Disease relevance of Coffea

• Green and roasted coffees of the two most used species, Coffea arabica and Coffea robusta, several commercial coffee samples, and known coffee components were analyzed for their ability to interfere with Streptococcus mutans' sucrose-independent adsorption to saliva-coated hydroxyapatite (HA) beads [1].

High impact information on Coffea

• Abscisic acid controls embryo growth potential and endosperm cap weakening during coffee (Coffea arabica cv. Rubi) seed germination [2].
• Isolation of a new dual-functional caffeine synthase gene encoding an enzyme for the conversion of 7-methylxanthine to caffeine from coffee (Coffea arabica L.) [3].
• Changes to the galactose/mannose ratio in galactomannans during coffee bean ( Coffea arabica L.) development: implications for in vivo modification of galactomannan synthesis [4].
• 5-(Hydroxymethyl)-2-furfural (HMF), a pyrolysate of carbohydrate isolated from instant coffee (Coffea arabica L.), selectively inhibits the activities of mammalian DNA polymerase lambda (pol lambda) and terminal deoxynucleotidyltransferase (TdT) which are family X pols, in vitro [5].
• Construction and characterization of a Coffea canephora BAC library to study the organization of sucrose biosynthesis genes [6].

Biological context of Coffea

• 5-Fluoro-alpha-D-galactopyranosyl fluoride was synthesized and its interaction with the active site of an alpha-galactosidase from green coffee bean (Coffea arabica), a retaining glycosidase, characterized kinetically and structurally [7].
• A. rhizogenes strain A4 harbouring plasmid pCAMBIA 1301 with an intron uidA reporter and hygromycin phosphotransferase (hptII) marker gene was used for sonication-assisted transformation of Coffea canephora [8].

Associations of Coffea with chemical compounds

• The first committed step reaction of caffeine biosynthesis: 7-methylxanthosine synthase is closely homologous to caffeine synthases in coffee (Coffea arabica L.) [9].
• Purification and characterisation of adenosine nucleosidase from Coffea arabica young leaves [10].
• Development of ochratoxin A during robusta (Coffea canephora) coffee cherry drying [11].
• The degree and nature of polysaccharide degradation at different roasting levels was determined for three Arabica (Coffea arabica) bean varieties [12].
• Xanthine degradation and related enzyme activities in leaves and fruits of two coffea species differing in caffeine catabolism [13].

Gene context of Coffea

• Addition of a toxic concentration of aluminum (Al) to cell suspension cultures of Coffea arabica L. induced the rapid and transient activation of a protein kinase that phosphorylates myelin basic protein (MBP), as revealed by in-gel kinase assays [14].
• Exposure to toxic concentrations of aluminum activates a MAPK-like protein in cell suspension cultures of Coffea arabica [14].
• Identification and mapping of a major gene (Ft1) involved in fructification time in the interspecific cross Coffea pseudozanguebariae x C. liberica var. Dewevrei: impact on caffeine content and seed weight [15].
• Polyphenol oxidase (PPO) was characterized in partially purified extracts of leaves (PPO-L) and fruit endosperm (PPO-E) of coffee (Coffea arabica L.). PPO activity was higher in early developmental stages of both leaves and endosperm of fruits [16].
• Two independent procedures for the quantitative determination of the polysaccharide content of Arabica Caturra (Coffea arabica var. Caturra) and Robusta ROM (Coffea canephora var. ROM) green coffee beans showed that they both contained identical amounts of polysaccharide [17].

Analytical, diagnostic and therapeutic context of Coffea

• Characterization and estimation of proanthocyanidins and other phenolics in coffee pulp (Coffea arabica) by thiolysis-high-performance liquid chromatography [18].
