Optimal distribution of NO3-in plant tissues is an important prerequisite for improving NO3-metabolism and increasing nitrogen use efficiency(NUE).In order to test the hypothesis that long transport o
Because of its significant impact on plant growth and development,CO2 enrichment has already appeared as a cutting-edge issue in global ecology and plant physiology research.Although the effect of CO2
氮素是植物所必需的大量元素,直接影响的植物生长发育.研究植物对氮素的响应及吸收利用规律,对于提高作物的氮素利用率、减少环境污染具有重要意义.但目前对氮素调控的分子机制的研究还不够深入.本研究找到一个新的突变体,在受硝酸诱导后,其响应硝态氮的信号明显比野生型弱.利用图位克隆的方法克隆出了突变基因,并将该基因命名为NSRG1.在nsrg1 突变体中受硝酸诱导基因的诱导量显著低于野生型,表明NSRG1
Iron(Fe) is an indispensable micronutrient for plant growth and development.The regulation of Fe homeostasis in plants is complex and involves a number of transcription factors.
Triterpenes in Betula Platyphlla suk.have vital activities of anti-HIV and anti-tumor,and the active components of white birch triterpenes(betulin,oleanolic acid,damareneglycol)and the sterol came fro
Betula platyphylla is a rich repository of pharmacologically active secondary metabolites known as birch triterpenoids(TBP).Here,we cloned the squalene synthase(SS)and squalene epoxidase genetic(SE)se
广藿香是唇形科多年生草本植物。广藿香精油特异地由约24 种倍半萜组成,广泛用于食品、日化香精及医药行业,具有重要经济价值,其中广藿香醇约占35％,是其重要组分。广藿香叶片表面具有非腺毛、头状腺毛和盾状腺毛三类表皮毛,精油主要储存在盾状腺毛中,但目前对腺毛发育的研究匮乏。我们在研究植物年龄因子——miR156 调控广藿香醇合成的过程中发现,广藿香叶片上腺毛的数目亦随植物年龄增长而增加,暗示年龄因子参
Plastic glutamine synthetase(GS2)is a key enzyme responsible for the first step of ammonium assimilation.Although GS2 function has been studied in some diploid species,much less is known about TaGS2 g
Plants have evolved to express some members of the nitrate transporter 1/peptide transporter family(NPF) to uptake and transport nitrate.However,little is known of the physiological and functional rol
Plant viruses move from cell to cell through plasmodesmata to spread infection.The endoplasmic reticulum(ER),a core structural component of plasmodesmata,was postulated to form a platform for the inte
