Hi everyone, I recently came across some interesting information about bio fungicides that use fungus to prevent the spread of pathogens. Usually, when a plant fights off disease, plant growth is limited. But accessing microbes allows the plant to maintain average growth while also preventing persistent infection. Microbes help produce induced systemic resistance (ISR), an immunity boost that helps the plant. When designing a resistant crop to a pathogen, a geneticist wants resistance genes (R-gene) immune to one disease strain. But using ISR lends to multiple modes of action against infection. Microbes' influence on plants is related to the jasmonic acid hormone. This hormone limits disease but slows plant growth significantly. Trichoderma is a microbe that acts as a bio fungicide. One compound, 12-OPDA, was a familiar building block for jasmonic acid. But unlike jasmonic acid, this compound may not inhibit plant growth. In addition, the analysis showed that Trichoderma sends chemical signals to encourage plants to produce 12-OPDA and discourage them from using up 12-OPDA to make jasmonic acid. Understanding these microbes and others could lead to significant steps in disease resistance affecting crops! I am trying a biological product that has a large amount of Trichoderma and am excited to understand the plant growth stimuli side and the reaction to biotic conditions! What are everyone's thoughts?
