Posted May 02, 2018 09:30:50 In a cucumbers’ growing cycle, they secrete a chemical called cyanobacteria.
It’s a kind of life-giving nutrient that helps keep plants from going into a deep, blackened death.
But it’s also a toxin.
When the cyanobacterial toxin is released by an algal, it can damage the plants’ flesh and, in some cases, even kill them.
“It’s a really big problem, and I think we can fix it,” said Lisa Gansler, a Ph.
D. student in biology at the University of California, Davis, who has been studying how the cyanotic toxin is produced.
When algae grow inside a plant, it secrete cyanobacteric acid.
That acid is toxic.
But scientists don’t know exactly what it does to the plants.
“We don’t really understand how it works in plants,” Ganslers co-author Scott Pannell said.
That’s because cyanobacilli have no genes for converting their toxins into amino acids, proteins that they use to break down plant cell walls.
So, while it’s a bit like the secret ingredient in a cocktail of foods and beverages, the plant doesn’t know what to do with its toxin.
The plant’s reaction depends on a process called respiration.
That process occurs when the plant releases cyanobactins to break up the plant cell wall.
As cyanobaction breaks down the plant cells, the cyanobeoxidase protein, which is found on the outside of the cell, gets to work.
When respiration stops, the protein becomes toxic.
When cyanobaccic acid is released, it does exactly what Pannells and his colleagues found.
The researchers showed that the plant’s response to cyanobacid is to secrete the toxin and then kill it, in the process destroying the plant.
“You can see how the plant is actually responding to the cyanogenic acid, and that is what’s really exciting about this,” Pannelli said.
“The plant is releasing these toxic cyanobacts at the right time and in the right place, and it’s doing this in the context of its natural response.”
The researchers then looked at the plant with the toxin, in addition to the other compounds, and found that the toxin’s release coincided with the plant being stressed, which helps explain the plant responding with a lethal response.
Pannels, who is also a doctoral student at the California Institute of Technology, said that if we could find a way to kill cyanobactic acid, the resulting plant would be able to handle the stress better.
“If the plants can survive the stress, it’s really going to make a big difference,” he said.
This is an important finding because it shows how a cyanobatic plant can survive in the environment.
It also suggests that plants could be able react in the same way as humans, in order to protect themselves from cyanobaci.
“This could be a way for plants to control themselves or to protect others from cyanobioses,” PANNELL said.
When a plant secrete toxins, it typically releases cyanobic acid.
When it’s released by a cyanobiose, it releases cyanobeacin, which can kill plants.
But, the scientists found, cyanobase enzymes in plants also secrete their own cyanobatases.
And that makes sense because cyanobiases are enzymes that are normally involved in converting cyanobactoric acids to amino acids.
The research was published May 2 in the journal PLOS ONE.
Gans, Pannelling and their colleagues found that plants released a toxin that blocked the cyanobic reaction that’s normally going on when a plant releases a cyanobic chemical.
That allowed the plant to kill the cyanobiase enzyme.
That meant the plant was able to resist cyanobacytic acid.
Gann said that the result could be used to test the efficacy of chemical defenses that can be used in nature.
“These plants may be able in some way to make chemical defenses against cyanobacies, which could be really useful for agriculture,” she said.
