| Popis: | The objective of the current study was to find out the effect of aluminum on the seedlings pre-treated by two levels of boron concentrations 4μM or 32μM grown in hydroponic solution of Al from 100-500μMAl for 3 days. Data revealed that Al had a negative effect on fresh, dry weight, water content, carbohydrate, protein and amino acids including proline constituents and changes in protein profile were analyzed of fourteen day-old Al-tolerant (‘Sakha 93’) cultivar of Triticum aestivum. The effect of boron treatment was pronounced at 32μM B level. Pretreatment of 4µM B and exposure to 500 µM Al revealed that insoluble protein increased soluble, total protein and total soluble sugars decreased in comparison to Al treatment only. Levels of amino acids most notably proline, the glutathione forming amino acids cysteine, glycine and glutamic and the branched chain amino acids (BCAAs) leucine, isoleucine and valine were increased under Al stress. The obtained results showed the high resistance of ‘Sakha 93’ cultivar to aluminum stress. Aluminum detoxification coincides with increased TSS, TP, Pro, BCAAs contents and polypeptides in the root to cope with alleviation of Al-stress; boron may have a role in this concern. |
