Posé-Albacete, Sara
; Paniagua Correas, Candelas; Matas, Antonio J.; Gunning, A. Patrick; Morris, Victor J.; Quesada-Felice, Miguel Ángel; Mercado, Jose A[et al.] (Elsevier, 2018-02-13)
Este artículo revisa las principales características del proceso de desensamblaje de la pared celular asociado al reblandecimiento de los frutos desde un punto de vista nanoestructural, según lo proporcionado por estudios ... -
AFM study of strawberry pectin nanostructure and its relevance on fruit texture
Pose-Albacete, Sara; Santiago-Doménech, Nieves; Matas-Arroyo, Antonio Javier; Kirby, Andrew R.; Gunning, A. Patrick; Morris, Victor J.; Quesada-Felice, Miguel Ángel; Mercado-Carmona, José Ángel; 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 ... -
Fruit softening and pectin disassembly: an overview of nanostructural pectin modifications assessed by atomic force microscopy,
Paniagua, Candelas; Posé-Albacete, Sara; Morris, Victor J.; Kirby, Andrew R.; Quesada-Felice, Miguel Ángel; Mercado-Carmona, José Ángel[et al.] (Oxford Academy, 2014-07-25)
En esta revisión, se discuten primero las características principales del proceso del desmantelamiento de las pectinas durante la maduración de los frutos, y luego se revisa la caracterización nanoestructural de las pectinas ... -
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 Ángel; Mercado-Carmona, José Ángel[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 R.; Mercado-Carmona, José Ángel; Morris, Victor J.; Quesada-Felice, Miguel Ángel[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 ... -
Structural changes in cell wall pectins during strawberry fruit development
Santiago-Doménech, Nieves; Kirby, Andrew R.; Gunning, A. Patrick; Morris, Victor J.; Paniagua Correas, Candelas; Quesada-Felice, Miguel Ángel; Matas-Arroyo, Antonio Javier; Mercado-Carmona, José Ángel[et al.] (2017)
Strawberry is one of the most important soft fruit. Rapid loss of firmness occurs during the ripening process, resulting in a short shelf life and high economic losses. To get insight into the role of pectin matrix in the ... -
The nanostructural characterization of strawberry pectins in pectate lyase or polygalacturonase silenced fruits elucidates their role in softening
Posé-Albacete, Sara; Kirby, Andrew R.; Paniagua, Candelas; Waldron, Keith W.; Morris, Victor J.; Quesada-Felice, Miguel Ángel; Mercado-Carmona, José Ángel[et al.] (Elsevier, 2015-06-14)
Este estudio investigó el papel de las pectinas en el reblandecimiento de la fresa, mediante plantas transgénicas con silenciamiento de los genes FaplC (liasa de pectato) y FaPG1 (poligalacturonasa). Los frutos transgénicos ... -
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 Ángel; Mercado-Carmona, José Ángel[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 ... -
Unravelling the nanostructure of strawberry fruit pectins by endo-polygalacturonase digestion and atomic force microscopy.
Paniagua Correas, Candelas; Kirby, Andrew R.; Gunning, A. Patrick; Morris, Victor J.; Matas-Arroyo, Antonio Javier; Quesada-Felice, Miguel Ángel; Mercado-Carmona, José Ángel[et al.] (Elsevier, 2016-12-19)
Este estudio analizó las pectinas de las fresas utilizando microscopía de fuerza atómica (AFM) para visualizar sus cadenas y agregados. Las pectinas se trataron con una enzima específica, lo que resultó en una reducción ...
