Project description:Gene expression profiling in soybean under aluminum stress: mechanisms of magnesium amelioration of aluminum toxicity at gene expression level. Micro-molar concentrations of magnesium in culture solution has been shown to ameliorate Al toxicity in soybean and other leguminous species. Different theories have been proposed to explain the chemical mechanisms of how the two ions interact to neutralize the toxic effect of aluminum in the plant root system. To understand the molecular mechanisms of the phenomenon at the gene expression level in soybean, we undertook a comparative transcriptome analysis in Al-tolerant and Al-sensitive genotypes treated with aluminum alone or aluminum plus magnesium using DNA microarrays. The results revealed magnesium enhances Al-tolerance level in the Al-tolerant genotype by down-regulating genes commonly induced in response to Al toxicity. We hypothesized that the magnesium-mediated alleviation of Al toxicity in the Al-tolerant genotype emanates from reduction in energy expenditure of gene expression induced in response to Al stress. Conversely, magnesium appears to ameliorate Al toxicity in the sensitive genotype by dual mechanisms of increasing the expression level of several genes involved in Al-tolerance and decreasing the expression level of most genes. Keywords: Soybean, aluminum toxicity, magnesium, transcriptome Two genotypes: PI 416937 (p) and Young (y); two treatments: Aluminum (Al) or Al+magnesium (Mg); two time points: 12 and 72 hrs; 3 replicates.

Project description:Aluminum (Al) toxicity in plants is one of the primary constraints in crop production. Al³⁺, the most toxic form of Al, is released into soil under acidic conditions and causes extensive damage to plants, especially in the roots. In rice, Al tolerance requires the ASR5 gene, but the molecular function of ASR5 has remained unknown. This data establish a comparative study of miRNAome profiles in ASR5 knockdown rice plants (ssp. Japonica cv. Nipponbare) under Al stress conditions.

Project description:Aluminum toxicity is one of the major limiting factors for many crops worldwide. The primary symptom of Al toxicity syndrome is the inhibition of root growth, leading to poor water and nutrient absorption. The causes of this inhibition are still elusive, with several biochemical pathways being affected and with a significant variation between species. Most of the work done so far to investigate the genes responsible for Al tolerance used hydroponic culture. Here we evaluated plant responses using soil as substrate, which is a condition closer to the field reality. We used Affymetrix chips to reveal the transcriptional changes of two maize genotypes contrasting for Al tolerance.

We used Affymetrix chips to reveal the transcriptional changes of two maize genotypes contrasting for Al tolerance. Leaves from Cat100-6 (Al-tolerant) and S1587-17 (Al-sensitive) maize genotypes were harvested after growing on acid or control soil for 3 days. Total RNA was extracted and hybridized to Affymetrix GeneChip Maize Genome Array. Three biological replicates were used for each sample.
