Reprogramming of DNA methylation in pollen guides epigenetic inheritance via small RNA.

abstract：:Based on the above mechanisms of mRNA degradation, an integrated model of mRNA turnover can be proposed (Figure 1). In this model, all polyadenylated mRNAs would be degraded by the deadenylation-dependent pathway at some rate. In addition to this default pathway, another layer of complexity would come from degradation...
