[EN] Ovule development is essential for plant survival, as it allows correct embryo and seed development upon fertilization. The female gametophyte is formed in the central area of the nucellus during ovule development, ...
Gibberellins modulate light signalling pathways to prevent seedling de-etiolation in darkness.

Alabadí, David; Gallego-Bartolomé, Javier; Orlando, Leonardo; García-Cárcel, Laura; Rubio, Vicente; Martínez, Cristina; Frigerio, Martín; Iglesias-Pedraz, Juan Manuel; Espinosa, Ana; Wang Deng, Xing; BLAZQUEZ RODRIGUEZ, MIGUEL ANGEL (Blackwell Publishing, 2008-01)

[EN] In many plants, photomorphogenesis is the default developmental program after seed germination, and provides the key features that allow adaptation to light. This program is actively repressed if germination occurs ...
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 ...
