| 1 | Photosynthesis, chilling acclimation and the response of antioxidant enzymes to chilling stress in mulberry seedlings显示文摘This study investigates the effects of cold-acclimation in conferring chilling tolerance in seedlings of the mulberry(Morus alba) variety ‘Qiuyu’. Changes in photosynthesis and antioxidant enzymes in chilling acclimatized(CA), and non-acclimatized(NA) seedlings were recorded during chilling stress(3 °C) and a recovery period(25 °C) each for 3 days. The results showed that CA plants had higher net photosynthetic rates(P_n), stomatal conductance(G_s), and maximum photochemical efficiency of photosystem Ⅱ(F_v/F_m) in response to chilling stress compared to NA. The seedlings maintained the same trends during the recovery stage. The responses of Q_A reduction degree (1-q_P) and prime electronic transfer rates(F_o) were lower in acclimatized than in non-acclimatized seedlings. Low-temperature acclimation and chilling stress also caused an increase in leaf proline and soluble sugar contents. Leaf malondialdehyde levels were significantly lower while ascorbate peroxidase(APX) activity was significantly higher in acclimatized seedlings, suggesting that elevated osmolytes and APX confer resistance to chilling temperatures. In this study on the response of mulberry seedlings to chilling stress, we also looked at the recovery process. The response to chilling determines whether mulberry leaves can survive under cold temperatures, while the recovery process determines whether photosynthesis can recover as soon as possible to avoid any secondary damage. | Xiaojia Liu Nan Xu Yining Wu Jinbo li Haixiu Zhong Huihui Zhang | 2019 | Journal of Forestry Research2019，30，6： | 5 |
| 2 | Changing Chinese Diets to Achieve a Win-Win Solution for Health and the Environment显示文摘Diets are key determinants of nutrition and health and play a significant role in the environment.In this article,we aim to(i)describe dietary transitions and health in China and the consequent environmental challenges;(ii)identify differences between current Chinese diets and healthy reference diets;(iii)conduct a systematic review assessing the health impacts of four reference diets on the Chinese population,and(iv)simulate changes in greenhouse gas emissions under different diet scenarios.The results show differences between the Chinese diets and reference diets,with the current Chinese diet including mainly grains(especially refined rice),excessive meat consumption,and insufficient consumption of fruit and milk.If all Chinese consumers adopt one of the healthy reference diets all the time,the incidence of diet-related chronic disease and mortality would be significantly reduced.Such dietary shifts would also reduce greenhouse gas emissions by 146-202 million tons(18-25 percent)compared with the projected emissions level in 2030. | Fangfang Sheng Jingjing Wang Kevin Z.Chen Shenggen Fan Haixiu Gao | 2021 | China & World Economy2021，29，6： | 2 |
| 3 | The genomes of medicinal skullcaps reveal the polyphyletic origins of clerodane diterpene biosynthesis in the family Lamiaceae显示文摘The presence of anticancer clerodane diterpenoids is a chemotaxonomic marker for the traditional Chinese medicinal plant Scutellaria barbata,although the molecular mechanisms behind clerodane biosynthesis are unknown.Here,we report a high-quality assembly of the 414.98 Mb genome of S.barbata into 13 pseudochromosomes.Using phylogenomic and biochemical data,we mapped the plastidial metabolism of kaurene(gibberellins),abietane,and clerodane diterpenes in three species of the family Lamiaceae(Scutellaria barbata,Scutellaria baicalensis,and Salvia splendens),facilitating the identification of genes involved in the biosynthesis of the clerodanes,kolavenol,and isokolavenol.We show that clerodane biosynthesis evolved through recruitment and neofunctionalization of genes from gibberellin and abietane metabolism.Despite the assumed monophyletic origin of clerodane biosynthesis,which is widespread in species