UTR, untranslated region.

^aGermplasm starting with “SALK” are from the Salk Institute collections, while SAIL mutants originate from Syngenta. All lines are ecotype Colubmia-0, except clpd, which was Columbia-3.

^bThis mutant was originally isolated and described by Rudella et al. (2006).

^cPreviously named clpc1-1 in Sjögren et al. (2004), and hsp93-V-2 in Kovacheva et al (2005)

^dPreviously named hsp93-III-1 in Kovacheva et al (2007)
