BACKGROUND The recent determination of complete chloroplast (cp) genomic sequences of various plant species has enabled numerous comparative analyses as well as advances in plant and genome evolutionary studies. In angiosperms, the complete cp genome sequences of about 70 species have been determined, whereas those of only three gymnosperm species, Cycas(More)
We studied the seawater carbon dioxide (CO 2) system in the Palau coral reef by measuring total alkalinity (TA) and total dissolved inorganic carbon (DIC). Variation in the CO 2 system on the reef flat and in the lagoon was analyzed by TA–DIC diagrams, taking into accounts the differing residence times of seawater. CO 2 in the offshore water was relatively(More)
When considering the genetic implications of immigrant gene flow, it is important to evaluate both the proportions of immigrant gametes and their genetic composition. We simultaneously investigated paternal and maternal gene flow in dispersed seeds in a natural population of Pinus densiflora located along a ridge. The paternity and maternity of a total of(More)
Pine wilt disease is caused by the pine wood nematode, Bursaphelenchus xylophilus, which threatens pine forests and forest ecosystems worldwide and causes serious economic losses. In the 40 years since the pathogen was identified, the physiological changes occurring as the disease progresses have been characterized using anatomical and biochemical methods,(More)
The Cell Broadband Engine Architecture (CBEA) is a novel microprocessor architecture designed to provide power-efficient and cost-effective high-performance processing for some of the world's most demanding applications, including next generation game consoles. Applications that show special promise of benefiting from CBEA are medical imaging, security and(More)
Wogon-Sugi has been reported as a cytoplasmically inherited virescent mutant selected from a horticultural variety of Cryptomeria japonica. Although previous studies of plastid structure and inheritance indicated that at least some mutations are encoded by the chloroplast genome, the causative gene responsible for the primary chlorophyll deficiency in(More)
Genome-wide association studies (GWAS) are an alternative to bi-parental QTL mapping in long-lived perennials. In the present study, we examined the potential of GWAS in conifers using 367 unrelated plus trees of Cryptomeria japonica D. Don, which is the most widely planted and commercially important tree species in Japan, and tried to detect significant(More)
