Open AccessKnockout of a gene encoding a Gγ protein boosts alkaline tolerance in cereal crops
Sorghum is highly tolerant to alkaline stress, but the underlying mechanisms are not well understood. Here, based on genotypic difference in alkaline tolerance of sorghum, it was found that AT1 (Alkaline toler...

Linking root morphology and anatomy with transporters for mineral element uptake in plants
One of the most important roles of plant roots is to take up mineral nutrients from soils for growth and development. The uptake of mineral nutrients is mediated by many different transporters expressed in the...

Role of qGZn9a in controlling grain zinc concentration in rice, Oryza sativa L.
A candidate gene responsible for higher grain zinc accumulation in rice was identified, which was probably associated with a partial defect in anther dehiscence.

Silicon accumulation in rice plant aboveground biomass affects leaf carbon quality
Silicon is known to be able to substitute carbon in plant biomass, especially in cellulose, lignin and phenols. However, a more comprehensive picture regarding the effect of silicon accumulation on plant carbo...

A member of cation diffusion facilitator family, MTP11, is required for manganese tolerance and high fertility in rice
Rice MTP11 is the trans-Golgi-localized transporter that is involved in Mn tolerance with MTP8.1, and it is required for normal fertility.

Silicon accumulated in the shoots results in down-regulation of phosphorus transporter gene expression and decrease of phosphorus uptake in rice
Silicon (Si) as a beneficial element can improve nutrient imbalance, but the molecular mechanism for this effect is poorly understood. The objective of this study is to examine the mechanism underlying Si-indu...

Transport System of Mineral Elements in Rice
Plant requires 14 mineral elements for their growth and development. These elements in the soil are taken up by the roots, translocated from the roots to the shoots, and distributed to different organs dependi...

Isolation and characterization of a rice line with high Cd accumulation for potential use in phytoremediation
To reduce cadmium (Cd) intake, remediation of Cd-contaminated soil and breeding crops with low Cd accumulation are important. This study aims to isolate rice mutants with altered accumulation of Cd.

Open AccessOsHKT1;4-mediated Na+ transport in stems contributes to Na+ exclusion from leaf blades of rice at the reproductive growth stage upon salt stress
Na+ exclusion from leaf blades is one of the key mechanisms for glycophytes to cope with salinity stress. Certain class I transporters of the high-affinity K+ transporter (HKT) family have been demonstrated to me...

Effect of in planta phosphorus on aluminum-induced inhibition of root elongation in wheat
Both aluminum (Al) toxicity and phosphorus (P) deficiency are limiting factors of crop production on acid soils. Although Al-P interaction has been extensively studied, the results are controversial. The aim o...

Molecular mechanisms of Al tolerance in gramineous plants
Aluminum (Al) toxicity has limited the productivity and expansion of cereal crops on acid soils; however, a number of plant species or cultivars have developed different strategies for detoxifying aluminum bot...

Magnesium transporters and their role in Al tolerance in plants
Magnesium (Mg) is an essential macronutrient for plant growth, which has diverse biological functions. However, little is known about the transport system of this nutrient in plants. In the genome of plants su...

Silicon enhances growth independent of silica deposition in a low-silica rice mutant, lsi1
To examine whether silica bodies are essential for silicon-enhanced growth of rice seedlings, we investigated the response of rice, Oryza sativa L., to silicon treatment. Silicic acid treatment markedly enhanced ...

Secretion time of phytosiderophore differs in two perennial grasses and is controlled by temperature
Some perennial grasses secrete phytosiderophores from the roots in response to Fe-deficiency. Here, we characterized the pattern of phytosiderophore secretion by Lolium perenne (cv. ‘Tove’) and Poa pratensis (cv....

Reexamination of silicon effects on rice growth and production under field conditions using a low silicon mutant
Silicon (Si) is a beneficial element for healthy growth and high and sustainable production of rice, but the mode of action of the beneficial effects has not been well understood. We carried out field trials f...

Secretion of malate and citrate from roots is related to high Al-resistance in Lespedeza bicolor
Lespedeza bicolor (Lespedeza bicolor Turcz. cv. Jiangxi) is a leguminous shrub that is well adapted to acid infertile soils. However, the mechanisms of aluminum resistance in this species...

Phytoremediation of Pb contaminated soil with polymer-coated EDTA
EDTA-assisted phytoextraction of lead (Pb) has been developed, but concerns have arisen due to the possibility of leaching of both Pb and EDTA to ground water caused by uncontrolled release. We developed five ...
