In addition, because we developed PhoB - VP64 for plants by activating endogenous HKs with exogenous cytokinins [12], it is likely that our synthetic signal transduction system (receptor → HK → PhoB: VP64 → signal receptive promoter) has false input or cross-talk from plant HK components.
So, De La Torre saw nematodes activated cytokinin responses in the plant early after infection when her plants emitted a green fluorescent glow under the microscope.
The scientists blocked cytokinin production in the plant — the nematode nevertheless continued to grow because it was not dependent on the plant - produced hormone.

Coconut water contains a compound called cytokinin, which protects cells from aging and cancer.
The system is partially synthetic as it requires input from plant HK components (e.g., HKs, histidine phospho - transferases) that are typically activated by cytokinins.
«The nematodes could not infect well, and that was a clear piece of evidence suggesting that cytokinin plays a main role in plant - nematode interactions.»
«This shows that if you take away the ability of the plant to recognize cytokinin the worms are unable to fully develop.»

The lab of Florian Grundler at Rheinische Friedrich - Wilhelms - University of Bonn, Germany, was also on a mission to uncover if genes in the nematode controlled cytokinin activation.
«In this case, Heterodera schachtii can not use its ability to produce cytokinin anymore, because a vital pathway was interrupted in the root cells,» explained Dr Siddique.
This Arabidopsis root shows how the beet cyst nematode activates cytokinin signaling in the syncytium 10 days after infection.
Cytokinin normally regulates a plant's shoot growth, leaf aging, and other cell processes.
This implies that a plant hormone like cytokinin is involved, says Mitchum.
«Because these genetically modified plants have cytokinin everywhere and keep producing it, they live on and produce roots when a normal plant would just die.»
«We assume cytokinins are made mainly in the roots of a normal plant, so when you chop off its roots, the plant has lost its supply,» says Meyer.
The team modified Sho to boost cytokinin production and inserted it into potatoes, petunias, and other floral species.
Plants with lower levels of Gn1a have more cytokinin available, which leads to better reproductive development and thus more grains.

But did you know that it contains cytokinins, a type of naturally occurring plant hormone that's been linked to reduced cellular aging in humans?
Peter Meyer, a molecular biologist at the University of Leeds, and his colleagues identified a gene they labeled Sho (for shooting), which controls production of cytokinins, hormones that delay aging in plants.
We previously detailed that PhoB is capable of translocation to the plant nucleus in response to HK activation (by exogenous cytokinin) in a signal - dependent and tissue - independent manner [12].
They discovered that a gene known as Gn1a controls an enzyme that degrades the hormone cytokinin.
Now we know that the nematode is also secreting cytokinin to modulate the pathways.
Possibly the most useful element of coconut water for acne, or rather for your skin's appearance in general, is a little known group of plant compounds called cytokinins.
Hence, the best option is to apply it your face, to inundate your cells with cytokinins and potentially stay young forever.
Another experiment looked at Arabidopsis containing a reporter gene called GUS that was fused to the regulatory sequences of the cytokinin receptor genes.
A final experiment used a mutant that created an excess of an enzyme that degrades cytokinin, finding that a base level of plant cytokinin was also necessary for nematode growth.
«While it's well - known that certain bacteria and some fungi can produce and secrete cytokinin to cause disease, it's not normal for an animal to do this,» said Melissa Mitchum, an MU plant scientist and co-author on the study.
Next, she infected plants missing the majority of their cytokinin receptors with nematodes.
They had identified a key gene in the beet cyst nematode that makes the cytokinin hormone.
While Mitchum's lab had a hunch that cytokinin was key to this takeover, proving it took some creative science.
«The simple statement is that the cytokinin receptors were activated in response to nematode infection and the mutants did not support growth and development of the nematodes,» Mitchum said.
Cytokinin is normally produced in plants, but these researchers determined that this growth hormone is also produced by nematode parasites that use it to take over plant root cells.
«One of the great things about using Arabidopsis as our host plant is the vast genetic resources of cytokinin and hormone mutants that are available through the scientific community,» De La Torre said.
We previously reported that in response to cytokinin - mediated HK activation in plants, the bacterial response regulator PhoB translocates to the nucleus and activates transcription.
We showed that PhoB - VP64 could activate the PlantPho promoter fused to GUS in response to activation of endogenous HKs with exogenous cytokinin.
