Seedless Fruit Production in 'Tosa Buntan' Pummelo

Seedless Fruit Production by Hormonal Regulation of Fruit Set

Seed and fruit development are intimately related processes controlled by internal signals and environmental cues. The absence of seeds is usually appreciated by consumers and producers because it increases fruit quality and fruit shelf-life. One method to produce seedless fruit is to develop plants able to produce fruits independently from pollination and fertilization of the ovules. The onset...

Less is better: new approaches for seedless fruit production.

Pummelo fruit transcript homologous to ripening-induced genes.

Organic acid accumulation in the vacuole of juice cells of citrus fruits is a developmentally regulated process, the degree and timing of which varies greatly among species and varieties and is highly susceptible to environmental conditions (Clements, 1963; Ting and Vines, 1966; Vandercook, 1977). Total titratable acidity of the fruit juice of the acidless pummelo 2240 (Citrus maxima [Burm.] Me...

Influence of Gamma Irradiation on Seedless Citrus Production: Pollen Germination and Fruit Quality

Seedlessness is a desirable characteristic in citrus fruits sold for fresh consumption. Gamma irradiation is widely used to obtain seedless citrus fruits. Here, different clones of the self-incompatible parthenocarpic “Moncada” mandarin, obtained by gamma irradiation, were studied to assess seedlessness, pollen germination, fruit characteristics and quality attributes. Findings indicate that ir...

Overexpression of a gene encoding a cytochrome P450, CYP78A9, induces large and seedless fruit in arabidopsis.

An activation tagging screen in which the cauliflower mosaic virus 35S enhancer was inserted randomly into an Arabidopsis genome homozygous for the floral homeotic mutation apetala2-1 (ap2-1) resulted in a line (28-5) with extraordinarily wide, heart-shaped ovaries. The ovary of the 28-5 ap2-1 mutant shows an oval shape because of increased numbers of enlarged cells. When the ap2-1 mutation is ...
