Our study decouples the mechanisms of iron plaque and aerenchyma formation, revealing that these two processes, previously assumed to be mechanistically linked, are regulated independently by distinct hormonal pathways.Through a forward gen...

Plants fix carbon dioxide through photosynthesis, converting it into organic compounds. However, during photorespiration and lipid biosynthesis, significant amount the fixed carbon is released back into the atmosphere. To solve this ineffic...

A research team led by Dr. Kuo-Chen Yeh identified ENA1, a plasma membrane-localized transporter that mediates the root secretion of nicotianamine (NA) — a key metal chelator. This discovery uncovers a novel mechanism by which plants regula...

This work addresses a fundamental barrier in biomass production: the seasonal limitation of C4 grasses like Napier due to cold sensitivity. L2201 breaks through this constraint, extending productivity into cooler months, demonstrated by its...

In seeds, filial and maternal tissues are symplastically isolated. Nutrient delivery through plasma membrane-localized transporters at the junction of filial and maternal tissues is indispensable for sustaining endosperm and embryo developm...

The increasing use of indium in high-tech industries has inevitably caused its release into the environment. However, knowledge of its environmental fate has been very limited so far. Previously, we found that indium jeopardized phosphate u...

A mutant, non-response to fe-deficiency2 (nrf2) with defects on the response to Fe deficiency, was selected by a designed genetic screening. The corresponding gene NRF2 encodes a tetratricopeptide repeat (TPR) domain-containing protein and ...

Fe-deficiency induced transcriptional cascades controls Fe transport and utilization is important for plant to maintain homeostasis of this important element executing the biological function. So far, we know that many genes participating i...

The use of indium in semiconductor products has increased markedly in recent years. The release of indium into the ecosystem is inevitable. Under such circumstances, effective and accurate assessment of indium risk is important. An indispen...

Iron (Fe) is an essential element for all organisms. Fe deficiency-related health defects, especially anemia, is a big challenge to human health. In addition, imbalanced Fe homeostasis affects plants development and productivity in agricult...

Several studies elucidated the transcriptional responses to iron (Fe) starvation, however, the Fe sensing and signal transduction machineries are poorly resolved thus far in plants. With this focus, by using chemical biology approach, we id...

The manuscript describes the first thorough exploration of gallium exposure in the model plant Arabidopsis. Gallium, a rare element, is one of the major elements in semiconductor compounds that are used in integrated circuits and optoelectr...

Our manuscript describes a new approach for the identification of metal species using ESI-MS/MS through releasing the free metals from the corresponding metal-ligand complexes. The approach has potential for the accurate and simultaneous id...

Fe is essential for plant growth but toxic in excess. To acquire appropriate Fe, vascular plants have developed two unique strategies in sporophyte generation, the reduction-based Strategy I of non-graminaceous plants for Fe2+ and the chela...

In this study, we found that the zir1 mutant, defective in glutathione production, was found to be more sensitive to Fe deficiency than the wild type, and grew poorly in alkaline soil. Furthermore, the key genes involved in Fe uptake are ex...

Heavy metal hyperaccumulators grow endemically on metal-rich soils and exhibit extraordinarily high metal tolerance. Arabidopsis halleri, one of 500 found heavy metal hyperaccumulators in the world, is recognized as a zinc hyperaccumulator....

Fe nutrient and circadian period lengthThe daily biological rhythms of many organisms are regulated by a near 24-hour circadian clock. In plants, the central oscillator controls a range of important physiological output processes such as fl...

Iron is an essential micronutrient whose uptake is strictly regulated in plants. IRON-REGULATED TRANSPORTER 1 (IRT1) is the major transporter for ferrous Fe uptake in A. thaliana. In Fe homeostasis, constitutive turnover is one of the most ...

Under Fe deficiency, plant roots secrete specific compounds such as organic acids and phytosiderophores into the rhizosphere to increase Fe bioavailability by changing the soil pH or by binding to ferric Fe. Phytosiderophores are non-protei...

Many heavy metals are essential as trace nutrients for living organisms. These essential heavy metals can also cause toxicity at high levels. Plants have evolved a range of homeostasis mechanisms to minimize the harmful effects and maintain...
