Variation in maize for response to photoperiod is related geographical adaptation the species. Maize possesses homologs of many genes identified as regulators flowering time other species, but their relation natural variation unknown. Candidate gene sequences were mapped four populations created by crossing two temperate inbred lines photoperiod-sensitive tropical inbreds. Whole-genome scans conducted high-density genotyping populations, which phenotyped over 3 years both short- and long-day...

Southern leaf blight (SLB), gray spot (GLS), and northern (NLB) are all important foliar diseases impacting maize production. The objectives of this study were to identify quantitative trait loci (QTL) for resistance these in a recombinant inbred line (RIL) population derived from cross between lines Ki14 B73, evaluate the evidence presence genes or conferring multiple disease (MDR). Each was scored separate trials. Highly significant correlations resistances three found. highest correlation...

We report three developments toward resolving the challenge of apparent basal polytomy neoavian birds. First, we describe improved conditional down-weighting techniques to reduce noise relative signal for deeper divergences and find increased agreement between data sets. Second, present formulae calculating probabilities finding predefined groupings in optimal tree. Finally, a significant increase data: nine new mitochondrial (mt) genomes (the dollarbird, New Zealand kingfisher, great potoo,...

ABSTRACT Plant- and animal-pathogenic bacteria utilize phylogenetically distinct type III secretion systems (T3SS) that produce needle-like injectisomes or pili for the delivery of effector proteins into host cells. Pantoea stewartii subsp. (herein referred to as P. ), causative agent Stewart's bacterial wilt leaf blight maize, carries T3SSs. In addition an Hrc-Hrp T3SS, known be essential maize pathogenesis, has a second T3SS ( island 2 [PSI-2]) is required persistence in its flea beetle...

Abstract BACKGROUND Anthocyanin‐rich blue corn is an emerging specialty crop in the USA . The antioxidant properties of offer health benefits human diet. objectives this study were to identify, characterize and quantify anthocyanins from corn. Hypotheses tested that total anthocyanin content was similar among southwestern US accessions it would vary across locations. It also examined whether different components unique certain genotypes. RESULTS Across all locations accessions, average 0.43...

Maize redness (MR), induced by stolbur phytoplasma (‘Candidatus Phytoplasma solani’, subgroup 16SrXII-A), is characterized midrib, leaf, and stalk reddening abnormal ear development. MR has been reported from Serbia, Romania, Bulgaria for 50 years, recent epiphytotics reduced yields 40 to 90% in South Banat District, Serbia. Potential vectors including leafhoppers planthoppers the order Hemiptera, suborder Auchenorrhyncha, were surveyed MR-affected low-MR-incidence fields, 33 different...

Maize streak, incited by maize streak geminivirus (MSV), is a major disease limiting (Zea mays L.) production over widespread areas of Africa. To understand the genetic basis tolerance to MSV, recombinant inbred lines (RILs) derived from cross MSV tolerant Tzi4 with susceptible Hi34, were evaluated for tolerance. Experiments conducted using controlled leafhopper (Cicadulina spp.) infestation in one glasshouse experiment at Namulonge, Uganda, and two field experiments Centro Internacional de...

Complicated cloning procedures and the high cost of sequencing have inhibited wide application serial analysis gene expression massively parallel signature for genome-wide transcriptome profiling complex genomes. Here we describe a new method called robust 5′-transcript ends (5′-RATE) rapid cost-effective isolation long 5′ transcript (∼80 bp). It consists three major steps including 5′-oligocapping mRNA, NlaIII tag ditag generation, pyrosequencing tags. steps, such as purification...

Four isolectin forms of a seed lectin from mature tepary bean (Phaseolus acutifolius) were isolated using solubility fractionation, affinity chromatography, and high performance liquid chromatography. The subunits are polypeptides with an apparent molecular mass 30,000 daltons. 30 kilodalton produced starting approximately 13 days after flowering subsequently comprise major fraction the proteins found in seed. amino terminus each was determined to be highly homologous that common vulgaris...

Tepary beans, Phaseolus acutifolius A. Gray, were more resistant to feeding by the bean weevil, Acanthoscelides obtectus Say (Coleoptera: Bruchidae), than common vulgaris L. Developmental times longer and mortality percentages greater on all tepary accessions compared with beans. In most cases, emergence rates adult prereproductive dry weights lower versus accessions. The estimated number of adults present after 182 d seed storage was low for high beans may provide a useful germplasm source...

Maize production in sub-Saharan Africa incurs serious losses to epiphytotics of foliar diseases. Quantitative trait loci conditioning partial resistance (rQTL) infection by causal agents gray leaf spot (GLS), northern corn blight (NCLB), and maize streak have been reported. Our objectives were identify simple-sequence repeat (SSR) molecular markers linked consensus rQTL one recently identified associated with GLS, determine their suitability as tools for selection improved host resistance....

Diverse landraces of maize have been cultivated for centuries in the southwestern United States and northern Mexico primarily human food consumption. A striking feature these is wide array kernel colors displayed. Traditional cultivation declining, but blue has received increasing commercial interest due to rising consumer demand unique products with health benefits special culinary uses. We evaluated grain yield, agronomic morphological traits, analyzed biochemical composition five one...

Gray leaf spot (GLS) of maize ( Zea mays L.) caused by Cercospora zeae‐maydis Tehon & E.Y. Daniels, can greatly reduce grain yield in conducive environments worldwide. This study was undertaken to evaluate a novel source resistance C. across macroenvironments and link molecular markers loci selective genotyping. A population 144 F 2:3 progeny lines derived from cross between resistant inbred VO613Y susceptible Pa405 were evaluated at Wooster, OH, USA, Cedara Agricultural Research...
