Plants have developed a number of strategies to capture the maximum amount of sunlight through their leaves.
American Journal of Botany Gravity affects the ecology and evolution of every living organism. In plants, the general response to gravity is well known: their roots respond positively, growing down, into the soil, and their stems respond negatively, growing upward, to reach the sunlight. But how do plants sense gravity and how do they direct or signal their cells to grow in response to it? Although botanists understand a great deal about how this works, a recent article in the recent issue...
Astronauts growing Arabidopsis plants on the International Space Station tried to determine what plant growth patterns could be influenced by gravity.
Researchers at Boston University have made discoveries that provide the foundation towards novel approaches to control insects that transmit deadly diseases such as dengue fever and malaria through their study of the Wolbachia bacteria.
Scientists have used chemical genomics to identify novel compounds that affect the ability of plants to alter their direction of growth in response to gravity, a phenomenon known as gravitropism. Combined with a plant's formidable genetic map, chemical genomics is becoming a powerful new tool in plant biology.
