The aim of this study was to investigate the molecular mechanisms underlying drought acclimation in coffee plants by the identification of candidate genes (CGs) using different approaches. The first approach used the data generated during the Brazilian Coffee expressed sequence tag (EST) project to select 13 CGs by an in silico analysis (electronic northern). The second approach was based on screening macroarrays spotted with plasmid DNA (coffee ESTs) with separate hybridizations using leaf cDNA probes from drought-tolerant and susceptible clones of Coffea canephora var. Conilon, grown under different water regimes. This allowed the isolation of seven additional CGs. The third approach used two-dimensional gel electrophoresis to identify proteins displaying differential accumulation in leaves of drought-tolerant and susceptible clones of C. canephora. Six of them were characterized by MALDI-TOF-MS/MS (matrix-assisted laser desorption-time of flight-tandem mass spectrometry) and the corresponding proteins were identified. Finally, additional CGs were selected from the literature, and quantitative real-time polymerase chain reaction (qPCR) was performed to analyse the expression of all identified CGs. Altogether, >40 genes presenting differential gene expression during drought acclimation were identified, some of them showing different expression profiles between drought-tolerant and susceptible clones. Based on the obtained results, it can be concluded that factors involved a complex network of responses probably involving the abscisic signalling pathway and nitric oxide are major molecular determinants that might explain the better efficiency in controlling stomata closure and transpiration displayed by drought-tolerant clones of C. canephora.

A determinação do ponto ideal de colheita que evite perdas qualitativas e quantitativas é fundamental para a sustentabilidade da cafeicultura. Desta forma devido a necessidade de desenvolver métodos que reduzam as perdas quantitativas, este trabalho objetivou desenvolver curvas de crescimento dos frutos de café conilon por modelos de regressão não lineares visando entender o processo, modelo matemático, de acúmulo de matéria seca nos frutos. Os dados utilizados neste trabalho foram obtidos na Fazenda Experimental Bananal do Norte (FEBN), pertencente ao Centro de Pesquisa Desenvolvimento e Inovação Sul (CPDI Sul) do Incaper em Pacotuba, distrito do município de Cachoeiro de Itapemirim... |
