Mercury toxicity in barley roots

(Submitter supplied) The effects of mercury (HgCl2) on barley (Hordeum vulgare L.) growth, physiological traits and gene expression profiles were studied. The shoot to root ratio was decreased in the two levels of HgCl2 (500 and 1000 μM) assayed, which was related primarily with decreases in shoot dry weight. Moreover stomatal conductance was limited and leaf carbon isotope discrimination decreased. Therefore water uptake limitations seem to be an important component of barley responses to HgCl2. more...

Identification of genes expressed in maize root cortical cells during lysigenous aerenchyma formation using laser microdissection and microarray analyses

(Submitter supplied) Aerenchyma is a specialized tissue consisting of longitudinal gas spaces, which enables internal movement of gases (e.g., O2, CO2, ethylene and methane), in plant roots, petioles and stems. Especially, internal transport of oxygen via aerenchyma from shoots to roots is very important for adaptation or survival of plants under waterlogged condition. To identify aerenchyma formation-associated genes expressed in maize root, we used LM combined with a microarray for monitoring genes expressed in root cortical cells under three conditions: under aerobic condition and under waterlogged condition with and without pretreatment with 1-MCP, an inhibitor of ethylene perception.

Transcriptional characterization of maize roots in response to urea and nitrate

(Submitter supplied) Although urea is the most used nitrogen fertilizer worldwide, little is known on the capacity of crop plants to use urea per se as a nitrogen source for development and growth. To date, the molecular and physiological bases of its transport have been investigated only in a limited number of species. In particular, up to date only one study reported the transcriptomic modulation induced by urea treatment in the model plant Arabidopsis (Mérigout et al., 2008 doi: 10.1104/pp.108.119339). more...

Transcriptome analyses of narrow sheath shoot apical meristem (SAM) vs non-mutant SAM

(Submitter supplied) Loss of function mutations in the narrow sheath (ns) duplicate genes (ns1 and ns2) cause the deletion of a mediolateral domain from maize leaves. The ns genes encode duplicate WUSCHEL1-like homeobox (WOX) putative transcription factors that function redundantly and non-cell autonomously to direct recruitment of leaf founder cell-initials in a lateral domain of the shoot apex. In order to investigate the genetic mechanisms of NS1 gene function, SAM-specific transcriptional profiling of narrow sheath mutant1-R comparing to that of nonmutant using laser microdissection microarray. more...

Nitrogen-efficient rice over-expressing alanine aminotransferase

(Submitter supplied) Oryza sativa cv. Nipponbare was engineered to over-express a barley alanine aminotransferase (alaAT) gene using the promoter (OsANT1) from a rice aldehyde dehydrogenase gene that expresses in roots. We are using biotechnology to improve the nitrogen use efficiency of rice by over-expressing alaAT in a tissue specific (root) manner. The AlaAT enzyme is a reversible aminotransferase that is linked to both C and N metabolism since it uses pyruvate plus glutamate to produce alanine and 2-oxoglutarate, and visa versa.

Responses of Zea mays root tissue to inoculation with the necrotrophic root pathogen Phytophthora cinnamomi

(Submitter supplied) Phytophthora cinnamomi is a devastating soil-borne oomycete with a very broad host range however there remains a major gap in the understanding of plant resistance responses to the pathogen, furthermore, necrotrophic plant-pathogen interactions, particularly those of root pathogens, remain poorly understood. Zea mays exhibits non-host resistance to the pathogen and has been well characterised as a model species. more...

Global transcriptome analysis of two ameiotic1 alleles in maize anthers: defining steps in meiotic entry and progression through prophase

(Submitter supplied) This study compared the transcriptomes of maize anthers at both 1mm and 1.5mm lengths from male sterile mutants with either the am1-489 or am1-pra alleles as well as from fertile siblings of the mutant plants. Comparisons were done varying just the stage (1mm vs 1.5 mm), just the allele (am1-pra vs am1-489 at the same stage), and wild-type vs mutant (same stage and allele). Genes were categorized as On (expressed) or Off (not detected) and if both channels produced an intensity, the differential expression was determined. more...

Transcriptomic changes in maize roots in response to Fe deficiency

(Submitter supplied) Iron deficiency is a yield-limiting factor and a worldwide problem for crop production in many agricultural regions, particularly in aerobic and calcareous soils. Graminaceous species, like maize, improve Fe acquisition through the release of phytosiderophores (PS) into the rhizosphere and the following uptake of Fe(III)-PS complexes through specific transporters. Transcriptional profile obtained by roots 12-d-old maize plants under Fe starvation for 1 week (Fe-deficient; 19-d-old plants) were compared with the transcriptional profile obtained by roots of 12-d-old maize plants grown in a nutrient solution containing 100 μM Fe-EDTA for 1 week (Fe-sufficient; 19-d-old plants).
