摘要:
A composition-of-matter for mosquito control is provided. The composition comprises a cell which comprises an exogenous naked dsRNA which specifically down- regulates expression of a gene being endogenous to a mosquito or which specifically down-regulated expression of a gene being endogenous to a mosquito pathogen. Further provided is a composition-of-matter for mosquito control, comprising a cell comprising a nucleic acid larvicide. Also provided are methods of producing and using the compositions.
摘要:
A method of enhancing larvicide susceptibility in a mosquito larva is provided. The method comprising introducing into the mosquito larva an isolated nucleic acid agent comprising a nucleic acid sequence which specifically reduces the expression of at least one larvicide resistance gene product of the larva, thereby enhancing larvicide susceptibility in said mosquito larva.
摘要:
The present invention relates to a method for modulating plant processes said method being characterized in that a plant is fed with an eco-friendly, plant- and/or algae-derived, biostimulant composition comprising exogenous small RNA molecules. In particular, the method of the invention can be used for modulating physiological or pathological plant processes, such plant growth, plant productivity, fruit quality, quality of produce, plant yield, plant response to abiotic stress and plant resistance to diseases or to infections.
摘要:
The present invention, in some embodiments thereof, relates to methods for enhancing fitness of pathogen-infected plants, and, more particularly, but not exclusively, to methods of using RNA interference for modulation of plant-pathogen resistance response gene expression. In particular, the present invention provides compositions and methods for enhancing host plant fitness and fruit yield and quality following Candidatus Liberibacter spp infection and, specifically, Candidatus Liberibacter spp infection in citrus plants and trees, as in Huang Long Bing.

The disclosure describes an algal system for improving water quality through the use of algae. In example embodiments, the algal system comprises an elongate device including algae enclosed therein and capable of reducing at least the levels of nitrates and phosphates in water directed through the device. The algae may be capable of also reducing E. coli bacteria, other bacteria, and viruses in the water. Preferably, the algae comprises a filamentous green algae, including without limitation, Spirogyra grevilleana algae. In one example embodiment, the algal system comprises an elongate device and an elongate cartridge that is pre-configured to treat certain chemical compounds, bacteria, and viruses, and certain other characteristics of water. The cartridge is delivered to the site where the water is to be treated and installed in the field, possibly replacing an existing cartridge. After use, algae may be processed into biofuel.

The present invention relates to a product Kappaphycus alvarezii seaweed sap free of Gibberellic acid (GA3) and its method of preparation. Kappaphycus alvarezii seaweed sap is a plant stimulant found to enhance yield and quality of a number of crops. Besides containing many macro- and micro- nutrients, there are many plant growth hormones present in Kappaphycus alvarezii sap. It has been observed that pristine Kappaphycus alvarezii sap and GA3 free sap enhanced grain yield but surprisingly selective removal of GA3 from the pristine sap had profound stimulating effect on total dry above ground biomass yield of maize over and above the pristine sap. Upon seed treatment with GA3 free sap, ?-amylase enzyme activity in the germinating seed of mung bean is found to be increased. The foliar spray of GA3 free sap on tomato plants upregulated disease responsive genes (PR-3 and PR-5) as compared to pristine sap.

摘要:
A process for extraction of bioactive organic compounds from alkali extracts of Ascophyllum nodosum . Organic solvent extracts of A. nodosum namely; methanol, chloroform and ethylacetate, were found to alleviate salt induced stress in plants. This effect was due to alteration in the expression of a specific subset of genes induced by compounds present in A. nodosum extracts.
