Plant Variegation (or sectoring)
- often genetic but can be other causes

Genome Instability and Transposons
DNA elements capable of moving ("transposing") to new
sites in their genome.
Plant Mt mRNAs & RNA Editing
1. mRNAs are not polyadenylated or capped
2. As in plastids, the 3 ends of Mt mRNAs are
established by processing at the stem-loops
(IRs in DNA) after transcription.
3. Most pre-mRNAs are edited .
