Project description:Project : Sugar-Auxine_Rose ngs2017_11_rosex2-auxin sugar antagonist effect on budburst Study of the antagonistic effect between sugar and auxin on the bud burst of the axillary bud of the rose bush - Identification of the molecular network involved in the antagonistic effect between sugar and auxin on the budburst of the vegetative budworm of the rose bush
Project description:Expression data after flg22 treatment on leaf discs in Col-0, 35S:AFB1 and 35S:miR393 We used microarrays to investigated the effect of auxin signaling on flg22 response pathway. We also compared if addition of auxin could simulated the 35S:AFB1 phenotype. Keywords: stress response, disease state analysis

We also compared if addition of auxin could simulated the 35S:AFB1 phenotype. Keywords: stress response, disease state analysis Leaf discs were taken and let overnight in water to avoid the wound response. We then performed the treatment (flg22, flg22 from Agrobacterium tumefaciens, flg22 +NAA, NAA) to the media. The samples where harvested and freeze in liquid nitrogen at 0, 1 and 2h after treatment.

Project description:Proper functioning of the nuclear auxin pathway is essential for regulating plant growth and development by maintaining auxin homeostasis. To understand better physiological mechanisms involved in auxin signaling pathways we investigated the localization and effect of accumulation of auxin coreceptor IAA17/AXR3 in root. We demonstrate that the accumulation of stable nuclear AXR3-1 protein interferes with auxin homeostasis, causing auxin insensitivity and increased rapid root cell elongation followed by detained growth. This growth pattern is associated with changes in phytohormone gene expression. Data from transcriptomic screen combined with reporter lines and mutant studies declare essential role of auxin homeostasis in maintaining optimal root growth rate and development. We proposed a model in which rapid cell elongation is caused by combination of AXR3-1-dependent auxin insensitivity associated with unblocked gibberellin effect on root. This study demonstrate that plants coordinate gibberellin homeostasis by the auxin signaling pathway, contributing to avoid excessive root elongation.
