Other Recent Advances
RNA interference (RNAi) is a technology that allows for the specific down-regulation of genes and is a powerful tool for the identification of new targets for crop protection compounds. Whilst a crop protection compound inhibits its target protein, often an enzyme catalysing a specific metabolic step, RNAi targets the messenger RNA which encodes this enzyme and in consequence reduces the amount of the enzyme itself. Thus, RNAi is capable of mimicking the action of crop protection compounds. The availability of genome sequences for several model organisms made gene sequences available and provided the necessary information to target any gene of interest by using RNAi.
The biopesticide is based on fusion protein technology. This allows selected toxins from arthropods, which have no toxicity towards higher animals, to be combined with a carrier protein that makes them orally toxic to invertebrates, whereas they would normally only be effective when injected into a prey organism by a predator. The fusion protein, containing both the toxin and the carrier, is produced as a recombinant protein in a microbial expression system, which can be scaled up for industrial production.
Seed mat technology is ‘advancing crop technology’ by replacing agrochemicals for weed, pest and disease control by the use of advanced seed mat systems that also reduce water and labour requirement whilst improving food safety, quality and shelf life.
There are many ways the environment can be altered or managed to reduce plant diseases. Some of them include temperature, irrigation, humidity and host nutrition (fertiliser).
