Analyses of cell type-specific data show that the maternal alleles of genes related to establishing and breaking seed dormancy are suppressed by different combinations of epigenetic marks in the endosperm of Arabidopsis.
Models of plant behaviour show that flowering early in a warming world is an adaptive strategy to insulate progeny seed behaviour from the affects of climate change.

A genomic imprinting program in the endosperm of Arabidopsis mature seeds is dynamically adjusted according to seed dormancy levels and regulates germination.

Natural variation for an adaptively important life history trait is largely due to variation at a single, major-effect locus with multiple alleles, demonstrating that not all complex traits are massively polygenic.

Seed-specific and cold-induced DNA methylation is deposited in the seed progeny to form a transient and transgenerational memory of past environmental conditions to optimize seed germination timing.

Transitions from outcrossing to selfing, a major shift in mating systems, create a specific signature in intra-specific genetic polymorphisms, which can be used to infer the demographic history of populations and acquire valuable insights about the evolution of recombination rates.

Arabidopsis shows extensive genetic diversity in germination time distributions, which can be explained by the underlying ABA/GA network functioning as a noisy bistable switch.

Extending the period of remission for cancer patients requires new knowledge of dormant, residual disease and Netrin signaling contributes to the survival of dormant cells in ovarian cancer.
