A core collection of modified strawberry germplasm as a resource tool for funghi infection and fruit texture studies
Pineda, Hugo; Posé, Sara; Paniagua, Candelas; García-Gago, Juan Antonio; Pliego-Alfaro, Fernando; [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, Sara; Santiago-Doménech, Nieves; Matas-Arroyo, Antonio Javier; Kirby, AR; Gunning, A. Patrick; [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, Candelas; Posé, Sara; [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, Candelas; García-Gago, Juan Antonio; Matas-Arroyo, Antonio Javier; Barceló-Muñoz, Marta; Blanco-Portales, Rosario; [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, Candelas; Kirby, Andrew R.; Gunning, A. Patrick; Morris, Victor J.; Matas-Arroyo, Antonio Javier; [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, Sara; Paniagua, Candelas; Kirby, Andrew; Mercado, Jose A; Morris, Victor J.; [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 ... -
Unravelling the nanostructure of strawberry fruit pectins by atomic force microscopy
Paniagua, Candelas; Kirby, Andrew R.; Gunning, A. Patrick; Morris, Victor J.; Matas-Arroyo, Antonio Javier; [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 ...
