The cruciferous genus Brassicahas a self-incompatibility system that is under the sporophytic control of a single locus, S(ref. 1). Although evidence has accumulated that S-locus-specific proteins, termed S-glycoproteins2–4, are strongly associated with the expression of self-incompatibility4–8, their structures and functions are still unknown. This paper reports the sequences of the S-glycoproteins from three homozygotes of Brassica campestris. They show extensive homology. The published DNA sequence data for the S6-glycoprotein of B. oleracea9can be revised to encode the total sequence of the glycoprotein on the basis of the sequences of S-glycoproteins of B. campestris. These S-glycoproteins have cysteine-rich clusters and 6–7 oligosaccharide chains. There is no homology between the S-glycoproteins of Nicotiana alata10and those of B. campestris. |
