The principal aim of this study was to investigate the molecular mechanisms underlying the response to drought stress in coffee plants by different approaches. In order to indentify candidate genes involved in controlling drought tolerance in coffee plants, different strategies were followed in our laboratories. The first used the nucleic data generated by the Brazilian Coffee EST project to identify candidate genes (CG) by in silico analysis (electronic Northern-blot). Differential expression of these CG was verified in leaves and roots from drought-tolerant and susceptible clones of C. canephora var. Conilon by Northern-blot and quantitative PCR experiments. The second was based on the screening of macroarray membranes spotted with coffee ESTs which were hybridized separately with leaf cDNA probes of the same clones. Finally, 2D gel electrophoresis was also performed to selected proteins presenting differential accumulation in leaves of the same clones. These proteins were analyzed by MALDI-TOF-MS/MS leading to the identification of a new set of CG. Results concerning the identification of CG by these different approaches are presented and discussed. |

The economics of coffee plantations is intrinsically linked to pruning, which can improve the canopy architecture and thereby increase productivity. However, recommended pruning times on conilon coffee plantations have been made on an entirely empirical basis. In this study, by evaluating growth, photosynthetic gas exchanges, starch accumulation and crop productivity, the effects of pruning at different times between harvest and flowering were investigated for six conilon coffee clones with distinct stages of fruit maturation (early, intermediate and late). Clones with an early maturation stage were pruned at four different times: 0, 30, 60 and 90 days after harvest (DAH). Intermediate clones were pruned at 0, 30 and 60 DAH, and late clones were pruned at 0 and 30 DAH. Overall, the rates of shoot growth and net photosynthesis, the stomatal conductance and the crop yield were not affected by the pruning treatments in any of the clones. In addition, pruning times did not affect the concentrations of starch or the photochemical efficiency of photosystem II. The carbon isotope composition ratio was marginally affected by the treatments. These results suggest that the pruning time after harvests is relatively unimportant and pruning operations can be scheduled to optimise the use of labour, which directly impacts the production costs of coffee. |
