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
Phytophthora pathogens secrete an array of specific effector proteins to manipulate host innate immunity in order to promote pathogen colonization.However,little is known about the host targets of eff
Increasing CO2 concentrations([CO2]) have the potential to disrupt plant–pathogen interactions in natural and agricultural ecosystems,but the research in this area has often produced conflicting resul
番茄白粉病是一种真菌病害,能够造成番茄的减产和品质下降.研究者在野生番茄中发现了6 个单基因抗性基因(Ol)和3 个QTL.前期的番茄和白粉菌互作的研究中,采用cDNA-AFLP 的方法分析得到887 个差异表达片段,其中230 个DE-TDF 被测序,通过电子作图确定了抗病基因的候选序列.本文利用VIGS 方法,采用TRV2-LIC 载体,对抗病基因/QTL 的候选序列进行功能分析,以确定抗性反
