Molecular characterization of Fe-acquisition genes causing decreased Fe uptake and photosynthetic inefficiency in Fe-deficient sunflower

Geochemical Processes Constraining Iron Uptake in Strategy II Fe Acquisition

Phytosiderophores (PS) are natural chelating agents, exuded by graminaceous plants (grasses) for the purpose of Fe acquisition (Strategy II). They can form soluble Fe complexes with soil-Fe that can be readily taken up. PS are exuded in a diurnal pulse release, and with the start of PS release a "window of iron uptake" opens. In the present study we examined how this window is constrained in ti...

Molecular Cloning and Characterization of Fe-Superoxide Dismutase (Fe-SOD) from the Fern Ceratopteris thalictroides

Ferns are, evolutionarily, in a pivotal position between bryophytes and seed plants (Pryer et al., 2001). Fern gametophytes, like bryophytes, have no vascular system and live on substrate surfaces as small individual plants. However, fern sporophytes do have a vascular system enabling more vertical growth than the gametophytes, and resulting in a larger herbaceous plant form. The origins of pla...

Measurements and calculations of metastable level lifetimes in Fe X , Fe XI , Fe XII , Fe XIII , and Fe XIV

Lifetimes of metastable levels in the ground term of Fe ions within the 3s3p, k51 – 5, isoelectronic sequences have been measured. These measurements were performed utilizing ions that were selected by mass to charge ratio while transported from an electron cyclotron resonance ion source to a Kingdon ion trap, where they were captured and then confined for periods of up to 2.1 s. During this st...
