Cymbidium goeringii Reichb. fil., locally known as the spring orchid in Republic of Korea, is one most important and popular horticultural species family Orchidaceae. C. cultivars originated from plants with rare phenotypes wild mountains where pine trees commonly grow. This study aimed to determine cultivar-specific combined genotypes (CGs) short sequence repeats (SSRs) by analyzing multiple s...

Little is known about the genetics or genomics of Panax ginseng. In this study, we developed 70 expressed sequence tag-derived polymorphic simple sequence repeat markers by trials of 140 primer pairs. All of the 70 markers showed reproducible polymorphism among four Panax speciesand 19 of them were polymorphic in six P. ginseng cultivars. These markers segregated 1:2:1 manner of Mendelian inher...

The cowpea weevil (Callosobruchus maculatus Fabr.) is the most destructive pest of the cowpea bean; it reduces seed quality. To control this pest, resistance testing combined with genetic analysis using molecular markers has been widely applied in research. Among the markers that show reliable results, the inter-simple sequence repeats (ISSRs) (microsatellites) are noteworthy. This study was pe...

BACKGROUND Resveratrol is an important stilbene that benefits human health. However, it is only distributed in a few species including grape and is very expensive. At present, grape has been an important source resveratrol. However, the details are scarce on resveratrol distribution in different Vitis species or cultivars. METHODOLOGY/PRINCIPAL FINDING The composition and content of resveratr...

Field studies were conducted to determine the potential for alterations in physiology and the intraspecific variation in sensitivity of 20 wheat (Triticum aestivum) cultivars to enhanced ultraviolet-B (UV-B, 280-315 nm) radiation. The supplemental UV-B radiation was 5 kJ m(-2), simulating a depletion of 20% stratospheric ozone. Out of 20 wheat cultivars (from South China, North China and Mexico...

Cultivars collected from similar regions and exhibiting phenotypes to each other are commonly called sister cultivars in spring orchid (Cymbidium goeringii). However, no exact information is available for the original collection places collectors of cultivars, study has revealed degree genetic relationship among them. This was performed determine kinship cultivars. Thirteen flower-variant types...

we prove that the class of profinite groups $g$ that have a factorization $g=ab$ with $a$ and $b$ abelian closed subgroups, is closed under taking strict projective limits. this is a generalization of a recent result by k.h.~hofmann and f.g.~russo. as an application we reprove their generalization of iwasawa's structure theorem for quasihamiltonian pro-$p$ groups.
