Identifying QTLs Related to Grain Filling Using a Doubled Haploid Rice (Oryza sativa L.) Population
Agronomy, 2023 Grain filling is an important trait of rice that affects the yield of grain-oriented crop species with sink capacity-related traits. Here, we used a doubled haploid (DH) population derived from a cross between 93-11 (P1, indica) and Milyang352 (P2 ...

Comparison between instrumental variable and mediation-based methods for reconstructing causal gene networks in yeast [PDF]
Molecular Omics, 2021,17, 241-251, 2020 Causal gene networks model the flow of information within a cell, but reconstructing them from omics data is challenging because correlation does not imply causation. Combining genomics and transcriptomics data from a segregating population allows to orient the direction of causality between gene expression traits using genomic variants.

A hierarchical Bayesian approach to multi-trait clinical quantitative trait locus modeling
Frontiers in Genetics, 2012 Recent advances in high-throughput genotyping and transcript profiling technologies have enabled the inexpensive production of genome-wide dense marker maps in tandem with huge amounts of expression profiles.

Downy mildew resistance and genetic variability in a wild rocket germplasm collection
Agronomy Journal, Volume 114, Issue 6, Page 3083-3095, November/December 2022., 2022 Abstract One hundred accessions of a “core collection” of Diplotaxis tenuifolia (L.) DC. and Eruca spp. were screened at seedling stage for resistance to downy mildew. Accessions tested at the seedling stage were assigned to 0–6 interaction phenotypes.

Bayesian Method for Disease QTL Detection and Mapping, using a Case and Control Design and DNA Pooling [PDF]
Biostatistics (2007) 8:546--565, 2005 This paper describes a Bayesian statistical method for determining the genetic basis of a complex genetic trait. The method uses a sample of unrelated individuals classified into two groups, for example cases and controls. Each group is assumed to have been genotyped at a battery of marker loci using a laboratory effort efficient technique called DNA ...

Does agroecosystem management mitigate historic climate impacts on dryland winter wheat yields?
Agronomy Journal, Volume 114, Issue 6, Page 3515-3530, November/December 2022., 2022 Abstract Global studies that quantify climate effects on crop yields using top‐down spatial frameworks are invaluable for assessing generalized effects on world food supplies, yet do not contain the resolution necessary to identify local mediating effects of management. Our objectives were to identify (a) what climate factors have historically affected

The Genetic Structures and Molecular Mechanisms Underlying Ear Traits in Maize (Zea mays L.)
Cells, 2023 Maize (Zea mays L.) is one of the world’s staple food crops. In order to feed the growing world population, improving maize yield is a top priority for breeding programs. Ear traits are important determinants of maize yield, and are mostly quantitatively

American Journal of Botany, Volume 109, Issue 12, Page 1991-2005, December 2022., 2022 Abstract Premise Numerous processes influence plant distributions and co‐occurrence patterns, including ecological sorting, limiting similarity, and stochastic effects. To discriminate among these processes and determine the spatial scales at which they operate, we investigated how functional traits and phylogenetic relatedness influence the ...

Simulated ecology-driven sympatric speciation [PDF]
Physical Review E, 64, 021906(1-6) (Aug 2001), 2000 We introduce a multi-locus genetically acquired phenotype, submitted to mutations and with selective value, in an age-structured model for biological aging. This phenotype describes a single-trait effect of the environment on an individual, and we study the resulting distribution of this trait among the population.
