Auxin Action: Slogging out of the Swamp
How does auxin affect so many different aspects of plant growth and development? Recent evidence from localization of auxin efflux carriers and the effects of auxin on degradation of transcription factors has begun to reveal a possible mechanism for auxin action.
متن کاملThe cyclophilin DIAGEOTROPICA has a conserved role in auxin signaling.
Auxin has a fundamental role throughout the life cycle of land plants. Previous studies showed that the tomato cyclophilin DIAGEOTROPICA (DGT) promotes auxin response, but its specific role in auxin signaling remains unknown. We sequenced candidate genes in auxin-insensitive mutants of Physcomitrella patens and identified mutations in highly conserved regions of the moss ortholog of tomato DGT....
متن کاملA Unique Phenotype in Heterozygotes of the Auxin-Insensitive Mutant of Tomato, diageotropica.
Tomato (Lycopersicon esculentum Mill.) plants heterozygous for the diageotropica (dgt) mutation exhibit a unique phenotype, termed ;mottled.' Unlike dgt, mottled individuals grow upright, exhibit normal root branching, and produce normal levels of ethylene in response to applied auxin. Leaves of mottled plants are deformed and reduced in size and are characterized by a mottled appearance on the...
متن کاملCytokinin inhibits a subset of diageotropica-dependent primary auxin responses in tomato.
Many aspects of plant development are regulated by antagonistic interactions between the plant hormones auxin and cytokinin, but the molecular mechanisms of this interaction are not understood. To test whether cytokinin controls plant development through inhibiting an early step in the auxin response pathway, we compared the effects of cytokinin with those of the dgt (diageotropica) mutation, w...
متن کاملThe cyclophilin A DIAGEOTROPICA gene affects auxin transport in both root and shoot to control lateral root formation.
Cyclophilin A is a conserved peptidyl-prolyl cis-trans isomerase (PPIase) best known as the cellular receptor of the immunosuppressant cyclosporine A. Despite significant effort, evidence of developmental functions of cyclophilin A in non-plant systems has remained obscure. Mutations in a tomato (Solanum lycopersicum) cyclophilin A ortholog, DIAGEOTROPICA (DGT), have been shown to abolish the o...
