CDFD scientist develops mechanism on bio-control of destructive bacteria to the crops

HYDERABAD: In what could be termed as a substitute for Genetically Modified plants, a learn about through scientists of the Centre for DNA Fingerprinting and Diagnostics haS proven that a bio-control approach is used to management Xanthomonas micro organism that has effects on main agricultural and horticultural plants like rice, cabbage, pomegranate, tomato and citrus.
The micro organism is known for inflicting 30 to 50% of damage to the plants.

CDFD body of workers scientist Subhadeep Chatterjee advised TOI that his learn about found that that low-iron situation precipitated the expression of a cluster of disease-causing genes within the micro organism.



“The learn about had proven through easy application of a soluble form of iron within the vegetation suppresses the illness. This will minimise the manufacturing of disease-causing proteins,”

Chatterjee added: "A gaggle of micro organism known as Xanthomonas causes heavy agricultural loss, especially under humid conditions. A analysis is happening to grasp the illness mechanism of Xanthomonas micro organism and to grasp the fundamental means of pathogenicity. We have identified a number of virulence elements in this pathogen including bacterial signalling molecules, motion and attachment, which contribute to the causes of sicknesses. Iron, which is also crucial nutrient for the plant, is the foremost signal which triggers on the pathogen to reason extra sicknesses.”


By converting the iron level under laboratory conditions, the researcher could mimic the illness situation which is encountered through the pathogenic Xanthomonas micro organism when it infects or is available in touch with the plant.


Journal of Environmental Microbiology has approved the learn about, and the analysis paper might be printed quickly.


Chatterjee stated,"Usually, transgenic plants are developed to fight plant sicknesses, and there are huge health protection issues. The bio-control mechanisms like that, in this case, perhaps an effective choice,” Chatterjee stated.


“In future, methods to intervene with the iron availability or bacterial iron metabolism to minimise the manufacturing of disease-causing proteins within the micro organism would possibly lead us to broaden methods to management and scale back the severity of various crop sicknesses led to through Xanthomonas team of micro organism,” he added.
