Japanese gentians (Gentiana triflora and Gentiana scabra) are amongst the most popular floricultural plants in Japan. However, genomic resources for Japanese gentians have not yet been developed, mainly because of the heterozygous genome structure conserved by outcrossing, the long juvenile period, and limited knowledge about the inheritance of important(More)

We developed molecular markers for discrimination of white and blue flower color in Japanese gentian plants. White-flowered gentians can be classified into two types, based on genetic and physiological features. One type includes four allelic variations (gtmyb3-1, gtmyb3-2, gtmyb3-3, and gtmyb3-4) of an anthocyanin biosynthetic regulator gene (GtMYB3),(More)
Overwinter survival has to be under critical regulation in the lifecycle of herbaceous perennial plants. Gentians (Gentiana L.) maintain their perennial life style through producing dormant and freezing-tolerant overwinter buds (OWBs) to overcome cold winter. However, the mechanism acting on such an overwinter survival and the genes/proteins contributing to(More)
Factors affecting reliable plant regeneration from unfertilized ovule culture of gentians (Gentiana spp.) were examined. Cold pretreatment (4°C) of flower buds enhanced or maintained production of embryo-like structure (ELS). When 43 genotypes were surveyed in two different labs, 40 of them produced ELSs ranging from 0.01 to 26.5 ELSs per flower bud. No(More)
Brown leaf spot caused by Mycochaetophora gentianae is a serious disease on gentian in Japan. Previous studies revealed that Gentiana triflora cultivars were susceptible to M. gentianae and that G. scabra cultivars and their interspecific hybrid cultivars were resistant. We subsequently analyzed the mode of inheritance of resistance to M. gentianae in(More)
SUMMARY The Finite-Difference Time-Domain (FDTD) technique is presented in this paper as an estimation method for radio propagation prediction in large and complex wireless local area network (WLAN) environments. Its validity is shown by comparing measurements and Ray-trace method with FDTD data. The 2GHz (802.lIb/g) and 5GHz (802.lIa) frequency bands are(More)
