They've grown a lot on the ISS, one of the original objectives was to see if things are better nutritionally or grow faster in space. After a quick google:
Research Overview The Advanced Plant Experiment - Canadian Space Agency 2 (APEX-CSA2) provides insight into the fundamental processes by which plants produce cellulose and lignin, the two main structural materials found in plant matter. The experiment will be conducted using Canadian white spruce, Picea glauca. On Earth, various portions of a plant can have physically different compositions including different ratios of lignin and cellulose. This will affect the sensitivity of the plants to environmental conditions, to disease and infection and will have an influence on the type of industrial application plants can be used for. It is expected that growth of the trees for 30 days in microgravity will affect their growth rate, composition, tissue organization and gene expression. The results of this experiment will include improvement of the technology to grow trees in a spacecraft, enhancement of our understanding of tree physiology in the space environment and identification of genes related to specific plant characteristics. It is expected that these genes can be used as markers for plant selection in various Earth applications and to improve sustainability of the forest. This is the sort of thing they do, but they've have also sent some plants to the moon to act as a sort of canary in the coal mine, if they survive the cosmic rays we might. Maybe this cherry tree is has had a perfectly normal type of mutation like the four leafed clover? It just happened to be on the ISS at the time. Way beyond my meagre ken. ---In [email protected], <authfriend@...> wrote : What puzzles me a bit is that they've been taking seeds into space for a long time to see what happens to them. On the ISS, I think they even grow stuff. Have there been no other signs of accelerated maturation or other genetic mutation besides with the cherry trees? I haven't heard of any. The mysteries of nature. Could this be evolution caught in action? People have often speculated cosmic rays could have forced some of the huge leaps in life on Earth but I don't think anyone has ever documented it. Thing is, you wouldn't expect radiation to produce this much change in one go, normally radiational changes are destructive but who knows? Whereas most things get mutated too much and die, one gene in the right place gets zapped and two major differences occur. ---In [email protected], <authfriend@...> wrote : Tokyo (AFP) - A cosmic mystery is uniting monks and scientists in Japan after a cherry tree grown from a seed that orbited the Earth for eight months bloomed years earlier than expected -- and with very surprising flowers. The four-year-old sapling -- grown from a cherry stone that spent time aboard the International Space Station (ISS) -- burst into blossom on April 1, possibly a full six years ahead of Mother Nature's normal schedule. Its early blooming baffled Buddhist brothers at the ancient temple in central Japan where the tree is growing. "We are amazed to see how fast it has grown," Masahiro Kajita, chief priest at the Ganjoji temple in Gifu, told AFP by telephone. "A stone from the original tree had never sprouted before. We are very happy because it will succeed the old tree, which is said to be 1,250 years old." The wonder pip was among 265 harvested from the celebrated "Chujo-hime-seigan-zakura" tree, selected as part of a project to gather seeds from different kinds of cherry trees at 14 locations across Japan. The stones were sent to the ISS in November 2008 and came back to Earth in July the following year with Japanese astronaut Koichi Wakata, after circling the globe 4,100 times. Some were sent for laboratory tests, but most were ferried back to their places of origin, and a selection were planted at nurseries near the Ganjoji temple. By April this year, the "space cherry tree" had grown to around four metres (13 feet) tall, and suddenly produced nine flowers -- each with just five petals, compared with about 30 on flowers of the parent tree. It normally takes about 10 years for a cherry tree of the similar variety to bear its first buds. The Ganjoji temple sapling is not the only early-flowering space cherry tree. Of the 14 locations in which the pits were replanted, blossoms have been spotted at four places. Two years ago, a young tree bore 11 flowers in Hokuto, a mountain region 115 kilometres (70 miles) west of Tokyo, around two years after it was planted. It was of a variety that normally only comes into flower at the age of eight. Cosmic rays The seeds were sent to the ISS as part of "an educational and cultural project to let children gather the stones and learn how they grow into trees and live on after returning from space," said Miho Tomioka, a spokeswoman for the project's organiser, Japan Manned Space Systems (JAMSS). "We had expected the (Ganjoji) tree to blossom about 10 years after planting, when the children come of age," she added. Kaori Tomita-Yokotani, a researcher at the University of Tsukuba who took part in the project, told AFP she was stumped by the extra-terrestrial mystery. "We still cannot rule out the possibility that it has been somewhat influenced by its exposure to the space environment," she said.
