Caracterización morfológica de las traqueidas de pino híbrido de rápido crecimiento
(Universidad del Bío-Bío; Chile, 2022-06-15)El objetivo de este trabajo fue evaluar la variación radial de la morfología de las traqueidas de pinos híbri- dos. Se extrajeron tarugos radiales de árboles de pino híbrido “F1 INTA-PINDO”, en dos ensayos. Las muestras ... -
Cell-wall chemical-composition analysis of a Saccharum spp. progeny for increased bagasse digestibility
(International Society of Sugar Cane Technologists, 2019-09)Knowledge of cell-wall composition in sugarcane hybrids could be used for the selection of cultivars with high bagasse digestibility in order to improve sugar release in 2G ethanol production. Cell-wall components of 76 ... -
Changes on the cell wall composition of tree-ripened “Bartlett” pears (Pyrus communis L.)
(Elsevier, 2012-11)Most of the European pear cultivars fail to develop a desirable texture when ripening on the tree. In order to identify some biochemical anomalies that might be associated with this phenomenon, the main differences in cell ... -
Compositional changes in cell wall polysaccharides from five sweet cherry (Prunus avium L.) cultivars during on-tree ripening
(American Chemical Society, 2014-12)Excessive softening is a major cause of postharvest deterioration during transportation and storage of fresh cherries. In continuing our studies to identify the factors determining the textural differences between sweet ... -
La constitución de la pared celular durante la madurez en planta de peras Bartlett, y sus modificaciones por la incidencia de luz : consecuencias sobre la eficacia de los tratamientos con 1-metilciclopropeno
(Facultad de Agronomía, Universidad de Buenos Aires, 2013-03)La firmeza es el atributo más importante en las peras y está determinada en parte, por la estructura de la pared celular (PC) y por su desintegración. No han sido completamente identificadas las modificaciones que ocurren ... -
Developmental changes in cell wall polysaccharides from sweet cherry [Prunus avium L.] cultivars with contrasting firmness
(2013-10)Firmness is a major quality attribute of fresh cherries, and is also a main factor affecting susceptibility to bruising and postharvest rots. In order to identify the factors determining the textural differences between ... -
Expression profile of transcripts encoding cell wall remodelling proteins in tomato fruit cv. Micro-Tom subjected to 15°C storage
(2013)To extend fruit market life, tomatoes are harvested before red ripe and kept at temperatures below optimum (20°C). In this work, Micro-Tom tomatoes stored at 20°C (normal ripening) were compared with those stored at 15°C ... -
Genome-wide data (ChIP-seq) enabled identification of cell wall-related and aquaporin genes as targets of tomato ASR1, a drought stress-responsive transcription factor
(BMC, 2014-01)Background: Identifying the target genes of transcription factors is important for unraveling regulatory networks in all types of organisms. Our interest was precisely to uncover the spectrum of loci regulated by a widespread ... -
Mycobacterial MCE proteins as transporters that control lipid homeostasis of the cell wall
(Elsevier, 2022-01)Mammalian cell entry (mce) genes are not only present in genomes of pathogenic mycobacteria, including Mycobacterium tuberculosis (the causative agent of tuberculosis), but also in saprophytic and opportunistic mycobacterial ... -
