Climate change has a negative impact on food security. An international research team led by Wolfram Weckwerth from the University of Vienna has now conducted a study to investigate the natural variation of different chickpea genotypes and their resistance to drought stress. The scientists were able to show that chickpeas are a drought-resistant legume plant with a high protein content that can complement grain cultivation systems even in urban areas. The study was recently published in the specialist magazine The Plant Biotechnology.
Long periods of drought stress have also become a reality in Central Europe due to climate change, a major threat to plant productivity, harvests and therefore food security. At the same time, there is a decline in the use of plant genetic diversity, and the global food system has become more and more uniform. While there are approximately 7,000 edible crops, two-thirds of global food production is based on just nine crop species. "This narrow genetic base can have several negative consequences, such as increased susceptibility of plants to diseases and pests, reduced resistance to factors such as drought and climate change, and increased economic fragility," explains molecular biologist Wolfram Weckwerth from the University of Vienna. "Maintaining adequate plant and genetic diversity is crucial for agriculture, which must adapt to future changing conditions. With our new study, we have taken an important step in this direction and looked at the chickpea as an important food of the future," says Weckwerth.
