Ancient DNA recovered from 16 Jomon skeletons excavated from Funadomari site, Hokkaido, Japan was analyzed to elucidate the genealogy of the early settlers of the Japanese archipelago. Both the control and coding regions of their mitochondrial DNA were analyzed in detail, and we could securely assign 14 mtDNAs to relevant haplogroups. Haplogroups D1a, M7a, and N9b were observed in these individ...

Fusarium head blight (FHB), caused by Fusarium graminearum, is a very important disease of wheat globally. Damage caused by F. graminearum includes reduced grain yield, reduced grain functional quality, and results in the presence of the trichothecene mycotoxin deoxynivalenol in Fusarium-damaged kernels. The development of FHB resistant wheat cultivars is an important component of integrated ma...

F-box protein is a core component of the ubiquitin E3 ligase SCF complex and is involved in the gibberellin (GA) signaling pathway. To elucidate the molecular mechanism of GA signaling in wheat, three homologous GIBBERELLIN-INSENSITIVE DWARF2 genes, TaGID2s, were isolated from the Chinese Spring wheat variety. A subcellular localization assay in onion epidermal cells and Arabidopsis mesophyll p...

Abstract Genetic susceptibility to late maturity alpha-amylase (LMA) in wheat ( Triticum aestivum L.) results increased activity mature grain when cool conditions occur during maturation. Farmers are forced sell with elevated at a discount because it has an risk of poor end-product quality. This problem can result from either LMA or preharvest sprouting, germination on the mother plant rain occ...

The role of drug efficacy in agonist-induced desensitization was studied in C-6 glioma cells transfected with the monkey dopamine D1A (mD1A) receptor. Dopamine pretreatment for 2 hr produced greater than 80% loss of responsiveness in the stimulation of cAMP accumulation that was blocked by the D1 antagonist SCH23390. A series of full and partial D1 agonists from structurally dissimilar classes ...

Cell surface gangliosides are shed by tumors into their microenvironment. In this study they inhibit cellular immune responses, including APC development and function, which is critical for Th1 and Th2 cell development. Using human dendritic cells (DCs) and naive CD4(+) T cells, we separately evaluated Th1 and Th2 development under the selective differentiating pressures of DC1-inducing pertuss...

Wheat landraces carry abundant genetic variation in heading and flowering times. Here, we studied flowering-related traits of two Nepalese varieties, KU-4770 and KU-180 and a Japanese wheat cultivar, Shiroganekomugi (SGK). These three wheat varieties showed similar flowering time in a common garden experiment. In total, five significant quantitative trait loci (QTLs) for three examined traits, ...

Microglia and astrocytes play important role in maintaining the homeostasis of central nervous system (CNS). Several CNS impacts have been postulated to be associated with radiofrequency (RF) electromagnetic fields exposure. Given the important role of inflammation in neural physiopathologic processes, we investigated the pro-inflammatory responses of microglia and astrocytes and the involved m...

In soybean, genic male sterility can be utilized as a tool to develop hybrid seed. Several male-sterile, female-fertile mutants have been identified in soybean. The male-sterile, female-fertile ms5 mutant was selected after fast neutron irradiation. Male-sterility due to ms5 was associated with the "stay-green" cotyledon color mutation. The cotyledon color trait in soybean is controlled by two ...
