摘要:
The present invention relates generally to the field of molecular biology and concerns a method for enhancing various economically important yield-related traits in plants. More specifically, the present invention concerns a method for enhancing yield-related traits in plants by modulating expression in a plant of a nucleic acid encoding a Yield Enhancing Protein (YEP). The YEP is selected from a Vacuolar Processing Enzyme (VPE) or a CCA1-like polypeptide or a SAP-like polypeptide or a Seed Yield Promoting Factor 1 (SYPF1) polypeptide or a Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) activase (RCA) polypeptide. The present invention also concerns plants having modulated expression of a nucleic acid encoding such a YEP, which plants have enhanced yield-related traits relative to control plants. The invention also provides hitherto unknown YEP-encoding nucleic acids, and constructs comprising the same, useful in performing the methods of the invention.

摘要:
The present invention relates to a method for modifying plant growth and development processes by affecting cell cycle regulation comprising modulating expression of members of the plant E2F transcription factor family. More specific the invention relates to methods for stimulating cell division in a plant. The invention further relates to transgenic plants produced by the methods of the invention having altered plant growth and development characteristics compared to their isogenic counterparts. Preferably, the plant characteristics modified by the present invention include enlarged cotyledons, enhanced growth rate, stress resistance and seedling survival, more cells, more tillers, more panicles.

The present invention concerns a method for modifying the growth characteristics of plants by modulating expression in a plant of a B-type CDK nucleic acid and/or modulating activity and/or levels in a plant of a B-type CDK protein. The invention also relates to transgenic plants having modified growth characteristics, which plants have modulated expression of a B-type CDK nucleic acid and/or modulated activity and/or levels in a plant of a B-type CDK protein relative to expression, activity and/or levels in corresponding wild-type plants. The present invention also provides a novel screening method for the identification of mutant CDKs having enhanced CDK activity relative to corresponding non-mutated CDKs. The present invention also provides a novel screening method for the identification of non-active CDKs that are able to bind to CKIs (cyclin dependent kinase inhibitors). The invention also provides mutant CDKs obtainable by the screening methods according to the invention.

The present invention provides nutritional compositions, more particularly food supplements and processed food products, enriched with arabinoxylan-oligosaccharides and further comprising either or both water-unextractable arabinoxylans or water-soluble arabinoxylans. Preferably said nutritional compositions comprises both arabinoxylan-oligosaccharides and water-unextractable arabinoxylans.
摘要:
The invention relates to a method for identifying and validating plant targets for agrochemicals, comprising the steps of determining gene or protein expression profiles in function of the progression of an essential biological process in a plant subsequent downregulation of expression of said gene or protein in a plant cell. More particularly, the effects of downregulation of the candidate target gene were directly monitored on plants locally infected with a vector mediating viral induced gene suppression in that infected plant area. The invention also relates to isolated plant genes encoding proteins involved in plant growth and development. The invention also relates to plants tolerant to agrochemicals such as herbicides or pesticides.
摘要:
The present invention relates to the use of oligosaccharides derived from arabinoxylan for use in the prevention and treatment of gastrointestinal infection. More particularly the invention provides a method for preventing or reducing the gastrointestinal infection of a animal or human being with bacteria associated with gastroenteritis through the supplementation of their diets with the said oligosaccharides.
摘要:
The present invention relates to preparations comprising (arabino)xylan oligosaccharides with average degree of polymerisation between 4 and 10 and average degree of arabinose substitution between 0.15 and 0.35, which beneficially modulate the intestinal flora, such preparation comprising both xylo- and arabinoxylo-oligosaccharides. Preferably, the arabinoxylooligosaccharides are substituted in part by hydroxycinnamic acids and exert antioxidant effects. Furthermore, it is preferred that the preparations according to the present invention have a nitrogen content below 0.16% (w/w) in order to ensure good organoleptic and colour properties, particularly upon heating said preparations. In addition, food, beverage and nutritional supplement products comprising the preparations are provided as well as methods to prepare the said preparations.
摘要:
This invention provides beers with increased amounts of soluble arabinoxylans having an average degree of polymerisation (DP) below 50 for improving or significantly altering their mouthfeel. This invention also provides methods for enriching a wort or beer with such soluble arabinoxylans during the brewing process.
