Sorption of phosphate onto mesoporous γ-alumina studied with in-situ ATR-FTIR spectroscopy

Chemistry Central Journal (2012)

Tingting Zheng Zhong-Xi Sun Xiaofang Yang Allan Holmgren

Due to the extensive use of phosphates in industry, agriculture and households, the phosphate - γ-alumina interactions are important for understanding its detrimental contribution to eutrophication in lakes and rivers. In situ Fourier transform infrared (FTIR) spectroscopy can provide more detailed information on the adsorbate-adsorbent interaction and the formation of hydrogen bonds. In situ ATR-FTIR spectroscopy was used to identify phosphate complexes adsorbed within the three-dimensional network of mesoporous γ-alumina at pH 4.1 and 9.0. The integrated intensity between 850 cm-1 and 1250 cm-1 was used as a relative measure of the amount of adsorbed phosphate. The integrated intensity proved to be about 3 times higher at pH 4.1 as compared with the corresponding intensity at pH 9.0. The adsorption of phosphate at the two pH conditions could be well described by the Langmuir adsorption isotherm at low concentrations and the empirical Freundlich adsorption isotherm for the whole concentration range, viz. 5 – 2000 μM. From the band shape of infrared spectra at pH 4.1 and pH 9.0, it was proposed that the symmetry of the inner-sphere surface complex formed between phosphate and γ-alumina was C1 at the lower pH value, whilst the higher value (9.0) implied a surface complex with C2v or C1 symmetry. The difference in adsorbed amount of phosphate at the two pH values was ascribed to the reduced fraction of ≡ AlOH2+ surface sites and the increased fraction of ≡ AlO- sites upon increasing pH from 4 to 9.

The OsmiR396–OsGRF8–OsF3H‐flavonoid pathway mediates resistance to the brown planthopper in rice (Oryza sativa)

Plant Biotechnology Journal (2019)

Zhengyan Dai Jiang Tan Cong Zhou Xiaofang Yang Fang� Yang

Multi-functional microRNAs (miRNAs) are emerging as key modulators of plant-pathogen interactions. Although the involvement of some miRNAs in plant-insect interactions has been revealed, the underlying mechanisms are still elusive. The brown planthopper (BPH) is the most notorious rice (Oryza sativa)-specific insect that causes severe yield losses each year and requires urgent biological control. To reveal the miRNAs involved in rice-BPH interactions, we performed miRNA sequencing and identified BPH-responsive OsmiR396. Sequestering OsmiR396 by overexpressing target mimicry (MIM396) in three genetic backgrounds indicated that OsmiR396 negatively regulated BPH resistance. Overexpression of one BPH-responsive target gene of OsmiR396, growth regulating factor 8 (OsGRF8), showed resistance to BPH. Furthermore, the flavonoid contents increased in both the OsmiR396-sequestered and the OsGRF8 overexpressing plants. By analysing 39 natural rice varieties, the elevated flavonoid contents were found to correlate with enhanced BPH resistance. Artificial applications of flavonoids to wild type (WT) plants also increased resistance to BPH. A BPH-responsive flavanone 3-hydroxylase (OsF3H) gene in the flavonoid biosynthetic pathway was proved to be directly regulated by OsGRF8. A genetic functional analysis of OsF3H revealed its positive role in mediating both the flavonoid contents and BPH resistance. And analysis of the genetic correlation between OsmiR396 and OsF3H showed that down-regulation of OsF3H complemented the BPH resistance characteristic and simultaneously decreased the flavonoid contents of the MIM396 plants. Thus, we revealed a new BPH resistance mechanism mediated by the OsmiR396-OsGRF8-OsF3H-flavonoid pathway. Our study suggests potential applications of miRNAs in BPH resistance breeding.

Modulation of plant architecture by the miR156f–OsSPL7–OsGH3.8 pathway in rice

Journal of Experimental Botany (2018)

Zhengyan Dai Jiang Wang Xiaofang Yang Huan Lü Xuexia Miao

Tiller number and plant height are two of the main features of plant architecture that directly influence rice yield. Auxin and miR156, an extensively studied small RNA (smRNA), are both broadly involved in plant development and physiology, suggesting a possible relationship between the two. In this study, we identified a rice T-DNA insertion cluster and dwarf (cd) mutant that has an increased tiller number and reduced plant height. The T-DNA insertion was in close proximity to the miR156f gene and was associated with its up-regulation. Plants overexpressing miR156f resembled the cd mutant. In contrast, plants overexpressing an miR156f target mimic (MIM156fOE) had a reduced tiller number and increased height. Genetic analysis showed that OsSPL7 is a target of miR156f that regulates plant architecture. Plants overexpressing OsSPL7 had a reduced tiller number, while OsSPL7 RNAi plants had an increased tiller number and a reduced height. We also found that OsSPL7 binds directly to the OsGH3.8 promoter to regulate its transcription. Overexpression of OsGH3.8 and OsGH3.8 RNAi partially complemented the MIM156fOE and cd mutant phenotypes, respectively. Our combined data show that the miR156f–OsSPL7–OsGH3.8 pathway regulates tiller number and plant height in rice, and this pathway may allow crosstalk between miR156 and auxin.
