摘要:
The invention concerns a novel plant promoter capable of directing the expression of a nucleotide sequence of interest in the cells of a plant root, and recombinant vectors containing such a promoter, preferably associated with a nucleotide sequence whereof the expression is desired in constitutive cells of plant roots.

Le dispositif comprend des premiers moyens de support (1) d'une tige de mesure (2) dont une extrémité (2a) est conçue pour supporter un embout de travail (3) destiné à venir en contact avec le produit (10). Lesdits premiers moyens de support (1) sont montés à translation par rapport à une vis sans fin (4) qui s'étend parallèlement à la tige de mesure (2) et qui est entraînée en rotation par des moyens moteurs (5), tandis que le produit est disposé sur des seconds moyens de support (6) formant capteurs de mesure qui sont reliés à des moyens informatiques (8) programmés pour traiter et stocker les mesures réalisées par le dispositif. Application à l'évaluation de la fermeté des fruits et des légumes ou de tout autre objet solide comparable.
摘要:
The invention concerns a method for detecting the PVY virus which consists in a SNP test or an extension reaction specific to mutations corresponding to R/K400 et D/E419, the presence of at least one of said mutations indicating the presence of at least one virulent PVY strain capable of causing necrosis in plants of the Solanaceae family, in particular in potatoes.
摘要:
An acid-stable β-glucosidase that may be prepared from filamentous fungi and has very low glucose inhibition sensitivity is disclosed. Said β-glucosidase is particularly useful for preparing fruit juices and in enzymatic cellulose hydrolysis methods.
摘要:
Use of fatty acids selected from the group comprising palmitic acid, palmitoleic acid, oleic acid, myristic acid, stearic acid, linolenic acid and linoleic acid, optionally combined with their ethyl or methyl esters for the protection of plants against pests.
摘要:
A reactor for sterile solid-state fermentation methods, including a double-wall (3) vessel (1) with a door (10) in its lower portion, a lid in its upper portion, a grate (15) near the bottom of the vessel (1), a stirring assembly (17) rotatable about two vertical axes (X-X; Y-Y) under the control of a drive unit (M) and a planetary driving system (29), a circuit for circulating a gas through the vessel (1) between an inlet (C3) and an outlet (C15), and systems for controlling the temperature and moisture of the material being grown. The reactor is suitable for carrying out solid-state fermentation methods under completely sterile conditions.
摘要:
Method for the treatment of suidae, particularly pigs in order to improve the quality of the meat, and particularly its water retention capacity, by incorporating glycerol, one of its precursors or one of its metabolites. The pigs are treated by adding to the food approximately 5 % glycerol at the end of the growth period, i.e. is to say just before slaughtering.
