Abstract PttKN1 gene (Populus tremula × P. tremuloides KNOTTED1) was isolated from the vascular cambium of a hybrid aspen. Previous studies on transformed plants with the PttKN1 gene suggested that it plays roles in plant development (typically in meristem initiation), maintenance and organogenesis in simple-leaved species. To investigate the gene functions further, sequence analysis of the deduced amino acid was conducted. The results suggested that the gene belongs to the class I KNOX gene (KNOTTED1-like homeobox genes) family and might play important roles in plant development by coding a transcription factor. The gene was introduced into Cardamine hirsuta using… More >
