Variation for N uptake system in maize: genotypic response to N supply
An understanding of the adaptations made by plants in their nitrogen (N) uptake systems in response to reduced N supply is important to the development of cereals with enhanced N uptake efficiency (NUpE). Twenty seven ...
Heat susceptibility of grain filling in wheat (Triticum aestivum L.) linked with rapid chlorophyll loss during a 3-day heat treatment
Brief heat events (1–3 days, >30 °C) commonly reduce wheat (Triticum aestivum L.) grain size and consequently yield. To identify mechanisms of tolerance to such short heat events, 36 wheat genotypes were treated under ...
Variation in shoot tolerance mechanisms not related to ion toxicity in barley
Soil salinity can severely reduce crop growth and yield. Many studies have investigated salinity tolerance mechanisms in cereals using phenotypes that are relatively easy to measure. The majority of these studies measured ...
Differential expression of BRCC2, a novel BH3-like domain-containing apoptotic molecule, in ductal versus lobular breast carcinoma
(American Association for Cancer Research, 2007)
Background: BRCC2 (breast cancer cell 2) gene was discovered as an approximately 1.2 kb transcript in MDA-MB 231 human breast cancer cells (GenBank accession numbers AF220061 and AF303179). BRCC2 is a 12 kDa cytosolic ...
A simulation study to assess a variable selection method for selecting single nucleotide polymorphisms associated with disease
(Mary Ann Liebert, Inc. 140 Huguenot Street, 3rd Floor New Rochelle, NY 10801 USA, 2012)
In genome-wide association studies, where hundreds of thousands of single nucleotide polymorphisms (SNPs) are genotyped, the potential for false positives is high and methods for selecting models with only a few SNPs are ...
Optimal designs for contingent response models with application to toxicity–efficacy studies
(Springer Science & Business Media, 2012)
We describe a general family of contingent response models. These models have ternary outcomes constructed from two Bernoulli outcomes, where one outcome is only observed if the other outcome is positive. This family is ...
Mapping of novel salt tolerance QTL in an Excalibur× Kukri doubled haploid wheat population
Novel QTL for salinity tolerance traits have been detected using non-destructive and destructive phenotyping in bread wheat and were shown to be linked to improvements in yield in saline fields. Abstract Soil salinity ...
A QTL on the short arm of wheat (Triticum aestivum L.) chromosome 3B affects the stability of grain weight in plants exposed to a brief heat shock early in grain filling
(BioMed Central, 2016)
Background: Molecular markers and knowledge of traits associated with heat tolerance are likely to provide breeders with a more efficient means of selecting wheat varieties able to maintain grain size after heat waves during ...
Optimal designs for contingent response models
We study D- and c-optimal designs for the contingent response models of (1995). In the contingent response model there are two types of failure. We call one failure type toxicity and the other disease failure. No toxicity ...
Planting the Seeds to Overcome Uprooting: A Study of the Forced Transformations in the Palestinian Peasant’s Life
