Combining field performance with controlled environment plant imaging to identify the genetic control of growth and transpiration underlying yield response to water-deficit stress in wheat
(2015-07-15)
Crop yield in low-rainfall environments is a complex trait under multigenic control that shows significant genotype×environment (G×E) interaction. One way to understand and track this trait is to link physiological studies ...
Optimal designs for dose-finding in contingent response models
(University of Missouri--Columbia, 2004-12)
We study D- and c-optimal designs for dose-finding with opposing failure functions. In particular, we study the contingent response models of Li, Durham and Flournoy (1995). In the contingent response model, there are two ...
Accounting for variation in designing greenhouse experiments with special reference to greenhouses containing plants on conveyor systems
(BioMed Central, 2013)
Background: There are a number of unresolved issues in the design of experiments in greenhouses. They include
whether statistical designs should be used and, if so, which designs should be used. Also, are there
thigmomorphogenic ...
Optimal designs for contingent response models with application to toxicity and efficacy
(Issac Newton Institute for Mathematical Sciences, 2011-12)
We generalize results in the literature to obtain a general family contingent response
models. These models have ternary outcomes constructed from two Bernouli outcomes,
where one outcome is only observed if the other ...
Variation for N uptake system in maize: genotypic response to N supply
(Frontiers, 2015)
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
(Springer, 2016)
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
(CSIRO, 2017)
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 ...
