The glycosylation of nicotinate(NA),a key intermediate of the NAD salvage pathway,occurs widely in land plants.However,the physiological function of NA glycosylation is not well understood in planta,a
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
