A survey of the gene in wild and cultivated potato.

Inbred-hybrid breeding of diploid potatoes necessitates breeding lines that are self-compatible. One way of incorporating self-compatibility into incompatible cultivated potato () germplasm is to introduce the inhibitor gene (), which functions as a dominant inhibitor of gametophytic self-incompatibility. To learn more about diversity and function in wild species relatives of cultivated potato, we obtained gene sequences that extended from the 5'UTR to the 3'UTR from 133 individuals from 22 wild species relatives of potato and eight diverse cultivated potato clones.

and CRISPR-Cas9 double knockouts show enhanced self-fertility in diploid .

The Gametophytic Self-Incompatibility (GSI) system in diploid potato ( L.) poses a substantial barrier in diploid potato breeding by hindering the generation of inbred lines. One solution is gene editing to generate self-compatible diploid potatoes which will allow for the generation of elite inbred lines with fixed favorable alleles and heterotic potential.

The Effect of Self-Compatibility Factors on Interspecific Compatibility in Section .

The relationships of interspecific compatibility and incompatibility in section are complex. Inquiry into these relationships in tomato and its wild relatives has elucidated the pleiotropic and redundant function of and which tandemly and independently mediate both interspecific and intraspecific pollen rejection. Our findings presented here are consistent with previous work conducted in section showing that plays a central role in interspecific pollen rejection.
