Although the biological function of fruiting is the production and dissemination of seeds, humans have developed seedless fruits in a number of plant species to facilitate consumption. Here we describe a unique spontaneous seedless mutant (Thai seedless; Ts) of Annona squamosa (sugar apple), a member of the early-divergent magnoliid angiosperm clade. Ovules (seed precursors) of the mutant lack ...

Parthenocarpy, the formation of seedless fruits in the absence of functional fertilisation, is a desirable trait for several important crop plants including tomato (Solanum lycopesicum). Seedless fruits can be of great value for consumers, processing industry and breeding companies. In this paper we propose a novel strategy to obtain parthenocarpic tomatoes, by down-regulation of the flavonoid ...

The exploitation of synthetic polyploids for producing seedless fruits is well known in watermelon. Tetraploid progenitors of triploid watermelon plants, compared with their diploid counterparts, exhibit wide phenotypic differences. Although many factors modulate alternative splicing (AS) in plants, the effects of autopolyploidization on AS are still unknown. In this study, we used tissues of l...

Gibberellins (GAs) regulate numerous developmental processes in grapevine (Vitis vinifera) such as rachis elongation, fruit set, and fruitlet abscission. The ability of GA to promote berry enlargement has led to its indispensable use in the sternospermocarpic ('seedless') table grape industry worldwide. However, apart from VvGAI1 (VvDELLA1), which regulates internode elongation and fruitfulness...

Researchers in New Zealand have cloned and characterized a gene which, when disrupted, allows apples to develop without seeds. This highly prized trait, fully developed in only a handful of other fruits, has proved a big bonus for growers and consumers alike. What's more, in apples the phenotype might offer other potential advantages for growers of this often difficult crop. Thousands of apple ...

YABBY family genes play important roles in the development of leaf, flower, and fruit. The purpose of this research was to integrate all the YABBY genes and analyze the correlation between gene expression and fruit shape in tomato. Scanning of 24 genomes of sequenced species demonstrated that YABBY genes were very normal and stable in flowering plants except the seedless plants. Nine YABBY gene...

The influence of GA3 application on the fruit quality and productivity of cane pruned Thompson seedless was evaluated. Four treatments applied were: GA3, Girdle, GA3 + Girdle and control with no GA3 and no girdle were used. GA3 or GA3 + Girdle berries resulted in heavier berries, hastened berry diameter, and produced larger berries in comparison to the control grapevine trees. In addition, bunc...
