Also provided recombinant nucleic acids encoding the glycosidases, transformed cells comprising the same and related methods of using the transformed cells and glycosidases to degrade cellulose and/or hemicellulose.
摘要:
A method for the identification of peptides having an affinity for the surface of fungi is provided as is a method for the identification of peptides capable of affecting the development of a fungus. Also provided are compositions comprising peptides identified using the method of the present invention. In addition, isolated polynucleotides, vectors, expression cassettes and transformed cells capable of expressing peptides identified by the method of the present invention are provided. Such polynucleotides, vectors, expression cassettes may be introduced into and confer upon plants the capability to resist fungal infection.

The instant invention relates to a method of inducing resistance to pathogens including fungi in transgenic plants by introducing into the plants a first sequence encoding a plant defense peptide and a second sequence encoding a peptide delivery scaffold.
摘要:
An ostomy appliance is described in the form of a controlled discharge device for controlling discharge from the stoma and/or an ostomy pouch for collecting discharged waste. The appliance may include one or more of: an elastomeric stoma seal for providing a seal around or directly against the stoma; a stoma occluder for occluding the stoma without passing internally into the stoma; a peristomal foam wall; a confinement seal for confining at least solid excreta to a confinement region adjacent to the stoma; a stowable collector bag; and interchangeable controlled discharge devices and ostomy pouches. The foam wall may provide a barrier to stool, but allow escape of flatus. The foam wall and/or the stoma occluder and/or the confinement seal may apply a force in a direction to increase the sealing force on the stoma seal.
摘要:
A phytohormone for inducing root hair curling and root nodulation in the roots of leguminous plants particularly in the absence of nitrogen-fixing bacteria. The phytohormone comprises a pentasaccharide having a fatty acid condensed on the non-reducing end. A method for treating the roots of leguminous plants for inducing root hair curling and root nodulation is also disclosed.

Recombinant DNA clones according to the invention contain nodABCDIJL genes of B. japonicum. These clones can be used to practice a method wherein a nod- strain of Rhizobium or Bradyrhizobium bacteria lacking one or more of these genes is converted to a nod+ strain by transfering one or more of the missing genes to the strain. According to a further aspect of the invention, nucleotide sequences have been identified which control the expression of nod LABC genes of Bradyrhizobium japonicum in the presence of flavones produced by the plant roots. By linking such sequences with a gene having a desired characteristic, such as a gene encoding for production of a plant parasite toxin, bacterial can be created which selectively express the characteristic only in the presence of the flavone which triggers expression of the gene.
摘要:
Perception of chitin fragments (chitooligosaccharides) is an important first step in plant defense response against fungal pathogen. LysM receptor-like kinases (LysM RLKs) are instrumental in this perception process. LysM RLKs also play a role in activating transcription of chitin-responsive genes (CRGs) in plants. Mutations in the LysM kinase receptor genes or the downstream CRGs may affect the fungal susceptibility of a plant. Mutations in LysM RLKs or transgenes carrying the same may be beneficial in imparting resistance against fungal pathogens.
