Specificity, redundancy and antagonism
among plant small RNA pathways
MicroRNAs (miRNAs) and short interfering RNAs (siRNAs) are involved in a
variety of phenomena that are essential for genome stability, development and
adaptive responses to biotic and abiotic stresses. Their mode of action also is
diverse. They guide DNA elimination during the formation of the macronucleus
in protists and heterochromatin assembly in fungi and plants. They target
endogenous mRNAs for cleavage and translational repression in plants and
animals, and protect both plant and animal cells against virus infection through
an RNA-based immune system. They also control the movement of transposable
elements at the transcriptional and posttranscriptional level in plants
and animals. Here I will present specificities, redundancies and antagonisms
among the various plant small RNA pathways.
