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 ... -
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). ... -
Efecto del silenciamiento de genes que codifican poligalacturonasas sobre el reblandecimiento del fruto de fresa asociado a la maduración
Paniagua Correas, Candelas; García-Gago, Juan Antonio; Matas-Arroyo, Antonio Javier; Barceló-Muñoz, Marta; Blanco-Portales, Rosario; Muñoz-Blanco, Juan; Pliego-Alfaro, Fernando; Quesada-Felice, Miguel Angel; Mercado, Jose A.[et al.] (2015-10-06)
La degradación de las pectinas de la pared celular mediada por poligalacturonasas juega un papel clave en el reblandecimiento de la fresa. Así, el silenciamiento del gen FaPG1 incrementa la firmeza del fruto maduro y alarga ... -
Nanostructural changes in cell wall pectins during strawberry fruit ripening assessed by atomic force microscopy
Paniagua Correas, Candelas; Kirby, Andrew R.; Gunning, A. Patrick; Morris, Victor J.; Matas-Arroyo, Antonio Javier; Quesada-Felice, Miguel Angel; Mercado, Jose A.[et al.] (2015-06-26)
Rapid loss of firmness occurs during strawberry (Fragaria × ananassa Duch) ripening, resulting in a short shelf life and high economic losses. The disassembly of cell walls is considered the main responsible for fruit ... -
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 ... -
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 ... -
Strawberry fruit softening and pectin disassembly: I. Nanostructural characterization of fruit pectins by atomic force microscopy II. Role of the β-Galactosidase gene FaβGal4
(Universidad de Málaga, Servicio de Publicaciones y Divulgación Científica, 2014)La fresa se caracteriza por sufrir un rápido reblandecimiento durante el periodo de maduración, llegando a adquirir una textura semilíquida al final del desarrollo. Esta disminución de firmeza limita el periodo postcosecha ... -
Unravelling the nanostructure of strawberry fruit pectins by atomic force microscopy
Paniagua Correas, Candelas; Kirby, Andrew R.; Gunning, A. Patrick; Morris, Victor J.; Matas-Arroyo, Antonio Javier; Quesada-Felice, Miguel Angel; Mercado, Jose A.[et al.] (2016-07-01)
Atomic force microscopy (AFM) allows the analysis of individual polymers at nanostructural level with a minimal sample preparation. This technique has been used to analyse the pectin disassembly process during the ripening ...
