Cell Wall Composition and Structure Define the Developmental Fate of Embryogenic Microspores in Brassica napus

Camacho-Fernández, Carolina; Seguí-Simarro, Jose M.; Mir Moreno, Ricardo; Boutilier, Kim; Corral-Martínez, Patricia (Frontiers Media SA, 2021-10-06)

[EN] Microspore cultures generate a heterogeneous population of embryogenic structures that can be grouped into highly embryogenic structures [exine-enclosed (EE) and loose bicellular structures (LBS)] and barely embryogenic ...
Changes in xyloglucan endotransglucosylase/hydrolase (XTHs) expression and XET activity during apple fruit infection by Penicillium expansum Link. A

Muñoz Bertomeu, Jesús; Lorences, E.P. (Springer Verlag (Germany), 2014-02)

Although the plant cell wall is an extremely effective physical barrier against attack by pathogens, most phytopathogenic microorganisms produce enzymes that are capable of degrading cell wall polymers such as pectin and ...
Cytopathic effects incited by viroid RNAs and putative underlying mechanisms

Di Serio, Francesco; De Stradis, Angelo; Delgado Villar, Sonia Guadalupe; Flores Pedauye, Ricardo; Navarro, Beatriz (Frontiers Media, 2013-01-07)

[EN] Viroids are infectious agents identified only in plants so far. In contrast to viruses, the genome of viroids is composed of a tiny circular RNA (250-400 nt) not coding for proteins, but containing in its compact ...
Dynamic Changes in Arabinogalactan-Protein, Pectin, Xyloglucan and Xylan Composition o the Cell Wall During Microspore Embryogenesis in Brassica napus

Corral Martínez, Patricia; Driouich, Azeddine; Seguí-Simarro, Jose M. (Frontiers Media SA, 2019-03-28)

[EN] Microspore embryogenesis is a manifestation of plant cell totipotency whereby new cell walls are formed as a consequence of the embryogenic switch. In particular, the callose-rich subintinal layer created immediately ...
Embryogenic competence of microspores is associated to their ability to form a callosic, osmoprotective subintinal layer

Rivas-Sendra, Alba; Corral Martínez, Patricia; Porcel, R.; Camacho-Fernández, Carolina; Calabuig-Serna, Antonio; Seguí-Simarro, Jose M. (Oxford University Press, 2019-02-01)

[EN] Microspore embryogenesis is an experimental morphogenic pathway with important applications in basic research and applied plant breeding, but its genetic, cellular, and molecular bases are poorly understood. We applied ...
Expression of xyloglucan endotransglucosylase/hydrolase (XTH) genes and XET activity in ethylene treated apple and tomato fruits

Muñoz Bertomeu, Jesús; Miedes, Eva; Lorences, E. P. (Elsevier, 2013-09-01)

[EN] Xyloglucan endotransglucosylase/hydrolase (XTHs: EC 2.4.1.207 and/or EC 3.2.1.151), a xyloglucan modifying enzyme, has been proposed to have a role during tomato and apple fruit ripening by loosening the cell wall. ...
Microspore embryogenesis: cell wall dynamics and reprogramming of cell fate

Camacho Fernández, Carolina (Universitat Politècnica de València, 2021-03-08)

[ES] Los dobles haploides son una gran herramienta para la mejora genética de híbridos debido a que se puede alcanzar la homocigosis completa en una sola generación. Entre las técnicas usadas para obtener estas plantas, ...
Sensibilidad al creasing de las nuevas variedades de naranjo Navel. Influencia del patrón y las condiciones ambientales

Navarro Consuelo, María (Universitat Politècnica de València, 2015-10-07)

[ES] El ¿creasing¿ o ¿clareta¿ de los cítricos es un desorden fisiológico caracterizado por la presencia de depresiones en el exocarpo correspondientes con adelgazamientos y/o rupturas del mesocarpo subyacente; las zonas ...
Ultrastructural immunolocalization of arabinogalactan protein, pectin and hemicellulose epitopes through anther development in Brassica napus

Corral Martínez, Patricia; García-Fortea, Edgar; Bernard, Sophie; Driouich, Azeddine; Seguí-Simarro, Jose M. (Oxford University Press, 2016)

[EN] In this work, we performed an extensive and detailed analysis of the changes in cell wall composition during Brassica napus anther development. We used immunogold labeling to study the spatial and temporal patterns ...
