In Chile's arid Atacama, the driest desert in the world, scientists are studying a small, resilient flower that could hold genetic clues to help crops withstand worsening drought conditions driven by climate change. The Cistanthe longiscapa, known locally as "pata de guanaco," blooms during rare rainfall events in the Atacama desert, creating a mosaic of colors known as the flowering desert phenomenon.
Now a team at Chile's Andres Bello University is conducting genetic sequencing experiments to uncover the traits that allow the fuchsia-colored flower to survive water scarcity and extreme temperature swings in one of the planet's harshest environments. Their goal is to transfer drought-tolerant characteristics to other crops.
"With climate change, droughts are becoming a serious problem for agriculture, for the world and our country," said Ariel Orellana, director of the university's Plant Biotechnology Center. "We need plants that are capable of tolerating that drought."
Chile faces mounting water challenges and the World Resources Institute ranks it among the most water-stressed countries in the world. Studies warn of extreme drought conditions by 2050 across Chile's fertile central valley – key for agricultural exports including wine, fruit and livestock.
