Mutated genes

Locus name Alias Hormone Mutated site Paper description
AT5G13680 ABO1/ELO2 abscisic acid A single nucleotide mutation from G2595(counting from the first putative ATG of the genomic sequence) to A was found in abo1-1 in the third predicted exon of the putative gene. encodes a homolog of saccharomyces cerevisiae Iki3/Elp1/Tot1 and homan I

otherAt higher concertrations of ABA (more than 70uM),abo1-1 leaves showed more anthocyanin pigments, and some cotyledons became chiorotic, which was rarely seen in wild-type plants even at 100uM ABA.The abo1-1 mutation appears to affect only the development a-
Silique/Seed Germination rate-reduced
otherThe postgermination growth of abo1-1 seedling was more impaired than that of the wild type.-
Stress Drought-resistant
otherThe abo1 mutation enhances oxidative stress tolerance.-
