Prime Minister a. Halloween Minister of Agriculture m. Roze Ministry of Agriculture presented version of annex 1 of the Cabinet of Ministers of 29 May 2007 by Regulation No 364 of the potato tuber sampling and detection and identification of the organism they shall: 1. sample preparation 1.1. standard sample size is 200 tubers per test. Intense look in sampling tubers gu sample is larger, the test results can be difficult to obtain or to interpret. However, this procedure can easily be used for samples with less than 200 tubers are not available in the quantity required. All validation methods described below is based on sample testing of 200 tubers. The potato extract described below can also be used for detection of the organism; 1.2. additional pre-treatment prior to sample preparation: samples before testing 1.2.1 stand up to 25-30 0 c temperature for up to two weeks to encourage multiplication of all population of the organism; 1.2.2. wash the tubers. Between each sample test to use appropriate disinfectants (when PCR-test, chlorine compounds are used to clear the potential pathogen DNA) and detergents. Allow the tubers to dry. Washing process is particularly useful (but it is not mandatory) for samples with excess soil and if test or PCR test for the direct isolation; 1.3. with a clean and disinfected scalpel or vegetable knife the skin at each remove heel (heel) to reveal the vascular. Carefully cut small pieces of potato from the heel end and try to cut out the non-vascular tissue to a minimum; 1.4. collect the heel end cores or new disposable containers which can be closed or severely (in case containers are reused, they are cleaned and disinfected using chlorine compounds). The heel end recommended process immediately. If this is not possible, they can be stored in a container, adding a buffer is no longer than 72 hours refrigerated for not longer than 24 hours at room temperature. Process the heel ends or pieces, using one of the following procedures: 1.4.1. base or transfuse pieces with sufficient quantity (approximately 40 ml) of extraction buffer (Appendix 6) and shuffle the Rotary shaker (50 to 100 rpm) for four hours at a temperature of no lower than 24 0 c, and 16-24 hours refrigerated; 1.4.2. homogenizing heel ends with a sufficient quantity of (approximately 40 ml) of extraction buffer (Appendix 6) with mixer (Waring or ultra Thurax) or by crushing in a sealed disposable maceration bag (e.g. Stomacher or strong polyethylene Bioreba, 150 mm x 250 mm; sterilized with ionizing radiation) using a rubber mallet or appropriate grinding (e.g. Homex). 1.5. the top layer of the clear supernatant.

Pellet with relatively little starch sediment into the first box, transfer the potato pellet dilution 1/100 (15 µ l box with six millimeter diameter-quantity for larger Windows in proportion to the increase). Then a similar volume of undiluted Pellet (1/1) to transfer the remaining boxes in the row. The second row can be used as duplicate or for a second sample; 2.2.2. other pellet preparing the resuspended pellet decimal dilutions (1/10, 1/100) pellet buffer. Pipette into each box in a row into the same quantity of re-suspended pellet appliance (15 µ l is appropriate for 6 mm window diameter-for larger Windows increase proportionally to the quantity). The second row can be used as duplicate or for a second sample; 2.3. dry the droplets at ambient temperature or heated up to 40-45 ºc. The bacterial cells to the slide by heating (15 minutes at a temperature of 60 0 c), flaming, with 95% ethanol or according to the suppliers of the antibodies for specific instructions. If necessary, fixed slides before further testing can be stored in the frozen form of drying box for the shortest possible period of time (no more than three months); 2.4. IF procedure: 2.4.1. preparation of the test slide according to this annex to point 2.2.1. Prepare a double dilution. In the first box, must be ½ of the titre (T/2), the other-¼ titre (T/4), ½ of the titre (T/2), the titre (T) full and double the titre (2T) (Figure 1); Figure 1 Test slide preparation of resuspended pellet dilution 1/100 1/1 1/1 1/1 1/1 [] of resuspended pellet dilution (T = titre) T/2 