A proteomic approach to guarana seed and pericarp maturation

Paullinia cupana Kunth var. sorbilis (Mart.) Ducke, the cultivated guarana plant, is native to the Amazon and has been valued for its medicinal, stimulant and energetic properties for centuries. The seeds are the main commercial product of the plant and the source of high amounts of purine alkaloids (caffeine and theobromine) and polyphenols (flavonoids, catechins, .. Read More»

Guarana has great agricultural potential and is largely used therapeutically and in the production of non-alcoholic energy drinks. Genomic and proteomic studies are crucial to identify proteins that play central roles in the maintenance and viability of fruits, as well as to identify proteins related to the main metabolic pathways. However, the success of any protei.. Read More»

    I.B. Cordeiro1, D.P. Castro7, P.P.O. Nogueira7, P.C.S. Angelo6, P.A. Nogueira7, J.F.C. Gonçalves8, A.M.R.F. Pereira9, J.S. Garcia2,3, G.H.M.F. Souza2,4, M.A.Z. Arruda5, M.N. Eberlin2, S. Astolfi-Filho1, E.V. Andrade1 and J.L. López-Lozano10

Chromobacterium violaceum is a Gram-negative proteobacteria found in water and soil; it is widely distributed in tropical and subtropical regions, such as the Amazon rainforest. We examined protein expression changes that occur in C. violaceum at different growth temperatures using electrophoresis and mass spectrometry. The total number of spots detected was 1985; the number ranged from 99 to 3.. Read More»
