Interdependency of brassinosteroid and auxin signaling in Arabidopsis.

Nemhauser Jennifer L JL Mockler Todd C TC Chory Joanne J

PLoS biology 20040824 9

How growth regulators provoke context-specific signals is a fundamental question in developmental biology. In plants, both auxin and brassinosteroids (BRs) promote cell expansion, and it was thought that they activated this process through independent mechanisms. In this work, we describe a shared auxin:BR pathway required for seedling growth. Genetic, physiological, and genomic analyses demonstrate that response from one pathway requires the function of the other, and that this interdependence ...[more]

Transcription profiling of 10-day old Arabidopsis seedlings treated for 30, 120 and 240 minutes with the plant hormone indole-3-acetic acid (auxin)Auxin induced effects investigated using bead-purified probe arrays to assess the technology

Project description:21120 Arabidopsis thaliana gene sequence tags were amplified and purified using a novel bead-based strategy (see Publication for more details).This experiment was carried out to demonstrate the use of these arrays for expression profiling of Arabidopsis thaliana.Briefly, 10-day old Arabidopsis seedlings were treated for 30, 120 and 240 minutes with the plant hormone indole-3-acetic acid (auxin) and the effects on gene expression were analysed.

Effect of long-chained auxin conjugates on gene expression in the seedlings of Brassica rapa

Project description:Auxin amino acid conjugates are considered storage forms of auxins available as a source of active auxins on the plant demand. We treated Brassica rapa seedlings with 0.01 mM indole-3-acetyl-L-alanine (IAA-Ala), indole-3-propionyl-L-alanine (IPA-Ala), and indole- 3-butyryl-L-alanine (IBA-Ala) and examined their effects on the transcriptome. All auxin conjugate treatments caused similar patterns in transcription profiles compared to the control, but with different intensities of over- and under-expression depending on the treatment. Most auxin-related DEGs were identified after IBA-Ala treatment, followed by IPA-Ala and IAA-Ala, respectively.

Gene expression analysis in response to various hormone treatments

Project description:Hormones effect various plant developmental processes by altering gene expression. The expression of several genes is regulated by plant hormones and many of these genes are regulated commonly and specifically by various hormones. We used microarrays to study the global effect of plant hormones on rice gene expression and identify the genes involved in operlapping and specific transcriptional responses. Rice seedlings of IR64 variety were grown hydroponically for 7-days in a culture room with a daily photoperiodic cycle of 14h light and 10h dark. Seedlings were incubated in water (control) or 50 ÂµM solution of indole-3-acetic acid (auxin, IAA) and benzyl aminopurine (cytokinin, BAP) and 100 ÂµM solution of abscisic acid (ABA), 1-aminocyclopropane-1-carboxylic acid (ethylene derivative, ACC), salicylic acid (SA) and jasmonic acid (JA) for 3h. The 5 micrograms of total RNA sample isolated from each tissue sample was processed for microarray analysis according to Affymetrix protocol. Two biological replicates for each sample (two controls, IAA, BAP, ABA, ACC, SA and JA) were used for microarray analysis.

Gene expression analysis in wild-type and OsGRX8 overexpression line in response to various treatments

Project description:Glutaredoxins (GRXs) are the ubiquitous oxidoreductase enzymes, which play important role in defense against various stresses. To analyze the function of a CC-type rice GRX gene, OsGRX8, we overexpressed it into Arabidopsis constitutively. The physiological analyses revealed that overexpression of GRX gene enhanced abiotic stress tolerance in transgenic plants as compared to wild-type. We used microarrays to study the global effect of overexpression of OsGRX8 in Arabidopsis under control and various treatments. Wild-type and transgenic Arabidopsis seedlings were grown on MS medium for 14-days in a culture room with a daily photoperiodic cycle of 16h light and 8h dark. Seedlings were incubated in water (control) or 100 ÂµM solution of indole-3-acetic acid (auxin, IAA), 200 mM sodium chloride (salt, NaCl) and 25 ÂµM solution of methyl viologen (MV)for 3h. The 500 ng of total RNA sample isolated from each tissue sample was processed for microarray analysis according to Affymetrix protocol. Two biological replicates for each sample (control, IAA, NaCl and MV) of wild-type and GRX overexpression line were used for microarray analysis.

Expression data from Arabidopsis seedlings upon LRIS using NAA (1-Naphthaleneacetic acid) or non-auxin-like lateral root inducer naxillin

Project description:The acquisition of water and nutrients by plant roots is a fundamental aspect of agriculture and strongly depends on root architecture. Root branching and expansion of the root system is achieved through the development of lateral roots and is to a large extent controlled by the plant hormone auxin. However, the pleiotropic effects of auxin or auxin-like molecules on root systems complicate the study of lateral root development. Here we describe a small-molecule screen in Arabidopsis thaliana that identified naxillin as what is to our knowledge the first non-auxin-like molecule that promotes root branching. By using naxillin as a chemical tool, we identified a new function for root cap-specific conversion of the auxin precursor indole-3-butyric acid into the active auxin indole-3-acetic acid and uncovered the involvement of the root cap in root branching. Delivery of an auxin precursor in peripheral tissues such as the root cap might represent an important mechanism shaping root architecture. To further explore the specificity of naxillin for lateral root development, we compared the early effects of naxillin at the transcriptome level with NAA (1-Naphthaleneacetic acid) in roots of 3-day-old seedlings after 2-h and 6-h treatment. Arabidopsis thaliana (L). Heynh., Col-0 seeds were germinated vertically on solid medium derived from standard MS medium supplemented with 10 μM NPA (1-N-Naphthylphthalamic acid). Three days after germination, plants were transferred to 10 μM NAA (1-Naphthaleneacetic acid) or 50 μM naxillin for 2 and 6 hours. Plants were sampled before (Roots at T0, NPA) or after treatment (Roots at T1 and T2). RNA isolation was performed on 500 root sections (only root without meristems) for each sample. All sampling points were performed in three independent experiments.
