Porous heteroatom-doped carbon materials exhibit promising electrochemical applications because of tunable porous structure and doping heteroatom-induced charge ***,it is still a great challenge to develop porous heteroatom-doped carbon materials with both high-content active heteroatom species and facilitated diffusion ***,we report a bowl-shaped nitrogen and oxygen dual-doping carbon(N,O-doped carbon)material based on low-temperature defluorination pyrolysis and alkali-etched activation of 3-fluorophenol-3-amino-4-hydroxypyridine-formaldehyde co-condensed resin and its excellent *** low-temperature thermal treatment strategy ensures high-content pyrrolic nitrogen(4.6 at.%)and oxygen species(15.9 at.%)to avoid high-temperature treatment-induced heteroatom loss and undesired configuration *** these processes,the defluorination pyrolysis promotes the transformation from the resin to carbon material to some extent,and KOH activation also promotes the ordered arrangement of 002 planes,which together assure the appropriate conductivity of the final microporous carbon *** importantly,KOH-etched activation partially removes an un-stable nano/microscale domain of the intermediate carbon microspheres to form a unique bowl-shaped structure extremely facilitating the diffusion of the substitutes and/or electrolyte *** expected,N,O-doped carbon material displays a remarkable specific capacitance of 486.4 F g^(−1)at 1 A g^(−1)with nitro-gen/oxygen species-dependant pseudocapacitance and good electrochemical durability.

Dear Editor,Pan-genomes with high quality de novo assemblies are shifting the paradigm of biology research in genome evolution,speciation,and function annotation(Shi et al.,2023).An all-vs.-all comparison across assemblies potentially overcomes the limitation of mapping short reads to a single assembly in cataloging polymorphisms,especially large insertions and deletions(indels)contributing to phenotypic variations through altering gene structure or expression(Chen et al.,2021).

Journal of Integrative Plant Biology 2012年第2期54卷 73-86页

作者： bosen zhang Zhiping Jin Daoxin Xie School of Life Sciences TsinghuaUniversityBeijing 100084China MOE Key Laboratory of Bioinformatics Tsinghua UniversityBeijing 100084China State Key Laboratory of Plant Genomics and National Center for Plant Gene Research Institute of Genetics and Developmental BiologyChinese Academy of SciencesBeijing 100101China

In plants, non-coding small RNAs play a vital role in plant development and stress responses. To explore the possible role of non-coding small RNAs in the regulation of the jasmonate （JA） pathway, we compared the non-coding small RNAs between the JA-deficient aos mutant and the JA-treated wild type Arabidopsis via high-throughput sequencing. Thirty new miRNAs and 27 new miRNA candidates were identified through bioinformatics approach. Forty-nine known miRNAs （belonging to 24 families）, 15 new miRNAs and new miRNA candidates （belonging to 11 families） and 3 tasiRNA families were induced by JA, whereas 1 new miRNA, 1 tasiRNA family and 22 known miRNAs （belonging to 9 families） were repressed by JA.

Effects of gallium surfactant on AlN thin films by microwave plasma chemical vapor deposition

Journal of Semiconductors 2024年第9期45卷 53-60页

In this work, AlN films were grown using gallium (Ga) as surfactant on 4° off-axis 4H-SiC substrates via microwave plasma chemical vapor deposition (MPCVD). We have found that AlN growth rate can be greatly improved due to the catalytic effect of trimethyl-gallium (TMGa), but AlN crystal structure and composition are not affected. When the proportion of TMGa in gas phase was low, crystal quality of AlN can be improved and three-dimensional growth mode of AlN was enhanced with the increase of Ga source. When the proportion of TMGa in gas phase was high, two-dimensional growth mode of AlN was presented, with the increase of Ga source results in the deterioration of AlN crystal quality. Finally, employing a two-step growth approach, involving the initial growth of Ga-free AlN nucleation layer followed by Ga-assisted AlN growth, high quality of AlN film with flat surface was obtained and the full width at half maximum (FWHM) values of 415 nm AlN (002) and (102) planes were 465 and 597 arcsec.

Characterization of a novel high-tillering dwarf 3 mutant in rice

Tiller number and culm length are important components of plant architecture and determinate grain production in rice.A line SIL046, derived from an introgression lines population developed by an accession of common wild rice（Oryza rufipogon Griff.） and a high-yielding indica cultivar Guichao 2（Oryza sativa L.）,exhibits a higher tiller number and shorter culm length phenotype than the recipient parent Guichao 2（GC2）.Genetic analysis showed that the high-tillering dwarf phenotype was controlled by a novel single recessive gene,referred to as the high-tillering dwarf 3（htd3）,which located within the genetic distance of 13.4 cM between SSR makers RM7003 and RM277 on chromosome *** means of fine-mapping strategy,we mapped HTD3 gene within the genetic distance of 2.5 cM and the physical distance of 3100 kb in the centromere of chromosome *** identification of HTD3 gene would provide a new opportunity to uncover the molecular mechanism of the development of culm and tiller,two important components of yields in rice.

The bHLH Transcription Factor MYC3 Interacts with the Jasmonate ZIM-Domain Proteins to Mediate Jasmonate Response in Arabidopsis

引用

Molecular Plant 2011年第2期4卷 279-288页

作者： Zhiwei Cheng Li Sun Tiancong Qi bosen zhang Wen Peng Yule Liu Daoxin Xie MOE Key Laboratory of Protein Science School of Life Sciences Tsinghua University Beijing 100084 China

The Arabidopsis Jasmonate ZIM-domain proteins （JAZs） act as substrates of SCF complex to repress their downstream targets, which are essential for JA-regulated plant development and defense. The bHLH transcription factor MYC2 was found to interact with JAZs and mediate JA responses including JA-inhibitory root growth. Here, we identified another bHLH transcription factor MYC3 which directly interacted with JAZs by virtue of its N-terminal region to regulate JA responses. The transgenic plants with overexpression of MYC3 exhibited hypersensitivity in JA-inhibitory root elon- gation and seedling development. The JAZ-interacting pattern and the JA-induced expression pattern of MYC3 were distinguishable from those of MYC2. We speculate that MYC3 and MYC2 may have redundant but also distinguishable functions in regulation of JA responses.
