A kutatási téma leírása:
"The world population is expanding rapidly. According to the projections, The size of the land for food production must be doubled in the next two decades to meet the food demand of the growing world population. At least 60% of cultivated soils deficient in mineral nutrients, or contain toxic minerals, whereas about 50% of the world population suffers from micronutrient deficiencies. Iron seems to be one of the most important micronutrient in the soil, because it is essential both for plant productivity and for the quality of their products. Because the concentration of the iron is often low in the edible parts of the plant sources, the understanding of the physiological, biochemical, and molecular mechanisms of the transport and accumulation should contribute to the increase of it within the plant tissues. The understanding of all these processes would help to select and/or develop new genotypes through classical and molecular breeding are able to adopt to nutrient, mineral nutrient deficient conditions and allocating more micronutrients into the edible part of the plant. Iron homeostasis is an important determinant of photosynthetic efficiency in algae and higher plants, and the Fe limitation or excess highly affects the structure and function of the photosynthetic apparatus.
The understanding of leaf iron homeostasis and its regulation should contribute to achieve a higher iron accumulation in edible tissues, which may also make the edible parts a significant iron source for human consumption.
The topic covers (i) qPCR analysis of genes of several mesophyll cell iron transporters and iron homeostasis related transcription factors under different iron nutrition levels, (ii) tracking the incorporation of surplus iron (by Mössbauer spectroscopy, mesophyll cell fractionation, etc.) applied as foliar treatment or taken up by the roots into leaf iron depots, and (iii) genetic engineering (eg. inserting new GOIs, modifying the regulation, etc.) of plants, according to the findings of (i) and (ii).
