'Clay-pit to paradise' scheme

Article Abstract:

The plan for a $160 million initiative to create a series of eco-systems in a Cornwall china clay pit will soon be made public in London in an effort to obtain funding from the national Millennium Commission. Called the 'Eden Project,' this brain-child of Tim Smit is intended to provide scientists with a laboratory wherein they can study various natural phenomena such as the behavior of large groups of plants and the commercialization of crops from developing countries.

A ferric-chelate reductase for iron uptake from soils

Article Abstract:

Arabidopsis can acquire iron from soils of low iron availabiltiy, as ferric-chelate reductase activity increases when iron is deficient. The ferric-chelate reductase of plant roots is functionally similar to the human phagocytic NADPH oxidase gp91phox and yeast ferric-chelate reductases such as FRE1. The FRO2 gene expressed in iron-deficient rotes of Arabidopsis was isolated, and shown to be allelic to the frd1 mutations that impair ferric-chelate reductase activity.
