Visually categorized; based on typical appearance; values 0 (none); 1 (bluish or brownish hue present); from photographs of 3 dried leaves of 3 plants; taken in the UV autofluorescence channel.
Arabidopsis seeds were sterilized with chlorine gas; stratified in tubes at 4 deg. C for three days in the dark and sown into standard soil substrate pre-treated with Confidor to prevent black flies infestation. Plants were grown under controlled long-day conditions (16 hr light; 23 oC/8 hr darkness; 18 oC; relative air humidity 60 %). Three seedlings per genotype were planted into individual pots at the first true leaf stage. Three approximately fingernail-sized mature; non-senescent rosette leaves per plant were collected at the age of 5 weeks (at which point plants of some but not all of the genotypes were beginning to bolt).
