Chaubet N, Philipps G, Gigot C, Guitton C, Bouvet N, Freyssinet G, Schneerman M, Weber DE.
PMID: 24201340
Theor Appl Genet. 1992 Aug;84(5):555-9. doi: 10.1007/BF00224151.

It has been previously shown that in the genome of maize the multiple copies of the histone H3 and H4 multigenic families are organized into eight to ten subfamilies each containing a variable number of copies. Each subfamily is...

Sunflower hypocotyl protoplasts have been isolated and cultured. Optimum plating density for cell division and colony formation was in the range of 5 to 7×10(4) cells/mi in an agarose medium supplemented with BAP (1 mg/l) and NAA (1 mg/l)....

The chloroplast and cytoplasmic ribosomes of euglena: I. Stability of chloroplast ribosomes prepared by an improved procedure.

A new isolation procedure has resulted in an improved yield of stable 68S chloroplast ribosomes from Euglena gracilis var. bacillaris. Chloroplasts are isolated by suspending the cells in buffer I (sorbitol, 250 mm; sucrose, 250 mm; Ficoll, 2.5% [w/v];...

Influence of Culture Conditions on the Length of the Lag Period of Chlorophyll Synthesis in Preilluminated Dark-grown Euglena.

Plant physiology

Freyssinet G.
PMID: 16659579
Plant Physiol. 1976 May;57(5):831-5. doi: 10.1104/pp.57.5.831.

Two parameters of the potentiation process, the lengths of preillumination and of the subsequent dark phase have been determined for Euglena cells which had been grown in the dark under two different culture conditions. In both cases a maximum...

Genotypic variation of quantitative trait loci controlling in vitro androgenesis in maize.

Genome

Murigneux A, Bentolila S, Hardy T, Baud S, Guitton C, Jullien H, Tahar SB, Freyssinet G, Beckert M.
PMID: 18470136
Genome. 1994 Dec;37(6):970-6. doi: 10.1139/g94-137.

A quantitative trait loci (QTL) analysis for androgenetic capability has been conducted on three different crosses in maize, including very high and nonresponding lines for androgenesis. The doubled haploid lines derived by anther culture from the crosses DH5 x...

Does high mitochondrial efficiency carry an oxidative cost? The case of the African pygmy mouse (Mus mattheyi).

Comparative biochemistry and physiology. Part A, Molecular & integrative physiology

Boël M, Veyrunes F, Durieux AC, Freyssenet D, Voituron Y, Roussel D.
PMID: 34748935
Comp Biochem Physiol A Mol Integr Physiol. 2021 Nov 05;264:111111. doi: 10.1016/j.cbpa.2021.111111. Epub 2021 Nov 05.

Skeletal muscle mitochondria of the African pygmy mouse Mus mattheyi exhibit markedly reduced oxygen consumption and ATP synthesis rates but a higher mitochondrial efficiency than what would be expected from allometric trends. In the present study, we assessed whether...

Early Deconditioning of Human Skeletal Muscles and the Effects of a Thigh Cuff Countermeasure.

International journal of molecular sciences

Fovet T, Guilhot C, Stevens L, Montel V, Delobel P, Roumanille R, Semporé MY, Freyssenet D, Py G, Brioche T, Chopard A.
PMID: 34769492
Int J Mol Sci. 2021 Nov 08;22(21). doi: 10.3390/ijms222112064.

Muscle deconditioning is a major consequence of a wide range of conditions from spaceflight to a sedentary lifestyle, and occurs as a result of muscle inactivity, leading to a rapid decrease in muscle strength, mass, and oxidative capacity. The...

Tissue-Specific Expression of Germin-Like Oxalate Oxidase during Development and Fungal Infection of Barley Seedlings.

Plant physiology

Dumas B, Freyssinet G, Pallett KE.
PMID: 12228419
Plant Physiol. 1995 Apr;107(4):1091-1096. doi: 10.1104/pp.107.4.1091.

Oxalate oxidase activity was detected in situ during the development of barley seedlings. The presence of germin-like oxalate oxidase was confirmed by immunoblotting using an antibody directed against wheat germin produced in Escherichia coli, which is shown to cross-react...

Expression of Chloroplast and Mitochondrial Genes during Microsporogenesis in Maize.

Plant physiology

Mitochondrial and plastid gene expression has been examined during maize (Zea mays) microsporogenesis. Accumulation of transcripts was found for three mitochondrial genes studied (cob, atp6, and atp9) at the mid-term of pollen development. In contrast, these mitochondrial transcripts were...

Relation between Paramylum Content and the Length of the Lag Period of Chlorophyll Synthesis during Greening of Dark-grown Euglena gracilis.
