Global Research Team Discovers How Plant Immunity is TransferredMarch 27, 2019
The researchers identified four DNA loci that control disease resistance against the plant pathogen downy mildew. La Trobe University research fellow Dr. Ritushree Jain said that plants which are repetitively attacked by pathogens develop a ‘memory' (known as priming in plants) of the encounter, enabling them to fight efficiently in future attacks. This transfer of memory to their next generation via seeds is done through DNA methylation, according to Dr. Jain. He added that the process is an epigenetic phenomenon, and there are no changes in the DNA sequence.
