Frontiers | Plant RNA binding proteins for control of RNA virus infection | Frontiers in Plant Physiology

Plant RNA viruses have effective strategies to infect host plants through either direct or indirect interactions with various host proteins, thus suppressing the host immune system.

Nature: miRNAs trigger widespread epigenetically activated siRNAs from transposons in Arabidopsis

Nature: miRNAs trigger widespread epigenetically activated siRNAs from transposons in Arabidopsis | plant science | Scoop.it

"Thus miRNA-directed epigenetically activated’ small interfering RNAs (easiRNA) biogenesis is a latent mechanism that specifically targets transposon transcripts, but only when they are epigenetically reactivated during reprogramming of the germ line. This ancient recognition mechanism may have been retained both by transposons to evade long-term heterochromatic silencing and by their hosts for genome defence.
