Auxin, actin and growth of the Arabidopsis thaliana primary root.
To understand how auxin regulates root growth, we quantified cell division and elemental elongation, and examined actin organization in the primary root of Arabidopsis thaliana. In treatments for 48 h that inhibited root elongation rate by 50%, we find that auxins and auxin-transport inhibitors can be divided into two classes based on their effects on cell division, elongation and actin organiz...
متن کاملNitrate-Regulated Glutaredoxins Control Arabidopsis Primary Root Growth.
Nitrogen is an essential soil nutrient for plants, and lack of nitrogen commonly limits plant growth. Soil nitrogen is typically available to plants in two inorganic forms: nitrate and ammonium. To better understand how nitrate and ammonium differentially affect plant metabolism and development, we performed transcriptional profiling of the shoots of ammonium-supplied and nitrate-supplied Arabi...
متن کاملRoot Hair Growth in Arabidopsis thaliana
We study the factors that affect the root hair growth in the Arabidopsis thaliana plant. From experimental data, we measure how the average velocities of growth and tip shapes of the root hairs are affected by pressure and nutrients. Then using a biomechanical model, we can compute the physical parameters of the root hair and aim to correlate our model with experiments by using image processing...
متن کاملCytokinin signaling in Arabidopsis.
Cytokinins have been implicated in many developmental processes and environmental responses of plants, including leaf senescence, apical dominance, chloroplast development, anthocyanin production, and the regulation of cell division and sink/source relationships. They were identified in the pioneering work of Skoog and Miller (1957) by their ability to promote cell division in cultured cells in...
متن کاملPrimary root growth, tissue expression and co-expression analysis of a receptor kinase mutant in Arabidopsis
There is no functional annotation for the majority of the several hundreds of receptor-like kinases in plants. A direct way of inferring the function of these proteins is to study the phenotype that results from loss of function mutants such as T-DNA mutant lines. In this research a function (phenotype) to At2g37050 gene that encodes a receptor like kinase in Arabidopsis T-DNA line was...
