The biosynthesis, degradation, and function of cell wall β-xylosylated xyloglucan mirrors that of arabinoxyloglucan. [PDF]

New Phytol, 2023
Summary Xyloglucan is an abundant polysaccharide in many primary cell walls and in the human diet. Decoration of its α‐xylosyl sidechains with further sugars is critical for plant growth, even though the sugars themselves vary considerably between species. Plants in the Ericales order – prevalent in human diets – exhibit β1,2‐linked xylosyl decorations.

Mitotic aberrations in coffee (Coffea arabica cv. 'Catimor') leaf explants and their derived embryogenic calli

Electronic Journal of Biotechnology, 2000
Dividing cells of leaves used as sources of explants from coffee plants (Coffea arabica cv. 'Catimor') and those of their derived calli were analyzed for mitotic aberrations. The studied tissues were prepared by squashing and stained with carbolfuchsin. A total of 1551 leaf and 4568 callus cells were surveyed. The majority (79 %) of leaf and calli (75 %

Comportamiento de 33 accesiones de café (Coffea sp.) tipo Catimor en San Ramón, Chanchamayo, Perú

Revista de Investigación e Innovación Agropecuaria y de Recursos Naturales
El café se cultiva en el Perú, hace más de 100 años, y desde entonces, se introdujeron diversas variedades comerciales, mayormente de manera informal, aunque este accionar está cambiado en los últimos años, para bien de la caficultura nacional.

Mathematical Modeling of Moisture Diffusivity and Mass Transfer During Drying of Coffea arabica L. var. Catimor

Agriculture
Understanding mass transfer mechanisms during coffee drying is essential for optimizing postharvest processing conditions. This study aimed to estimate the effective moisture diffusivity coefficient (Deff) and convective mass transfer coefficient (hm) of

Transformation of coffee (Coffea Arabica L. cv. Catimor) with the cry1ac gene by biolistic, without the use of markers Transformação do café (Coffea arabica L. cv. Catimor) com o gene cry1ac por bombardeamento, sem usar marcadores

Brazilian Journal of Biology, 2010
The transformation of coffee plantlets with the cry1ac gene of Bacillus thuringiensis was achieved by biolistic using either the whole pUBC plasmid or only the ubi-cry1ac-nos genetic cassette.

Phylogenetic relationship of coffee leaf rust in the central jungle of Peru

Acta Agronómica, 2022
Coffee leaf rust is the main disease that causes significant losses in Coffea arabica. In Peru, this disease caused epidemics between 2008 and 2013 with production losses of 35 %. The objective was to identify H.
