    Description: In this article, we report on electrostatically self‐assembled thin films prepared by the alternative immersion of quartz‐coated and indium tin oxide coated glass substrates in aqueous solutions of a copolymer of poly(4‐styrenesulfonic acid‐‐maleic acid) (PSSMA) and a hemicyanine of ()−1,1′‐(propane‐1,3‐diyl)bis{4‐[4‐(dimethylamino)styryl]pyridinium} bromide (HBr). The films were studied by means of ultraviolet–visible absorption and X‐ray photoelectron spectroscopies, scanning electron microscopy, and photoelectrochemical measurements. When irradiated with white light, the PSSMA/H monolayer film gave a stable cathodic photocurrent.

    Description: A electrostatic thin film of an europium-substituted tungstoborate anion with a dinuclear ruthenium(II) complex cation is prepared layer-by-layer as evidenced by ultraviolet–visible absorption spectroscopy. The surface confined good redox behaviors of the cation and anion in the films were observed. The films showed stable and large cathodic photocurrent with a maximum photocurrent density of 2.66 μA cm was achieved for 4 layer film at an applied potential of −0.3 V versus SCE, which is 2.28 folds as great as that of similar film with an inert polymer layer instead of the anion layer. A new electrostatically self-assembled hybrid film consisting of alternating layers of europium-substituted tungstoborate anion of [Eu(BW O ) ] (EuBW) and dinuclear ruthenium(II) polypyridyl complex cation of [(bpy) Ru(BPBH)Ru(bpy) ] {in which bpy = 2,2′-bipyridine and BPBH = 1,6-bis-(2-(2-phenyl)benzimidazoyl)hexane, RuBPBH} was successfully prepared. UV–vis absorption spectroscopy provided the evidences for the layer-by-layer deposition of EuBW anion and RuBPBH cation on quartz substrate. The (EuBW/RuBPBH) films showed stable electrochemical and photoelectrochemical properties with a photocurrent density of 2.66 μA/cm being found for a 4-layer film of (EuBW/RuBPBH) , while irradiated with polychromatic light (325 nm 〈 〈 730 nm) at an applied potential of −0.3 V versus saturated calomel electrode. The enhanced photocurrent generation by presence of the EuBW layer in this hybrid film has also been demonstrated as compared to the (PSS- -MS/RuBPBH) film by using a photoelectrochemical inactive polyanion of PSS- -MS instead of the EuBW anion.

    Description: In this study, the full-length cDNA of the UDP-glucose pyrophosphorylase gene was isolated from jute by homologous cloning (primers were designed according to the sequence of gene of other plants) and modified RACE techniques; the cloned gene was designated . Using bioinformatic analysis, the gene was identified as a member of the gene family. Real-time PCR analysis revealed differential spatial and temporal expression of the gene, with the highest expression levels at 40 and 120 d. PCR and Southern hybridization results indicate that the gene was integrated into the jute genome. Overexpression of gene in jute revealed increased height and cellulose content compared with control lines, although the lignin content remained unchanged. The results indicate that the jute gene participates in cellulose biosynthesis. These data provide an important basis for the application of the gene in the improvement of jute fiber quality.

    Description: Three inorganic/organic hybrid films consisting of sandwich-type tetrazinc(II) tungstophosphorate [P₂W₁₈Zn₄(H₂O)₂O₆₈]¹⁰⁻ (P₂W₁₈Zn₄) and three hemicyanines of (E)-1,1′-(propane-1,3-diyl) bis (4-((E)-2-(4-(dimethylamino) naphthalen-1-yl) vinyl)-pyridinium) bromide (N³), (E)-1,1′-(hexane-1,6-diyl) bis (4-((E)-2-(4-(dimethylamino) naphthalen-1-yl) vinyl) pyridinium) bromide (N⁶), and (E)-1,1′-(decane-1,10-diyl) bis (4-((E)-2-4-(dimethylamino) naphthalen-1-yl) vinyl) pyridinium) bromide (N¹⁰), were prepared by electrostatic self-assembly technique. The UV–visible spectra showed that three inorganic–organic hybrid films of P₂W₁₈Zn₄/Nᵃ (a=3, 6, 10) were uniformly deposited and the hemicyanine molecules formed J-aggregations in the films. The monolayer (P₂W₁₈Zn₄/N³,⁶,¹⁰)₁ films exhibited stable, large cathodic photocurrent densities of 1.41–4.62μA/cm² that strongly depended on the alkyl chain lengths, while irradiated with 100mW/cm² polychromatic light of 730nm〉λ〉325nm at an applied potential of −0.3V vs. saturated calomel electrode. The photocurrent action spectra indicated that the cathodic photocurrents were generated by the charge transfer excitation of the hemicyanines in the films. The effects of applied bias voltages, electron acceptor added into the electrolyte solution, and layer numbers of the (P₂W₁₈Zn₄/Nᵃ)ₙ films on photocurrent generation of (P₂W₁₈Zn₄/Nᵃ)ₙ film were also examined. ; p. 162-169.

    Description: Jute, comprising white and dark jute, is the second important natural fiber crop after cotton worldwide. However, the lack of expressed sequence tag-derived simple sequence repeat (EST-SSR) markers has resulted in a large gap in the improvement of jute. Previously, de novo 48,914 unigenes from white jute were assembled. In this study, 1,906 EST-SSRs were identified from these assembled uingenes. Among these markers, di-, tri- and tetra-nucleotide repeat types were the abundant types (12.0%, 56.9% and 21.6% respectively). The AG-rich or GA-rich nucleotide repeats were the predominant. Subsequently, a sample of 116 SSRs, located in genes encoding transcription factors and cellulose synthases, were selected to survey polymorphisms among12 diverse jute accessions. Of these, 83.6% successfully amplified at least one fragment and detected polymorphism among the 12diverse genotypes, indicating that the newly developed SSRs are of good quality. Furthermore, the genetic similarity coefficients of all the 12 accessions were evaluated using 97 polymorphic SSRs. The cluster analysis divided the jute accessions into two main groups with genetic similarity coefficient of 0.61. These EST-SSR markers not only enrich molecular markers of jute genome, but also facilitate genetic and genomic researches in jute.