T/3 T/2 T 2T [] double dilution of antiserum/antibody 1. sample • 1 • 2 • 3 • 4 • 5 1. duplicate samples or sample 2 • 6 • 7 • 8 • 9 • 10 2.4.2. preparation of the test slide according to paragraph 2.2.2 of this annex. Prepare the working dilution of the antibodies (DA) in IF buffer (Figure 2). The working dilution affects the specificity of determination; Figure 2 Test slide preparation of Antiserum/antibody working dilution 1/1 1/1 10/100 blank empty [] of resuspended pellet decimal 1. sample • 1 • 2 • 3 • 4 • 5 1. duplicate samples or sample 2 • 6 • 7 • 8 • 9 • 10 2.4.3. slides to put on wet paper napkins. Each test box full overlay with the dilution of antibodies. The volume of antibody applied to each box must be at least equal to the volume of the extract. If there is no antibody suppliers of specific instructions, the following procedure should be carried out: 2.4.3.1. slides to treat wet napkins covered way 30 minutes at ambient temperature (18-25 0 c); 2.4.3.2. shake off droplets of each slide and Rinse carefully with IF buffer. Wash for five minutes in IF buffer-Tween dipping (annex 6) and then IF buffer. To avoid aerosol formation or droplet transfer that may result causing contamination. Carefully take excess liquid gently wipe; 2.4.3.3. slides to put on wet paper napkins. Cover the test Windows with the dilution of FITC conjugate used to determine the titre. The volume of conjugate applied on the box must be equal to the volume of antibody used; 2.4.3.4. slides shall pass to the wet napkins covered way 30 minutes at ambient temperature (18-25 0 c); 2.4.3.5. shake off droplets of conjugate slide. Before rinse and wash. Carefully wipe the excess liquid; 2.4.4.7. pipette on each window 5-10 µ l 0.1 M phosphate-buffered glycerol (Appendix 6) or a commercially available color stability enabling the binder and apply a coverslip; 2.5. reading the IF test: 2.5.1. examine test slides on an epifluorescence microscope with filters suitable for working with FITC, water or oil immersion at a magnification of 500 to 1000. The boxes look across two diameters at right angles and around the perimeter. Samples of the cells do not see or appear in small amounts, to examine at least 40 microscope fields; 2.5.2. in the test Windows of the test slides for bright Fluorescing cells with characteristic morphology of the organism. The fluorescence intensity must be equivalent to the positive control strain at the same antibody dilution. Cells with incomplete staining or with weak fluorescence is not taken into account; 2.5.3. take into account the specific size only Fluorescing cells with typical morphology at the titre of the antibodies or the working dilution, as defined in paragraph 2.4 of this annex; 2.6. IF test reading interpretation: 2.6.1. If found bright Fluorescing cells with characteristic morphology, identify specific cell average number of microscope field and calculate the number of typical cells per ml of resuspended pellet in accordance with the provisions of annex 7. IF the test is positive for samples with no less than 5 × 103 typical cells per ml of resuspended Pellet. The following sample is considered potentially infected and needs further testing; 2.6.2. IF test is negative for samples with less than 5 × 103 typical or non-typical cells per ml of resuspended pellet and the sample is considered negative. Further testing is not carried out; 3. PCR test: 3.1 use of validated PCR reagents, respectively, and protocols in accordance with the provisions of Annex 8. It is recommended that you choose a method of internal control. Use appropriate precautions to avoid contamination of the sample with target DNA. The PCR test is carried out in specially equipped molecular biology laboratories, in order to decrease the risk of sample contamination with target DNA. Negative control samples (DNA extraction and PCR) is always used as the definitive procedure to determine whether the DNA transfer has taken place. Include the following in the PCR test negative controls: 3.1.1. sample extract that previously tested negative for the presence of the organism; 3.1.2. buffer controls used for extracting the bacterium and the DNA from the sample; 3.1.3.

