Genome-wide association study reveals candidate genes influencing lipids and diterpenes contents in Coffea arabica L . Repositório Alice
SANT'ANA, G. C.; PEREIRA, L. F. P.; POT, D.; IVAMOTO, S. T.; DOMINGUES, D. S.; FERREIRA, R. V.; PAGIATTO, N. F.; SILVA, B. S. R. da; NOGUEIRA, L. M.; KITZBERGER, C. S. G.; SCHOLZ, M. B. S.; OLIVEIRA, F. F. de; SERA, G. H.; PADILHA, L.; LABOUISSE, J-P.; GUYOT, R.; CHARMETANT, P.; CHARMETANT, P.; LEROY, T..
Lipids, including the diterpenes cafestol and kahweol, are key compounds that contribute to the quality of coffee beverages. We determined total lipid content and cafestol and kahweol concentrations in green beans and genotyped 107 Coffea arabica accessions, including wild genotypes from the historical FAO collection from Ethiopia. A genome-wide association study was performed to identify genomic regions associated with lipid, cafestol and kahweol contents and cafestol/kahweol ratio. Using the diploid Coffea canephora genome as a reference, we identified 6,696 SNPs. Population structure analyses suggested the presence of two to three groups (K = 2 and K = 3) corresponding to the east and west sides of the Great Rift Valley and an additional group formed by...

Diterpenes biochemical profile and transcriptional analysis of cytochrome P450s genes in leaves, roots, flowers, and during Coffea arabica L. fruit development. Repositório Alice
IVOMOTO, S. T.; SAKURAY, L. M.; FERREIRA, L. P.; KITZBERGER, C. S. G.; SCHOLZ, M. B. S.; POT, D.; LEROY, T.; VIEIRA, L. G. E.; DOMINGUES, D. S.; PEREIRA, L. F. P..
Lipids are among the major chemical compounds present in coffee beans, and they affect the flavor and aroma of the coffee beverage. Coffee oil is rich in kaurene diterpene compounds, mainly cafestol (CAF) and kahweol (KAH), which are related to plant defense mechanisms and to nutraceutical and sensorial beverage characteristics. Despite their importance, the final steps of coffee diterpenes biosynthesis remain unknown. To understand the molecular basis of coffee diterpenes biosynthesis, we report the content dynamics of CAF and KAH in several Coffea arabica tissues and the transcriptional analysis of cytochrome P450 genes (P450). We measured CAF and KAH concentrations in leaves, roots, flower buds, flowers and fruit tissues at seven developmental stages...

Analysis of Diterpens in Green and Roasted Coffee of Coffea arabica Cultivars Growing in the Same Edapho-Climatic Conditions. Repositório Alice
KITZBERGER, C. S. G.; SCHOLZ, M. B. S.; PEREIRA, L. F. P.; SERA, T.; SILVA, J. B. G. D.; BENASSI, M. T..
Lipids are important components of coffee beverage flavor and aroma. Coffee oil is rich in diterpens of the kaurane family, mainly cafestol (C20H28O3) and kahweol (C20H26O3), which have increasingly received attention in recent years due to their physiological effects in human health. However, few studies have been conducted on the effects of the genetic variability for those lipids in Coffea arabica. In this work we initiate the characterization of cafestol and kahweol in different cultivars of Coffea arabica, growing in the same edaphoclimatic conditions. Mature coffee fruits from cultivars Catuaí, Icatu and three Catucaí derived the cultivars IPR 100, IPR 102 and IPR 106. They were harvested at the Agricultural Field Station of the Coop COCARI,...

Soluble sugars, enzymatic activities and gene expression during development of coffee fruits submitted to shade condition. Repositório Alice
MARRACCINI, P.; GEROMEL, C.; FERREIRA, L. P.; PEREIRA, L. F. P.; LEROY, T.; POT, D.; DAVRIEUX, F.; RIBEYRE, F.; GUYOT, B.; SCHOLZ, M. B. S.; ANDROCIOLI FILHO, A.; VIEIRA, L. G. E.; MAZZAFERA, P..
Effects of shade (50% light) condition on development and sugar metabolism was analyzed in fruits of Coffea arabica L. var. IAPAR 59. Fresh weight measurements of separated tissues (pericarp, perisperm and endosperm) showed that the increased size observed in beans of shaded plants was correlated with high perisperm development. Reducing sugar contents in the pericarp and endosperm of fruits from shaded plants appeared higher than in the same tissues of control (?full-sun?) plants. On the contrary, sucrose content was slightly lower in shade than in control beans. At the enzymatic level, sucrose synthase activities detected in the latest stages (197-231 DAF) of perisperm development from shaded plants were higher than from of control, confirming the...
