A core collection of modified strawberry germplasm as a resource tool for funghi infection and fruit texture studies
Pineda, Hugo; Pose-Albacete, Sara
; Paniagua Correas, Candelas; García-Gago, Juan Antonio; Pliego-Alfaro, Fernando; Quesada-Felice, Miguel Angel; Mercado, José Ángel; Matas-Arroyo, Antonio Javier[et al.] (2013-09-24)
Strawberry has been extensively used as a model organism for functional genomics of genes related with fungi infection (Amil-Ruiz et al, 2011) and fruit ripening, specially fruit texture (Posé et al, 2011). These studies ... -
AFM study of strawberry pectin nanostructure and its relevance on fruit texture
Pose-Albacete, Sara; Santiago-Doménech, Nieves; Matas-Arroyo, Antonio Javier; Kirby, AR; Gunning, A. Patrick; Morris, Victor J; Quesada-Felice, Miguel Angel; Mercado, Jose A.; Paniagua Correas, Candelas[et al.] (2018-10-17)
Atomic force microscopy (AFM) has been used to characterize the nanostructure of cell wall pectins during strawberry fruit growth and ripening, as well as in transgenic fruits with pectinase genes downregulated. This ... -
Cell wall disassembly is delayed by rhamnogalacturonate lyase gene silencing: potential role in fruit firmness
Pose-Albacete, Sara; Ric-Varas, P.; Schückel, J.; Molina-Hidalgo, F.J.; Blanco-Portales, Rosario; Muñoz-Blanco, J.; Knox, P.; Matas-Arroyo, Antonio Javier; Quesada-Felice, Miguel Angel; Mercado, J.A.[et al.] (2019-07-23)
Strawberry fruits greatly reduce their quality due to softening during ripening with economically important losses. Texture changes of fleshy fruits during ripening are mainly due to middle lamellae dissolution, cell-to-cell ... -
Down-regulation of a pectin acetylesterase gene modifies strawberry fruit cell wall pectin stracture and increases fruit firmness
Matas-Arroyo, Antonio Javier; Rodríquez, Virginia; Sánchez, Luis; Paniagua Correas, Candelas; Pose-Albacete, Sara; García-Gago, Juan Antonio; Blanco-Portales, Rosario; Muñoz-Blanco, Juan; Mercado, José A.[et al.] (2015-06-29)
Antisense-mediated down-regulation of several fruit-specific genes has previously demonstrated how the cell wall disassembly in strawberry fruit is mediated by a series of enzymes that act sequentially (Posé et al. 2011). ... -
Downregulation of NAC transcription factors modifies cell wall composition and increases strawberry fruit firmness
Ric-Varas, Pablo; Pose-Albacete, Sara; López-Casado, Gloria; Marcus, S.E.; Knox, P.; Blanco-Portales, Rosario; Moyano, E.; Muñoz-Blanco, J.; Matas-Arroyo, Antonio Javier; Mercado, J.A.[et al.] (2019-07-23)
The strawberry is a soft fruit with a very short post-harvest shelf life. The changes in texture during fruit ripening are mainly due to the dissolution of the middle lamellae, reducing cell-to-cell adhesion, and the ... -
High-throughput mapping of cell wall glycans to unveil cell wall disassembly, a key process determining strawberry fruit softening
Ric-Varas, Pablo; López-Casado, Gloria; Schukel, Julia; Knox, J. Paul; Muñoz-Blanco, Juan; Matas-Arroyo, Antonio Javier; Mercado-Carmona, Jose Angel; Pose-Albacete, Sara[et al.] (ISHS, 2021-05-03)
The short shelf life of strawberry fruit is a major limitation that produces important economic losses related to postharvest spoiling. Fruit texture of fleshy fruits is a complex trait but mainly rely on mechanical ... -
Isolation and transfection of strawverry protoplasts for gene editing
Sánchez-Raya, Cristina; López-Casado, Gloria; Blanco-Portales, Rosario; Pose-Albacete, Sara; Matas, Antonio J.; Mercado, José A.[et al.] (2021)
Strawberry is the most economically important soft fruit. The improvement of the organoleptic qualities of ripe fruit and the postharvest shelf life are main objectives of strawberry breeding programs. Fruit softening is ... -
Nanostructural differences in pectic polymers isolated from strawberry fruits with low expression levels of pectate lyase or polygalacturonase genes
Pose-Albacete, Sara; Paniagua Correas, Candelas; Kirby, Andrew; Mercado, Jose A; Morris, Victor J.; Quesada-Felice, Miguel Angel[et al.] (2013)
Our research group has obtained transgenic strawberry plants expressing antisense sequences of either a pectate lyase (APEL lines) [1] or a polygalacturonase gene (APG lines) [2]. Both genes encode ripening-specific ... -
Optimización de la transfección de protoplastos para la edición génica en fresa
Sánchez-Raya, Cristina; López-Casado, Gloria; Blanco-Portales, Rosario; Pose-Albacete, Sara; Pliego-Alfaro, Fernando; Matas, Antonio J.; Mercado, José A.; Pliego-Alfaro, Fernando[et al.] (2021)
La fresa es un fruto blando de gran importancia económica, particularmente en Andalucía. La mejora de las cualidades organolépticas del fruto y la disminución del reblandecimiento para alargar la vida postcosecha del fruto, ... -
Polygalacturonase gene FaPG1 downregulation is related to increased strawberry fruit resistance to fungal decay
Paniagua Correas, Candelas; Sánchez Raya, C. C; Blanco-Portales, Rosario; Mercado-Carmona, Jose Angel; Palomo-Ríos, Elena; Pose-Albacete, Sara[et al.] (2022-06-16)
Plant health is a major target in breading programs because crops are under constant biotic stress, and climate change is exacerbating pests and disease negative impacts in agriculture. Obtaining crop varieties armed with ... -
Rhamnogalacturonase lyase gene downregulation in strawberry and its potential on mechanical fruit properties
Ric-Varas, Pablo; Pose-Albacete, Sara; Barceló-Muñoz, Marta; Knox, Paul; Blanco-Portales, Rosario; Muñoz-Blanco, Juan; Matas-Arroyo, Antonio Javier; Quesada-Felice, Miguel Angel; Mercado, José A.[et al.] (2017-07-04)
Strawberry softening is one of the main factors that reduces fruit quality and leads to economically important losses. Textural changes during fruit ripening are mainly due to the dissolution of middle lamellae, a reduction ...