Add 500 µ l of chloroform and stir up the viscosity decreases and the mixture becomes homogeneous; 3.2.1.8. centrifuge for 20 min at 4 0 c temperature at 15 000 g to separate phases and form the interphase; 3.2.1.9. transfuse top phase pure microvial; 3.2.1.10. Add 1 ml of 100% ethanol (-20 ° C), mix and 10 min to hold ice; 3.2.1.11. centrifuge for 20 min at 4 0 c temperature at 15 000 g and remove ethanol from pellet; 3.2.1.12. Add 500 µ l 80% ethanol (-20 0 c) and stir flipping; 3.2.1.13. centrifuge for 10 minutes at a temperature of 0 c 15 4 000 g, save the pellet and remove ethanol. 3.2.1.14. allow the pellet to dry in the environment or DNS vakuumžāvētāj; 3.2.1.15. resuspend the pellet in 100 µ l of sterile ultra pure water (UPW) and leave at least 20 min at room temperature; 3.2.1.16. to use PCR to store-20 0 c temperature; 3.2.1.17. spin down any white precipitate by centrifugation and use 5 µ l of the PCR in the clear top layer containing DNA; 3.2.2. other methods. Other DNA extraction methods, such as Qiagen DNeasy plant Kit, may be applied provided that it is demonstrated effectiveness equivalent to DNA from control samples in the treatment that contains 103 to 104 1 ml pathogenic bacteria. 3.3. PCR: 3.3.1. prepare the PCR test and control templates in accordance with the test protocols (annex 8). Prepare one decimal sample DNA extract (1:10 in upw); 3.3.2. in accordance with the published protocols prepare the appropriate PCR REACTION mix in a contamination-free environment (annex 8). If possible, we recommend using a multiplex PCR protocol that also incorporates an internal PCR control; 3.3.3. Add 2-5 µ l DNA extract to 25 µ l PCR reaction in sterile PCR tubes according to PCR Protocols (annex 8); 3.3.4. add negative control containing only PCR reaction mix and add the same grade water originating in what was used in the PCR mix in place of the sample; 3.3.5. Insert tubes in the same either, which was used for prior checking, the Guide and implement the optimized PCR program (annex 8). 3.4. the analysis of the PCR product: 3.4.1 split the PCR Amplicon with agarose gel electrophoresis. Electrophoresis is made with 5-8 cm at least 12 µ g/l DNS propagation reaction mix of each sample mixed with 3 µ l ballast buffer (Appendix 6) in 2.0% (w/v) agarose gels in TRIS-actet-EDTA (Tae) buffer (annex 8). Use the appropriate DNA marker, e.g., 100 bp ladder; 3.4.2. reveal DNA bands, 30b-60 min. dyeing with ethidium bromide (0.5 mg/l), with the mutagenic substances. taking appropriate precautions; 3.4.3. painted with UV gel short-wave transillumination (λ = 302 nm for example) seen stained PCR products size match the expected (annex 8), process document; 3.4.4. for all new finds or cases of authenticity of the PCR Amplicon by performing enzymatic restriction analysis with the remaining amplified DNA samples, the optimum time for optimum temperature can be with an appropriate enzyme and buffer (annex 8). Identify the sections that cracked agarose gel electrophoresis, and the methods listed above and after staining with ethidium bromide to observe characteristic restriction fragment, using UV transillumination. Compare the positive testimony before and after cleavage reactions. 3.5. the PCR test result interpretation: 3.5.1 the PCR test is negative if the body to specific PCR Amplicon of expected size in that pattern is not found, but it detects all in the positive control (case of multiplex PCR with plant specific internal control primers: a second PCR-product of expected size must be amplified with the sample in question); 3.5.2. The PCR test is positive if it is found the special body to PCR Amplicon of expected size with characteristic and restriction (if necessary), provided that it is not derived from any of the negative control samples. Reliable confirmation of a positive result can also be obtained by repeating the test with a second set of PCR primers (annex 8).
