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 ...

How plants find their symbiotic partners

What would it be like to produce fertilizer in your own basement? Leguminous plants, like peas, beans and various species of clover, obtain the organic nitrogen they need for their growth from symbiotic soil bacteria via ...

A plant's way to its favorite food

Nitrogen is one the most essential nutrients for plants. Its availability in the soil plays a major role in plant growth and development, thereby affecting agricultural productivity. Scientists at the IST Austria were now ...

Ammonium triggers formation of lateral roots

Despite the importance of changes in root architecture to exploit local nutrient patches, mechanisms integrating external nutrient signals into the root developmental program remain poorly understood. "Here, we show for the ...

Agriculture: A climate villain? Maybe not!

The UN's Intergovernmental Panel on Climate Change (IPCC) claims that agriculture is one of the main sources of greenhouse gases, and is thus by many observers considered as a climate villain. This conclusion, however, is ...

Mechanism of jasmonate-promoted root hair growth in Arabidopsis

Root hairs are tubular polarized extensions of root epidermal cells and are crucial for plant anchorage, nutrient acquisition, and environmental interactions. The plant hormone jasmonate has been reported to promote root ...

How roots find their way to water

Plants use their roots to search for water. While the main root digs downwards, a large number of fine lateral roots explore the soil on all sides. As researchers from Nottingham, Heidelberg and Goethe University of Frankfurt ...

Specialized plant cells regain stem-cell features to heal wounds

If plants are injured, cells adjacent to the wound fill the gaps with their daughter cells. However, which cells divide to do the healing and how they manage to produce cells that match the cell type of the missing tissue ...
