Effects of svp, agl24, ap1, lug, and seu Mutants on Flower Development

Mutant CombinationsPhenotypesReference
svp-41Severe early flowering and normal floral development.Hartmann et al. (2000)
agl24-2Late flowering and normal floral development.Michaels et al. (2003)
agl24 svpSevere early flowering, mild floral defects at 20°C: reduced number of organs, partial homeotic transformation in whorl 1. Strong floral defects at 30°C: reduced number of organs, homeotic transformation in all whorls due to the deregulation of AG and AP3 expression in floral meristem and organ primordia.This study
ap1-12Weak allele, homeotic conversion of sepals into leaves or leaf-like sepals. Few secondary or tertiary flowers are formed in the axil of transformed sepals, reduced number of petals.G. Haughna
agl24 svp ap1-12Strong floral defects at 22°C: homeotic conversion of sepals into staminoid or carpelloid organs, petals completely missing, resemble lug-1 mutant flowers.This study
lug-1Narrow leaves and floral organs, homeotic transformations in whorls 1 and 2, reduction in organ number, deregulation of AG and AP3 expression in floral meristem and floral organ primordia.Liu and Meyerowitz (1995)
seu-1Floral phenotype similar to, but weaker than, lug-1, including narrow leaves and floral organs, homeotic transformations in whorls 1 and 2, organ number reduced in whorls 2 and 3.Franks et al. (2002)
lug seuEnhanced flower phenotype compared with both single mutant plants, reduction in floral organ number and enhanced carpelloidy of whorl 1 organs, whorl 2 organs are completely absent. Deregulation of AG and AP3 expression in floral meristem and floral organ primordia.Franks et al. (2002)
