Investigation of mechanisms underlying seedlessness in a Sangiovese somatic variant through comparative genomic and histological analyses.

ABSTRACT:

Background

Both parthenocarpy and stenospermocarpy lead to seedless grapes. Only parthenocarpy, which is rather rare, generates berries with a complete absence of seed tissues. Stenospermocarpy, which is instead more common, produces berries with seed traces because seed development is promoted by embryo formation and then arrested by its abortion. In viticulture, parthenocarpic varieties account for a minority of the production of seedless table grapes, while they are more commonly used for raisins and very rarely for winemaking. Parthenocarpy is the putative cause of seedlessness in Corinto Nero, a bud sport of the seeded winegrape Sangiovese. In our previous studies, embryo sac abnormalities arising from meiotic disorders were accompanied by transcriptional changes in gene funct
