The parthenocarpic gene Pat-k is generated by a natural mutation of SlAGL6 affecting fruit development in tomato ( Solanum lycopersicum L.)
2018
Background
Parthenocarpy is a desired trait in tomato because it can overcome problems with fruit setting under unfavorable environmental conditions. A parthenocarpic tomato cultivar, ‘MPK-1’, with a parthenocarpic gene, Pat-k, exhibits stable parthenocarpy that produces few seeds. Because ‘MPK-1’ produces few seeds, seedlings are propagated inefficiently via cuttings. It was reported that Pat-k is located on chromosome 1. However, the gene had not been isolated and the relationship between the parthenocarpy and low seed set in ‘MPK-1’ remained unclear. In this study, we isolated Pat-k to clarify the relationship between parthenocarpy and low seed set in ‘MPK-1’.
