摘要:
An L-glutamic acid producing bacterium which belongs to the genus Pantoea, Enterobacter, Klebsiella or Erwinia, wherein the bacterium has been modified by gene recombination to inactivate the rpoS gene, is cultured in a medium to cause accumulation of L-glutamic acid in the medium, and L-glutamic acid is collected from the medium.
摘要:
Peptides of influenza virus hemagglutinin protein and Plasmodium falciparum malaria antigen, antibodies specific for the peptides, influenza vaccines, malaria vaccines and methods of stimulating the immune response of a subject to produce antibodies to influenza virus or malaria are disclosed. Also disclosed are methods for formulating vaccines for influenza virus.
摘要:
The present invention relates to a biopesticide using a plant pathogen, and more particularly, to a biopesticide having an improved resistance against plant pathogens and an improved plant growth effect, which is superior to that of HrpN, a plant-senstive protein isolated from Erwinia amylovora ATCC 15580, by using a gene isolated from WT#3(Erwinia pyrifoliae WT#3)[KCCM 10283] thus enabling to be used as a fertilizer as well a biopesticide.
摘要:
An isolated polypeptide which elicits a hypersensitive response in different plant species when said polypeptide is introduced into tissue of a plant. The polypeptide is from an Erwinia pathogen.
摘要:
The present invention relates to a method of imparting pathogen resistance to plants. This involves applying a hypersensitive response elicitor polypeptide or protein in a non-infectious form to a plant under conditions where the polypeptide or protein contacts cells of the plant. The present invention is also directed to a pathogen resistant plant and a composition for imparting pathogen resistance to plants.
摘要:
DNA sequences encoding for ice nucleation activity are isolated and introduced into unicellular hosts. The modified hosts demonstrate ice nucleation activity analogous to the DNA source host. The cellular products find use in inhibiting supercooling.
摘要:
The present invention relates to a method for identification and detection of pectinolytic bacteria of the genus Erwinia of predetermined species, subspecies or pathovar, and more particularly of the species Erwinia chrysanthemi and of the species Erwinia carotovora, in the ground or in the water, or in a host susceptible of being the carrier of such bateria, particularly in plants and seeds, such process comprising assaying for fragments of DNA or RNA, which are specific of the concerned species, coding a pectate-lyase (PL), through a molecular hybridization with at least one specific probe, such hybridization being preceded by an amplification of the number of copies of the above-mentioned DNA fragments by means of specific primers. The invention also relates to probes and primers as well as to kits containing them for implementing such method.
摘要:
Procédé de production d'un agent de nucléation de glace sans cellule comprenant les étapes consistant: i) à mettre en culture un micro-organisme génerant des bulles capables de produire une protéine de nucléation de glace, la mise en culture s'effectuant à une première température favorisant la phase de croissance du micro-organisme, et étant poursuivie jusqu'à obtention d'une phase stationnaire; ii) à mettre en culture le micro-organisme produisant des bulles pendant une phase stationnaire, à une seconde température inférieure à la première température et efficace pour stimuler la production de protéine active de nucléation de glace sans cellule; iii) à séparer la protéine active de nucléation de glace sans cellule du micro-organisme.
摘要:
Disclosed are peptides that induce an active plant response, but not a hypersensitive response, when applied to plant tissue. These peptides also preferably exhibit improved solubility, stability, resistance to chemical degradation, or a combination of these properties. Use of these peptides or fusion polypeptides, or DNA constructs encoding the same, for modulating plant biochemical signaling, imparting disease resistance to plants, enhancing plant growth, imparting tolerance to biotic stress, imparting tolerance and resistance to abiotic stress, imparting desiccation resistance to cuttings removed from ornamental plants, imparting post-harvest disease or post-harvest desiccation resistance to a fruit or vegetable, or enhancing the longevity of fruit or vegetable ripeness are also disclosed.
