Morphological, developmental and electrophoretic variation within and between obligately apomictic Taraxacum species

Interclonal variation in six morphometric characters and in the onset and rate of capitulum production, together with inter-and intra-clonal variation in esterase zymograms was examined in each of the two obligately apomictic species, Taraxacum pseudohamatum (section Hamata ) and T. unguilobum (section Naevosa ). Interclonal and interspecific variation in esterase zymograms was also examined within and between seven additional obligately apomictic species within the section Hamata. Within T. pseudohamatum , interclonal variation in the morphometric and electrophoretic characters was extensive; no variation was recorded in the onset and rate of capitulum production. Within T. unguilobum , interclonal variation in the morphometric characters and in the onset and rate of capitulum production was recorded; five of the six clones electrophoretically assayed shared the same esterase zymogram but one of these clones contained an individual which exhibited an aberrant zymogram. Within the section Hamata , considerable variation in esterase zymograms was recorded; this variation was both inter-and intra-specific although one zymogram predominated, being represented in each species and in 65% of the clones.     

Study on the Esterase Isozyme from the Related Citrus Plants

In this experiment, the polyacrylamide gel electrophoresis is adopted to test the esterase isozyme of seeds and seedling of the fourteen species of related Citrus plants. The relationship with each other is analysed according to the resutls of zymogram and scanning chart. The data show that there are differences of various degrees in the number of the isozyme bands, the enzyme activity, the migration of enzymes and their chromatogram scanning. The isozyme of the same species has different forms of expression in the different period of development. The esterase isozyme zymogram of the Citrus seed is generally stable. It can be used as the biochemical and genetical index to detemine the genetic ralationship of Citrus.     

Zymograms and histochemistry of non-specific esterase in the salivary glands

Summary Zymogramic analysis of esterase in the mouse, rat and guinea-pig salivary glands was undertaken and demonstrated species and organ specificities of esterase with electrophoretic method. Salivary glands esterase was classified into A, B and C types based on the electrophoretic mobility. Mouse submandibular gland had the most complicated pattern, while guinea-pig showed the simpliest patterns which was devoid of B type of esterase. Rat salivary glands exhibited rather regular patterns. Similar zymogram patterns were obtained with many kinds of ester compounds, that is simple and substituted naphthol esters and indoxyl derivatives. The tests of inhibition and activation for esterase activity was obtained. Histochemical properties applied to inhibitor test in the esterase zymogram patterns showed no marked differences between ducts and acini.

Variation and distribution of esterase isozymes inHeteranthelium andTaeniatherum of the tribe triticeae,gramineae

Esterase isozyme variations ofHeteranthelium piliferum, Taeniatherum asperum andT. crinitum collected in Iraq, Turkey and Iran were analysed by gel isoelectric focusing. InH. piliferum two types of esterase zymogram, H1 and H2, were found. It was demonstrated that a pair of allelic genes, which is shown in the heterozygotes, controls the difference between type H1 and H2. Two types of esterase zymogram, T1 and T2, were observed in two species ofTaeniatherum. The majority of strains having type H1 ofH. piliferum and type T1 ofT. crinitum was distributed in the highly elevated plateau of the Anatolian and Iranian highlands, while strains with H2 and T2 of these two species were found in the western foot-hills of the Zagros Mountains, the Tigris basin of Mesopotamia and the central Anatolian plateau.
