摘要：
We have studied the activity of the chimeric gene DR5::GUS that indicates the spatial pattern of free auxin distribution and relative auxin level in the tissues of A. thaliana plants. It is established that the temperature sensitive abruptus mutation leads to temperature dependent increased accumulation of the free auxin in leaves, staments, and sepals in comparison to control plants homozygous for the wild type allele ABRUPTUS/PINOID. Our data revealed the important role of the ABRUPTUS/PINOID gene in the regulation of the auxin polar transport.
