Cadmium-induced sulfate uptake in maize roots.
The effect of cadmium (Cd) on high-affinity sulfate transport of maize (Zea mays) roots was studied and related to the changes in the levels of sulfate and nonprotein thiols during Cd-induced phytochelatin (PC) biosynthesis. Ten micromolar CdCl(2) in the nutrient solution induced a 100% increase in sulfate uptake by roots. This was not observed either for potassium or phosphate uptake, suggesti...
متن کاملHigh-throughput phenotyping technology for maize roots

Gr 1537-5110/$ e see front matter a 2011 IAgrE doi:10.1016/j.biosystemseng.2011.06.004 This paper describes the development of high-throughput measurement techniques allowing acquisition of phenotypical data describing maize roots. One of a maize root’s traits is the level of complexity, which was expressed in a Fractal Dimension ...
متن کاملLight-regulated gravitropism in seedling roots of maize.
Red light-induced changes in the gravitropism of roots of Zea mays variety Merit is a very low fluence response with a threshold of 10(-9) moles per square meter and is not reversible by far red light. Blue light also affects root gravitropism but the sensitivity of roots to blue is 50 to 100 times less than to an equal fluence of red. In Z. mays Merit we conclude that phytochrome is the sole...
متن کاملSimplified and representative bacterial community of maize roots.
Plant-associated microbes are important for the growth and health of their hosts. As a result of numerous prior studies, we know that host genotypes and abiotic factors influence the composition of plant microbiomes. However, the high complexity of these communities challenges detailed studies to define experimentally the mechanisms underlying the dynamics of community assembly and the benefici...
متن کاملUptake of rb and k by excised maize roots.
Radioactive isotopes are valuable tools for investigating the uptake and transport of ions by biological material. Their use as tracers provide results that often can be obtained only by such a technique. The reliability of isotopes as tracers, however, is sometimes implicitly accepted. Although the pitfalls are widely known, they are often ignored. The hazards were emphasized for us in the use...
