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
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 ...
The Image of Palestine in the Narratives of Refugees: A Comparative Study of Two Refugee Camps - Qalandia in Palestine and Al Yarmouk in Syria
(Ibrahim Abu-Lughud Institute of International Studies, Birzeit University, 2011)
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
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 ...
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 ...
