Freesia hybrida were used as materials in this study to isolate the 1-aminocyclopropane-1-carboxylate synthase gene FhACS1 (GenBank Accession No.HQ833204) with Genome-Walking method and to investigate the expression characters of this gene in different developmental stages and floret organs, the expression patterns induced by different chemical inducements, drought and cold environment with real-time PCR. The main results are as follows:
1. The new gene, FhACS1, was isolated from Freesia hybrida for the...
