Microarray hybridization data from the root tips of 5-day-old Arabidopsis thaliana seedlings grown on tilted, hard agar surfaces

Project description:The growth behavior of plant roots on tilted, hard agar surfaces is determined by many basic cellular processes, including microtubule dynamics and cell wall expansion. Among Arabidopsis thaliana accessions there is natural variation for these behaviors, including one known as skewing or slanting. The root skewing pattern on hard, tilted agar surfaces may be a clue to adaptations of an accession to its environment. Here, we compare expression profiles of two accessions with diverse skewing behavior grown on the wave assay, which consists of seedlings growing two days vertically and 3 days tilted on hard agar plates. Cvi has a strong skew on tilted, hard agar sufaces, and Ler-2 has a weaker one. We also include a near isogenic line, 170G-55-16 a.k.a HGI2.1, that is mostly Ler-2 in background but has a segment of Cvi introgressed into chromosome 2. This line has an intermediate skew between its two parents. 3 biological replicates of each of 3 genotypes (Cvi, Ler-2, and 170G-55-16/HGI2.1) were subjected to the wave assay. After the assay, approximately 600 root tips from each biological replicate were pooled for RNA extraction and hybridization on the Affymetrix ATH1 microarray.

Effect of high temperature on Arabidopsis thaliana root tips

Project description:Plant roots located in the upper soil layers are prone to experience high temperatures. To gain insight into the effect of high temperature on root development and functioning, we exposed five-day-old Arabidopsis thaliana seedlings grown on agar plates to 30 °C for 48 hours, and compared the gene expression profile in the root tip with that from seedlings that remained at 22 °C.

Expression data from roots and first two leaves of tomato seedlings growing on regular MS medium or MS medium supplemented with multi-wall carbon nanotubes (0, 50, 100, 200 ug/ml) or activated carbon (50 mg/ml)

Project description:To investigate effects of carbon nanotubes (CNTs) om total expression profile of tomato plants we introduced CNTs in MS agar medium in concentrationd 0, 50, 100, 200 ug/ml Objectives for this study included the identification of genes that were up or down-regulated at the transcriptional level in tomato seedlings in response to carnom nanotubes (CNTs). 10 day old root tips and first two leaves of wild type tomato seedlings (cv. Micro-Tom) growing on regular MS agar medium or MS medium supplemented with carbon nanotubes (50, 100, 200 ug/ml) or MS medium supplemented with activated carbon (50 ug/ml) were selected for RNA extraction and hybridization on Affymetrix microarrays.

Phosphorus starvation induced genes in Brassica carinata

Project description:The purpose of the present study is to determine the effect of Phosphorus deficiency on gene expression level using microarray analysis to identify genes responsible for root hair development. Phosphorus deficiency induced the formation of root hairs to explore a greater soil volume but molecular mechanisms were unknown. Therefore, microarray experiments were performed using root tips of Brassica carinata cultivars Bale and Bacho, respectively differing in root hair length during Phosphorus deficiency. Experimental design was carried out in nutrient solution in a climate chamber with controlled environmental conditions (20°C, 16h day/8h night cycle, 70% relative humidity) in a randomized design. 25 root tips from 10 day old seedlings grown without Phosphorus of 1cm length were harvested and immediately frozen in liquid nitrogen. Gene expression analyses were performed
