Dried product and a drying process

A dried fruit or vegetable has a water content in the range 4% to 7%, and has a water activity of 0.4. Substantially all of the cells of the dried product are undamaged. An air drying process is gentle and contains four phases, during which the temperature of the drying air is maintained at 60° C. In a first phase the relative humidity of the drying air is allowed to rise to between 50% and 55%, and is maintained substantially constant at this value during a second phase by maintaining exchange of the drying air with fresh air substantially constant. In a third phase of the process, the relative humidity of the drying medium is permitted to decrease relatively rapidly until the fourth phase commences, at which stage the relative humidity is permitted to asymptotically approach a predetermined relative humidity value. During the drying process, excessive temperature differences and relative humidity differences between the temperature and relative humidity, respectively of the drying medium and the product are avoided in order to minimize damage to the cellular structure of the product.

P15 hairpin constructs and use

The present invention concerns a method of genetic modification of a TGB-3 wild type viral sequence for reducing or suppressing the possible deleterious effects of the agronomic properties of a transformed plant or plant cell by said TGB-3 viral sequence, comprising the following successive steps: submitting said sequence to point mutation(s) which allow the substitution of at least one amino-acid into a different amino-acid; selecting genetically modified TGB-3 wild type viral sequences having said point mutation(s) and which are not able to promote cell-to-cell movement of a mutant virus having a dysfunctional TGB-3 wild type viral sequence, when expressed in trans from a replicon; further selecting among said genetically modified TGB-3 viral sequences, the specifically genetically modified sequence which inhibits infection with a co-inoculated wild type virus when the mutant form was expressed from a replicon, and recovering said specifically genetically modified TGB-3 viral sequence. The invention further relates to genetically modified TGB-3 viral sequences suitable to induce gene silencing. In particular hairpin constructs based on such sequences proved highly efficient to induce a PTGS mechanism and degradation of the whole of RNA2 thereby. When plants are transformed accordingly the spread of the virus in the plant is significantly reduced or blocked.
