The occurrence of radiocesium in food has raised sharp health concerns after nuclear accidents. Despite being present at low concentrations contaminated soils (below μm), cesium (Cs+ ) can be taken up by crops and transported to their edible parts. This plant capacity take Cs+ from notably affected the production rice (Oryza sativa L.) Japan accident Fukushima 2011. Several strategies have been put into practice reduce content this crop species such as soil removal or adaptation agricultural...
Summary A library of 29 482 T‐DNA enhancer trap lines has been generated in rice cv. Nipponbare. The regions flanking the left border from first 12 707 primary transformants were systematically isolated by adapter anchor PCR and sequenced. survey 7480 genomic sequences larger than 30 bp (average length 250 bp), representing 56.4% total readable matching bacterial artificial chromosome/phage chromosome (BAC/PAC) assembled pseudomolecules allowed assigning 6645 (88.8%) insertion sites to at...
Abstract Plant roots have a large range of functions, including acquisition water and nutrients, as well structural support. Dissecting the genetic molecular mechanisms controlling rice root development is critical for new ideotypes that are better adapted to adverse conditions production sustainably achieved yield potential. Most knowledge regarding gene networks involved in has been accumulated model dicotyledon plant species Arabidopsis thaliana . Rice, monocotyledon species, presents...
Here we report on the characterization of rice osa-miR827 and its two target genes, OsSPX-MFS1 OsSPX-MFS2, which encode SPX-MFS proteins predicted to be implicated in phosphate (Pi) sensing or transport. We first show by Northern blot analysis that is strongly induced Pi starvation both shoots roots. Hybridization situ confirms strong induction starvation, with signals concentrated mesophyll, epidermis ground tissues In parallel, analyzed responses OsSPX-MFS2 gene targets starvation. mRNA...
Root traits such as root angle and hair length influence resource acquisition particularly for immobile nutrients like phosphorus (P). Here, we attempted to modify in rice by disrupting the OsAUX1 auxin influx transporter gene an effort improve P efficiency. We show X-ray microCT imaging that is altered osaux1 mutant, causing preferential foraging top soil where normally accumulates, yet surprisingly, efficiency does not improve. Through closer investigation, reveal also promotes elongation...
Abstract Fruit ripening and abscission are associated with an ethylene burst in several melon (Cucumis melo) genotypes. In cantaloupe as other climacteric fruit, exogenous can prematurely induce abscission, production, ripening. Melon genotypes without fruit or also exist are, therefore, non-climacteric. the nonabscising PI 161375, failed to stimulate loss of firmness, expression all target genes tested. However, 161375 etiolated seedlings displayed usual ethylene-induced triple response....
GreenPhylDB is a database designed for comparative and functional genomics based on complete genomes. Version 2 now contains sixteen full genomes of members the plantae kingdom, ranging from algae to angiosperms, automatically clustered into gene families. Gene families are manually annotated then analyzed phylogenetically in order elucidate orthologous paralogous relationships. The offers various lists including plant, phylum species specific For each cluster or family, easy access...
Significance In nature, nearly all plants have only a single layer of endodermis. The number cortex cell layers often varies between species and roots on the same plant. Here we show that expression conserved SHORT-ROOT (SHR) protein, in context root Arabidopsis thaliana, is responsible for determining function extent SHR movement. These results provide plausible model regulating plant relies upon controlled intercellular movement transcription factor.
The hormone auxin is critical for many plant developmental processes. Unlike the model eudicot Arabidopsis (Arabidopsis thaliana), distribution and signaling in rice tissues has not been systematically investigated due to absence of suitable response reporters. In this study we observed conservation components between monocot crop (Oryza sativa), generated complementary types biosensor constructs, one derived from Aux/IAA-based DII-VENUS but constitutively driven by maize ubiquitin-1...
Abstract Rice production faces the challenge to be enhanced by 50% year 2030 meet growth of population in rice-eating countries. Whereas yield cereal crops tend reach plateaus and a is likely deeply affected climate instability resource scarcity coming decades, building rice cultivars harboring root systems that can maintain performance capturing water nutrient resources unevenly distributed major breeding target. Taking advantage gathering community biologists Global Science Partnership...
Salinity tolerance is an important quality for European rice grown in river deltas. We evaluated the salinity of a panel 235 temperate japonica accessions genotyped with 30,000 SNP markers. The was exposed to mild salt stress (50 mM NaCl; conductivity 6 dS m-1) at seedling stage. Eight different root and shoot growth parameters were measured both control stressed treatments. Na+ K+ mass fractions plants using atomic absorption spectroscopy. treatment affected plant growth, particularly...
GreenPhylDB (http://greenphyl.cirad.fr) is a comprehensive platform designed to facilitate comparative functional genomics in Oryza sativa and Arabidopsis thaliana genomes. The main functions of are assign O. A. sequences gene families using semi-automatic clustering procedure create 'orthologous' groups phylogenomic approach. To date, comprises the most complete list plant families, which have been manually curated (6421 families). also contains all relationships computed for 4375 families....
Insertional mutant databases containing Flanking Sequence Tags (FSTs) are becoming key resources for plant functional genomics. We have developed OryGenesDB (http://orygenesdb.cirad.fr/), a database dedicated to rice reverse genetics. Insertion mutants of genes catalogued by Tag (FST) information that can be readily accessed this database. Our presently contains 44166 FSTs generated most the insertional mutagenesis projects. The genome browser is based on powerful Generic Genome Browser...
To organize data resulting from the phenotypic characterization of a library 30 000 T-DNA enhancer trap (ET) insertion lines rice ( Oryza sativa L cv. Nipponbare), we developed Tag Line (OTL) database http://urgi.versailles.inra.fr/OryzaTagLine /). OTL structure facilitates forward genetic search for specific phenotypes, putatively gene disruption, and/or GUSA or GFP reporter expression patterns, reflecting ET-mediated endogenous detection. In latest version, gathers detailed...
Plant leucine-rich repeat receptor-like kinases (LRR-RLKs) are receptor that contain LRRs in their extracellular domain. In the last 15 years, many research groups have demonstrated major roles played by LRR-RLKs plants during almost all developmental processes throughout life of plant and defense/resistance against a large range pathogens. Recently, breakthrough has been made this field challenges dogma specificity LRR-RLKs. We analyzed ~1000 complete genomes show LRR-RK genes now...
A new linkage map of Cucumis melo, derived from the F 2 progeny a cross between PI 414723 and C. melo 'TopMark' is presented. The spans total 1421 cM includes 179 points consisting random amplified polymorphic DNA (RAPD), fragment length polymorphism (AFLP), inter-simple sequence repeats (ISSRs), simple (SSRs), restriction (RFLP) markers. also an aphid resistance trait (Vat) sex type gene, andromonoecious (a), two which are important in breeding control hybrid seed production, as well...
Plant root systems play a major role in anchoring and water nutrient uptake from the soil. The cone angle is an important parameter of system architecture because, combined with depth, it helps to determine volume soil explored by plant. Two genes, DRO1 SOR1, several QTLs for have been discovered last 5 years.To find other linked angle, genome-wide association mapping study was conducted on two panels 162 indica 169 japonica rice accessions genotyped sets SNP markers...
