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 ...

Study pinpoints how Salmonella sneaks into plant roots

In recent years, contamination of salad vegetables by E. coli and salmonella bacteria—the most common causes of food poisoning—have led to large-scale recalls. Although most salmonella outbreaks are linked to contamination ...

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 ...

How plants harness microbes to get nutrients

A Rutgers-led team has discovered how plants harness microbes in soil to get nutrients, a process that could be exploited to boost crop growth, fight weeds and slash the use of polluting fertilizers and herbicides.

Groundwork for playing with the architecture of plants

Growing tomatoes at the same height so that they can be easily picked by a harvesting robot. Growing deeper roots where the soil is dry. These types of changes to plant architecture may well be enabled in the future thanks ...

New process in root development discovered

As the plant root grows, a root cap protects its fragile tip. Every few hours, the old cap is lost and a new one replaces it. This has puzzled scientists: How do cells at the tip know when to die, and how do cells further ...
