Galls can be distinguished from beneficial nitrogen fixing bacterial nodules by breaking open the structure ... incognita resistant or tolerant varieties in infested fields whenever possible. Plant ...

Root-knot nematodes (RKN, Meloidogynespp.) are microscopic roundworms that feed on plant roots. M. incognita, the Southern root-knot nematode, is the most common RKN species in the region. Once RKN ...

Bacteria inside root nodules need oxygen to survive. A pink or red color inside a nodule indicates the oxygen supply is robust and the bacteria are thriving. Disclaimer: AAAS and EurekAlert!

A genetic “off switch” that shuts down nitrogen fixation when soil nitrate levels are high has been identified by a global ...

We are exploring how these nitrogen-fixing root nodules evolved in only legumes in the first place ... Higher yields would create new opportunities for small-scale and subsistence farmers to grow and ...

This rhythmic gene expression influences the regions of the root susceptible to rhizobial infection and the distribution of ...

This gave the concrete the right level of porosity to wick water and nutrients through it and allow plant roots to spread. Researchers tested the growth of tomatoes, radishes, and romaine lettuce ...

I’ve just found out that plants have three important parts. The roots, the stem and the leaves. Some plants also have flowers which are made up of petals. The roots keep the plant in the ground ...

Yet Gagliano insists she’s not using metaphor. Language is important to Gagliano. She's a plant scientist making bold claims about plant consciousness and intelligence based on experiments and ...

Kathy Willis considers our changing relationship with plants over the last 250 years - from tools to exploit, to objects of beauty, to being an essential resource we must conserve.
