boron/シロイヌナズナ

bor1-1 (high boron requiring), an Arabidopsis thaliana mutant that requires a high level of B, was isolated. When the B concentration in the medium was reduced to 3 microM, the expansion of rosette leaves was severely affected in bor1-1 but not in wild-type plants. In a medium containing 30 microM B

Boron homeostasis is important for plants, as boron is essential but is toxic in excess. Under high boron conditions, the Arabidopsis thaliana borate transporter BOR1 is trafficked from the plasma membrane (PM) to the vacuole via the endocytic pathway for degradation to avoid excess boron transport.

Boron (B) deficiency affects the expressions of genes involved in major physiological processes. However, signal transduction pathway through which plants are able to sense and transmit B-deprivation signal to the nucleus is unknown. The aim of this work was to research in Arabidopsis thaliana roots

The development of Arabidopsis thaliana was dramatically altered within few hours following boron (B) deprivation. This effect was particularly evident in the apical root meristem. The essentiality of boron in plants has been clearly linked to its structural role in the cell wall, however the

Boron (B) is a micronutrient for plant development, and its deficiency alters many physiological processes. However, the current knowledge on how plants are able to sense the B-starvation signal is still very limited. Recently, it has been reported that B deprivation induces an increase in cytosolic

Aquaporins play essential roles in growth and development including stem elongation in plants. Tonoplast aquaporin AtTIP5;1 has been proposed to positively regulate hypocotyl elongation under high concentrations of boron (high-B) in Arabidopsis thaliana (L.) Heynh. However, the mechanism underlying

Boron (B) stress (deficiency and toxicity) is common in plants, but as the functions of this essential micronutrient are incompletely understood, so too are the effects of B stress. To investigate mechanisms underlying B stress, we examined protein profiles in leaves of Arabidopsis thaliana plants

Boron, an essential micronutrient, is transported in roots of Arabidopsis thaliana mainly by two different types of transporters, BORs and NIPs (nodulin26-like intrinsic proteins). Both are plasma membrane localized, but have distinct transport properties and patterns of cell type-specific

This work was aimed to evaluate the effect of boron (B) toxicity on oxidative damage level, non-enzymatic antioxidant accumulation such as anthocyanin, flavonoid and proline and expression levels of antioxidant enzymes including superoxide dismutase (SOD), ascorbate peroxidase (APX), catalase (CAT)

Nutrient deficiency in soil poses a widespread agricultural problem. Boron (B) is an essential micronutrient in plants, and its deficiency causes defects in both vegetative and reproductive growth in various crops in the field. In Arabidopsis thaliana, increased expression of a major borate

Soil fertilization is a common practice in modern agriculture, undertaken to prevent nutrient deficiency in crops. However, fertilization is costly and causes environmental pollution. The cultivation of plants that tolerate low nutrient supplies may circumvent this problem. Here, we report the

Boron (B) is essential for plants but toxic when present in excess. Arabidopsis thaliana BOR1 is a B exporter for xylem loading and is essential for efficient B translocation from roots to shoots under B limitation. B translocation to shoots was enhanced under B limitation in WT but not in bor1-1

Boron (B) is one of the essential nutrients for plant growth and reproduction. Transcriptome analyses have identified genes regulated by B deficiency, but their function mostly remains elusive. To identify the functions of B deficiency-inducible genes, T-DNA insertion mutants of 10 B

Boron (B) is an essential micronutrient of plants. In the present study, we characterized an Arabidopsis mutant lbt with significant low-boron tolerance that was identified based on our previous mapping of QTL for B efficiency in Arabidopsis. Multiple nutrient-deficiency analyses point out that lbt

Boron (B) is an essential micronutrient for higher plants. There is wide genetic variation in the response to B deficiency among plant species and cultivars. The objective of this study was to identify quantitative trait loci (QTL) that control B efficiency in natural Arabidopsis accessions. The B
