Iron uptake in plants is highly regulated in order to supply amounts sufficient for optimal
growth while preventing excess accumulation. In response to iron deficiency, plants induce …

Plants have developed sophisticated mechanisms to tightly control the acquisition and
distribution of copper and iron in response to environmental fluctuations. Recent studies with …

Iron (Fe) deficiency is a major abiotic stress in crop production. Although responses to Fe
deficiency in graminaceous plants, such as increased production and secretion of mugineic …

Iron is an essential and commonly limited nutrient for plants. To increase the uptake of iron
during times of low iron supply, plants, except the grasses, activate a set of physiological …

Networks of transcription factors control physiological, developmental and environmental
responses. Root iron acquisition responses are controlled by the essential bHLH protein FIT …

Iron is essential for most living organisms and is often the major limiting nutrient for normal
growth. Plants induce iron utilization systems under conditions of low iron availability, but the …

Our groups have previously identified in independent studies the gene At2g28160 as a
central transcription factor that is required for up-regulation of iron deficiency responses in …

In previous works using ethylene inhibitors and precursors, it has been shown that ethylene
participates in the regulation of several Fe deficiency stress responses by Strategy I plants …

Background Soluble sugars, which play a central role in plant structure and metabolism, are
also involved in the responses to a number of stresses, and act as metabolite signalling …

Long-distance signals generated in shoots are thought to be associated with the regulation
of iron uptake from roots; however, the signaling mechanism is still unknown. To elucidate …
