| 4 | Intercropping with Solanum nigrum and Solanum photeinocarpum from Two Ecoclimatic Regions Promotes Growth and Reduces Cadmium Uptake of Eggplant Seedlings显示文摘Soil contamination by heavy metals is a serious environmental problem worldwide, and reduction of heavy metal accumulation in vegetables grown on contaminated land is a matter of urgency. A pot experiment was conducted to study the effects of intercropping with the Cd hyperaccumulators Solanum nigrum and Solanum photeinocarpum from two ecoclimatic regions, Ya'an and Chengdu,Sichuan Province, China, on the growth and cadmium(Cd) uptake of eggplant(Solanum melongena L.). The biomass, photosynthetic pigment contents, and activities of antioxidant enzymes of eggplant were enhanced by intercropping. The biomass of eggplant was the highest after intercropping with S. photeinocarpum from Ya'an, but did not differ significantly from that after intercropping with S. nigrum from Chengdu. The shoot Cd content of eggplant was significantly reduced by intercropping with the hyperaccumulators,which ranked as follows: S. nigrum from Chengdu > S. nigrum from Ya'an > S. photeinocarpum from Chengdu > S. photeinocarpum from Ya'an, with the decreases being 19.60%, 14.36%, 9.66%, and 6.42%, respectively, as compared with the control. The lowest shoot Cd content and translocation factor of eggplant were attained after intercropping with S. nigrum from Chengdu. Therefore, it was feasible to intercrop eggplant with S. nigrum and S. photeinocarpum on Cd-contaminated soil. | TANG Yi HE Juan YU Xuena XIE Yongdong LIN Lijin SUN Guochao LI Huanxiu LIAO Mingan LIANG Dong XIA Hui WANG Xun ZHANG Jing LIU Zejing TU Lihua LIU Li | 2017 | Pedosphere2017，27，3： | 17 |
| 5 | Increased resistance of drought by Trichoderma harzianum fungal treatment correlates with increased secondary metabolites and proline content显示文摘Plant secondary metabolites play vital role in plant stress response. In this study we investigated whether root colonization of tomato(Solanum lycopersicum) infected by Trichoderma harzianum leads to alterations in the biosynthesis of secondary plant metabolites including phytohormones and osmolyte proline under drought stress. Exposure of tomato to drought caused a drastic decline in plant growth and physiological parameters. Tomato inoculated with T. harzianum showed increased root and shoot growth and chlorophyll pigments as compared to uninoculated controls as well as drought stressed plants. Proline and total soluble protein content was increased in plants inoculated with T. harzianum under both normal as well as drought conditions. An obvious increase in phenol and flavonoid content was observed due to T. harzianum. In addition, T. harzianum inoculated plants maintained higher levels of growth regulators indole acetic acid, indole butyric acid, and gibberellic acid under drought stress. Improved secondary metabolites which play an important role in plant stress tolerance by T. harzianum may have coordinately worked for bringing the growth regulation by protecting membranes from reactive oxygen species(ROS) and enhance plant growth through accessing more nutrients by root system. | Mona S.Alwhibi Abeer Hashem Elsayed Fathi Abd_Allah Abdulaziz A.Alqarawi Dina Wafi K.Soliman Stephan Wirth Dilfuza Egamberdieva | 2017 | Journal of Integrative Agriculture2017，16，8： | 15 |

