Transporter protein regulates root gravitropism in Arabidopsis

In a finding that could be used to improve the nutrient uptake of crops, a RIKEN-led team has identified a transporter protein that is involved in the tendency of plant roots to grow downwards in response to gravity, a phenomenon ...

Time-lapse reveals the hidden dance of roots

Duke researchers have been studying something that happens too slowly for our eyes to see. A team in biologist Philip Benfey's lab wanted to see how plant roots burrow into the soil. So they set up a camera on rice seeds ...

Molecular compass for cell orientation

Plants have veins that transport nutrients throughout their whole body. These veins are organized in a highly ordered manner. The plant hormone auxin travels directionally from cell-to-cell and provides cells with positional ...

A molecular break for root growth

Roots are essential for reaching water and nutrients, for anchorage to the ground, but also for interacting and communicating with microorganisms in the soil. A long root enables the plant to reach deeper, more humid layers ...

Fish exposed to estrogen produce fewer males

Water tainted with even a small concentration of human hormones can have profound effects on fish, according to a University of Cincinnati biologist.

Mutant tomato helps to crack the secrets of fruiting

It may sound like something out of a science fiction B-movie, but with the help of a mutant tomato, researchers from Japan have discovered that the development process of fruit rewires their central metabolism pathway.

Strigolactones increase tolerance to weevils in tobacco plants

A team of researchers at the Max Planck Institute for Chemical Ecology in Jena, Germany, has discovered that strigolactones, a class of novel plant hormones, mediate the fine-tuning of the production plant defensive substances ...
