Phenotype information

Organ AttributeNo hormoneabscisic acid
Hypocotyl/Stem Hypocotyl lengthlong hypocotyls in the dark-
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, the decrease in seed germination is not as great as that of the other 5ptase mutants.
other5ptase1-1 mutant seed contained a 2- and 1.4- fold increase in ABA levels in dry and 72-h imbibed seeds as compared to similarly treated wild-type seed; contain an increase in Ins(1,4,5)P3 as conpared to wild-type seedling.-
