The Accumulation of Heavy Metals in Hydrostemma Motleyi Hook. f. Mabberlay and Hydrilla verticillata Casp
Pengambilan logam berat (kuprum, zink, nikel, kadmium dan kromium) oleh Hydrostemma motleyi (Hook.f.) Mabberlay dan htydrilla verticillata Casp. telah dikaji. Umumnya pengambilan logam bertambah bila kepekatan logam bertambah. Faktor pertambahan yang menghubungkan paras logam dalam tubuhan dengan paras logam dalam iarutan ber&urang bila kepekatan logam bertambah. Tindakan antagonistik diperhati...
متن کاملThe molecular physiology of heavy metal transport in the Zn/Cd hyperaccumulator Thlaspi caerulescens.
An integrated molecular and physiological investigation of the fundamental mechanisms of heavy metal accumulation was conducted in Thlaspi caerulescens, a Zn/Cd-hyperaccumulating plant species. A heavy metal transporter cDNA, ZNT1, was cloned from T. caerulescens through functional complementation in yeast and was shown to mediate high-affinity Zn(2+) uptake as well as low-affinity Cd(2+) uptak...
متن کاملThe role of phytochelatins in constitutive and adaptive heavy metal tolerances in hyperaccumulator and non-hyperaccumulator metallophytes.
Using the gamma-glutamylcysteine synthetase inhibitor, L-buthionine-[S,R]-sulphoximine (BSO), the role for phytochelatins (PCs) was evaluated in Cu, Cd, Zn, As, Ni, and Co tolerance in non-metallicolous and metallicolous, hypertolerant populations of Silene vulgaris (Moench) Garcke, Thlaspi caerulescens J.&C. Presl., Holcus lanatus L., and Agrostis castellana Boiss. et Reuter. Based on plant-in...
متن کاملMulti-function Plant Defensin, Antimicrobial and Heavy Metal Adsorbent Peptide
Background: Defensin peptide isolated from plants are often heterogeneous in length, sequence and structure, but they are mostly small, cationic and amphipathic. Plant defensins exhibit broad-spectrum antibacterial and antifungal activities against Gram-positive and Gram-negative bacteria, fungi and etc. Plant defensins also play an important role in innate immunity, such as he...
متن کاملPlant Responses to Heavy Metal Toxicity
Plants, like all other organisms, have evolved different mechanisms to maintain physiological concentrations of essential metal ions and to minimize exposure to non-essential heavy metals. Some mechanisms are ubiquitous because they are also required for general metal homeostasis, and they minimize the damage caused by high concentrations of heavy metals in plants by detoxification, thereby con...
