The brown planthopper (BPH) is one of the most serious insect pests of rice. In this study, we conducted a molecular marker-based genetic analysis of the BPH resistance of ’B5’, a highly resistant line that derived its resistant genes from the wild rice Oryza officinalis. Insect resistance was evaluated using 250 F3 families from a cross between ’B5’ and(More)
The ultrastructure of cationic dendronized polymers (denpols) of third and fourth generations (PG3 and PG4) in water was determined by using single-particle cryo-transmission electron microscopy (cryo-TEM). At concentrations in the region of 50 mg L(-1), networks of double-stranded fibers were revealed that exhibit well-defined diameters of 5.9 nm+/-0.4 nm(More)
 Stearoyl-acyl carrier protein (ACP) Δ9-desaturase (Δ9D) from the castor plant is the best characterized soluble acyl-ACP desaturase. This enzyme utilizes a diiron center to catalyze the O2- and NADPH-dependent introduction of a cis double bond between carbons 9 and 10 of stearoyl-ACP, yielding oleoyl-ACP. In the present study, we have used X-ray absorption(More)
Double skin façade (DSF) system is used in high-rise buildings increasingly in the hot summer and cold winter zone in China, due to its advantages in sound proof, aesthetic appearance and energy efficiency. This paper demonstrated a method of obtaining the thermal characteristics of the double skin façade system using computational fluid dynamics (CFD)(More)
 The conversion from methane to methanol is catalyzed by methane monooxygenase (MMO) in methanotrophic bacteria. Earlier work on the crystal structures of the MMO hydroxylase component (MMOH) from Methylococcus capsulatus (Bath) at 4  °C and –160  °C has revealed two different core arrangements for the diiron active site. To ascertain the generality of(More)
Self-assembly of the partially fluorinated rigid molecules physisorbed at solution/graphite interface has been investigated by scanning tunneling microscopy. Upon adsorption, both the branched star-shaped compound 1 and the angulate rod 2 compromising diacetylene and acetylene interlinked benzene and pentafluorobezene formed two-dimensional chiral porous(More)
A tetraethylene glycol ether bridged derivative 9 has been designed and synthesized, and its two-dimensional (2D) self-assembled behavior has been investigated at the single-molecule level. Our results revealed that 9 generally adopted the fully extended state but changed to the contracted state when triggered by K2CO3, and recovered the original fully(More)
Positively charged dendronized polymers with protonated amine groups at the periphery and different dendron generations are cylindrically shaped nanoobjects whose radii and linear charge densities can be varied systematically. These polyelectrolytes have been complexed with DNA and subsequently adsorbed on precoated mica substrates. The analysis of scanning(More)
