2012-3-7  Screening of 16 oilseed rape (Brassica napus L) genotypes for boron (B) boron toxicity tolerance was performed by growing plants in nutrient solutions. Plants were exposed to two levels of external B supply: 10 μM (control) and 1000 μM (toxic) for four weeks. Genotypic variation in plant growth and B accumulation was significant.

Discrimination of boron tolerance in Pisum ... - Plant

Boron (B) tolerance has been identified as a key target for field pea improvement. Screening for B tolerance in the field is problematic due to variability in space and time, and robust B molecular markers are currently unavailable in field pea. There has been recent progress in developing protocols that can accelerate the life cycle of plants to enable rapid generation turnover in single seed ...

Transport-coupled ubiquitination of the borate

Boron (B) is essential for plant growth and survival due to its function in cross-liking pectin at the rhamnogalacturonan II (RG-II; Yoshinari and Takano, 2017). Boron is taken up mainly as boric acid (B[OH] 3 ) by plant roots from the soil solution by passive diffusion and channels ( Funakawa and Miwa, 2015 ; Yoshinari and Takano, 2017 ).

Boron Toxicity and Tolerance in Plants: Recent

2016-1-1  2.1. Boron in the Cell Wall and Membranes. Ninety percent of B content in plant is localized in the cell wall fraction (Loomis and Durst, 1992, Blewins and Lukaszewski, 1998).Such evidence highlights the contribution of B in the organization of cell wall proteins, pectins, and/or precursors during plant growth and development (Hu and Brown, 1997). ...

IJMS Free Full-Text Boron Toxicity and Deficiency in ...

Boron is an essential plant micronutrient taken up via the roots mostly in the form of boric acid. Its important role in plant metabolism involves the stabilization of molecules with cis-diol groups. The element is involved in the cell wall and membrane structure and functioning; therefore, it participates in numerous ion, metabolite, and hormone transport reactions.

The mechanism of boron tolerance for maintenance

INTRODUCTION. Boron is an essential trace element for higher plants; however, when present at toxic concentrations it becomes a limitation for plant growth, leading to a subsequent reduction in crop yield (Cartwright, Zarcinas Spouncer 1986; Nable, Banuelos Paull 1997).Although the mechanism of B toxicity is still not clear, a primary phenotypic effect of B toxicity is a poorer root growth ...

Genotypic variation in plant response to low boron

Plant response to low B in the soil varies widely among species, and among genotypes within a species. Boron efficient genotypes are those that are able to grow well in soils in which other genotypes are adversely affected by B deficiency. This review considers the extent of variation in B efficiency in plant species and genotypes, the physiological nature of the efficiency mechanisms, what is ...
