Abnormal zinc amounts, mostly due to human activities, can be toxic to flora, fauna, and humans. In plants, excess zinc causes morphological, biochemical, and physiological disorders. Some plants have the ability to resist and even accumulate zinc in their tissues. To date, 28 plant species have been described as zinc hyperaccumulators. These plants display several morphological, physiological, and biochemical adaptations resulting from the activation of molecular Zn hyperaccumulation mechanisms. These adaptations can be varied between species and within populations. In this review, we describe the physiological and biochemical as well as molecular mechanisms involved in zinc hyperaccumulation in plants. specialized zinc hyperaccumulation bioavailability tolerance molecular mechanisms plants 076 020 9 5 art. 562 [22 p.] 2020 https://www.documentation.ird.fr/hor/fdi:010079305 10.3390/plants9050562 [F B010079305] https://www.documentation.ird.fr/hor/fdi:010079305 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers20-07/010079305.pdf IRD - Base Horizon / Pleins textes 2020-07-31 2020-07-31 fdi:010079305 fre
