Biosynthesis of 5-aminolevulinic acid via the Shemin pathway in a green sugar beet callus Inra
Bisbis, B.; Billard, J.P.; Huault, C.; Kevers, C.; Le Dily, F.; Gaspar, T..
5-Aminolevulinic acid synthase (ALAS) has been detected in a normal (auxin- and cytokinin-dependent) green sugar beet callus under light and under darkness. ALAS activity was lower when the callus was grown under light. The supply of precursors of the Shemin pathway (glycine and succinate) to dark-grown callus enhanced considerably the capacity of the 5-aminolevulinic acid (ALA) formation. Glutamate, γ-aminobutyrate or α-ketoglutarate also increased ALA accumulation. Such an accumulation was also obtained after inhibition of polyamine synthesis. The results show that glutamate or its derivatives might feed the Shemin pathway in conditions preventing glutamate to be used through the Beale pathway.

Glutamine,arginine and the amino acid transporter Pt-CAT11 play important roles during senescence in poplar Inra
Couturier, J.; Doidy, J.; Guinet, F.; Wipf, D.; Blaudez, D.; Chalot, M..
Background and Aims Nitrogen (N) availability in the forest soil is extremely low and N economy has a special importance in woody plants that are able to cope with seasonal periods of growth and development over many years. Here we report on the analysis of amino acid pools and expression of key genes in the perennial species Populus trichocarpa during autumn senescence.Methods Amino acid pools were measured throughout senescence. Expression analysis of arginine synthesis genes and cationic amino acid transporter (CAT) genes during senescence was performed. Heterologous expression in yeast mutants was performed to study Pt-CAT11 function in detail.Key Results Analysis of amino acid pools showed an increase of glutamine in leaves and an accumulation of...

The arginine deiminase locus of Oenococcus oeni includes a putative arginyl-tRNA synthetase ArgS2 at its 3'-end Inra
Nehmé, B.; Ganga, M.A.; Lonvaud-Funel, A..
Oenococcus oeni is the most important lactic acid bacteria of the winemaking process involved in malolactic fermentation. Most O. oeni strains are able to catabolyze arginine via the arginine deiminase (ADI) pathway. The arcR, A, B, C, D1, and D2 cluster of O. oeni bacteria has been characterized. Here, we completed the ADI locus sequence. Downstream of arcD2 gene, we found an additional gene which encodes a putative arginyl-tRNA synthetase (argS2). It is not the same arginyl-tRNA synthetase which was sequenced in O. oeni MCW strain. Transcriptional analyses have shown that argS2 was induced by arginine. In addition, systematic polymerase chain reaction amplification of each arc gene and argS2 has provided a characteristic feature of the ADI locus within...

Variations quantitatives en composés azotés et glucidiques de racines d’asperges, mâles et femelles, au cours de leur première année de culture Inra
Fiala, V.; Jolivet, E..
Cette étude montre que l’accumulation des réserves azotées et carbonées dans des racines d’asperge commence très tôt dès le troisième mois après la germination, au cours de la première année de culture. Tant chez les plantes mâles que chez les plantes femelles, les acides aminés libres composant ces réserves azotées sont formés notamment d’arginine et d’asparagine et les réserves glucidiques sont constituées de fructosanes et de saccharose.
