The fresh new matchmaking between parameters of genetic (P

Towns away from Platanthera chlorantha (PS1 and you can PS2, PB1–PB4, circles) and you can Cephalanthera rubra (CK1 and you may CK2, CB1–CB7, triangles) communities in north-eastern Poland.

Analysis city and you may sampling

I examined six P. chlorantha and you may nine C. rubra populations in northern-eastern Poland (Bialowieza and you will Knyszynska Primeval Tree, Szeszupa river area) during the absolute, semi-pure and you will anthropogenic groups from national and you may surroundings parks, supplies and you will secure elements, like Natura 2000 web sites ( Fig. 1). Despite the reality they are situated in secure components, of many exists towards the railway embankments, along roads and routes for the forests or even in clearings.

This new testing process depended to your population dimensions. Leaf samples regarding most ramets inside communities of every varieties was taken (except inhabitants PS2; Desk step one); zero samples was obtained from damaged or very younger people. A hundred and you may ninety-seven trials off P. chlorantha and you may 95 products away from C. rubra were accumulated. Leaf muscle are continued frost up to it can be held at the ?80 °C, pending allozyme study. All collected products were used to have allozyme study.

N, population size; N_S, number of samples analysed; N_Grams/N_W, number of generative ramets/number of vegetative ramets; P_POL, percentage of polymorphic loci; A, mean number of alleles per locus; H_O, observed heterozygosity; H_E, expected heterozygosity; F_Are, inbreeding coefficient; G, number of genotypes, G/N_S, clonal diversity; G_U, number of unique genotypes; G_U %, percentage of unique genotypes (Fischer’s exact test: P < 0.05, **P < 0.01, ***P < 0.001); #, sum of parameters.

Allozyme polymorphism

Homogenates was basically prepared by milling the new will leave in a barrier having 2-mercaptoethanol (1%, v/v). Electrophoresis are achieved on the 10% starch gels and Titan III cellulose acetate dishes (Helena Laboratories, Beaumont, Texas, USA) following the important electrophoretic tips. Ten loci https://datingranking.net/vietnamese-dating/ (Adh, Gdh, Got-step 1, Got-2, Idh-step one, Idh-2, Mdh-1, Mdh-dos, Me, Pgi, Pgm, 6Pgd, Skd, Sod, Tpi) for the P. chlorantha and sixteen loci for the C. rubra (Adh, Got-1, Got-dos, Gdh, Idh-step 1, Idh-dos, Mdh-step 1, Mdh-dos, Me, 6Pgd, Pgi, Pgm, Skd, Sod, Tpi-step 1, Tpi-2) have been investigated. One or two electrode/serum boundary possibilities were utilized to resolve chemical possibilities: GDH and Had (10% lithium-borate lateral starch gel at the pH 8.2/8.3) and you may MDH, SKD and you may TPI (10% histidine-citrate boundary at the pH 7.0/7.0). Chemical pastime staining then followed Soltis Soltis ( 1989). Additional chemical possibilities (ADH, IDH, Me personally, 6PGD, PGI, PGM, SOD) was in fact processed having fun with Titan III cellulose acetate plates, that happen to be resolved playing with Tris-glycine shield from the pH 8.6 and Tris-citrate buffer at the pH 7.6 (Richardson, Adams Baverstock, 1986). Brand new chemical staining treatments had been predicated on Soltis Soltis ( 1989) and you will Richardson mais aussi al. ( 1986), with adjustment.

Statistical studies

The data matrix of individuals was analysed using the TFPGA package (Miller, 1997), FSTAT 2.9.3 (Goudet, 2001) and GENEPOP 3.2 (Raymond Rousset, 1995) for calculation of standard measures of allozyme diversity: allelic frequencies, percentage of polymorphic loci (P_POL), number of alleles per locus (A), genetic diversity (i.e. observed H_O and expected heterozygosity H_E) and inbreeding coefficient (F_Are). The occurrence of unique alleles was used to describe population distinctiveness (Slatkin, 1985). Deviations from Hardy–Weinberg expectations were tested for the population by the Markov chain method (GENEPOP).

Parameters of within-population genotypic diversity were also estimated. Three different measures of clonal diversity were used: number of observed genotypes (G), number of genotypes unique to a single population (G_U) and the probability that the next ramet sampled would be a different genotype (G/N_S; where N_S is the number of ramets sampled). _POL, A, H_O and F_Try) and population size were tested with Spearman’s pairwise rank correlations (StatSoft, 1995).
