Abstract
|
|
|
|
To better understand the molecular control of floral development, we identified a flower-specific cDNA, RsPCP1, from Korean radish (Raphanus safivus). Based on nucleotide sequence analysis, this clone contains an open reading frame of 65 amino acids and shares 91% identity with a pollen coat protein from cabbage (Brassica oleracea). Southern analysis revealed that RsPCP1 is present as a single-copy gene or a member of a small gene family in the radish genome. Because RsPCP1 mRNA was present exclusively in mature floral buds but not in young floral buds or in vegetative tissues, we propose that this gene is anther-specific.
