Genome-wide neighbor effects predict genotype pairs that reduce herbivory in mixed planting

The paper identifies genotype pairs in Arabidopsis thaliana that reduce herbivory through associational resistance when planted in mixtures.

Hyper-Cryptic Radiation of a Tropical Montane Plant Lineage

The paper analyzes genetic data from a tropical montane plant lineage to show it contains multiple unrecognized genetic groups that are not morphologically distinct, revealing a hyper-cryptic radiation.

PlantServation: time-series phenotyping using machine learning revealed seasonal pigment fluctuation in diploid and polyploid Arabidopsis

PlantServation uses machine learning to analyze field images and estimate anthocyanin content in Arabidopsis, revealing seasonal fluctuations influenced by environmental factors.

Genome-wide association study highlights escape from aphids by delayed growth in Arabidopsis thaliana

This study identifies a growth-related gene in Arabidopsis thaliana associated with reduced aphid abundance through delayed growth and flowering.

Detecting frequency-dependent selection through the effects of genotype similarity on fitness components

The paper introduces a method to detect frequency-dependent selection by analyzing genotype similarity's effect on fitness components using regression analysis in Arabidopsis and damselfly data.

The UV RESISTANCE LOCUS 8-Mediated UV-B Response Is Required Alongside CRYPTOCHROME1 For Plant Survival Under Sunlight In The Field

This study shows that UVR8 and CRY1 work together in Arabidopsis to help plants survive UV-B radiation in natural conditions, with UVR8 playing a key role in long-term survival.

Using a two-stage convolutional neural network to rapidly identify tiny herbivorous beetles in the field

The paper develops a two-stage CNN method to improve identification of tiny beetles in the field, achieving higher precision than single-stage models.

Fine-scale ecological and transcriptomic data reveal niche differentiation of an allopolyploid from diploid parents in Cardamine

This study examines the ecological and transcriptomic differences between an allopolyploid plant and its diploid parents, finding niche differentiation linked to water availability.

A recently formed triploid Cardamine insueta inherits leaf vivipary and submergence tolerance traits of parents

This study characterizes the transcriptomic response of a recently formed triploid plant species to submergence, revealing inherited traits from its parental species.

Genomic signals of admixture and reinforcement between two closely related species of European sepsid flies

The paper examines gene flow and reinforcement between two European dung fly species using genomic data from sympatric and allopatric populations.

Transcriptional variation in glucosinolate biosynthetic genes and inducible responses to aphid herbivory on field-grown Arabidopsis thaliana

The paper examines transcriptional variation in glucosinolate biosynthetic genes and inducible responses to aphid herbivory in field-grown Arabidopsis thaliana using RNA-Seq and insect survey data.

Plant trichomes and a single gene GLABRA1 contribute to insect community composition on field-grown Arabidopsis thaliana

The paper investigates how genetic variation in the GLABRA1 gene affects insect communities on Arabidopsis thaliana by comparing glabrous mutants and natural accessions in two field sites.

Adaptive Reduction of Male Gamete Number in a Selfing Species

The paper uses GWAS to show polygenic selection on pollen number in Arabidopsis thaliana, identifies a gene affecting pollen number, and validates its causal role using CRISPR-Cas9 mutants.

Patterns of polymorphism, selection and linkage disequilibrium in the subgenomes of the allopolyploid Arabidopsis kamchatica

The paper analyzes polymorphism, selection, and linkage disequilibrium in the subgenomes of Arabidopsis kamchatica, finding reduced purifying selection and increased adaptive substitutions compared to parental species.
