Endogenous indole-3-acetic acid (IAA) was found in axenically cultured gametophytes of the leafy liverwort, Plagiochila arctica Bryhn and Kaal., by high-performance liquid chromatography with electrochemical detection. Identification of the methylated auxin was confirmed by gas chromatography-mass spectrometry. Addition of 57 micromolar IAA to cultures increased relative production of ethylene. This is the first definitive (gas chromatography-mass spectrometry) demonstration of the natural occurrence of IAA in a bryophyte.
通过高效液相色谱-电化学检测法,在无菌培养的北极叶苔(Plagiochila arctica Bryhn and Kaal.)配子体中发现了内源性吲哚-3-乙酸(IAA)。通过气相色谱-质谱法确认了甲基化生长素的鉴定。向培养物中添加57微摩尔IAA可增加乙烯的相对产量。这是首次在苔藓植物中明确(气相色谱-质谱法)证明IAA的天然存在。
