Phenotype information

Organ AttributeNo hormoneabscisic acid
Hypocotyl/Stem Hypocotyl lengthlong hypocotyls in the dark; longer than 5ptase1-1and 5ptase2-1and 5ptase2-1 5ptase1-.-
otherThe elongation rate of the hypocotyl from 37 to 48 h is significantly increased in this mutant as compared to the 5ptase1-1 and 5ptase2-1 mutants.-
Silique/Seed Germination rateby 18 h there was a significant increase in the germination rate as compared to the wild-type after stratified for 3days at 4℃ and grown in the dark.hypersensitive to small amounts of ABA.
othercontain an increase in Ins(1,4,5)P3 as compared to wild-type seedling.-