| 16 | 马铃薯晚疫病抗病基因研究进展显示文摘马铃薯晚疫病是马铃薯和番茄等茄科植物中最主要的病害之一,每年都引起巨大的经济损失。基因工程技术的发展为马铃薯晚疫病的防治工作提出了新的契机,从晚疫病抗性品种中筛选出具有高持久抗性的抗病基因,并将其转化到栽培品种中去,无疑是我们开发持久性晚疫病抗性的最快捷的手段。到目前为至,已经有十几个晚疫病抗性基因从S.demissum,S.bulbocastanum,S.berthaultii,S.mochiquense和S.pinnatisectum等抗性马铃薯品种中鉴定出来并已定位在马铃薯染色体基因组上,并有4个被克隆出来(R1,R3a,Rpi-blb1/RB和Rpi-blb2)。主要概述了马铃薯晚疫病抗病基因的研究现状和发展前景。 | 周军会 宋扬 张永强 | 2008 | 生物技术通报2008，24，5： | 5 |
| 17 | Hepatoprotective effect of Solatium xanthocarpum fruit extract against CCl_4 induced acute liver toxicity in experimental animals显示文摘Objective:To investigate the hepatoprotective potential of Solonum xanthocarpum(Solanaceae) (S.xanthocarpum) in experimental rats to validate its traditional claim.Methods:50%ethanolic fruit extract of S.xanthocarpum(SXE,100.200 or 400 mg/kg hods weight) was administered daily for 14davs in experimental animals.Liver injury was induced chemically,by CCl4 administration (1 mL/kg i.p.).The hepatoprotective activity was assessed using various biochemical parameters like aspartate aminotransferase(AST),alanine aminotransferase(ALT).Serum alkaline phosphatise (SALP) and total bilirubin.Meanwhile,in vivo antioxidant activities as lipid peroxidation(LPO), reduced glutathione(GSH).superoxide dismutase(SOD) and calalase(CAT) were screened along with histopathological studies.Results:Obtained results demonstrated that the treatment with SXE significantly(P<0.05- <0.001) and dose-dcpendcntly prevented chemically induced increase in serum levels of hepatic enzymes.Furthermore.SXE significantly(up to P<0.001) reduced the lipid peroxidation in the liver tissue and restored activities of defence antioxidant enzymes GSH,SOU and catalasc towards normal levels.Histopathology of the liver tissue showed that SXE attenuated the hepatocellular necrosis and led to reduction of inflammatory cells inflltration. Conclusions:The results of this study strongly indicate the protective effect of SXE against acute liver injun which may he attributed to its hepatoprotective activity,and there by scientifically support its traditional use. | Ramesh K Gupta Talib Hussain G.Panigrahi Avik Das Gireesh Narayan Singh K Sweety Md Faiyazuddin Chandana Venkateswara Rao | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，12： | 4 |
| 18 | 墨西哥野生马铃薯Solanum pinnatisectum抗晚疫病及抗马铃薯甲虫新基因的遗传分析与分子标记(英文)显示文摘马铃薯晚疫病(Phytophthora infestans)和科罗拉多马铃薯甲虫(CPB)是马铃薯生产中最为严重的病虫害。培育高抗晚疫病和甲虫的马铃薯品种是加拿大马铃薯育种工作的重要组成部分。目前,我们实验室在二倍体1EBN墨西哥野生种中已鉴定出抗马铃薯晚疫病和甲虫的新基因,并利用原生质体融合技术成功的将其转移到栽培品种中。但是,培育出抗晚疫病和抗甲虫的马铃薯新品种仍然是一项艰难而繁杂的工作。为了加快分离抗性基因,建立与抗性基因紧密关联的DNA分子标记至关重要。本研究以感病的二倍体马铃薯品种S.cardiophyllum作为父本,与带有抗性基因的墨西哥野生种S.pinnatisectum杂交。用叶片离体鉴定的方法测试F1和BC1代群体的抗病性,从而筛选抗晚疫病和抗甲虫的植株。US-8/A2交配型病菌测试显示所有的F1代植株都表现出抗晚疫病,而在BC1群体中抗病与感病植株的比例为1:1。这个结果证明,在墨西哥野生种S.pinnatisectum中存在一个抗晚疫病的单显性基因Rpi1。马铃薯甲虫抗性检测中,BC1群体的抗虫性分离比例为1:3.这表明其对甲虫的抗性是由多基因遗传控制的。在F1和BC1群体中利用分子标记结合集团分离分析法(BSA)对S.pinnatisectum中的晚疫病抗性基因Rpi1进行精细作图。根据马铃薯第7条染色体上RFLP标记TG20A和CP56之间的EST和STS标记的序列信息,合成了27对特异性PCR引物。获得一些与抗晚疫病基因Rpi1相关联的新的DNA标记。对BC1群体中大量的个体植株进行的分析表明,在马铃薯第7条染色体上位于抗晚疫病基因Rpi1两侧的两个标记S1c9和GP127-300,它们与Rpi1基因的遗传距离分别为1.17cM和3.89cM。这些标记被用来筛选两个细菌人工染色体(BAC)文库,并分离出与晚疫病抗性相关的90-125kb的BAC克隆,这些克隆将在后续的工作中通过图位克隆的方法而用于分离晚疫病抗性基因。同时分离与甲虫抗性紧密相关的分子标记的工作正在进行中。 | 陈勤 孙慧生 杨继良 李海燕 Sanjib Nandy Debbie Beasley 王冬冬 Mark Goettel | 2009 | 中国马铃薯2009，23，5： | 4 |
