Identification of stably expressed QTL for resistance to black shank disease in tobacco (Nicotiana tabacum L.) line Beinhart 1000-1

Crop Journal, 2018
Cigar line Beinhart 1000-1 has effective durable resistance to black shank (BS) and is considered one of the most resistant sources in tobacco (Nicotiana tabacum L.).

Transcriptomic profiling of wheat near-isogenic lines reveals candidate genes on chromosome 3A for pre-harvest sprouting resistance

BMC Plant Biology, 2021
Background Pre-harvest sprouting (PHS) in wheat can cause severe damage to both grain yield and quality. Resistance to PHS is a quantitative trait controlled by many genes located across all 21 wheat chromosomes.

Identifying PDAP1 as a Biological Target on Human Longevity: Integration of Mendelian Randomization, Cohort, and Cell Experiments Validation Study

Aging Cell, EarlyView.
Integration of multi‐omics analyses reveals PDAP1 as one of the key regulators of longevity and aging. Mendelian randomization, colocalization, prospective studies, and in vitro experiments highlight PDAP1's effects on mortality, lifespan, and cellular senescence.

A complete classification of epistatic two-locus models [PDF]

arXiv, 2006
The study of epistasis is of great importance in statistical genetics in fields such as linkage and association analysis and QTL mapping. In an effort to classify the types of epistasis in the case of two biallelic loci Li and Reich listed and described all models in the simplest case of 0/1 penetrance values.

Increased pericarp cell length underlies a major quantitative trait locus for grain weight in hexaploid wheat.

New Phytologist, 2017
Crop yields must increase to address food insecurity. Grain weight, determined by grain length and width, is an important yield component, but our understanding of the underlying genes and mechanisms is limited.

Estimating Effects and Making Predictions from Genome-Wide Marker Data [PDF]

, 2009
In genome-wide association studies (GWAS), hundreds of thousands of genetic markers (SNPs) are tested for association with a trait or phenotype. Reported effects tend to be larger in magnitude than the true effects of these markers, the so-called ...

How data or error covariance can change and still retain BLUEs as well as their covariance or the sum of squares of errors

Australian &New Zealand Journal of Statistics, EarlyView.
Summary Misspecification of the error covariance in linear models usually leads to incorrect inference and conclusions. We consider two linear models, A$$ \mathcal{A} $$ and B$$ \mathcal{B} $$, with the same design matrix but different error covariance matrices. The conditions under which every representation of the best linear unbiased estimator (BLUE)

Quantitative Trait Locus Mapping of Flowering Time and Maturity in Soybean Using Next-Generation Sequencing-Based Analysis

Frontiers in Plant Science, 2018
Soybean (Glycine max L.) is a major legume crop that is mainly distributed in temperate regions. The adaptability of soybean to grow at relatively high latitudes is attributed to natural variations in major genes and quantitative trait loci (QTLs) that ...

Reversibility of sex changes in the plant kingdom: more important than we thought?

Biological Reviews, EarlyView.
ABSTRACT Compared to animals, plants show a wide range of reproductive strategies with different degrees of sex separation (e.g. dioecy, monoecy, hermaphroditism). While sex expression was previously thought to be genetically determined and fixed in plants, accumulating evidence suggests that sex expression can change reversibly even within one ...
