The self-incompatibility related alleles of the quince genotypes.
Fig 3.
Polypeptide sequence comparison of the five conserved regions of self-incompatibility S1 to S5 alleles in the quince.
The conserved motifs of the S alleles were highlighted. The ‘*’ means same sequence in all alleles; the ‘.’ means amino acid difference in all sequences; and the ‘:’ means more abundance of that amino acid.

Fig 6.
Pollen tube growth after 120 h in two different genotypes of quince: Ardabil2 as a self-compatible (left) and Behta as a self-incompatible (right). a1, b1: one-third at the beginning, a2, b2: one-third in the middle, and a3, b3: one-third at the end. The yellow arrow in a3 indicates the pollen tube.
