Correlation between mineral nutrition and plant health
Project code: JKI-PB-08-0039
Contract period: 01.01.2008 - 31.12.2019
Purpose of research: Applied research
Currently the linkage between mineral nutrition and plant health is investigated for sulfur (S). The S metabolism delivers several possibilities to cope with biotic and abiotic stress. Generally the contents of primary and secondary S-containing compounds increase with increasing S supply. It was shown already in the mid of the nineties that the S nutritional status of agricultural crops is connected with the resistance of crops against fungal pathogen but still many questions are open regarding the mechanisms behind the so-called sulfur induced resistance. Plants which were infected with fungal pathogens react with the release of gaseous S compounds, with changes in the metabolism of glutathione and with the deposition of elemental S. It is the main target of the project to understand the mechanisms of the sulfur induced resistance enabling the scientists to develop fertilizer strategies to improve not only plant nutrition but also plant resistance against fungal pathogens.
