California's vernal‐pool mousetails (Myosurus, Ranunculaceae): Phylogenetic analysis of ddRADseq data, hybridization tests, and species delimitation

open access: yesJournal of Systematics and Evolution, EarlyView.
We present the first phylogenetic analysis of the Californian species of Myosurus. Our ddRADseq analysis reveals considerably more diversity than what was recognized in recent floristic treatments. Myosurus minimus subsp. apus was found to be a rare species restricted to Southern California and northwestern Baja California.

Phenotypic plasticity is broadly adaptive across an elevation gradient in the Cutleaf Monkeyflower

open access: yesNew Phytologist, EarlyView.
Leaf shape plasticity expression is variable in Mimulus laciniatus. Summary Phenotypic plasticity is a key mechanism by which organisms cope with environmental heterogeneity, but its evolutionary consequences depend on how plastic responses align with the broader adaptive landscape.

Whole‐genome duplication promotes phenotypic and genetic adaptation to elevation

open access: yesNew Phytologist, EarlyView.
Fitness of diploids (2x) and tetraploids (4x) of Biscutella laevigata from low (circles) and high (triangles) elevation transplanted across elevation at 585, 1236 and 1967 m above sea level. Summary Whole‐genome duplication (WGD) is often considered as either an adaptive dead‐end or a facilitator of rapid adaptation under changing environments.

Screening for Fall Armyworm (Spodoptera frugiperda J. E. Smith) Resistance in Early‐Maturing Tropical Maize Adapted to Sub‐Saharan Africa

open access: yesPlant Breeding, EarlyView.
ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) has emerged as a serious pest since 2016 in Africa, affecting the food security and livelihoods of millions of smallholder farmers, especially those growing maize. Native genetic resistance to FAW is essential for reducing yield loss.

Nonequivalent lethal equivalents: Models and inbreeding metrics for unbiased estimation of inbreeding load

open access: yesEvolutionary Applications, 2019
Inbreeding depression, the deterioration in mean trait value in progeny of related parents, is a fundamental quantity in genetics, evolutionary biology, animal and plant breeding, and conservation biology.

Additive Variance and Open‐Pollinated Progenies Under Mixed Mating

open access: yesPlant Breeding, EarlyView.
ABSTRACT Open‐pollinated progeny tests are still widely interpreted as if all the individuals within a maternal family were true half‐sibs. However, in species with mixed mating systems, this assumption is often biologically unrealistic and may bias the estimation of the additive variance, narrow‐sense heritability and expected selection gains.

A Century of Understanding and Harnessing Heterosis

open access: yesPlant Breeding, EarlyView.
ABSTRACT Heterosis has shaped modern plant breeding since Darwin's 19th century observations that outcrossing restores vigour lost through selfing. While 100 years old, its mechanistic basis and deployability remain actively debated. Classical models of dominance, overdominance and epistasis provided the foundation for hybrid breeding and converted ...

Comparison among Inbreeding Systems in Maize

open access: yesCrop Breeding and Applied Biotechnology, 2001
The use of less severe inbreeding systems than self-fertilization has been suggested as a means of developing more vigorous maize lines (Zea mays L.). To compare different inbreeding systems, nine traits were evaluated in inbred lines developed by full ...

Effects of crossing distance on components of fitness in two rare rock plants

open access: yesPlant Biology, EarlyView.
Crossing experiments between populations of the rare rock species Saxifraga rosacea ssp. rosacea (8×) and S. rosacea ssp. sponhemica (6×) resulted in heterosis for some traits and outbreeding depression for others. Crossing the two subspecies resulted in sterile hybrids indicating that mixing populations of rare species is not always beneficial ...
