| 1 | Phosphorylation of a wheat aquaporin at two sites enhances both plant growth and defense显示文摘Eukaryotic aquaporins share the characteristic of functional multiplicity in transporting distinct substrates and regulating various processes,but the underlying molecular basis for this is largely unknown.Here,we report that the wheat(Triticum aestivum)aquaporin TaPIP2;10 undergoes phosphorylation to promote photosynthesis and productivity and to confer innate immunity against pathogens and a generalist aphid pest.In response to elevated atmospheric CO_(2)concentrations,TaPIP2;10 is phosphorylated at the serine residue S280 and thereafter transports CO_(2)into wheat cells,resulting in enhanced photosynthesis and increased grain yield.In response to apoplastic H_(2)O_(2) induced by pathogen or insect attacks,TaPIP2;10 is phosphorylated at S121 and this phosphorylated form transports H_(2)O_(2) into the cytoplasm,where H_(2)O_(2)intensifies host defenses,restricting further attacks.Wheat resistance and grain yield could be simultaneously increased by TaPIP2;10 overexpression or by expressing a TaPIP2;10 phosphomimic with aspartic acid substitutions at S121 and S280,thereby improving both crop productivity and immunity. | Kai Lu Xiaochen Chen Xiaohui Yao Yuyan An Xuan Wang Lina Qin Xiaoxu Li Zuodong Wang Shuo Liu Zhimao Sun Liyuan Zhang Lei Chen Baoyan Li Baoyou Liu Weiyang Wang Xinhua Ding Yonghua Yang Meixiang Zhang Shenshen Zou Hansong Dong | 2022 | Molecular Plant2022，15，11： | 2 |
| 2 | An HPLC Fingerprint Identification of Dried Barks of Ilex rotunda and Ilex godajam显示文摘[Objectives] A simple and reliable HPLC fingerprint method was developed for the identification of dried barks of Ilex rotunda and I. godajam. [Methods] Nine batches of dried barks of I. rotunda,and seven batches of dried barks of I. godajam collected from different pharmacies and arboretums in different regions of China were used to establish fingerprints. The software Similarity Evaluation System of Chromatographic Fingerprints of Traditional Chinese Medicine( 2004 A Edition) was used to evaluate the fingerprints. [Results]The fingerprints of dried barks of I. rotunda and I. godajam were established. Methodological study met the technical requirements of fingerprints. The similarities of the fingerprints of dried barks of I. rotunda and I. godajam were all more than 0. 8 and 0. 9 respectively. There were 31 and 28 common peaks in I. rotunda and I. godajam,which could be classified into two clusters by principal component analysis( PCA) and hierarchical cluster analysis. [Conclusions] The feasibility and advantages of used HPLC fingerprints were verified,and the results indicated that the HPLC fingerprint as a characteristic distinguishing method combining similarity evaluation,principal component analysis and hierarchical cluster analysis can be successfully used to identify the authenticity of dried barks of I. rotunda and I. godajam. | Yucui MA Chun WANG Wei WANG Cui WU Ning DU Wen SUN Hui LI Zhimao CHAO | 2018 | Medicinal Plant2018，9，3： | 0 |
| 3 | MYB44 regulates PTI by promoting the expression of EIN2 and MPK3/6 in Arabidopsis显示文摘The plant signaling pathway that regulates pathogen-associated molecular pattern(PAMP)-triggered immunity(PTI)involves mitogen-activated protein kinase(MAPK)cascades that comprise sequential activation of several protein kinases and the ensuing phosphorylation of MAPKs,which activate transcription factors(TFs)to promote downstream defense responses.To identify plant TFs that regulate MAPKs,we investigated TF-defective mutants of Arabidopsis thaliana and identified MYB44 as an essential constituent of the PTI pathway.MYB44 confers resistance against the bacterial pathogen Pseudomonas syringae by cooperating with MPK3 and MPK6.Under PAMP treatment,MYB44 binds to the promoters of MPK3 and MPK6 to activate their expression,leading to phosphorylation of MPK3 and MPK6 proteins.In turn,phosphorylated MPK3 and MPK6 phosphorylate MYB44 in a functionally redundant manner,thus enabling MYB44 to activate MPK3 and MPK6 expression and further activate downstream defense responses.Activation of defense responses has also been attributed to activation of EIN2 transcription by MYB44,which has previously been shown to affect PAMP recognition and PTI development.AtMYB44 thus functions as an integral component of the PTI pathway by connecting transcriptional and posttranscriptional regulation of the MPK3/6 cascade. | Zuodong Wang Xiaoxu Li Xiaohui Yao Jinbiao Ma Kai Lu Yuyan An Zhimao Sun Qian Wang Miao Zhou Lina Qin Liyuan Zhang Shenshen Zou Lei Chen Congfeng Song Hansong Dong Meixiang Zhang Xiaochen Chen | 2023 | Plant Communications2023，4，6： | 0 |
