Two barley (Hordeum vulgare L.) cultivars with different peroxidase isozyme patterns were studied using polyacrylamide-slab electrophoresis at pH 4.75 to separate the enzymes, and 3-amino-9-ethyl carbazole or o-dianisidine as hydrogen donors to detect peroxidase isozymes. Peroxidase isozyme patterns of extracts of very immature kernels up to 19 days post-anthesis were quite different from isozyme patterns from extracts of more mature kernels. During malting, the peroxidase isozymes of mature barely persisted in green malt, but an additional isozyme was detected in malt after 3 days of germination. Immature kernels with peroxidase isozyme patterns identical to those found in mature kernels for each barley cultivar were dissected into different tissue fractions including husks, pericarp, "green layer," aleurone, endosperm, embryo and scutellum. Electrophoresis of extracts of these tissues revealed the anatomical location of most of the peroxidase enzymes in the whole kernels of the two cultivars.

A histological comparison of the L9, K, P, P1, P2, and P3 genotypes in flax revealed differences in their expression of incompatibility. K and P1 were only moderately incompatible, whereas P, P2, and P3 were highly incompatible, restricting fungal development completely by the 4th day after inoculation. Host cell necrosis was delayed until day 3 in P3 and day 2 in P2; it was present at day 1 in P. Peroxidase, using guaiacol as a proton donor, was detected in P after 2 days, in K at 5 days, and in L9 after 7 days. Soluble peroxidase activity increased in the rusted P genotype from day 3 and from day 7 in K. Gel electrophoresis of infected P revealed a new peroxidase isozyme at 6 days after inoculation. Three new protein bands were also detected at this stage. In 3- and 4-day-old rusted P, peroxidase was detected in the host cell walls of tissue surrounding necrotic infection sites. It was not located in the host cell walls of the compatible L9 genotype at this stage. Lignin was detected histochemically in P after 2 days, in K after 5 days, and in L9 after 9 days. The Wiesner, Maiile, and KMnO4 tests gave equivalent results. Suberin was detected in P, K, and L9 at the same time that lignin became observable.

Optimal Sampling Time

Isoelectric focusing is an effective and well reproducible method to provide information for identification of various plant species and clones if breeding or other genetic modification(s) for a given species are reflected in changes of an isozyme pattern. The method has been used for characterization of plant proteins and enzymes and for identification of various species and varieties. Our aim was to continue our several-year-work carried out on a wide variety of grapevine varieties and to reveal whether analyses of esterase and peroxidase isozyme patterns are suitable to distinguish various grapevine varieties. Therefore we compared esterase and peroxidase isozyme patterns of various species. Plant samples were obtained from Szigetcsep, Kecskemet, Tokaj and Eger. The following samples were analyzed: Pinot gris, noir, blanc, Chardonnay, Riesling Theses, Chasselas from Szigetcs6p, Bianca and his parents Eger2 and Bouvier from Kecskemet, Furmint and Hárslevelű from Tokaj, Kékfrankos and Zweigelt from Eger. To identify various species according to their esterase isozyme patterns the after blooming phenological phase while according to their peroxidase isozyme pattern the dormant phenological phase was found as optimal sampling time.

Apple Cultivars

Anionic electrophoretic isozyme patterns of peroxidase, esterase and acid phosphatase and cationic peroxidase isozyme patterns from shoot bark protein extracts were used to identify clonal apple scion cultivars. Each of the 21 cultivars included in this study developed a unique combination of isozyme patterns which allowed it to be distinguished from the others. Sports within cultivars exhibited identical patterns of enzymes, with the exception of ‘Wijcik’, a natural compact mutant of ‘McIntosh’ which could be distinguished from the latter, although it was indistinguishable from the cultivar ‘Spartan’. Isozyme patterns remained constant when samples were taken from wood of different ages, at several times of the year and with trees growing in different locations and on different rootstocks.
