Open AccessGenetic background influences mineral accumulation in rice straw and grains under different soil pH conditions
Mineral element accumulation in plants is influenced by soil conditions and varietal factors. We investigated the dynamic accumulation of 12 elements in straw at the flowering stage and in grains at the mature...

Open AccessDiverse roles of the metal binding domains and transport mechanism of copper transporting P-type ATPases
Copper transporting P-type (P1B-1-) ATPases are essential for cellular homeostasis. Nonetheless, the E1-E1P-E2P-E2 states mechanism of P1B-1-ATPases remains poorly understood. In particular, the role of the intri...

Open AccessA silicon transporter gene required for healthy growth of rice on land
Silicon (Si) is the most abundant mineral element in the earth’s crust. Some plants actively accumulate Si as amorphous silica (phytoliths), which can protect plants from stresses. Here, we report a gene (SIET4) ...

Duplication of a manganese/cadmium transporter gene reduces cadmium accumulation in rice grain
Global contamination of soils with toxic cadmium (Cd) is a serious health threat. Here we found that a tandem duplication of a gene encoding a manganese/Cd transporter, OsNramp5, was responsible for low-Cd accumu...

Open AccessStructural basis for high selectivity of a rice silicon channel Lsi1
Silicon (Si), the most abundant mineral element in the earth’s crust, is taken up by plant roots in the form of silicic acid through Low silicon rice 1 (Lsi1). Lsi1 belongs to the Nodulin 26-like intrinsic pro...

Open AccessAcetic-acid-induced jasmonate signaling in root enhances drought avoidance in rice
Conferring drought resistant traits to crops is one of the major aims of current breeding programs in response to global climate changes. We previously showed that exogenous application of acetic acid to roots...

Breeding for low cadmium barley by introgression of a Sukkula-like transposable element
Barley is the fourth most produced cereal crop in the world and one of the major dietary sources of cadmium (Cd), which poses serious threats to human health. Here, we identify a gene that encodes a P-type hea...

Open AccessSecurity of a kind of quantum secret sharing with entangled states
We present a new collusion attack to a kind of quantum secret sharing schemes with entangled states. Using this attack, an unauthorized set of agents can gain access to the shared secret without the others’ co...

Erratum: Reducing phosphorus accumulation in rice grains with an impaired transporter in the node
Nature 541, 92–95 (2017); doi:10.1038/nature20610 In this Letter, owing to an error during the production process, the last column of Fig. 2b was labelled ‘PO4’ rather than ‘SO4’; this has been corrected online.

Open AccessDeployment of check-in nodes in complex networks
In many real complex networks such as the city road networks and highway networks, vehicles often have to pass through some specially functioned nodes to receive check-in like services such as gas supplement a...

Reducing phosphorus accumulation in rice grains with an impaired transporter in the node
The phosphorous transporter SPDT is identified in rice; depletion of the transporter gene alters the phosphorus distribution in rice grains and leaves, suggesting that the strategy could be used for agricultur...

Open AccessA heavy metal P-type ATPase OsHMA4 prevents copper accumulation in rice grain
Rice is a major source of calories and mineral nutrients for over half the world’s human population. However, little is known in rice about the genetic basis of variation in accumulation of copper (Cu), an ess...

Open AccessAtPHT4;4 is a chloroplast-localized ascorbate transporter in Arabidopsis
Ascorbate is an antioxidant and coenzyme for various metabolic reactions in vivo. In plant chloroplasts, high ascorbate levels are required to overcome photoinhibition caused by strong light. However, ascorbate i...

A node-based switch for preferential distribution of manganese in rice
Mineral nutrients, such as manganese, are required for the development of plants and their reproductive organs, but these can be toxic if accumulated at high concentrations. Therefore, plants must have a syste...

Open AccessAcquisition of aluminium tolerance by modification of a single gene in barley
Originating from the Fertile Crescent in the Middle East, barley has now been cultivated widely on different soil types including acid soils, where aluminium toxicity is a major limiting factor. Here we show t...

An efflux transporter of silicon in rice
Silicon plays a beneficial role in plant growth: it increases the resistance of plants to pests and diseases and helps minimize transpiration losses. Rice is a typical silicon-accumulating plant, able to build...

A silicon transporter in rice
Silicon, the second most abundant element in the Earth's crust and soil, is beneficial to plant growth and helps them overcome various forms of stress. It is particularly important for high and sustainable pro...

Detoxifying aluminium with buckwheat
Aluminium toxicity is a major problem limiting crop production in acid soils, which account for around 40% of the world's arable land1. Some plants have developed strategies to avoid or tolerate aluminium, includ...
