A unigene catalogue of 5700 expressed genes in cassava Inra
Lopez, C.; Jorge, V.; Piégu, B.; Mba, C.; Cortes, D.; Restrepo, S.; Soto, M.; Laudié, M.; Berger, C.; Cooke, R.; Delseny, M.; Tohme, J.; Verdier, V..
Two economically important characters, starch content and cassava bacterial blight resistance, were targeted to generate a large collection of cassava ESTs. Two libraries were constructed from cassava root tissues of varieties with high and low starch contents. Other libraries were constructed from plant tissues challenged by the pathogen Xanthomonas axonopodis pv. manihotis. We report here the single pass sequencing of 11 954 cDNA clones from the 5' ends, including 111 from the 3' ends. Cluster analysis permitted the identification of a unigene set of 5700 sequences. Sequence analyses permitted the assignment of a putative functional category for 37% of sequences whereas ~16% sequences did not show any significant similarity with other proteins present in...

An EST resource for cassava and other species of Euphorbiaceae Inra
Anderson, J.V.; Delseny, M.; Fregene, M.A.; Jorge, V.; Mba, C.; Lopez, C.; Restrepo, S.; Soto, M.; Piégu, B.; Verdier, V.; Cooke, R.; Tohme, J..
Cassava (Manihot esculenta) is a major food staple for nearly 600 million people in Africa, Asia, and Latin America. Major losses in yield result from biotic and abiotic stresses that include diseases such as Cassava Mosaic Disease (CMD) and Cassava Bacterial Blight (CBB), drought, and acid soils. Additional losses also occur from deterioration during the post-harvest storage of roots. To help cassava breeders overcome these obstacles, the scientific community has turned to modern genomics approaches to identify key genetic characteristics associated with resistance to these yield-limiting factors. One approach for developing a genomics program requires the development of ESTs (expressed sequence tags). To date, nearly 23000 ESTs have been developed from...

Free fat, surface fat and dairy powders: interactions between process and product. A review Inra
Vignolles, M.L.; Jeantet, R.; Lopez, C.; Schuck, P..
Nowadays, fat-filled spray-dried dairy powders have acquired an economic importance.Increasing the fat content leads to further quality implications such as off-flavors, and poor rehydration and flowing properties. However, the control of the drying operation and of the powder properties is still rather empirical in this case and few studies have focused on the whole issue up to now. This review aims at giving an overview of research work on fat-filled powders. The so-called“free fat” is often related to fat-filled powders, but the review also highlights the relevance of “surface fat” to powder physical properties. Quantitative and qualitative analytical techniques, mainly referring to free fat, are described here. This review focuses on the specific and...

Lipolysis during ripening of emmental cheese considering organization of fat and preferential localization of bacteria Inra
Lopez, C.; Maillard, M.B.; Briard-Bion, V.; Camier, B.; Hannon, J.A..
This study followed the progression of lipolysis in Emmental cheese by quantifying the concentrationsof individual free fatty acids (FFA) released during ripening in each of the different rooms: 12 daysat 12 °C, 28 days at 21 °C, and 8 days at 4 °C. Lipolysis, which corresponded to 1.56% of fat, mainlyoccurred in the 21 and 4 °C rooms, with 68 and 16.5% of total FFA, respectively. The nonselectivityof lipolytic enzymes was evidenced: all fatty acids were released with level of g1%. Differentialscanning calorimetry experiments showed that the thermal properties of cheese were affected by (i)lipolysis of fat, that is, the monoacylglycerols, diacylglycerols, and FFA that may be localized at thefat/whey interface, and/or by (ii) hydrolysis of...

Recent progress in the characterization of molecular determinants in the Xanthomonas axonopodis pv. manihotis-cassava interaction Inra
Verdier, V.; Restrepo, S.; Mosquera, G.; Jorge, V.; Lopez, C..
Cassava bacterial blight, caused by xanthomonas axonopodis pv. manihotis (Xam), is a widespread disease that affects cassava (Manihot esculenta Crantz). Studies on the pathogen population structure, pathogen diagnosis, identification and expression of plant genes involved in resistance have been carried out. Different molecular techniques were developed to assess the genetic diversity among the Xampopulations. Characterization of Xam population dynamics over time had enable us to determine the different factors that are associated with resistance breakdown and those that influence the genetic structure or virulence phenotypes of the pathogen’s population. Methods for detecting the pathogen in vegetative planting materials and true seeds were developed and...

Thermal and structural behavior of anhydrous milk fat. 3. Influence of cooling rate Inra
Lopez, C.; Lesieur, P.; Bourgaux, C.; Ollivon, M..
The crystallization behavior of anhydrous milk fat has been examined with a new instrument coupling time-resolved synchrotron x-ray diffraction as a function of temperature (XRDT) at both small and wide angles and high-sensitivity differential scanning calorimetry. Crystallizations were monitored at cooling rates of 3 and 1°C/ min from 60 to –10°C to determine the triacylglycerol organizations formed. Simultaneous thermal analysis permitted the correlation of the formation/melting of the different crystalline species monitored by XRDT to the thermal events recorded by differential scanning calorimetry. At intermediate cooling rates, milk fat triacylglycerols sequentially crystallize in 3 different lamellar structures with double-chain length of 46 and 38.5...
