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 ...

Researchers advance in the development of 'papaya sugarcane'

When the papaya (Carica papaya) is ripening, its cell walls separate, making the tissue softer and more digestible. The cell contents become accessible and the sucrose in the fruit is more easily extracted. Sugarcane roots ...

Plant peptide helps roots to branch out in the right places

How do plants space out their roots? A Japanese research team has identified a peptide and its receptor that help lateral roots to grow with the right spacing. The findings were published on December 20, 2018 in the online ...

Plant root hairs form outward due to shank hardening

A group of international researchers has discovered how plant root hair grows straight and long. Many studies of root hair growth have been performed, but the molecular mechanism for the suppression of growth on the sides ...
