An integrated analysis of mRNA and sRNA transcriptional profiles in Coffea arabica L. roots: insights on nitrogen starvation responses. Repositório Alice

Coffea arabica L. is an important agricultural commodity, accounting for 60% of traded coffee worldwide. Nitrogen (N) is a macronutrient that is usually limiting to plant yield; however, molecular mechanisms of plant acclimation to N limitation remain largely unknown in tropical woody crops. In this study, we investigated the transcriptome of coffee roots under N starvation, analyzing poly-A+ libraries and small RNAs. We also evaluated the concentration of selected amino acids and N-source preferences in roots. Ammonium was preferentially taken up over nitrate, and asparagine and glutamate were the most abundant amino acids observed in coffee roots.We obtained 34,654 assembled contigs by mRNA sequencing, and validated the transcriptional profile of 12...

Coffea arabica which accounts for 70% of world coffee production is an allotetraploid with a genome size of approximately 1.3 Gb and is derived from the hybridization of C. canephora (710 Mb) and C. eugenioides (670 Mb). To elucidate the evolutionary history of C. arabica, and generate critical information for breeding programs, a sequencing project is underway to finalize a reference genome using a dihaploid line and a set of Menu Abstract: Dihaploid <em>Coffea arabica</Em> Genome Sequencing and Assembly (Plant and Animal Genome XXIII Conference) https://pag.confex.com/pag/xxiii/webprogram/Paper16983.html [25/02/2015 15:00:12] 30 C. arabica accessions.

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...

Towards a better understanding of the Coffea Arabica genome structure. Repositório Alice
MUELLER, L.; STRICKLER, S.; DOMINGUES, D.; PEREIRA, L.; ANDRADE, A.; MARRACCINI, P.; MING, R.; WAI, J.; ALBERT, V.; GIULIANO, G.; FIORE, A.; PIETRELLA, M.; APREA, G.; DESCOMBES, P.; MOINE, D.; GUYOT, R.; PONCET, V.; HAMON, P.; HAMON, S.; TRANCHANT, C.; COUTURON, E.; KOCHKO, A. de; LEPELLEY, M.; BELLANGER, L.; MEROT-L'ANTHOENE, V.; VANDECASTEELE, C.; RIGOREAU, M.; CROUZILLAT, D.; PASCHOAL, A.

An international consortium was initiated in 2012 with the goal to perform the sequencing of the Coffea arabica genome. This consortium includes 34 researchers, engineers and technicians coming from 13 institutions in six different countries. In December 2013 the first draft genome of a Coffea species was published in Science (Denoeud et al. 2014), it is the genome of the C. canephora species, a diploid and the second mainly cultivated species after C. arabica. This later species is the only tetraploid of the genus resulting from a recent spontaneous hybridization (± 0,5 Mya) between C. eugenioides, a wild species from East Africa, and C. canephora, whose genome was sequenced (Lashermes et al. 1999).
