Plants don't have human-kind of immure system. There are other ways to protect plants from diseases. For example, place a disease resistance gene in it through conventional breeding or genetic transformation. dsRNA spray was reportedly used to protect plant diseases too. Pankaj Yadav

It's interesting!

Here is an article mentioned in Science (2019 Aug): "New ‘medicine’ could vaccinate plants against devastating viruses." But, don't expect it works like human being immune system. They discuss the use of siRNA as the "vaccine". " The best siRNA, sprayed on the leaves, protected 90% of the plants, the team reports this month (note: 2019 Aug) in the journal Nucleic Acids Research."

Thank you dear professor Yuan-Yeu Yau , Andrew Paul McKenzie Pegman for interesting answer and appreciation it generate more interest for will further search...

Pankaj Yadav You are welcome!

Pankaj Yadav You can also read this article (with basic answers to your question). Well written. https://theconversation.com/can-we-vaccinate-plants-to-boost-their-immunity-54698

" Animals’ immunity has a distinct advantage over plants’, though. New antibodies are made fresh by human immune cells to recognize new pathogens we might encounter. Plants are stuck with what they’ve got (resistance genes). All the resistance genes they have were passed down from their parents. "

Thank you so much dear professor Yuan-Yeu Yau sure i will go through it.

DearYuan-Yeu_Yau sir, u are right, JAs and salicylic acid mediated singling pathway are mainly related plant resistance, defence etc. Bioagent secret metabolites which play singnificant role in plant growth and defence.

Thanks, dear professor Preeti Sonkar for ypour notable point.

Have a look at this useful RG link.

Please also go through the following attached article entitled "Plant immunization".

Thanks!

Thank you so much dear professor Arvind Singh

Just a summary of some practical experience: Plant immunization (dsRNA, JAs, salicylic acid, etc. ) can be effective in controlled environment (like hydroponic greenhouse). In field, plants have already high level of natural immunization due to low night temperatures, surrounding microorganisms, and effect of a single treatment is not significant enough for practical application. Intensive treatments by chemical elicitors may have too high metabolic cost and finally, will reduce yield and resistance to non-specific pathogens during storage (potato, vegetables, fruits)
