Phenotype

Embryo defective. Embryos not viviparous, cotyledons partially transformed into leaves, embryos sensitive to abscisic acid, some trichomes form on cotyledons after germination; stomata are found on surface of cotyledons of mutant embryos; anthocyanin accumulates in the top half of mutant cotyledons; mutant embryos do not form roots during the first 48 hours of culture; germinating seedlings often appear distorted with elongated hypocotyl and cotyledons curled down; mutant seeds are largely desiccation tolerant, with some reduction of viability after several weeks of storage; maintained as heterozygote.
