Crowell DN, Amasino RM: Induction of Specific mRNAs in Cultured Soybean Cells during Cytokinin or Auxin Starvation. Plant Physiol. 1991 Mar;95(3):711-5.
We report the isolation of five cDNA clones whose corresponding mRNAs accumulate in cultured soybean cells (Glycine max cv Mandarin) during cytokinin or auxin starvation. The levels of three of these mRNAs decrease rapidly after addition of 5 micromolar zeatin to cytokinin-starved cells or after addition of 10 micromolar alpha-naphthaleneacetic acid to auxin-starved cells. These mRNAs also exhibit various patterns of accumulation in the tissues of intact soybean plants. Partial nucleotide sequence analysis demonstrates that one of the cDNAs in the collection, called SAM46, is 46% identical at the amino acid level to the iron superoxide dismutase gene of Escherichia coli. Expression of this cDNA in Escherichia coli cells results in detectable iron superoxide dismutase activity, confirming the identity of the cDNA. |
