A. thaliana accessions that express developmentally-stable transgenic SI.

aFloral bud 13: Stage-13 of flower development according to [54].bSI: self-incompatible; SC: self-compatible.cNumber of seeds produced per plant over its lifetime by open pollination. The number��SD is based on averaging the number of seed produced by three plants in each group (two plants for Hodja). With the exception of Col-0::AlSRKb-SCRb transformants, which set as much seed as untransformed plants, AlSRKb-SCRb transformants of the other accessions shown produced very low seed set. This low seed set reflects a minor degree of leakiness of the SI trait equivalent to that observed with some naturally self-incompatible A. lyrata genotypes.dSome of these plants were generated by transformation with AlSRKb-SCRb in a pCAMBIA1300 vector and selection on hygromycin.eSimilar results were previously reported for these accessions [26].
