化石记录是研究生物演化历程的直接证据,并且可以作为校正点与分子数据结合对生物类群进行谱系重建与年代估算。正确的评估和使用化石校正点是准确估算类群分歧时间之关键所在,同时也能够为理解和检验分子序列的进化速率模式(例如,Autocorrelated 或Independent)提供依据。

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
Legumes can host rhizobial bacteria and mycorrhizal fungi at the same time,which both improve salt tolerance of plants.The triple symbiosis could be good candidate for improving saline soil fertility.
许多细菌通过小分子信号监测自身群体密度进而调控群体生物学功能,这称为细菌的群体感应(Quorum Sensing,QS)现象.3-羰基辛酰基高丝氨酸内酯(N-3-oxo-octanoyl-homoserine lactone,3OC8-HSL)是革兰氏阴性细菌产生的群体感应信号分子,近年研究表明3OC8-HSL 能够被植物感知进而促进植物根的生长,但其调控植物根生长的分子机制还不清楚.通过药理学、

菘蓝(Isatis indigotica.Fort)是传统药材板蓝根(Isatidis Radix)的原植物.木脂素(lignan)类化合物是板蓝根中重要的一类抗病毒活性物质,由于其在菘蓝根部的累积的水平较低(＜1‰),因此研究其在菘蓝中的生物合成特征及调控机制对提高板蓝根药材中活性成分水平,改良药材品质具有重要意义.本研究以茉莉酸甲酯(Methyl jasmonate,MeJA)诱导的菘蓝毛状根