of the Lamiaceae,our data show distinct evolutionary lineages and suggest polyphyletic origins of clerodane biosynthesis in the family Lamiaceae.Our study not only provides significant insights into the evolution of clerodane biosynthetic pathways in the mint family,Lamiaceae,but also will facilitate the production of anticancer clerodanes through future metabolic engineering efforts. | Haixiu Li Song Wu Ruoxi Lin Yiren Xiao Ana Luisa Malaco Morotti Ya Wang Meytal Galilee Haowen Qin Tao Huang Yong Zhao Xun Zhou Jun Yang Qing Zhao Angelos K.Kanellis Cathie Martin Evangelos C.Tatsis | 2023 | Molecular Plant2023，16，3： | 2 |

| 5 | Increase of nitrogen to promote growth of poplar seedlings and enhance photosynthesis under NaCl stress显示文摘The solution culture method was used to study the effect of increasing nitrogen on the growth and pho-tosynthesis of poplar seedlings under 100 mmol L-1 NaCl stress. I Increase in nitrogen reduced stomatal limitation of leaves under NaCl stress, improved utilization of CO2 by mesophyll cells, enhanced photosynthetic carbon assimi-lation capacity, significantly alleviated saline damage of NaCl, and promoted the accumulation of aboveground and root biomass. I Increased nitrogen enhanced photochemical efficiency (ΦPSⅡ) and electron transport rates, relieved the reduction of maximum photochemical efficiency (Fv/Fm) under NaCl, and reduced the degree of photoinhibition caused by NaCl stress. Increased nitrogen applications reduced the proportion of energy dissipating in the form of ineffective heat energy and hence a greater proportion of light energy absorbed by leaves was allocated to photo-chemical reactions. Under treatment with increased nitro-gen, the synergistic effect of heat dissipation and the xanthophyll cycle in the leaves effectively protected pho-tosynthetic PSⅡ and enhanced light energy utilization of leaves under NaCl stress. The increased nitrogen promoted photosynthetic electron supply and transport ability under NaCl stress evident in enhanced functioning of the oxygen-evolving complex on the electron donor side of PS Ⅱ. It increased the ability of the receptor pool to accept electrons on the PSII electron acceptor side and improved the sta-bility of thylakoid membranes under NaCl stress. Therefore, increasing nitrogen applications under NaCl stress can promote poplar growth by improving the effi-ciency of light energy utilization. | He Wang Huihui Zhang Yushu Liu Jinghong Long Liang Meng Nan Xu Jinbo Li Haixiu Zhong Yining Wu | 2019 | Journal of Forestry Research2019，30，4： | 0 |

| 7 | Diterpenoids from Scutellaria barbata induce tumour-selective cytotoxicity by taking the brakes off apoptosis显示文摘Medicinal plants are an excellent source of structurally diverse,bio-active compounds with potential in the fight against cancer.One of the most promising is Scutellaria barbata,prescribed traditionally for the treatment of cancers.Scutebarbatine A is the major diterpenoid,produced in specialized large,peltate trichomes on leaves of S.barbata.It induces dose-dependent apoptosis,specifically in cancer cells.The major class of proteins down-regulated are pro-survival proteins,the Inhibitors of Apoptosis(IAPs),and IAP regulating proteins.We propose that scutebarbatine A works by releasing the molecular brakes(the IAPs)on apoptosis in cell death-evading cancer cells.Comparison between the cytotoxicity of methanolic extracts of S.barbata leaves and decoctions(Ban Zhi Lian)prepared traditionally,showed substantially different chemical compositions and differential induction of apoptosis.Analyses suggest polyvalency between the constituents in both extracts,and ways to produce enhanced chemopreventive preparations for the treatment of cancer. | Matthew L.Tomlinson Man Zhao Elaine J.Barclay Jie Li Haixiu Li Juri Felix Lionel Hill Gerhard Saalbach Martin Rejzek Dongfeng Yang Qing Zhao Paul Kroon Wei Wang Yongping Bao Melanie-Jayne R.Howes Evangelos C.Tatsis Cathie Martin | 2022 | Medicinal Plant Biology2022，1，1： | 0 |
