Phenotypic scoring of Canola Blackleg severity using machine learning image analysis

This paper introduces a deep learning model to score Canola Blackleg severity from images, showing it is more consistent than expert raters and maintains similar heritability for breeding purposes.

MDR1 DNA glycosylase regulates the expression of genomically imprinted genes and helitrons

This study shows that MDR1 DNA glycosylase regulates maternally expressed imprinted genes and TEs in endosperm by demethylation, with two-thirds of MEGs showing DNG-dependent regulation.

Conservation of imprinted expression across genotypes is correlated with consistency of imprinting across endosperm development in maize

The paper analyzes imprinted gene expression across multiple time points and genotypes in maize endosperm, finding a correlation between imprinting consistency over time and conservation across genotypes.

Differences in activity and stability drive transposable element variation in tropical and temperate maize.

The paper develops a pan-TE annotation tool to analyze TE variation in maize, finding that tropical maize has more TE sequences due to active and less methylated LTR retrotransposons.

The maize gene maternal derepression of r1 (mdr1) encodes a DNA glycosylase that demethylates DNA and reduces siRNA expression in endosperm

This paper identifies MDR1 as a DNA glycosylase in maize that demethylates DNA and reduces siRNA expression in endosperm, challenging the role of demethylation in transposon repression and genomic imprinting.

Dynamic patterns of transcript abundance of transposable element families in maize

This study characterizes TE family transcript abundance in maize using RNA-seq data from over 800 libraries, revealing dynamic and tissue-specific expression patterns.

Transposable elements contribute to dynamic genome content in maize

The paper identifies variable transposable element (TE) insertions across four maize genomes, showing their role in genome organization and gene content variation.

Hybrid decay: a transgenerational epigenetic decline in vigor and viability triggered in backcross populations of teosinte with maize

The paper describes a transgenerational epigenetic decline in vigor and viability in maize-teosinte backcross populations, termed 'hybrid decay', characterized by genomic instability and altered gene expression.
