Altered expression of the caffeine synthase gene in a naturally caffeine-free mutant of Coffea arabica. Author(s): MALUF, M. P.; SILVA, C. C. da; OLIVEIRA, M. de P. A. de; TAVARES, A. G.; SILVAROLLA, M. B.; GUERREIRO FILHO, O. In this work, we studied the biosynthesis of caffeine by examining the expression of genes involved in this biosynthetic pathway in coffee fruits containing normal or low levels of this substance. The... ... Repository: BDPA Publication year: 2009
Assisted-selection of naturally caffeine-free coffee cultivars-characterization of SNPs from a methyltransferase gene. Author(s): FAVORETTO, P.; SILVA, C. C. da; TAVARES, A. G.; GIATTI, G.; MORAES, P. F.; LOBATO, M. T. V.; SILVAROLLA, M. B.; OLIVEIRO FILHO, G.; MALUF, M. P. Breeding of caffeine-free coffee cultivars require tools for an early selection of progenies bearing this later trait. Genes from caffeine synthesis and degradation represent major targets for the dev... ... Repository: BDPA Publication year: 2017
Sugar metabolism during coffee fruit development. Author(s): GEROMEL, C.; FERREIRA, L. P.; CAVALARI, A. A.; PEREIRA, L. F. P.; VIEIRA, L. G. E.; LEROY, T.; MAZZAFERA, P.; MARRACCINI, P. In this study, we investigated more particularly the sucrose synthase (Susy: EC2.4.1.13) at the biochemical and molecular levels during the development of coffee fruits. In addition, feeding experimen... ... Repository: BDPA Publication year: 2005
Isolation and characterization of endophytic bacteria of coffee plants and their potential in caffeine degradation. Author(s): NUNES, F. V.; MELO, I. S. de The plant kingdom is colonized by a diverse array of endophytic bacteria, which form a non-pathogenic relationship with their hosts. Endophytic bacteria may confer benefits to the plant, and the benef... ... Repository: BDPA Publication year: 2006
Composition of Coffea canephora Varieties from the Western Amazon. Author(s): ACRE, L. B.; VIENCZ, T.; ROCHA, R. B.; ALVES, E. A.; BENASSI, M. T. This research aimed to compare the composition profiles of roasted Coffea canephora varieties (conilon, robusta, and intervarietal hybrids) grown in the Western Amazon. Ten coffees of each variety wer... ... Repository: BDPA Publication year: 2024
Draft genome sequence of Bacillus amyloliquefaciens subsp. plantarum strain S2784, an isolate useful for microbial control. Author(s): ROCHA, G.; GRYNBERG, P.; QUEIROZ, P.; TOGAWA, R. C.; PURCENA, T.; MARTINS, E. Repository: BDPA Publication year: 2022
Methylxanthins and tannins content in young leaves of guaranaze cultivars under different production systems. Author(s): SANTOS, L. P.; SCHIMPL, F. C.; SILVA, E. de B.; SANTOS, G. A. N. dos; SILVA, J. F. da This work was developed with the general objective of evaluating the potential of using young guarana leaves as raw material for the food, cosmetics and pharmaceutical industries, and with specific ob... ...

Biochemical and genomic analysis of sucrose metabolism during coffee (Coffea arabica) fruit development. Author(s): GEROMEL, C.; FERREIRA, L. P.; GUERREIRO, S. M. C.; CAVALARI, A. A.; POT, D.; PEREIRA, L. F. P.; LEROY, T.; VIEIRA, L. G. E.; MAZZAFERA, P.; MARRACCINI, P. Sucrose metabolism and the role of sucrose synthase were investigated in the fruit tissues (pericarp, perisperm, and endosperm) of Coffea arabica during development. Acid invertase, sucrose phosphate... ... Repository: BDPA Publication year: 2006
Teores de trigonelina, cafeína e ácidos clorogênicos em cafés Coffea canephorahíbridos intervarietais naturais cultivados na Amazonia Ocidental. Author(s): FRANCISCO, J. S.; ALMEIDA, I. F. de; PORTELA, C. da S.; ALVES, E. A.; ROCHA, R. B.; MORI, A. L. B.; BENASSI, M. de T. Considerando a limitação de dados na literatura para cafés da espécie C. canephora, oobjetivo do trabalho foi estudar o perfil de compostos bioativos hidrossolúveis (trigonelina, cafeína e ácidos clor... ...
