Other claims from this paper (6)
- Association Flavonoid extracts of HP32 alfalfa seedling roots contained a 60% higher concentration of compounds that induce nodABC transcription in Rhizobium meliloti than HP roots.
- Association HP32 alfalfa roots had a 77% higher concentration of luteolin than HP roots.
- Intervention effect Adding 10 micromolar luteolin to the rhizosphere of HP alfalfa seedlings increased nodulation, N(2) fixation and total N.
- Intervention effect Adding 10 micromolar luteolin to the rhizosphere of HP alfalfa seedlings increased total dry weight.
- Association Normal levels of flavone nodulation signals may limit root nodulation in HP alfalfa.
- Mechanism Genetic enhancement of specific biochemical signals is proposed as one mechanism for increasing alfalfa N(2) fixation.
