AB  - Monocots and dicots differ in their boron (B) requirement, but also in their capacity to accumulate silicon (Si). Although an ameliorative effect of Si on B toxicity has been reported in various crops, differences among monocots and dicots are not clear, in particular in light of their ability to retain B in the leaf apoplast. In hydroponic experiments under controlled conditions, we studied the role of Si in the compartmentation of B within the leaves of wheat (Triticum vulgare L.) as a model of a high-Si monocot and sunflower (Helianthus annuus L.) as a model of a low-Si dicot, with the focus on the leaf apoplast. The stable isotopes 10B and 11B were used to investigate the dynamics of cell wall B binding capacity. In both crops, the application of Si did not affect B concentration in the root, but significantly decreased the B concentration in the leaves. However, the application of Si differently influenced the binding capacity of the leaf apoplast for excess B in wheat and sunflower. In wheat, whose capacity to retain B in the leaf cell walls is lower than in sunflower, the continuous supply of Si is crucial for an enhancement of high B tolerance in the shoot. On the other hand, the supply of Si did not contribute significantly in the extension of the B binding sites in sunflower leaves.

AB  - Zinc (Zn) is an essential microelement for plants and also an important nutritional and health factor in humans. As a consequence of low Zn availability in soils, nearly half of the world's population suffers from Zn malnutrition. Zn deficiency has serious implications for human health (e.g. impairments in physical development, immune system, brain function and learning ability) and thus for the overall economy of a country; it is most severe in nations who depend on cereals as the main staple food. A critical Zn concentration in the whole grain for humans that depend on cereal based diets is 24 mg kg-1 dry matter. Research focused on increase of Zn content in cereals (biofortification), is the strategic priority in many countries. In Serbia however, the awareness of this problem is lacking, and no systematic survey of Zn availability in soi ls and concentrations
 in cereal grains has been undertaken so far.
Our study included 156 grain samples of the two major bread wheat varieties (Simonida and NS 40S) collected at 89 localities throughout Serbia. We analyzed soil pH, available Zn and grain Zn concentration together by principle component analysis and multiple linear regression. Wheat varieties did not differ in ability to accumulate Zn in grains. Both soil pH and available Zn concentration were the nominally significant predictors for grain Zn concentration and explained about 12 and 9% of the encountered variation, respectively. Zn concentration below the critical limit (24 mg kg-1) was found in 58% of grain samples (values in the range 11-61 mg kg-1, median only 21.3  mg kg-1), while in only 14% of soil samples the available Zn was below the critical value (05 mg kg-1).
The most severe lack of Zn in grains (below 18 mg kg-1) was observed in samples from the major production regions of bread wheat (e.g. Pancevo, Vrbas and Sremska Mitrovica). The alarming results of this survey indicate that Serbia urgently needs a strategy for Zn biofortification, primarily through a breeding program to enhance Zn efficiency as a sustainable alternative to application of Zn fertilizers.
