Apical dominance in saffron and the involvement of the branching enzymes CCD7 and CCD8 in the control of bud sprouting

Rubio Moraga, Angela; Ahrazem, Oussama; Pérez Clemente, Rosa María; Gomez Cadenas, Aurelio; Yoneyama, Koichi; López Ráez, Juan Antonio; Molina Romero, Rosa Victoria; Gómez Gómez, Lourdes (BioMed Central, 2014-06-19)

[EN] Background: In saffron (Crocus sativus), new corms develop at the base of every shoot developed from the maternal corm, a globular underground storage stem. Since the degree of bud sprouts influences the number ...
Auxin drives tomato spotted wilt virus (TSWV) resistance through epigenetic regulation of auxin response factor ARF8 expression in tomato

Werghi, Sirine; APARICIO HERRERO, FREDERIC; Fakhfakh, Hatem; Gorsane, Faten (Elsevier, 2021-12-15)

[EN] Tomato spotted wilt virus (TSWV) causes severe losses of tomato crops worldwide. To cope dynamically with such a threat, plants deploy strategies acting at the molecular and the epigenetic levels. We found that tomato ...
beta-Lactam Antibiotics Modify Root Architecture and Indole Glucosinolate Metabolism in Arabidopsis thaliana

Gudiño, M.; Blanco-Touriñán, Noel; Arbona, V.; Gómez-Cadenas, Aurelio; Blazquez Rodriguez, Miguel Angel; Navarro-García, F. (Oxford University Press, 2018-10)

[EN] The presence of antibiotics in soils could be due to natural production by soil microorganisms or to the effect of anthropogenic activities. However, the impact of these compounds on plant physiology has not been ...
Caracterización fenotípica de mutantes de Arabidopsis thaliana en los genes de las prolil isomerasas ROF1 y ROF2

Fresquet Corrales, Sandra (Universitat Politècnica de València, 2011-09-06)

En trabajos previos en levadura se ha demostrado que la sobreexpresión de FPR1, una inmunofilina de tipo FKBP (FK506 binding proteins), confiere tolerancia a los ácidos orgánicos débiles, como el ácido acético y el sórbico. ...
Della protein function during differential growth processes in arabidopsis

Gallego Bartolomé, Javier (Universitat Politècnica de València, 2011-08-01)

The plant hormones gibberellins (GAs) regulate multiple processes of plant development. Most of this regulation occurs at the transcriptional level, through the activity of the DELLAs, which are nuclear-localized proteins ...
Differential growth at the apical hook: all roads lead to auxin

Abbas, Mohamad; Alabadí Diego, David; Blazquez Rodriguez, Miguel Angel (Frontiers Media, 2013-11-05)

[EN] The apical hook is a developmentally regulated structure that appears in dicotyledonous seedlings when seeds germinate buried in the soil. It protects the shoot apical meristem and cotyledons from damage while the ...
Estudio de la implicación de las auxinas en la formación de los óvulos de tomate y su posible interacción con otras hormonas

Villanueva Párraga, Gloria (Universitat Politècnica de València, 2016-09-05)

[ES] En nuestro laboratorio hemos iniciado el estudio del papel de la hormona giberelina (GA) en la formación de los óvulos de tomate. Mediante el análisis de mutantes, con alteraciones en los niveles hormonales o en su ...
FRUITFULL controls SAUR10 expression and regulates Arabidopsis growth and architecture

Bemer, M.; van Mourik, H.; Muiño, Jose M.; Ferrandiz Maestre, Cristina; Kaufmann, K.; Angenent, G.C. (Oxford University Press, 2017)

[EN] MADS-domain transcription factors are well known for their roles in plant development and regulate sets of downstream genes that have been uncovered by high-throughput analyses. A considerable number of these targets ...
Gibberellins negatively modulate ovule number in plants

Gómez Jiménez, Maria Dolores; Barro-Trastoy, Daniela; Escoms, E.; Saura-Sanchez, M.; Sanchez, I.; Briones-Moreno, Asier; Vera Sirera, Francisco José; Carrera Bergua, Esther; Ripoll, J.J.; Yanofsky, Martin; Lopez Diaz, Isabel; Alonso, J.M.; Perez Amador, Miguel Angel (The Company of Biologists, 2018-07)

[EN] Ovule formation is a complex developmental process in plants, with a strong impact on the production of seeds. Ovule primordia initiation is controlled by a gene network, including components of the signaling pathways ...
Hierarchy of hormone action controlling apical hook development in Arabidopsis

Gallego Bartolomé, Javier; Arana, María Verónica; Vandenbussche, Filip; Zadnikova, P.; Minguet, E.G.; Guardiola Herraez, Vicente Gerardo; Van der Straeten, Dominique; Benková, Eva; Alabadí Diego, David; Blazquez Rodriguez, Miguel Angel (Wiley, 2011-08)

[EN] The apical hook develops in the upper part of the hypocotyl when seeds buried in the soil germinate, and serves to protect cotyledons and the shoot apical meristem from possible damage caused by pushing through the ...
Hormonal control of parthenocarpic fruit set in Rojo Brillante persimmon (Diospyros kaki Thunb.)

Reig Valor, Carmina; Martinez Fuentes, Amparo; Mesejo Conejos, Carlos; Agustí Fonfría, Manuel (Springer-Verlag, 2018)

[EN] In persimmon (Diospyros kaki Thunb.), one to three waves of fruit abscission can occur. The parthenocarpic cv. Rojo Brillante may abscise close to 50% of flowers, which implies a major economic losses. In order to ...
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 ...
Involvement of nitric oxide (NO) and auxin in signal transduction of copper induced morphological responses in Arabidopsis seedlings

Petó, Andrea; Lehotai, Nóra; Lozano Juste, Jorge; Leon Ramos, Jose; Tari, Irma; Erdei, László; Kolbert, Zsuzsanna (Oxford University Press (OUP): Policy B - Oxford Open Option A, 2011-05-19)
