Boron toxicity in rice (Oryza sativa L.). I. Quantitative trait locus (QTL) analysis of tolerance to boron toxicity.

Only registered users can translate articles

Boron toxicity tolerance of rice plants was studied. Modern japonica subspecies such as Koshihikari, Nipponbare, and Sasanishiki were tolerant, whereas indica subspecies such as Kasalath and IR36 were intolerant to excessive application of boron (B), even though their shoot B contents under B

Boron reduces cell wall aluminum content in rice (Oryza sativa) roots by decreasing H2O2 accumulation.

When boron (B) deficiency and aluminum (Al) toxicity co-exist in acidic soils, crop productivity is limited. In the current study, we found that 3 μM of B pretreatment significantly enhances rice root elongation under Al toxicity conditions. Pretreatment with B significantly decreases the deposition

Boron toxicity tolerance in barley through reduced expression of the multifunctional aquaporin HvNIP2;1.

Only registered users can translate articles

Boron (B) toxicity is a significant limitation to cereal crop production in a number of regions worldwide. Here we describe the cloning of a gene from barley (Hordeum vulgare), underlying the chromosome 6H B toxicity tolerance quantitative trait locus. It is the second B toxicity tolerance gene

Linking hydrogen-mediated boron toxicity tolerance with improvement of root elongation, water status and reactive oxygen species balance: a case study for rice.

Only registered users can translate articles

Boron is essential for plant growth but hazardous when present in excess. As the antioxidant properties of hydrogen gas (H2) were recently described in plants, oxidative stress induced by excess boron was investigated along with other biological responses during rice (Oryza sativa) seed germination

[Effect of Boron-antimony Interaction on the Uptake and Accumulation of Antimony and Boron by Rice Seedling].

Only registered users can translate articles

Effect of interactions between boron (B) and antimony on the uptake and accumulation by rice (Oryza sativa L.) seedling was investigated in solution culture. The results showed that Sb(III) and Sb(V) could inhibit rice growth and Sb(III) was more toxic than Sb(V). Concentrations of B in rice roots

[Effects of Boron Treatment on Arsenic Uptake and Efflux in Rice Seedlings].

Only registered users can translate articles

The impacts of boron (B) root application and foliar spray on arsenic (As) uptake, translocation, and efflux by/in rice seedlings (Oryza sativa L.) were investigated in three hydroponic experiments. The addition of B to culture medium did not alter concentrations of arsenite (As[Ⅲ]), arsenate

Suppression of a NAC-like transcription factor gene improves boron-toxicity tolerance in rice.

Only registered users can translate articles

We identified a gene responsible for tolerance to boron (B) toxicity in rice (Oryza sativa), named BORON EXCESS TOLERANT1. Using recombinant inbred lines derived from the B-toxicity-sensitive indica-ecotype cultivar IR36 and the tolerant japonica-ecotype cultivar Nekken 1, the region responsible for

OsNIP3;1, a rice boric acid channel, regulates boron distribution and is essential for growth under boron-deficient conditions.

Only registered users can translate articles

Boron is an essential micronutrient for higher plants. Boron deficiency is an important agricultural issue because it results in loss of yield quality and/or quantity in cereals and other crops. To understand boron transport mechanisms in cereals, we characterized OsNIP3;1, a member of the major

Dwarf and tiller-enhancing 1 regulates growth and development by influencing boron uptake in boron limited conditions in rice.

Only registered users can translate articles

Boron (B) is essential for plant growth, and B deficiency causes severe losses in crop yield. Here we isolated and characterized a rice (Oryza sativa L.) mutant named dwarf and tiller-enhancing 1 (dte1), which exhibits defects under low-B conditions, including retarded growth, increased number of

Genetic factors underlying boron toxicity tolerance in rice: genome-wide association study and transcriptomic analysis.

Only registered users can translate articles

Boron (B) toxicity is a nutritional disorder affecting crop production in many parts of the world. This study explored genetic factors associated with B tolerance in rice (Oryza sativa L.) through an integrated genome mapping and transcriptomic approach. Variation in B tolerance was first evaluated

Preferential Distribution of Boron to Developing Tissues Is Mediated by the Intrinsic Protein OsNIP3.

Only registered users can translate articles

Boron is especially required for the growth of meristem and reproductive organs, but the molecular mechanisms underlying the preferential distribution of B to these developing tissues are poorly understood. Here, we show evidence that a member of nodulin 26-like intrinsic protein (NIP), OsNIP3;1, is

Cell-type specificity of the expression of Os BOR1, a rice efflux boron transporter gene, is regulated in response to boron availability for efficient boron uptake and xylem loading.

Only registered users can translate articles

We describe a boron (B) transporter, Os BOR1, in rice (Oryza sativa). Os BOR1 is a plasma membrane-localized efflux transporter of B and is required for normal growth of rice plants under conditions of limited B supply (referred to as -B). Disruption of Os BOR1 reduced B uptake and xylem loading of

Strategies for successful isolation of a eukaryotic transporter.

Only registered users can translate articles

The isolation of integral membrane proteins for structural analysis remains challenging and this is particularly the case for eukaryotic membrane proteins. Here we describe our efforts to isolate OsBOR3, a boron transporter from Oryza sativa. OsBOR3 was expressed as both full length and a

Profiling the ionome of rice and its use in discriminating geographical origins at the regional scale, China.

Only registered users can translate articles

Element profile was investigated for their use to trace the geographical origin of rice (Oryza sativa L.) samples. The concentrations of 13 elements (calcium (Ca), potassium (K), magnesium (Mg), phosphorus (P), boron (B), manganese (Mn), iron (Fe), nickel (Ni), copper (Cu), arsenic (As), selenium

Micronutrient deficiencies in African soils and the human nutritional nexus: opportunities with staple crops.

Only registered users can translate articles

A synthesis of available agronomic datasets and peer-reviewed scientific literature was conducted to: (1) assess the status of micronutrients in sub-Saharan Africa (SSA) arable soils, (2) improve the understanding of the relations between soil quality/management and crop nutritional quality and (3)
