Contenido :  Eucalyptus dunnii Maiden produces good quality cellulose pulp, showing good frost tolerance. However, in Uru-guay, it needs more than six years to reach the reproductive stage. Genome duplication was proposed as a strategy to obtain useful variability. The application of mitosis inhibitors for chromosomal duplication, in explants growing in vitro, was evaluated. Two antimitotic agents were used: colchicine and oryzalin in different concen-trations and exposure times, in two types of explants: explants growing in vitro and pre-germinated seeds. The number of chloroplasts was used as a rapid ploidy estimator and confirmed by flow cytometry. For chloroplast count, fluorescein diacetate (FDA) applied to in vitro leaves was used for staining. Oryzalin was effective for inducing plant duplication in E. dunnii from in vitro explants. In pre-germinated seeds, both antimitotic agents induced polyploids. The average number of chloroplasts was 5.5 in diploid control plants and more than 7 in tetraploids. Obtained plantlets were successfully cloned in the greenhouse. This is the first report on artificial polyploidy obtained in E. dunnii.

Contenido :  Forestry genetics and genomics require a great number of samples to produce accurate results. This is a simple method with high-throughput DNA extraction that combined CTAB protocol with fast rupture tissue and centrifuge steps in plates to obtain good yield, quality and low price. Approximately 576 samples can be processed for day. The obtained DNA is suitable for use in PCR-based study like Microsatellites. This method employs 96 Racked Collection Microtubes (Qiagen). Eucalyptus tissue 15mg was placed in each well together with a tungsten bead and 420ul of CTAB2X buffer distributed with a multichannel pipette, the samples were disrupted to full power in a TissueLyser (Qiagen) for 3min. Then we added 360ul of CIA24:1 to each tube and both racks were centrifuged at 4000 RPM for 20min (ThermoScientific SorvallST16). Afterwards the upper phases were transferred carefully to clean rack-wells and 150ul of isopropanol were added to each well and centrifuged at 4000RPM for 20min. The liquid phases were removed and the pellets were washed twice with ethanol 70% and centrifuged at 4000RPM for 5min. Finally the pellets were resuspended in 100ul of RNAse and incubated at 37ºC for 60min. To evaluate the yield and purity, this prococol was compared against results obtained with four commercial extraction kits: DNeasy Plant Han... Presentar Todo
