Latest Gravitropism Stories
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...
Have you ever wondered why stems grow upwards and roots downwards?
On Earth all biology is subjected to gravity.
New research published by Cell Press in the June 15th issue of the journal Developmental Cell, reveals how plants modify their root architecture based on nutrient availability in the soil.
People arenâ€™t the only living things that suffer from stress.
Scientists have shown that the main shoot dominates a plantâ€™s growth principally because it was there first, rather than due to its position at the top of the plant.
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.
