Structural and functional insights into the mechanism of action of plant borate transporters

Scientific Reports, 2021
Boron has essential roles in plant growth and development. BOR proteins are key in the active uptake and distribution of boron, and regulation of intracellular boron concentrations. However, their mechanism of action remains poorly studied.

Boron effectuation on barley (Hordeum vulgare) growth, metabolomics, protein profile, and antioxidant system during seedling growth stage [PDF]

Catrina: The International Journal of Environmental Sciences
Boron is an essential micronutrient that plays a critical role in plant growth, development, and metabolic regulation. Its optimal concentration range is narrow; both deficiency and toxicity can negatively impact crop performance.

Boron regulates mineralized tissue-associated proteins in osteoblasts (MC3T3-E1)

Journal of Trace Elements in Medicine and Biology, 2010
The aim of this study was to determine the effects of boron (B) on the cell-survival, proliferation, mineralization and mRNA expression of mineralized tissue-associated proteins. Additionally, determination of the effects of B on the BMP-4, -6 and -7 protein levels of pre-osteoblastic cells (MC3T3-E1) was also intended.

110GHz fT Silicon Bipolar Transistors Implemented using Fluorine Implantation for Boron Diffusion Suppression

, 2006
This paper investigates how fluorine implantation can be used to suppress boron diffusion in the base of a double polysilicon silicon bipolar transistor and hence deliver a record fT of 110 GHz.

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 [PDF]

The Plant Cell, 2007
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 B.

High levels of boron promote anchorage-independent growth of nontumorigenic cells [PDF]

, 2020
WHO has presented a health-based guideline value for boron in drinking water. That fact indicates that a high level of boron is toxic for humans. However, there is no direct evidence of boron-mediated malignant transformation.

The Boron & De Weer Model of Intracellular pH Regulation

Physiome, 2020
The classic Boron & De Weer (1976) paper provided the first evidence of active regulation of pH} in cells by an energy-dependent acid-base transporter. These authors also developed a quantitative model --- comprising passive fluxes of acid-base equivalents across the cell membrane, intracellular reactions, and an active transport mechanism in the ...

Boron uptake in rice is regulated post-translationally via a clathrin-independent pathway

Plant Physiology, 2021
Abstract Uptake of boron (B) in rice (Oryza sativa) is mediated by the Low silicon rice 1 (OsLsi1) channel, belonging to the NOD26-like intrinsic protein III subgroup, and the efflux transporter B transporter 1 (OsBOR1). However, it is unknown how these transporters cooperate for B uptake and how they are regulated in response to B ...
