GWAS with Heterogeneous Data: Estimating the Fraction of Phenotypic Variation Mediated by Gene Expression Data

G3: Genes, Genomes, Genetics, 2018
Intermediate phenotypes such as gene expression values can be used to elucidate the mechanisms by which genetic variation causes phenotypic variation, but jointly analyzing such heterogeneous data are far from trivial.

Investigating the Association between Flowering Time and Defense in the Arabidopsis thaliana-Fusarium oxysporum Interaction. [PDF]

PLoS ONE, 2015
Plants respond to pathogens either by investing more resources into immunity which is costly to development, or by accelerating reproductive processes such as flowering time to ensure reproduction occurs before the plant succumbs to disease.

The Landscape of Long Non‐Coding RNAs Provides Insights Into the Domestication and Improvement of Pear Fruit

Advanced Science, EarlyView.
This study reveals that long non‐coding RNAs represent important regulatory components underlying pear domestication and improvement. Integrative multi‐omics analyses identify selected lncRNAs associated with fruit traits, while functional validation uncovers a lignin‐related lncRNA, lncRNA‐pys, that promotes lignin accumulation.

Gene Expression Analysis of Deduced Protein Sequence from the FLOWERING LOCUS C (FLC) Homolog during Vegetative and Reproductive Phases in Lepidium sativum L.

Journal of Genetic Resources
The transition of the shoot apical meristem from vegetative to reproductive phases is a critical stage in the plant life cycle. In contrast, the success of reproduction depends on the flowering initiation timing. One of the key repressors of flowering is the gene FLOWERING LOCUS C (FLC), which is important for determining flowering time.

Farm labor scarcity and its uneven impacts on crop producers in the United States

American Journal of Agricultural Economics, EarlyView.
Abstract This study is the first to evaluate the impacts of farm labor scarcity on producers in the United States across different crop production systems. Between 2002 and 2017, we disentangle the effects of labor scarcity from the impacts of rising commodity demand, technological change, and supply of other inputs on labor market outcomes.

Hybrid protein assembly-histone modification mechanism for PRC2-based epigenetic switching and memory

eLife, 2021
The histone modification H3K27me3 plays a central role in Polycomb-mediated epigenetic silencing. H3K27me3 recruits and allosterically activates Polycomb Repressive Complex 2 (PRC2), which adds this modification to nearby histones, providing a read/write

From wild to tamed: Reimagining novel crops through omics and local plant diversity

PLANTS, PEOPLE, PLANET, EarlyView.
The global food system faces growing pressure from climate change, biodiversity loss, and rising nutritional demands. Agriculture has increased yields but reduced crop diversity, flavor, and nutritional quality, leaving societies vulnerable and dependent on a narrow set of staple species.

Unraveling in vitro phase separation and aggregation properties of the structured region of FMRP and the impact of Fragile X syndrome‐linked mutations

The FEBS Journal, EarlyView.
Fragile X messenger ribonucleoprotein 1 (FMRP) is a multidomain RNA‐binding protein associated with Fragile X Syndrome (FXS). We found that its N‐terminal structured region has an intrinsic propensity to undergo liquid–liquid phase separation and fibril formation. FXS‐associated mutations perturb protein stability and aggregation propensity, suggesting

Species-wide gene editing of a flowering regulator reveals hidden phenotypic variation.

PLoS Biology
Genes do not act in isolation, and the effects of a specific variant at one locus can often be greatly modified by polymorphic variants at other loci.

A genetic and molecular analysis of flowering time in Arabidopsis thaliana using natural variation = Een genetische en moleculaire analyse van bloeitijd in Arabidopsis thaliana gebruikmakend van natuurlijke variatie [PDF]

, 2002
The natural allelic variation at flowering time loci between two Arabidopsis thaliana accessions; Landsberg erecta (L er ) and the tropical Cape Verde Island (Cvi) has been analyzed.
