In response to iron (Fe) deficiency, dicots employ a reduction-based mechanism by inducing
ferric-chelate reductase (FCR) at the root plasma membrane to enhance Fe uptake …

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 …

In response to Fe-deficiency, various dicots increase their root branching which contributes
to the enhancement of ferric-chelate reductase activity. Whether this Fe-deficiency-induced …

Previous studies have identified that auxins acts upstream of nitric oxide in regulating iron
deficiency responses in roots, but the upstream signaling molecule of auxins remains …

Iron is a critical cofactor for a number of metalloenzymes involved in respiration and
photosynthesis, but plants often suffer from iron deficiency due to limited supplies of soluble …

Fe deficiency (-Fe) is a common abiotic stress that affects the root development of plants.
Auxin and nitric oxide (NO) are key regulator of root growth under-Fe. However, the …

Iron is an essential element for life on Earth and its shortage, or excess, in the living
organism may lead to severe health disorders. Plants serve as the primary source of dietary …

The Arabidopsis FRO2 gene encodes the iron deficiency-inducible ferric chelate reductase
responsible for reduction of iron at the root surface; subsequent transport of iron across the …

In plants, the excess of several heavy metals mimics iron (Fe) deficiency-induced chlorosis,
indicating a disturbance in Fe homeostasis. To examine the level at which heavy metals …

Plants challenged with abiotic stress show enhanced polyamines levels. Here, we show that
the polyamine putrescine (Put) plays an important role to alleviate Fe deficiency. The adc2-1 …
