each meristem will have developed differently, each different flower from each meristem of the same plant will potentially possess different modifications. In contrast to animals, however, plants do not undergo chromatin remodeling between generations, making the maintenance and inheritance of silencing an entirely different process. There are distinct and identifiable mechanisms on the maintenance of transposon inactivation in plants but, unfortunately, there is significantly less information on initiation of said inactivation. Recognition Though the effects of transposition can sometimes manifest phenotypically, and indeed, this effect led to their discovery, transposons can be difficult for the cellular machinery to detect. Many TEs contain stretches of genuine coding DNA, copied from the host, and there is no distinct structure, code, or identifying characteristic of any kind that would allow a cell to recognize the full range of transposable elements with accuracy. Even besides coding for functional proteins or RNAs, some transposons, like class II elements, contain code copied from the nearby strand, allowing them to blend in. Given that the preceding is true, it must be that transposons are recognized more by their effect than their structure. Thus, cell machinery, as detailed in the next section, exists that is capable of detecting transcripts that are atypical of host genomes, such as: Double-stranded RNAs (dsRNAs), which are indicative of both retroviruses and transposons and, more specifically: Small interfering RNAs (siRNAs), which are processed from dsRNA transcribed from inverted repeating elements in the transposon code; a short sense and anti-sense strand are created, which form dsRNA MicroRNAs (miRNAs), which are similar to siRNAs, but have an imperfect base pair complement; these are usually formed as a result of shared complementarity between a transposon and a host gene mRNA transcript Methods of Silencing Silencing of transposon transcripts can vary in completeness of silencing as well as in duration of alteration. Plants employ a number of methods, which range from elimination of transcripts to complete epigenetic silencing. In general, these can be sorted into two 'strategies': Gene silencing#Post-transcriptional gene silencing PTGS], post-transcriptional gene silencing, in which siRNA or miRNA derived from transposon activity are loaded onto an RNA-induced silencing complex (RISC), which cleaves targeted mRNA transcripts Gene silencing#Transcriptional gene silencing TGS], transcriptional gene silencing, in which siRNA transposon transcript is loaded onto an RNA-Directed DNA Methylation complex, which methylates the region of DNA which is reactive to the siRNA used in the complex. This can lead
