The objective of the present work was to study the possibilities of claiming areas planted with low coppicing Eucalyptus spp through the interplanting of seedlings of the same species. Due to the higher initial coppice vigour and growth rate, special care has to be taken in managing the coppice as well the to be interplanted seedling production to make this practice feasible. The inicial trials were carried out in two experimental areas in Mogi-Guacu-SP. The first area was made up of two E.grandis stands from Rio Claro-SP seed (natural hybrid) with low yield in the first rotation (cutting at 10 year age). The second area, a E.grandis stand from Coff's Harbour - Australia seed with high yield in the first rotation (cutting at 8 years age). In both areas, the interplanting was made with seedlings from Coff's Harbour seed in the beginning of the dry season with the application of 200g/planting pit of a 10-20-10 NPK fertilizer respectively 80 and 60 days after cutting for the first and for second areas. The controlled fire practice was used in association with the treatments in order to study its effects on coppice performance. The analysis from the results allowed the following conclusions: (a) the use of the interplanting as a practice aiming the substitution of the dead stumps is feasible in Eucalyptus stands after the first rotation; (b) the controlled fire practice use is initially not advisable in areas to be interplanted; (c) the coppice prunning aiming the phasing of development of the coppice and of the inter MenosThe objective of the present work was to study the possibilities of claiming areas planted with low coppicing Eucalyptus spp through the interplanting of seedlings of the same species.

ABC transporters represent one of the largest superfamilies of active membrane transport proteins (MTPs) with a highly conserved ATPase domain that binds and hydrolyzes ATP, supplying energy for the uptake of a variety of nutrients and for the extrusion of drugs and metabolic wastes. The complete genomes of a non-pathogenic (J) and pathogenic (7448) strain of Mycoplasma hyopneumoniae, as well as of a pathogenic (53) strain of Mycoplasma synoviaehave been recently sequenced. A detailed study revealed a high percentage of CDSs encoding MTPs in M. hyopneumoniaestrains J (13.4%), 7448 (13.8%), and in M. synoviae53 (11.2%), and the ABC systems represented from 85.0 to 88.6% of those CDSs. Uptake systems are mainly involved in cell nutrition and some might be associated with virulence. Exporter systems include both drug and multidrug resistant systems (MDR), which may represent mechanisms of resistance to toxic molecules. No relation was found between the phylogeny of the ATPase domains and the lifestyle or pathogenicity of Mycoplasma, but several proteins, potentially useful as targets for the control of infections, were identified. |
