Brown planthopper(BPH) is one of the most serious and destructive insect pests of rice in most rice growing regions of the world. In this study, two major resistance genes against BPH have been identified in an Oryza rufipogon (Griff.) introgression rice line, RBPH54. Inheritance of the BPH resistance in RBPH54 was studied by screening the resistance in(More)
SmB6, a well-known Kondo insulator, exhibits a transport anomaly at low temperature. This anomaly is usually attributed to states within the hybridization gap. Recent theoretical work and transport measurements suggest that these in-gap states could be ascribed to topological surface states, which would make SmB6 the first realization of topological Kondo(More)
To investigate the effects of dietary copper (Cu) on fish growth, digestive and absorptive enzyme activities, and antioxidant status in the hepatopancreas and intestine, young grass carp (Ctenopharyngodon idella) (282±2.8 g) were fed six diets containing 0.74 (basal diet), 2.26, 3.75, 5.25, 6.70, and 8.33 mg Cu /kg diet for 8 weeks. Results showed that(More)
Introduction: In future manned lunar missions, the ability of suface-based astronauts to remain spatially oriented on the lunar surface can have a serious impact on mission success and safety [1]. Astronauts may become disoriented due to low gravity, tenuous atmosphere , the fractal geometric properties of lunar re-golith, lack of visual cues and(More)
Plant tissue culture, as a fundamental technique for genetic engineering, has great potential of epigenetic variation, of which DNA methylation is well known of importance to genome activity. We assessed DNA methylation level of explants during tissue culture of Brassica napus (cv. Yangyou 9), using high-performance liquid chromatography (HPLC) assisted(More)
The unconventional superconductivity in the newly discovered iron-based superconductors is intimately related to its multiband/multiorbital nature. Here we report the comprehensive orbital characters of the low-energy three-dimensional electronic structure in BaFe 1.85 Co 0.15 As 2 by studying the polarization and photon-energy dependence of angle-resolved(More)
A number of nonlinear microbial models of soil carbon decomposition have been developed. Some of them have been applied globally but have yet to be shown to realistically represent soil carbon dynamics in the field. A thorough analysis of their key differences is needed to inform future model developments. Here we compare two nonlinear microbial models of(More)
YbB6 is recently predicted to be a moderately correlated topological insulator, which provides a playground to explore the interplay between correlation and topological properties. With angle-resolved photoemission spectroscopy, we directly observed almost linearly dispersive bands around the time-reversal invariant momenta and with negligible kz(More)
The garden chrysanthemum (Chrysanthemum × morifolium) variety “Aoyunhuoju” (2n = 6x = 54) was crossed as female with Ajania pacifica (2n = 10x = 90) to produce intergeneric F1 hybrids, which were used both as the source of F2 generation and as the parent for a first back-cross with “Aoyunhuoju”. The morphology of all of the F1 hybrids and hybrid derivatives(More)
Soybean is recognized as one of the plants which are very difficult to be transformed. Considering the low transformation efficiency of soybean, we aimed to determine the effect of 6-benzylaminopurine (6-BA), shoot induction time, and infection time of Agrobacterium on the clonal propagation of Glycine max. Results showed that 1.6 mg/L 6-BA could be optimal(More)
