During 2011, twigs, leaves and fruits of symptomatic hosts containing Fusicladium species from Guilan, Mazandaran, Qazvin and Ardabil provinces were sampled and examined. Five species including F. carpophilum, F. fraxini, F. oleagineum, F. pomi and F. pyrorum were identified based on morphological data. Of these, F. carpophilum and F. fraxini are identified as new records for the mycobiota of I...

The solution structure of the self-complementary DNA decamer 5'd(CTGGATCCAG)2 comprising the specific target site for the restriction endonuclease BamH1 is investigated by using nuclear magnetic resonance sectroscopy and restrained molecular dynamics. With the exception of the H5'/H5" sugar proton resonances, all the nonexchangeable proton resonances are assigned sequentially by using pure-phas...

Poirier and Reutenauer defined a Hopf algebra on the Z-span of all standard Young tableaux in [10], which is later studied in [4, 11]. The Robinson-Schensted-Knuth insertion was used to relate the bialgebra to Schur functions. Schur function is a class of symmetric functions that can be determined by the summation of all semistandard Young tableaux of shape . With the help of the PR-bialgebra, ...

selection of superior chance seedling genotypes is an important task in pear breeding programs. this research was carried out in order to explore and evaluate some of european pear (pyrus communis l.) chance seedling genotypes that are primarily used as rootstock for the asian pear (pyrus serotina rehd.) in tarbiat modares university (tmu) asian pear collection orchard. after four years visual ...

oxalate soluble pectin (osp) is related to fruit firmness with respect to the chelation of calcium ions with carboxyl groups of adjacent polyuronide chains. this study was carried out to explore the effect of time of fruit harvest, foliar spray with cacl2 during growing season on osp, polygalacturonase activity (pga), fruit firmness and the effects on fruit shelf life, quality and internal ...
