Expression of new mutant alleles of AS1 and AS2 genes controlling leaf morphogenesis in Arabidopsis thaliana

Expression of new mutant alleles of AS1 and AS2 genes controlling leaf morphogenesis in... We have studied the morphology and vein branching of rosette leaves in Arabidopsis thaliana mutants as and sa, which proved to be alleles of the A.thaliana AS1 and AS2 genes, respectively. We have also analyzed the localization of bioactive auxin, as measured by the expression of the DR5::GUS transgene, as well as the expression patterns of BP, as measured by the expression of the BP::GUS transgene in leaves of the mutants. In mature leaves of the mutants, BP was expressed ectopically. Furthermore, the mutants showed some defects in the localization and concentration of free auxin compared to the wild type. Our results of studying new alleles of AS1 and AS2 support their role in control of class I KNOX genes and auxin transport. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Developmental Biology Springer Journals

Abstract

We have studied the morphology and vein branching of rosette leaves in Arabidopsis thaliana mutants as and sa, which proved to be alleles of the A.thaliana AS1 and AS2 genes, respectively. We have also analyzed the localization of bioactive auxin, as measured by the expression of the DR5::GUS transgene, as well as the expression patterns of BP, as measured by the expression of the BP::GUS transgene in leaves of the mutants. In mature leaves of the mutants, BP was expressed ectopically. Furthermore, the mutants showed some defects in the localization and concentration of free auxin compared to the wild type. Our results of studying new alleles of AS1 and AS2 support their role in control of class I KNOX genes and auxin transport.
