Androgenesis in recalcitrant solanaceous crops

Seguí-Simarro, Jose M.; Corral Martínez, Patricia; Parra Vega, Verónica; Gonzalez Garcia, Beatriz (Springer Verlag (Germany), 2011-05)

[EN] Tomato, eggplant, and pepper are three solanaceous crops of outstanding importance worldwide. For hybrid seed production in these species, a fast and cheap method to obtain pure (homozygous) lines is a priority. ...
Aspectos básicos y aplicados de la inducción de embriogénesis en microsporas de pimiento y colza

Parra Vega, Verónica (Universitat Politècnica de València, 2015-03-31)

La embriogénesis derivada de microsporas es la ruta androgénica más empleada para la obtención de individuos dobles haploides (DHs), 100% homocigotos, que pueden ser utilizados como líneas puras. Este proceso es ...
Formation and excretion of autophagic plastids (plastolysomes) in Brassica napus embryogenic microspores

Parra Vega, Verónica; Corral Martínez, Patricia; Rivas-Sendra, Alba; Seguí-Simarro, Jose M. (Frontiers Media, 2015-02)

[EN] The change in developmental fate of microspores reprogrammed toward embryogenesis is a complex but fascinating experimental system where microspores undergo dramatic changes derived from the developmental switch. ...
Induction of embryogenesis in Brassica napus microspores produces a callosic subintinal layer and abnormal cell walls with altered levels of callose and cellulose

Parra Vega, Verónica; Corral Martínez, Patricia; Rivas-Sendra, Alba; Seguí-Simarro, Jose M. (Frontiers Media, 2015-11-25)

The induction of microspore embryogenesis produces dramatic changes in different aspects of the cell physiology and structure. Changes at the cell wall level are among the most intriguing and poorly understood. In this ...
Mitochondrial Zea mays Brittle1-1 Is a Major Determinant of the Metabolic Fate of Incoming Sucrose and Mitochondrial Function in Developing Maize Endosperms

Bahaji, Abdellatif; Muñoz, Francisco José; Seguí-Simarro, Jose M.; Camacho-Fernández, Carolina; Rivas-Sendra, Alba; Parra Vega, Verónica; Ovecka, Miroslav; Li, Jun; Sánchez-López, Ángela María; Almagro, Goizeder; Baroja-Fernández, Edurne; POZUETA-ROMERO, JAVIER (Frontiers Media SA, 2019-03-12)

[EN] Zea mays Brittle1-1 (ZmBT1-1) is an essential component of the starch biosynthetic machinery in maize endosperms, enabling ADPglucose transport from cytosol to amyloplast in exchange for AMP or ADP. Although ZmBT1-1 ...
Morphological markers to correlate bud and anther development with microsporogenesis and microgametogenesis in pepper (Capsicum annuum L.)

Parra Vega, Verónica; Gonzalez Garcia, Beatriz; Seguí Simarro, José María (Springer Verlag (Germany), 2013-02)

The identification of microspores or pollen grains at particular developmental stages during microsporogenesis or microgamentogenesis is an important step for different basic and applied purposes. Among them, the most ...
Novel features of Brassica napus embryogenic microspores revealed by high pressure freezing and freeze substitution: evidence for massive autophagy and excretion-based cytoplasmic cleaning

Corral Martínez, Patricia; Parra Vega, Verónica; Seguí-Simarro, Jose M. (Oxford University Press (OUP): Policy B - Oxford Open Option A, 2013)

[EN] Induction of embryogenesis from isolated microspore cultures is a complex experimental system where microspores undergo dramatic changes in developmental fate. After ~40 years of application of electron microscopy to ...
Reprogramación hacia embriogénesis de microsporas en cultivares dulces de pimiento (Capsicum annuum L.) mediante cultivo in vitro de microsporas aisladas

Parra Vega, Verónica (Universitat Politècnica de València, 2011-07-28)

En este trabajo se ha desarrollado un protocolo inicial para llevar a cabo la inducción de la androgénesis a partir del cultivo de microsporas aisladas de genotipos dulces de pimiento (Capsicum annuum L.). El objetivo ...
Stress treatments and in vitro culture conditions influence microspore embryogenesis and growth of callus from anther walls of sweet pepper (Capsicum annuum L.)

Parra Vega, Verónica; Renau Morata, Begoña; Sifres Cuerda, Alicia Gemma; Seguí Simarro, José María (Springer Verlag (Germany), 2013-03)

Production of doubled haploids (DHs) is a convenient tool to obtain pure lines for breeding purposes. Until now, the easiest and most useful approach to obtain pepper DHs is via anther culture. However, this method has an ...
The use of corms produced under storage at low temperatures as a sourceof explants for the in vitro propagation of saffron reduces contaminationlevels and increases multiplication rates

Renau Morata, Begoña; Moya, L.; González Nebauer, Sergio; Seguí-Simarro, José M.; Parra Vega, Verónica; Gómez Jiménez, Maria Dolores; Molina Romero, Rosa Victoria (Elsevier, 2013)

Saffron is a triploid sterile crop with a low vegetative propagation rate, which prevents the widespread use of selected genotypes. Despite efficient in vitro propagation via direct organogenesis being very interesting, ...
Unravelling massive crocins transport and accumulation through proteome and microscopy tools during the development of saffron stigma

Gómez Gómez, Lourdes; Parra Vega, Verónica; Rivas Sendra, Alba; Seguí Simarro, José María; Molina Romero, Rosa Victoria; Pallotti Sagripanti, Claudia Gabriela; Rubio Moraga, Ángela; Diretto, Gianfranco; Prieto, Alicia; Ahrazem, Oussama (MDPI, 2017-01-01)

Crocins, the glucosides of crocetin, are present at high concentrations in saffron stigmas and accumulate in the vacuole. However, the biogenesis of the saffron chromoplast, the changes during the development of the stigma ...
