Title | Alternation of flavonoid accumulation under drought stress in Arabidopsis thaliana |
Description | We reported that flavonoids, a class of specialized metabolites, including flavonols and anthocyanins with strong radical scavenging activity contributed to the mitigation of oxidative and drought stress in Arabidopsis thaliana (Arabidopsis). However, the behavior of flavonoids during drought stress is still not well documented. Herein we investigated the time-series alternation of flavonoids in the aerial part of Arabidopsis (wild type, Col-0) during drought stress by LC-QTOF-MS. The drastic alternation of 5 flavonols and 5 anthocyanins was revealed together with changes in marker metabolites of drought stress, e.g., proline, raffinose, and galactinol. These findings indicate that flavonols and anthocyanins can mitigate drought stress. |

Title | Drought stress |
Description | Three-week-old plants vertically grown on GM plates were incubated in 24-well plates (TPP, http://www.tpp.ch/index.php). Each plant was put in a well with 3 ml water. Three-week-old plants were exposed to drought stress by stopping watering.The aerial samples were harvested at the time points of DAD 0, 3, and 5. |
Comment_of_details | DAD, days after drought. |
