáta Bacsó, István Papp

Research output: Contribution to journalArticle


The Arabidopsis mutant line cbp20 carries a lesion in the Cap Binding Protein 20 gene, which is a member of the nuclear cap binding (nCBC) complex. The cbp20 mutant displays elevated sensitivity to abscisic acid (ABA). Apparently this property leads to fast stomatal closure and thus improved drought tolerance. We found that this gene's transcription is elevated by exogenous application of a cytokinin hormone (BAP), suggesting a hormonal control over its expression. These data represent a new aspect of the regulation of the CBP20 gene and the nCBC complex.
