Low-temperature germination is one of the major determinants for stable stand establishment in the direct seeding method in temperate regions, and at high altitudes of tropical regions. Quantitative trait loci (QTLs) controlling low-temperature germinability in rice were identified using 122 backcross inbred lines (BILs) derived from a cross between(More)
A laccase (EC was isolated from the culture filtrate of Lentinula edodes. The enzyme was purified to a homogeneous preparation using hydrophobic, anion-exchange, and size-exclusion chromatographies. SDS-PAGE analysis showed the purified laccase, Lcc 1, to be a monomeric protein of 72.2 kDa. The enzyme had an isoelectric point of around pH 3.0. The(More)
Plastid DNA (ptDNA) in albino rice plants regenerated from pollen by anther culture was investigated by Southern blotting. Of the 20 albino plants investigated, 7 contained ptDNA that had suffered large-scale deletion. The size and location of the deletions differed among the plants. In all cases about 30 kbp of the region containing the PstI-2 fragment(More)
To construct a vector for high-level expression of heterologous genes in Lentinus edodes, the L. edodes GPD promoter, which is expressed constitutively and strongly, was fused to a hygromycin B phosphotransferase gene (hph) derived from Escherichia coli as a selective marker. Using the resulting pLG-hph construct, L. edodes was efficiently transformed to(More)
A detailed study of the lymphatics around the pancreas was carried out in order to provide a theoretic basis for ideal lymph-node resection in radical cancer operations. The following results were obtained as a result of minute macroscopic dissection of the lymphatics. Three major pathways are identified on the anterior surface of the head of the pancreas.(More)
During dissection practice in 1993 and 1995 to 1999, we found an aberrant muscle which connected the first costal cartilage and the superior margin of the scapula in 12 sides (4.8%) of 11 cadavers (8.9%) among 248 sides of 124 cadavers. The muscle originated from the cranial surface of the sternal end of the first rib, ran laterodorsally, and inserted into(More)
Chronic pain on the ventral surface of the scrotum and the proximal ventro-medial surface of the thigh especially in athletes has been diagnosed in various ways; recently, in Europe the concept of “sports hernia” has been advocated. However, since few reports discuss the detailed course of the nerves in association with the pain, we examined the cutaneous(More)
A 46-year-old woman presented acute sensori-motor neuropathy of the Guillain-Barré type, followed by a protracted course of profound autonomic and sensory dysfunction. Tests of autonomic functions showed denervation hypersensitivity. Neuropathologically, the trigeminal sensory nuclei, solitary nucleus, the dorsal columns of the spinal cord and dorsal spinal(More)
The striated sphincter of the male urethra, the so-called rhabdosphincter, contributes significantly to urethral closure pressure. It is generally agreed that the somatic nerve fibers from the pudendal nerve innervate the rhabdosphincter, and the autonomic nerve fibers innervate the smooth muscle of the urethra. Although it is difficult to clearly identify(More)
Detailed examinations were performed in ten temporal muscles from five cadavers to identify the muscle bundle arrangements of the temporalis and their innervation. Three additional muscle bundles were clearly observed in the main part of the fan-shaped temporalis: the anteromedial, anterolateral, and mid-lateral muscle bundles. Based on the origins,(More)
