  • Iron in plants and soil

    EnvironmentResourcesCausesSymptomsPreventionTreatmentDiagnosisRisksIron is the fourth most abundant element found in soil though it is largely present in forms that cannot be taken up by plants. Iron, in small amounts, is essential for healthy plant growth and is classed as a micronutrient. It is important for the development and function of chlorophyll and a range of enzymes and proteins. It also plays a role in respiration, nitrogen fixation, energy transfer and metabolism. As with other nutrients, plants can have too much iron but this primarily affects the uptake of other nutrients rather th

    Regulation of iron uptake is critical for plant survival. Although the activities responsible for reduction and transport of iron at the plant root surface have been described, the genes controlling these activities are largely unknown. We report the identification of the essential gene Fe-deficiency Induced Transcription Factor 1 ( FIT1 ), which encodes a putative transcription factor that

  • Mitochondrial iron transport and homeostasis in plants

    Sep 06, 2013· Although iron is generally quite abundant in the soil, it has a low bioavaiility in aerobic environments at neutral to basic pH and as a result, approximately 30% of the world’s soils are considered iron-limiting for plant growth. Iron deficiency represents an enormous problem in human populations as well, with approximately two billion
