An investigation of carotenoid biosynthesis in Coffea canephora and Coffea arabica

Journal of Plant Physiology, 2008
Carotenoids are essential components of the photosynthetic apparatus in a wide range of organisms. They participate in the adaptation of plastids to changing environmental light conditions and prevent photo-oxidative damage of the photosynthetic apparatus by detoxifying reactive oxygen species. We identified eight cDNAs from the carotenoid biosynthetic

Inoculation of yeast and bacterium in wet-processed Coffea canephora

Food Chemistry, 2023
This study evaluated the inoculation of Meyerozyma guilliermondii and Bacillus licheniformis, separately or in co-culture, in wet-processed conilon coffee. Wet fermentation was conducted for 48 h. Mesophilic bacteria, lactic acid bacteria, yeasts, and filamentous fungi were counted during fermentation. The inoculation of B.

Auxin Immunolocalization in Coffea canephora Tissues

2018
Auxins are plant growth regulators that participate in a variety of biological mechanisms during the growth and development of plants. The most abundant natural auxin is indole-3-acetic acid (IAA). The physiological processes regulated by IAA depend on their temporal space accumulation in different tissues of a plant.

Resistance to root-lesion nematodes on Coffea canephora

2004
Root-lesion nematodes (Pratylenchus spp.) are widely distributed in coffee plantations worldwide. In Central America, many of them are highly pathogenic on Coffea arabica causing important economic damage. The poor efficiency of nematicide treatments to control Pratylenchus spp. was demonstrated in Guatemala. In this country, C. canephora was used as a

Genetic transformation of Coffea canephora by vacuum infiltration

Plant Cell, Tissue and Organ Culture, 2006
Agrobacterium-mediated plant transformation protocol was evaluated as a fast method to obtain genetically modified Coffea canephora plantlets. Leaf explants were used as source material for Agrobacterium tumefaciens-mediated transformation involving a vacuum infiltration protocol, followed by a step of somatic embryogenesis induction and a final ...

The terroir of Brazilian Coffea canephora: Characterization of the chemical composition

Food Research International
FTIR spectroscopy and multivariate analysis were used in the chemical study of the terroirs of Coffea canephora. Conilon coffees from Espírito Santo and Amazon robusta from Matas of Rondônia, were separated by PCA, with lipids and caffeine being the markers responsible for the separation.

Quantification of Coffea arabica and Coffea canephora var. robusta in roasted and ground coffee blends

Talanta, 2013
This study reports direct quantification of arabica in roasted and ground coffee blends of Coffea arabica and Coffea canephora var. robusta. (1)H-NMR analysis of water extracts of coffee blends were combined with multivariate statistical analysis to obtain an OPLS model with high predictive capability.

Direct somatic embryogenesis in Coffea canephora.

Methods in molecular biology (Clifton, N.J.), 2006
Somatic embryogenesis (SE) provides a useful model to study embryo development in plants. In contrast to zygotic embryogenesis, SE can easily be observed, the culture conditions can be controlled, and large quantities of embryos can be easily obtained. In Coffea spp several model systems have been reported for in vitro SE induction.

AFLP and SSR polymorphism in a Coffea interspecific backcross progeny ((Coffea heterocalyx X Coffea Canephora) X C. Canephora) [S10-45]

2003
An interspecific cross (BC 1) involving a species with one of the biggest genomes in Coffea genus (C. heterocalyx (HET), qDNA = 1.74 pg) and a species with a medium genome size (C. canephora (CAN), qDNA = 1.43 pg) was studied using two types of molecular markers, AFLPTM and SSR.
