Latest Plant Cells Stories
Biologists at UC San Diego have solved a long-standing mystery concerning the way plants reduce the numbers of their breathing pores in response to rising carbon dioxide levels in the atmosphere.
From far away, the top of a leaf looks like one seamless surface; however, up close, that smooth exterior is actually made up of a patchwork of cells in a variety of shapes and sizes.
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...
As large organisms, trees face some remarkable challenges, particularly regarding long-distance transport and communication.
New research by UCLA life scientists could lead to predictions of which plant species will escape extinction from climate change.
The way in which plants space out the pores through which they breathe depends on keeping a protein active during stem cell growth.
