A combined proteome and transcriptome analysis of developing Medicago truncatula seeds: evidence for metabolic specialization of maternal and filial tissues Inra
Gallardo, K.; Firnhaber, C.; Zuber, H.; Héricher, D.; Belghazi, M.; Henry, C.; Küster, H.; Thompson, R..
A comparative study of proteome and transcriptome changes during Medicago truncatula (cultivar Jemalong) seed development has been carried out. Transcript and protein profiles were parallel across the time course for 50% of the comparisons made, but divergent patterns were also observed, indicative of post-transcriptional events. These data, combined with the analysis of transcript and protein distribution in the isolated seed coat, endosperm, and embryo, demonstrated the major contribution made to the embryo by the surrounding tissues. First, a remarkable compartmentalization of enzymes involved in methionine biosynthesis between the seed tissues was revealed that may regulate the availability of sulfur-containing amino acids for embryo protein synthesis...

An in vivo experimental system to study sugar phloem unloading in ripening grape berries during water deficiency stress Inra
Wang, Z.P.; Deloire, A.; Carbonneau, A.; Federspiel, B.; Lopez, F..
An in vivo experimental system-called the 'berry-cup' technique-was developed to study sugar phloem unloading and the accumulation of sugar in ripening grape berries. The berry-cup system consists of a single peeled grape berry immersed in a buffer solution in a cup prepared from a polypropylene syringe. A small cross-incision (2 mm in length) is made on the stylar remnant of a berry during its ripening phase, the skin of the berry then being easily peeled off, exposing the dorsal vascular bundles without damaging either these or the pulp tissue of the berry. The sites of sugar phloem unloading are thus made directly accessible and may be regulated by the buffer solution. In addition, the unloaded photoassimilates are easily transported into the buffer...

Body fluid of the honey bee larva - I. Osmotic pressure, specific gravity, pH, O2 capacity, CO2 capacity, and buffer value, and their changes with larval activity and metamorphosis National Institute of Agronomic Research
Bishop, George H..
1. Specific gravity of mature larvae of worker honey bees is 1.045. 2. The osmotic pressure of worker larval blood in terms of freezing point lowering gives a value of -0.86°C., and the osmotic pressure decreases during pupation. 3. The pH of larval blood (measured at 25°) is near 6.8, varying with conditions in the hive. 4. The oxygen capacity of larval blood is within a reasonable error the amount that could be physically dissolved, and no evidence of a chemical carrier is found. The content decreases during spinning, when the larva is enclosed in a cocoon, because diffusion is cut down while consumption increases. 5. CO2 absorption curves indicate that the blood (of drone larvae) decreases in CO2 capacity and content during spinning of the cocoon, but...

Combining ecophysiological modelling and quantitative trait locus analysis to identify key elementary processes underlying tomato fruit sugar concentration Inra
Prudent, M.; Lecomte, A.; Bouchet, J.P.; Bertin, N.; Causse, M.; Génard, M..
A mechanistic model predicting the accumulation of tomato fruit sugars was developed in order (i) to dissect the relative influence of three underlying processes: assimilate supply (S), metabolic transformation of sugars into other compounds (M), and dilution by water uptake (D); and (ii) to estimate the genetic variability of S, M, and D. The latter was estimated in a population of 20 introgression lines derived from the introgression of a wild tomato species (Solanum chmielewskii) into S. lycopersicum, grown under two contrasted fruit load conditions. Low load systematically decreased D in the whole population, while S and M were targets of genotype×fruit load interactions. The sugar concentration positively correlated to S and D when the variation was...

Gene transcription in Lactarius quietus-Quercus petraea ectomycorrhizas from a forest soil Inra
Courty, P.E.; Poletto, M; Duchaussoy, F.; Buee, M.; Garbaye, J.; Martin, F..
Extracting fungal mRNA from ectomycorrhizas (ECMs) and forest soil samples for monitoring in situ metabolic activities is a significant challenge when studying the role of ECMs in biogeochemical cycles. A robust, simple, rapid, and effective method was developed for extracting RNA from rhizospheric soil and ECMs by adapting previous grinding and lysis methods. The quality and yield of the extracted RNA were sufficient to be used for reverse transcription. RNA extracted from ECMs of Lactarius quietus in a 100-year-old oak stand was used to construct a cDNA library and sequence expressed sequence tags. The transcripts of many genes involved in primary metabolism and in the degradation of organic matter were found. The transcription levels of four...

Status of black-grass (Alopecurus myosuroides) resistance to acetyl-coenzyme A carboxylase inhibitors in France Inra
Délye, C.; Menchari, Y.; Guillemin, J.P.; Matéjicek, A.; Michel, S.; Camilleri, C.; Chauvel, B..
We assessed the contributions of target site- and non-target site-based resistance to herbicides inhibiting acetyl-coenzyme A carboxylase (ACC) in Alopecurus myosuroides (black grass). A total of 243 A. myosuroides populations collected across France were analysed using herbicide sensitivity bioassay (24 300 seedlings analysed) and ACC genotyping (13 188 seedlings analysed). Seedlings resistant to at least one ACC-inhibiting herbicide were detected in 99.2% of the populations. Mutant, resistant ACC allele(s) were detected in 56.8% of the populations. Among the five resistant ACC alleles known in A. myosuroides, alleles containing an isoleucine-to-leucine substitution at codon 1781 were predominant (59.5% of the plants containing resistant ACC alleles)....

Studies in the mode of action of royal jelly in honeybee development : III. The effect of experimental variation in diet on growth and metabolism of honeybee larvae National Institute of Agronomic Research
Dixon, S.E.; Shuel, R.W..
Norms were established for respiration, growth, and tissue composition of 0- to 72-hour-old female honeybee larvae reared in the laboratory on natural royal jelly and worker jelly diets. The worker jelly diet was then altered experimentally in the direction of royal jelly through additions of sugar and certain water-soluble acids of unknown structure extracted from royal jelly, but present in the natural diets of larvae of both female castes. In general, developmental norms were shifted in the direction of the norms of larvae fed royal jelly, but the changes were not fully co-ordinated. The added acids were strongly growth inhibitory. A high inverse association between the total water-soluble acid content of the diet and larval weight suggested that the...

Weed resistance to acetyl coenzyme A carboxylase inhibitors: an update Inra
Délye, C..
Herbicides targeting grass plastidic acetyl coenzyme A carboxylase (ACC) are effective selective graminicides. Their intensive use worldwide has selected for resistance genes in a number of grass weed species. Biochemistry and molecular biology have been the means of determining the herbicidal activity and selectivity toward crop plants of ACC-inhibiting herbicides. In recent years, elucidation of the tridimensional structure of ACC and identification of five amino acid residues within the ACC carboxyl transferase domain that are critical determinants for herbicide sensitivity shed light on the basis of ACC-based resistance to herbicides. However, metabolism-based resistance to ACC-inhibiting herbicides is much less well known, although this type of...
