Virus-derived small interfering RNAs (vsiRNAs) of cucumber green mottle mosaic virus (CGMMV), a member of the genus Tobamovirus, were characterised in cucumber plants by deep sequencing. CGMMV vsiRNAs of 21-22 nt in length predominated, suggesting that there might be a conserved mechanism of DCL2 and DCL4 involvement in the biogenesis of vsiRNAs, as well as(More)
The first complete genome sequence of ISMV was determined by deep sequencing of a small RNA library constructed from ISMV-infected samples and rapid amplification of cDNA ends (RACE) PCR. The ISMV genome consists of 10,403 nucleotides excluding the poly(A) tail and contains a large open reading frame encoding a polyprotein of 3316 amino acids. Putative(More)
Comparisons of soil respiration (RS) and its components of heterotrophic (RH) and rhizospheric (RR) respiration during daytime and nighttime, growing (GS) and dormant season (DS), have not being well studied and documented. In this study, we compared RS, RH, RR, and their responses to soil temperature (T5) and moisture (θ5) in daytime vs. nighttime and GS(More)
A new dendritic gelator with carbazole as the building block (HBCD) was synthesized. It was found that H-bonding between the amide groups and π-π interaction between the aromatic rings played predominant roles in the gel formation. Meanwhile, significant aggregation-induced emission enhancement was observed in the gel state due to the formation of(More)
Pathogens causing significant economic losses in chrysanthemum include tomato aspermy virus (TAV), chrysanthemum virus B (CVB), cucumber mosaic virus (CMV), tobacco mosaic virus (TMV), potato virus Y (PVY), chrysanthemum stunt viroid (CSVd) and chrysanthemum chlorotic mottle viroid (CChMVd). A multiplex reverse transcription polymerase chain reaction(More)
A novel fluorescent Probe 1, based on phenanthro-imidazole has been developed as an efficient chemosensor for the trace detection of copper ions (Cu2+). Probe 1 demonstrated sensitive fluorescence quenching upon binding with Cu2+ through 1:1 stoichiometric chelation. The detection limit for Cu2+ ions was projected through linear quenching fitting to be as(More)
Understory management in forest ecosystems has been applied to improve the wood production for hundreds of years worldwide. The carbon-physiological mechanisms underlying these positive effects of understory management on the growth of overstory trees have received less attention. We studied the non-structural carbohydrate (NSC) and total nitrogen (N)(More)
The aim of this study was to analyze the composition and spatio-temporal variation of soil macroinvertebrate communities in the northern Hengduanshan Mountains, Southwest China. The soil macroinvertebrates were investigated in April, August and November of 2008 in two deciduous broad-leaved forests: secondary shrub forest (SSF) and Betula albosinensis(More)
