In higher plants, the shoot and the root generally show negative and positive gravitropism, respectively. To elucidate the molecular mechanisms involved in gravitropism, we have isolated many shoot ...

A novel, three-dimensional recording, vibrating probe was used for measuring the density and direction of the endogenous ionic current of cress roots (Lepidium sativum L.) bathed in low salt media ...

Germinating seedlings know which way is up. Perhaps they just know which way is down. They can not see, hear, taste, smell or feel anything like we can. Nonetheless, they know which direction to ...

Highly developed seed plants evolved deep root systems that are able to sense Earth's gravity. The 'how and when' of this evolutionary step has, until now, remained unknown. Plant biologists have ...

When a germinating seed is laid on its side, some roots promptly bend earthward, while others turn more slowly. Directed growth of plant roots toward gravity is critical to ensure the availability of ...

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 ...

What happens belowground in a corn field is easy to overlook, but corn root architecture can play an important role in water and nutrient acquisition, affecting drought tolerance, water use efficiency ...

Aug. 2 (UPI) --To make the transition from sea to land, plant roots had to learn to grow downward, to follow gravity. This ability, gravitropism, helped plants anchor to the soil and retrieve water ...

Plants are able to respond to their environment and changes in conditions. In the phototropism phenomenon, for example, plant parts will turn towards the sun. And gravitropism refers to the ability of ...

One of the most important events in evolutionary history occurred around 500 million years ago with the spread of plant life from water to land. For plants to thrive in this new environment, root ...
