Genetic variability in sunflowers could revolutionize phytoremediation technology.
The researchers studied the levels of different microelements in wild sunflower species and hybrids to understand their genetic differences in nutrient absorption. They analyzed essential and non-essential micronutrients in various sunflower plants. The results showed that hybrids had higher levels of manganese compared to wild species. Iron, boron, and manganese were the most concentrated elements in all plants. The variation in microelement levels depended on the specific plant type and element. Wild species showed a wider range of variation compared to hybrids. This genetic variability suggests that different sunflower plants react differently to microelement deficiencies or excesses. This information could be useful for breeding sunflowers with improved tolerance and ability to accumulate microelements, which could benefit phytoremediation efforts to clean up soil contaminated with these elements.
