SNP detection indicated that there were four haplotypes in the hina genes of 92 barley cultivars, and haplotype 01 and 02 were shared buy AL3818 by 68 and 14 cultivars, respectively, suggesting that there was a very limited diversity in hina genes among North American barley cultivars.
Despite the wide range in hardness exists in 92 barley cultivars, however, unlike wheat, where a clear relationship has been demonstrated between a number of SNPs in the wheat hardness genes and quality (soft or hard wheat), there was no such relationship for barley. The genotypes used in this study demonstrated that there was a low level of polymorphism in hina gene in North American barley cultivars and these polymorphisms had no impact on grain hardness.”
“In this investigation, morphological, phytochemical and ISSR markers were used to estimate the relationships among and within seven populations
of white savory (Satureja mutica), belonging to four provinces in Iran. The individuals were phenotypically diverse, which stamen length, corolla length, selleckchem corolla diameter, calyx length, bract length, inflorescence length, calyx length and bracteole width were characteristics with the highest variation. Leaf dimensions were in significant correlation with flower and inflorescence characteristics. Chemical compounds of essential oils were found variable in various individuals and all samples were principally composed of phenolic constituents (carvacrol and/or thymol). As a consequence, the plants were classified into two major chemotypes including carvacrol and thymol. A total of 197 band positions were produced by 14 ISSR primers, of which 176 were found polymorphic with 88.91% polymorphism. ISSR genetic similarity check details values among individuals ranged between 0.45 and 0.94 which was indicative of a high level of genetic variation.
Multiple regression analysis (MRA) revealed that phytochemical compositions as dependent variable, showed statistically significant correlation and in association with leaf and flower traits as independent variable, indicating a main role of leaf and flower on production of these compounds. Also, several ISSR fragments were found associated with some morphological traits and phytochemical compositions. The high diversity within and among populations of S. mutica according to different data systems could provide useful information for conservation and selection of cross-parents in breeding programs.
