    Evidence that AtMTP11 plays a role in the endogenous Mn 2+ tolerance of Arabidopsis comes from the insertional mutant mtp11 and RNAi transgenic lines that had reduced AtMTP11 expression . Assays for uptake of Mn 2+ into yeast cells were undertaken according to . DNA‐coated gold particles were pelleted by centrifugation, washed with .

  • Drought tolerance - Wikipedia

    Drought tolerance is the ability to which a plant maintains its biomass production during arid or drought conditions. Some plants are naturally adapted to dry conditions, surviving with protection mechanisms such as desiccation tolerance, detoxification, or repair of xylem embolism. Other plants, specifically crops like corn, wheat, and rice, have become increasingly tolerant to drought .
