Editing Arabidopsis thaliana (section)

====Non-Mendelian inheritance controversy====
In 2005, scientists at [[Purdue University]] proposed that ''A. thaliana'' possessed an alternative to previously known mechanisms of [[DNA repair]], producing an unusual pattern of [[Mendelian inheritance|inheritance]], but the phenomenon observed (reversion of mutant copies of the ''[[HOTHEAD (gene)|HOTHEAD]]'' gene to a wild-type state) was later suggested to be an artifact because the mutants show increased outcrossing due to organ fusion.<ref>{{cite journal |vauthors=Lolle SJ, Victor JL, Young JM, Pruitt RE |title=Genome-wide non-mendelian inheritance of extra-genomic information in Arabidopsis |journal=Nature |volume=434 |issue=7032 |pages=505–9 |date=March 2005 |pmid=15785770 |doi=10.1038/nature03380 |bibcode=2005Natur.434..505L |s2cid=1352368}}[https://www.washingtonpost.com/wp-dyn/articles/A58349-2005Mar22_2.html Washington Post summary.] {{Webarchive |url=https://web.archive.org/web/20161118043014/http://www.washingtonpost.com/wp-dyn/articles/A58349-2005Mar22_2.html |date=18 November 2016 }}</ref><ref>{{cite journal |vauthors=Peng P, Chan SW, Shah GA, Jacobsen SE |title=Plant genetics: increased outcrossing in hothead mutants |journal=Nature |volume=443 |issue=7110 |pages=E8; discussion E8–9 |date=September 2006 |pmid=17006468 |doi=10.1038/nature05251 |bibcode=2006Natur.443E...8P |s2cid=4420979 |doi-access=free}}</ref><ref>{{cite journal |vauthors=Pennisi E |author-link=Elizabeth Pennisi |title=Genetics.
