A core collection of modified strawberry germplasm as a resource tool for funghi infection and fruit texture studies
(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
(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
(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
(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
(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 ... -
Efecto del silenciamiento de genes que codifican poligalacturonasas sobre el reblandecimiento del fruto de fresa asociado a la maduración
(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 ... -
Fruit cell culture as a model system to study cell wall changes during strawberry fruit ripening
(2016-07-01)Strawberry (Fragaria x ananassa, Duch.) fruit is characterized by its fast ripening and soft texture at the ripen stage, resulting in a short postharvest shelf life and high economic losses. It is generally believed that ... -
Nanostructural changes in cell wall pectins during strawberry fruit ripening assessed by atomic force microscopy
(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
(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 ... -
Poligalacturonasa FaPG1 y CRISPR/Cas9: Editando la firmeza del fruto de fresa
(2019-09-30)El uso de la técnica CRISPR/Cas9 para la edición de genomas vegetales ha sido ampliamente estudiado y referido en los últimos años. En trabajos recientes, se ha empleado esta técnica para mejorar la vida postcosecha y ... -
Rhamnogalacturonase lyase gene downregulation in strawberry and its potential on mechanical fruit properties
(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 ... -
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
(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 ...
