Original Source: Activation of phenylpropanoid pathway in legume plants exposed to heavy metals: Part I. Effects of cadmium and lead on phenylalanine ammonia-lyase gene expression, enzyme activity and lignin content.
Species-specific changes in expression of phenylalanine ammonia-lyase (PAL) and lignin content were detected in roots of soybean (Glycine max L.) and lupine (Lupinus luteus L.) seedlings treated with different concentrations of cadmium (Cd(2+), 0-25 mg/l) or lead (Pb(2+), 0-350 mg/l). The stimulatory effect of both metals was observed in mRNA coding for PAL in soybean. In the case of lupine, changes of PAL mRNA level were dependent on the metal used: Cd(2+) caused a decrease, whereas Pb(2+) an increase of P...

Extremely metal-poor gas at a redshift of 7
In typical astrophysical environments, the abundance of heavy elements ranges from 0.001 to 2 times the solar value. Lower abundances have been seen in selected stars in the Milky Way’s halo and in...
Jumping droplets help heat transfer
Many industrial plants depend on water vapor condensing on metal plates: In power plants, the resulting water is then returned to a boiler to be vaporized again; in desalination plants, it yields a s...

FDA Clamps Down on Metal-on-Metal Hips
WASHINGTON (MedPage Today) -- The FDA wants makers of metal-on-metal hip implants to prove that their products are safe if they want to continue to sell them.
FDA Proposes PMAs For Metal-On-Metal Hips
Spurred by heightened adverse event and revision rates in the past few years, FDA is proposing new PMA requirements for all metal-on-metal hip implants.

We examined changes in profiles of isoflavonoids in roots of lupine (Lupinus luteus L. cv. Juno) seedlings in response to treatment with two heavy metals: cadmium (at 10 mg/l) and lead (at 150 mg/l)....
Function of GRAS Proteins in Root Nodule Symbiosis Is Retained in Homologs of a Non-Legume, Rice.
Root nodule (RN) symbiosis in legumes shares genes involved in the early signaling pathway with more ancient arbuscular mycorrhiza (AM) symbiosis, which is widely spread in higher plants. The non-legu...
Heavy Metal Tolerance in Metal Hyperaccumulator Plant, Salvinia natans.
Metal tolerance capacity of Salvinia natans, a metal hyperaccumulator, was evaluated. Plants were exposed to 10, 30 and 50 mg L(-1) of Zn, Cd, Co, Cr, Fe, Cu, Pb, and Ni. Plant biomass, photosynthet...
