Abstract
In several gametophytic self-incompatible species of the Solanaceae, a group of RNases named relic S-RNase has been identified that belong to the S-RNase lineage but are no longer involved in self-incompatibility. However, their function, evolution and presence in the Scrophulariaceae remained largely unknown. Here, we analyzed the expression of S-RNase and its related genes in Antirrhinum, a member of the Scrophulariacaeae, and identified a pistil-specific RNase gene; AhRNase29 encodes a predicted polypeptide of 235 amino acids with an estimated molecular weight of 26 kDa. Sequence and phylogenetic analyses indicated that AhRNase29 forms a monophyletic clade with Antirrhinum S-RNases, similar to that observed for other relic S-RNases. Possible evolution and function of relic S-RNases are discussed.
