Investigating key regulators of nitrogen demand signalling and symbiotic nitrogen fixation in Medicago truncatula
Nitrogen (N) is an essential nutrient required for plant growth and represents a primary limiting factor in determining crop yield. To overcome N limitation, legumes form mutualistic relationship with N-fixing bacteria resulting in the formation of root nodules, where symbiotic N-fixation (SNF) …

Identifying genes related to symbiotic nitrogen fixation in Medicago truncatula Tnt1 insertion mutants using a forward genetics approach
Nitrogen is an essential nutrient required by all plants. Although the earth’s atmosphere consists of approximately 78% nitrogen, it exists in an unusable form for plants. Current agricultural practices rely on industrial nitrogen fixation to produce fertilizers that improve crop productivity. …

Dissecting the NCR Peptide Landscape in the R108 Ecotype in Medicago Truncatula and the Search for the NF21325 Symbiotic Mutant
Leguminous plants utilize Symbiotic Nitrogen Fixation (SNF) within root nodules to convert atmospheric nitrogen into bioavailable ammonium. In Medicago truncatula, nearly 700 Nodule-specific Cysteine-Rich (NCR) peptides regulate this process. This study investigates the R108 mutant line NF21325, …

Monitoring the influx of marine derived Nitrogen and characterizing soil food webs of riparian zones of the Elwha River Watershed, WA, USA.
<p>Nitrogen is often the most limiting nutrient to productivity in terrestrial ecosystems, and can have large effects on ecosystem processes. Two sources of nitrogen to Pacific Northwest riparian areas are marine derived nitrogen (MDN) via anadromous pacific salmon and symbiotic nitrogen fixation …

The ecology and nitrogen-fixing ability of selected Aspalathus spp. in fynbos ecosystems
… the role that this genus may play in the nitrogen economy and ecology of fynbos ecosystems. From the literature it is argued that fire plays a pivotal role in these ecosystems as decomposition is very slow. Decomposition returns nutrients trapped in the vegetation back to the soil. …

Functional genomics of nodulins in the model legume Lotus japonicus
… conditions for screening transformants for symbiotic phenotypes were improved. These platforms enable us to identify genes, validate their expression and functionally characterise them in the minimum of time. The resources that I helped to establish, were used in collaboration with other …

EVALUATION OF SEED TREATMENTS ON THE NODULE COMPETENCY OF SOYBEAN INOCULANTS
Soybean has a strong demand for nitrogen that can be acquired from atmosphere for vegetative growth and seed production through the symbiosis with the soil bacterium Bradyrhizobium japonicum (B. japonicum). However, the native soil bradyrhizobia may be ineffective in nitrogen fixation and the …
