Nitrogen nutrition effects on δ13C of plant respired CO2 are mostly caused by concurrent changes in organic acid utilisation and remobilisation

Plant, Cell &Environment, Volume 47, Issue 12, Page 5511-5526, December 2024.
Abstract Nitrogen (N) nutrition impacts on primary carbon metabolism and can lead to changes in δ13C of respired CO2. However, uncertainty remains as to whether (1) the effect of N nutrition is observed in all species, (2) N source also impacts on respired CO2 in roots and (3) a metabolic model can be constructed to predict δ13C of respired CO2 under ...

At the crossroads: strigolactones mediate changes in cytokinin synthesis and signalling in response to nitrogen limitation

The Plant Journal, Volume 120, Issue 1, Page 139-158, October 2024.
SUMMARY Strigolactones (SLs) are key regulators of shoot growth and responses to environmental stimuli. Numerous studies have indicated that nitrogen (N) limitation induces SL biosynthesis, suggesting that SLs may play a pivotal role in coordinating systemic responses to N availability, but this idea has not been clearly demonstrated.

Amino Acid Metabolism and Transport in Soybean Plants [PDF]

, 2017
The ammonium produced by nitrogen fixation in the bacteroid is rapidly excreted to cytosol of infected cell of soybean nodules and then assimilated into glutamine and glutamic acid, by glutamine synthetase/glutamate synthase pathway. Most of the nitrogen

Comprehensive transcriptome profiling and transcription factor identification in early/late leaf senescence grafts in potato

Physiologia Plantarum, Volume 176, Issue 5, September/October 2024.
Abstract Potato (Solanum tuberosum L.) is recognized globally as the most significant non‐cereal staple crop. Leaf senescence, which significantly impacts tuber yield, serves as a critical indicator of potato maturity. Despite its importance, the molecular mechanisms regulating this process remain largely unknown.

Genetic and physiologic analyses of soybean grain yields in water limited environments [PDF]

, 2015
Increasing grain yield in soybean is an important breeding goal for plant breeders. While identification of yield QTL can result in identification of genomic regions for increasing yield, these regions are often not consistent across environments due to ...

Impact of Nodulation Efficiency and Concentrations of Soluble Sugars and Ureides on Soybean Water Deficit During Vegetative Growth

Nitrogen
Drought is the primary limiting factor affecting soybean productivity, and is exacerbated by climate change. In legumes like soybeans, biological nitrogen fixation (BNF) is the main form of nitrogen acquisition, with nitrogen being converted into ureides.
