The pathway for producing ethylene

New research lays out the chemical steps used by a naturally occurring enzyme to convert a common chemical compound into ethylene—a plant hormone important for fruit ripening and an industrial chemical used in the production ...

How plant hormones control root growth

Plant roots can grow without limit. To do so, they need to balance the production of new cells via cell division and elongation. Plant hormones known as brassinosteroids play a key role in this balancing act. New work by ...

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 ...
