摘要

摘要铁作为人体必需的微量元素，是大多数生物体必需的微量营养素。白扁豆（C.blinii）是一种生长在中国四川的中药材。我们选择C.blinii作为材料来探索植物对铁的反应方式。我们的结果表明，铁增加了C.blinii中内源生长素的含量、腺毛密度和特征二萜blinin的含量。通过RNA测序，blinin合成途径（MEP）中的大多数关键酶在铁作用下上调。CbHO-1（血红素加氧酶基因）在外源IAA处理下上调。总之，这些结果表明，C.blinii通过生长素-萜类代谢对铁产生反应，这一过程可能与CbHO-1有关。

Conyza blinii responds to the changes of exogenous iron through auxin-terpenoids metabolism pathway

ABSTRACT As an essential trace element, iron is a necessary micronutrient for most organisms. Conyza blinii (C. blinii) is a traditional Chinese medicine grown in Sichuan, China. We chose C. blinii as material to explore the way plants respond to iron. Our results showed that iron increased the content of endogenous auxin, glandular trichomes (GTs) density and the content of blinin, the characteristic diterpene in C. blinii. Most of the key enzymes in the blinin synthesis pathway (MEP) were upregulated under iron by RNA sequencing. CbHO-1 (Heme oxygenase gene) was upregulated under exogenous IAA treatment. Taken together, these results suggest that C. blinii respond to iron through auxin- terpenoids metabolism, and this process may be related to CbHO-1.
