947 SCREENING MARIGOLD CULTIVARS FOR SUSCEPTIBILITY TO IRON TOXICITY

Individual susceptibility to toxicity.

Individual variation in susceptibility to chemical toxicity may be due to differences in toxicokinetic patterns or effect modification. Well-documented interspecies genetic differences in susceptibility to chemicals had lead to studies of such variation also within species. Epidemiological evidence now suggests that common variations, particularly in the P-450 enzymes, may play a major role in ...

Susceptibility to lead toxicity.

Adverse effects of lead on human health have been recognized for centuries. Nevertheless , current public health measures require a greater understanding of the pathobiology of chronic low level exposure (1-3). Such considerations are related to the question of what level of lead intake is harmful and why specific clinical manifestations of lead poisoning are encountered under particular circum...

Susceptibility of Cultivars to Biotic Stresses

Differential responses of two Iranian rice cultivars to arsenite toxicity

Arsenic (As) is a toxic metalloid which is usually found in rice fields as a contamination and has negative effects on the plant growth and reduces the crop yield. Similar to heavy metals, the deleterious effects of As may be due to, at least in part, the amount of absorbed As and disturbance of the plant water status. I...

Screening Soybean Cultivars for Resistance to Iron-Deficiency Chlorosis in Culture Solutions Containing Magnesium or Sodium Bicarbonate

Hydroponic culture solutions containing bicarbonate (HCO3 ) may be used to screen crops such as soybeans (Glycine max) for resistance to iron (Fe) deficiency or chlorosis. Some successful methods use sodium bicarbonate (NaHCO3) in combination with elevated partial pressures of carbon dioxide (CO2) to buffer pH and elevate bicarbonate. Replacing NaHCO3 with magnesium bicarbonate [Mg(HCO3)2] as t...
