“…Extractable boron by the three extractants (saturation extract, hot water, AB-DTPA) was significantly affected by the soil x B application rate interaction, which is in agreement with the findings of Al-Mustafa et al (1993). Extractable B levels were increased, in many cases significantly, as B application rate increased, regardless of the soil extractant.…”

“…The AB-DTPA test was used to screen soils contaminated with lead (Pb), cadmium (Cd), and Zn (Boon and Soltanpour, 1991), to assess molybdenum (Mo) availability in soils and mine spoils (Wang et al, 1994) and to monitor selected nutrients and heavy metals in a calcareous soil amended with solid waste (Hanlon et al, 1996). Also, Soltanpour (1984, 1987) and Al-Mustafa et al (1993) AB-DTPA to assess boron availability to alfalfa. The objective of this study was to test AB-DTPA extractable B for assessing B availability to wheat, using ten soils of Northern Greece.…”

The NH 4 HCO 3 -DTPA (AB-DTPA), 1 MNH 4 HCO 3 , 0.005 M DTPA, pH=7.6, was proposed as a multi-element extractant, for evaluating macro and micronutrients availability to plants. AB-DTPA was also evaluated as a soil test, for assessing boron availability and toxicity to alfalfa. In a pot experiment, ten soils of Northern Greece were used to assess AB-DTPA as an extractant of available boron to wheat (Triticum aestivum L., cv. Yecora), in comparison with hot water and saturation extract. Boron (B) was added as borax (Na 2 B 4 O 7 *10H 2 O) to the ten soils, at rates equal to 0, 3, and 5 mg B kg -1 . Wheat was grown in pots containing the boron amended soils to the stage of tillering, and dry aboveground biomass, B concentration and B uptake by wheat were determined. AB-DTPA extractable B was significantly greater than saturation extract and similar to hot water at each B application rate, and was correlated significantly with hot water (r=0.84), or with saturation extract (r=0.48). Extractable boron by all extractants, boron concentration in wheat and boron uptake were significantly affected by the soil x B application rate interaction. In assessing B availability to wheat using AB-DTPA as a soil 669 670 MATSI, ANTONIADIS, AND BARBAYIANNIS test, CEC should be included in the regression equation for B concentration, or pH for B uptake. However, the corresponding adjusted coefficients of determination for B concentration (adjusted R 2 =0.46) and B uptake (adjusted R 2 =0.48) were similar or lower to those of hot water (adjusted R 2 =0.45 and 0.60, respectively) and the saturation extract (adjusted R 2 =0.70 and 0.49, respectively), when the latter two soil tests were used in the regression equations without the inclusion of any soil property.

“…As we showed that excess borate can solubilise GIPCs from the detergent‐insoluble CL, we suggest a possible basis for the phytotoxicity of soils that have a high concentration of soluble B, which are prevalent in over‐irrigated semi‐arid areas (Al‐Mustafa et al ., ). Although a small amount of B appears to be required for the structural integrity of the membrane in plants, serving to cross‐link GIPCs to other membrane components (possibly glycoproteins), excess B may interfere with such cross‐linking.…”

Glycosylinositol phosphorylceramides from Rosa cell cultures are boron‐bridged in the plasma membrane and form complexes with rhamnogalacturonan II

Boron (B) is essential for plant cell-wall structure and membrane functions. Compared with its role in cross-linking the pectic domain rhamnogalacturonan II (RG-II), little information is known about the biological role of B in membranes. Here, we investigated the involvement of glycosylinositol phosphorylceramides (GIPCs), major components of lipid rafts, in the membrane requirement for B. Using thin-layer chromatography and mass spectrometry, we first characterized GIPCs from Rosa cell culture. The major GIPC has one hexose residue, one hexuronic acid residue, inositol phosphate, and a ceramide moiety with a C18 trihydroxylated mono-unsaturated long-chain base and a C24 monohydroxylated saturated fatty acid. Disrupting B bridging (by B starvation in vivo or by treatment with cold dilute HCl or with excess borate in vitro) enhanced the GIPCs’ extractability. As RG-II is the main B-binding site in plants, we investigated whether it could form a B-centred complex with GIPCs. Using high-voltage paper electrophoresis, we showed that addition of GIPCs decreased the electrophoretic mobility of radiolabelled RG-II, suggesting formation of a GIPC–B–RG-II complex. Last, using polyacrylamide gel electrophoresis, we showed that added GIPCs facilitate RG-II dimerization in vitro. We conclude that B plays a structural role in the plasma membrane. The disruption of membrane components by high borate may account for the phytotoxicity of excess B. Moreover, the in-vitro formation of a GIPC–B–RG-II complex gives the first molecular explanation of the wall–membrane attachment sites observed in vivo. Finally, our results suggest a role for GIPCs in the RG-II dimerization process.

“…The coloured hot water extracts in some soils may affect B determination. The HWE method has limitations for some soils and B extracted by this method did not correlate with crop responses under some management conditions (Gestring & Soltanpour, 1987;Offiah & Axley, 1988;Mustafa et al, 1993). The use of 0.05 M HCL has eliminated the problems of extraction with hot water.…”
