It can absorb and store salt within its cells and thrives even in seawater, withstanding up to 600 millimolar salinity, the scientific measure of chemical concentration in liquids.” — can also endure lithium, chromium, boron and magnesium, which makes it capable of growing in soils that are toxic to most plants, emerging as a prime candidate for space agriculture.
There was an eight-day growth period during which the samples grew their first leaves and formed roots, exceeding expectations on how well the plant would perform, she adds.samples and preserved them in a fixative solution that froze the plant's tissue and genome at minus 80 degrees Celsius for the journey back. The samples made it to Ege University on February 29.
“In terrestrial conditions, when a seed germinates, it moves its roots in the direction of gravity and its stems towards a light source. But this drastically changes in microgravity because the sense of direction by gravity is lost,” Ozgur Uzilday explains. What remains after that is the chemical composition of regoliths. Not only can regoliths be toxic, it is also virtually impossible for the plants we consume to survive in these environments due to the absence of organic matter.Referring to the plant’s ability to absorb unwanted substances such as salt, chromium and aluminium, she adds that the plants could then “be harvested and burned, eliminating these substances from the regolith.
