Nitrate assimilation: Influence of nitrogen supply

Use of transcriptomics and co-expression networks to analyze the interconnections between nitrogen assimilation and photorespiratory metabolism

“…2005 ). Moreover, previous works have shown that the concentrations of the different nitrogen sources used here are not toxic for L. japonicus ( Orea et al , 2005 ). After all the plants had reached the same size (an average of seven trefoils), leaf tissue was harvested.…”

“…Two NAC transcription factors (probesets Ljwgs_045720.1 and Ljwgs_055404.1) correspond to Arabidopsis VNI2 and NTL9, which regulate leaf longevity and senescence ( Yoon et al , 2008 ; Yang et al , 2011 ). These transcription factors may be related to the fact that the growth of plants cultivated with NH 4 NO 3 can surpass the maximal growth compared with either NO 3 − or NH 4 + alone ( Orea et al , 2005 ).…”

“…Plants under different forms of nitrogen nutrition were watered with ‘Hornum’ nutrient solution containing 10mM KNO 3 (NO 3 − plants), 10mM NH 4 Cl supplemented with 3mM KCl (NH 4 + plants), or 5mM NH 4 NO 3 supplemented with 3mM KNO 3 (NH 4 NO 3 plants). The nutrient solutions were renewed every 3 d. These nutritional conditions were used taking into consideration the recommended growth conditions for L. japonicus ( Handberg and Stougaard, 1992 ; Orea et al, . 2005 ).…”

Biochemical and Structural Studies of LjSK1, a Lotus japonicus GSK3β/SHAGGY-like Kinase, Reveal Its Functional Role

“…4,5 The legume, Lotus japonicus (Regel) K. Larsen (Leguminosae), is a model plant system 6 for the study of its symbiotic relationship with nitrogen fixing bacteria. 7 Six proteins (LjSK1−6) homologous to GSK3 have been identified in the L. japonicus nodule. 3,8 The genes encoding LjSK1 and LjSK6 respond to symbiotic bacterial infection at the transcript level, while LjSK1 is strongly linked to nodulation and lateral root development.…”
