Genome size in Humulus lupulus L. and H. japonicus Siebold and Zucc. (Cannabaceae)

Sex chromosome differentiation in Humulus japonicus Siebold & Zuccarini, 1846 (Cannabaceae) revealed by fluorescence in situ hybridization of subtelomeric repeat

Humulus japonicus Siebold et Zucc (Japanese hop) is a dioecious species of the family Cannabaceae. The chromosome number is 2n = 16 = 14 + XX for females and 2n = 17 = 14 + XY1Y2 for male. To date, no fluorescence in situ hybridization (FISH) markers have been established for the identification of Humulus japonicus sex chromosomes. In this paper, we report a method for the mitotic and meiotic s...

Assessment report on Humulus lupulus L., flos

Use of laser microdissection for the construction of Humulus japonicus Siebold et Zuccarini, 1846 (Cannabaceae) sex chromosome-specific DNA library and cytogenetics analysis

Dioecy is relatively rare among plant species, and distinguishable sex chromosomes have been reported in few dioecious species. The multiple sex chromosome system (XX/XY1Y2) of Humulusjaponicus Siebold et Zuccarini, 1846 differs from that of other members of the family Cannabaceae, in which the XX/XY chromosome system is present. Sex chromosomes of Humulusjaponicus were isolated from meiotic ch...

Inhibitors of nitric oxide production from hops (Humulus lupulus L.).

Nitric oxide (NO) plays an important role in many inflammatory responses and is also involved in carcinogenesis. In the present study, we investigated the inhibitory effect of extracts from Humulus lupulus L. on both the production of NO and the expression of inducible NO synthase (iNOS) in mouse macrophage RAW 264.7 cells. The production of NO was induced by a combination of lipopolysaccharide...

Predicting Offspring Performance in Hop (Humulus lupulus L

J. Am. Soc. Brew. Chem. 68(3):125-131, 2010 Genetic information for male and female hop accessions is limited, hampering parental selection to maximize offspring productivity. Our objective was to determine whether amplified fragment length polymorphism (AFLP)derived genetic distance (GDmm) estimates and coancestry estimates from pedigrees (GSped) between parental pairs could be used to predict...
