Estimating self-fertilization rates from the diploid genotype spectrum

This paper introduces a method to estimate self-fertilization rates using diploid genotype spectra from population genomic data.

Unmasking the large and highly repetitive genome of Phlox reveals a complex evolutionary history of speciation with gene flow

The paper presents chromosome-level genome assemblies and population genetic data for three Phlox species, revealing extensive genetic variation and widespread gene flow during speciation.

High-throughput iNaturalist image analysis reveals flower color divergence in Monarda fistulosa

The paper analyzes community science images of Monarda fistulosa to show geographic divergence in flower color, finding western flowers are deeper violet than eastern ones.

Variation in response to water availability across Phlox species

This study examines how three Texas Phlox species and their hybrids respond to water availability, finding that plasticity in morphology varies independently of niche breadth.

The genetic architecture of quantitative variation in the self-incompatibility response within Phlox drummondii (Polemoniaceae)

This study investigates the genetic architecture of self-compatibility variants in Phlox drummondii, finding polygenic QTLs and a novel S-locus associated with self-incompatibility variation.

A lectin receptor-like kinase controls self-pollen recognition in Phlox (Polemoniaceae)

This study identifies a gene, PdPIRK, responsible for self-pollen recognition in Phlox, showing its necessity for self-incompatibility and its role in the S-locus.

A massive community-science dataset reveals convergent evolution of delayed flowering phenology in North American red-flowering plants

The paper uses AI to analyze community science data and shows red/orange flowers in North America flower later, aligning with hummingbird migration patterns, suggesting flowering time is part of a pollination syndrome.

Mismatch between pollen and pistil size causes asymmetric mechanical reproductive isolation across Phlox species

The paper investigates how differences in style length between Phlox species create an asymmetric mechanical barrier to reproduction, reducing heterospecific seed set and revealing a link between pollen size and pollen tube growth.

Quantifying the relationship between pollinator behavior and plant reproductive isolation

The paper develops a model to quantify how pollinator behavior affects plant reproductive isolation by analyzing the impact of constancy and preference on heterospecific mating proportions.
