PSI Atlas is a comprehensive knowledgebase of plant self-incompatibility (SI). As an intraspecific outcrossing mechanism, SI widely adopted by hermaphroditic plants is usually controlled by a polymorphic multi-allelic S locus. Typically, six molecular types of SI have been found, including Type-1 controlled by the pistil S S-RNase and pollen S SLFs commonly spread in Plantaginaceae, Solanaceae, Rosaceae and Rutaceae, Type-2 by SRK and SCR in Brassicaceae, Type-3 by PrsS and PrpS in Papaveraceae, Type-4 by CYP-GLO2-KFB-CCM-PUM in Primulaceae, Type-5 by TsSPH1-TsYUC6-TsBAHD in Passifloraceae and Type-6 by HPS10-S and DUF247I-S in Poaceae, with Type-1 characterized as a non-self recognition system but types 2-6 self ones[ref1, 2]. Recently, we classified the self-incompatibility of Linaceae as Type-7 (two distyly candidate genes LtTSS1 and LtWDR-44 are only present in the dominant S allele) and classified the self-incompatibility of Oleaceae as Type-8 (the presence/absence polymorphism of the GA2ox-S gene is stably associated with SI groups across Oleaceae). Here, we collected and reanalyzed the genome resources of those species. Based on the known molecular types of SI, the S-locus information of assembled SI species will been fully explored in the PSI Atlas.
