The early leaf death phenotype in old3-1 mutant plants. a) Representative 21-day-old soil-grown wild type (Ler-0), old3-1 homozygous and old3-1 heterozygous plants grown in standard conditions at 21°C. b) Chlorophyll content and ion leakage of cotyledons from Ler-0 and old3-1 homozygous plants grown for up to 25 days. Each data point is shown as mean ± sd from 4 replicates.
