    Proteomic Analysis of High Temperature Stress-Responsive Proteins in Chrysanthemum Leaves

    Xin Li, Feiya Liao, Qiqi Ma, Beibei Jiang*, Yuanzhi Pan, Cheng Luo, Xinjie Wang, Aining Ran

    Phyton-International Journal of Experimental Botany, Vol.90, No.5, pp. 1415-1423, 2021, DOI:10.32604/phyton.2021.016143

    Abstract Chrysanthemum is one of the most important ornamental flowers in the world, and temperature has a significant influence on its field production. In the present study, differentially expressed proteins were investigated in the leaves of Dendranthema grandiflorum ‘Jinba’ under high temperature stress using label-free quantitative proteomics techniques. The expressed proteins were comparatively identified and analyzed. A total of 1,463 heat-related, differentially expressed proteins were successfully identified by Liquid Chromatography-tandem Mass Spectrometry (LC-MS/MS), and 1,463 heat-related, differentially expressed proteins were successfully identified by mass spectrometry after a high temperature treatment. Among these, 701 proteins were upregulated and… More >

    High temperature and water stress during flowering in tropical corn populations

    Rincón-Tuexi1, Sergio Castro-Nava2, José Alberto López-Santillán2, Alfredo J Huerta3, Carlos Trejo-López4, Florencio Briones-Encinia

    Phyton-International Journal of Experimental Botany, Vol.75, pp. 31-40, 2006, DOI:10.32604/phyton.2006.75.031

    Abstract Effects of water and high temperature stresses, either separately or in combination, over biomass accumulation, grain yield and its direct components grain number per ear and individual grain weight], as well as harvest index were determined in four tropical maize populations. Results indicated that water stress do not significantly affect the studied variables, due to the absence of a severe water stress during flowering. This was the result of the fallen precipitation at this time. The most important factor in this study was high temperature, which significantly reduced all studied variables, except individual grain weight.… More >
