" By examining the various raw sequence reads, the finisher then makes a judgment call as to the correct base or sends the region back for additional sequencing. In cases where an organism has lost photosynthesis, the plastid genome is typically much reduced in size and coding capacity; occasionally it is lost entirely. Here, we review advances in CRISPR/Cas9 and its variants and examine their applications in plant genome editing and related manipulations. Today, more sophisticated genome‐editing techniques such as CRISPR/dCas9 would allow the non‐random insertion of LacO arrays into the genome. In cases where an organism has lost photosynthesis, the plastid genome is typically much reduced in size and coding capacity; occasionally it is lost entirely. Sequence annotation and analyses 3. Conventional approaches for delivering this DNA include Agrobacterium or biolistics, both of which result in the random integration of one or more copies of the DNA sequence. Although developed recently, it has been established in several important plant species, including rice, wheat, and maize, to introduce agronomically important traits such as heat/cold tolerance, disease resistance, herbicide tolerance, and yield improvement. For all kingdoms, see the list of sequenced genomes.. See also List of sequenced algae genomes Nature biotechnology, 10.1038/nbt1486 Munroe & Harris, 2010.
