菠萝如何帮助农作物使用更少的水吗

The pineapple is the second most grown fruit crop behind bananas, with 85 countries producing about 25 million metric tons each year。 It’;s sweet, exotic, tasty。 Most people love it。 But there’;s more to the pineapple than meets the eye。 It’;s one of the most drought resistant crops out there, and scientists have now finally identified the genes that make the pineapple so resilient。 By genetically engineering similar crops that share a genetic history with the pineapple it’;s possible to lend its drought resistance, and thus help curb the stress these face at the hand of global warming

Although largely everyone in the world largely refers to the fruit as “;ananas”;, the first English speaking settlers called it the pineapple due to its resemblance with a pine cone。 Christopher Columbus brought this native of South America back to Europe as one of the exotic prizes of the New World。 It’;s thought, however, that the pineapple was first domesticated about 6,000 years ago in what is now southwest Brazil and eastern Paraguay。

Like most plants, the ancestors of the pineapple went though various genome doubling。 Tracking the remnants of these genome duplications proved to be the scope of the researchers at the University of Illinois。 The team sequenced the entire genome of the pineapple, along with certain grasses, and found evidence of two whole-genome duplications in the tropical fruit’;s history。 The sequencing also validated previous findings of three such duplications in grasses。 The most important findings have to do with how the pineapple performs photosynthesis。
