Early anther ablation triggers parthenocarpic fruit development in tomato

[EN] Fruit set and fruit development in tomato is largely affected by changes in environmental conditions, therefore autonomous fruit set independent of fertilization is a highly desirable trait in tomato. Here, we report ...
El control hormonal del cuajado del caqui (Diospyros kaki Thunb.)

Cabrera Vicente, Diego (Universitat Politècnica de València, 2018-03-02)

[ES] El cv. Rojo Brillante de caqui (Diospyros kaki Thunb.) sólo produce flores pistiladas y el ovario presenta una alta capacidad partenocárpica. Sin embargo, y tras el cuajado, los frutos sufren una caída fisiológica ...
El desacoplamiento del período de polinización efectiva como método para obtener paltines en el aguacate (Persea americana Mill.)

García Alfonso, Guillem (Universitat Politècnica de València, 2021-01-04)

[ES] La utilización del ácido giberélico (GA3) a una concentración de100 mg l-1 durante el periodo de floración consigue desacoplar el periodo de polinización efectiva del aguacate y, con ello, promover la partenocarpia ...
Engineered Male Sterility by Early Anther Ablation Using the Pea Anther-Specific Promoter PsEND1

Roque Mesa, Edelin Marta; Gómez Mena, María Concepción; Hamza, Rim; BELTRAN PORTER, JOSE PIO; Cañas Clemente, Luís Antonio (Frontiers Media SA, 2019-06-25)

[EN] Genetic engineered male sterility has different applications, ranging from hybrid seed production to bioconfinement of transgenes in genetic modified crops. The impact of this technology is currently patent in a wide ...
Estudio de los mecanismos moleculares de la producción de frutos sin semillas en tomate

López Martín, María Jesús (Universitat Politècnica de València, 2019-04-01)

[ES] El desarrollo del ovario en un fruto (cuajado del fruto) depende de que ocurra la polinización y fertilización del mismo y puede verse comprometido por condiciones ambientales desfavorables. Sin embargo, en algunas ...
First RNA-seq approach to study fruit set and parthenocarpy in zucchini (Cucurbita pepo L.)

Pomares-Viciana, T; Del Rio-Celestino, M; Roman, B; Die, J; Picó Sirvent, María Belén; Gómez, P (Springer (Biomed Central Ltd.), 2019-02-06)

[EN] Background: Zucchini fruit set can be limited due to unfavourable environmental conditions in off-seasons crops that caused ineffective pollination/fertilization. Parthenocarpy, the natural or artificial fruit development ...
Gibberellin reactivates and maintains ovary-wall cell division causing fruit set in parthenocarpic Citrus species

Mesejo Conejos, Carlos; Yuste Gallasch, Roberto; Reig Valor, Carmina; Martínez Fuentes, Amparo; Iglesias, Domingo; Muñoz Fambuena, Natalia; Bermejo del Castillo, Almudena; Germanà, Maria Antonietta; Primo Millo, Eduardo; Agustí Fonfría, Manuel (Elsevier, 2016)

[EN] Citrus is a wide genus in which most of the cultivated species and cultivars are natural parthenocarpic mutants or hybrids (i.e. orange, mandarin, tangerine, grapefruit). The autonomous increase in GA(1) ovary ...
Involvement of ethylene biosynthesis and signalling in fruit set and early fruit development in zucchini squash (Cucurbita pepo L.)

Martinez, C.; Manzano, S.; Megias, Z.; Garrido, D.; Picó Sirvent, María Belén; Jamilena, M. (BioMed Central, 2013-09-22)

Background: We have identified a kind of parthenocarpy in zucchini squash which is associated with an incomplete andromonoecy, i.e. a partial conversion of female into bisexual flowers. Given that andromonoecy in this and ...
Relación entre la síntesis de giberelinas y la activación de la división celular en el ovario de la flor del mandarino 'Clemenules' durante la fase de cuajado

Navarro Consuelo, María (Universitat Politècnica de València, 2018-03-02)

[ES] La partenocarpia se produce cuando un ovario se desarrolla sin la fecundación de sus óvulos y, por tanto, sin sus semillas. Este fenómeno es común en muchas especies y variedades de cítricos. En las variedades sin ...
Silencing C-19-GA 2-oxidases induces parthenocarpic development and inhibits lateral branching in tomato plants

Martínez Bello, Liliam; Moritz, Thomas; Lopez Diaz, Isabel (Oxford University Press (OUP), 2015-09)

GA 2-oxidases regulate gibberellin levels in ovaries and axillary buds of tomato plants and their silencing is responsible for parthenocarpic fruit growth and branching inhibition.Gibberellins (GAs) are phytohormones that ...
Sources of parthenocarpy for Zucchini breeding: relationship with ethylene production and sensitivity

Martinez, C.; Manzano, S.; Megias, Z.; Garrido, D.; Picó Sirvent, María Belén; Jamilena, M. (Springer Verlag (Germany), 2014-12)

Parthenocarpy is becoming an essential trait for off-season greenhouse production of Zucchini squash. Given that winter conditions promote a reduction in the number of male flowers and in the activity of pollinators, the ...
