The University of Geneva, Switzerland, has generated UV-resistant transgenic plants which produce high levels of antioxidants Plants have a love-hate relationship with sunlight. While some wavelengths are indispensable to them for performing photosynthesis, others, such as UV-B, are deleterious. Therefore, plants are equipped to detect these highly toxic rays and mount their defenses. A team led by Roman Ulm, Professor at the Faculty of Sciences at the University of Geneva (UNIGE),...

What Makes Plants Grow Toward The Light?
2013-05-28 14:02:26

Technische Universität München Plants have developed a number of strategies to capture the maximum amount of sunlight through their leaves. As we know from looking at plants on a windowsill, they grow toward the sunlight to be able to generate energy by photosynthesis. Now an international team of scientists has provided definitive insights into the driving force behind this movement — the plant hormone auxin. The growth of plants toward light is...

Space Station Crew Grow Plants Without Gravity

Lee Rannals for redOrbit.com — Your Universe Online An experiment reported in the journal BMC Plant Biology studied the effects of growing plants without gravity, helping to disprove one theory about how gravity kick-started plant behaviors on Earth. Astronauts growing Arabidopsis plants on the International Space Station tried to determine what plant growth patterns could be influenced by gravity. Plant roots exhibit characteristic behaviors called "waving" and...
