Transcriptomic analyses in the gametophyte ofDryopteris affinis: apomixis and more

The paper identifies and analyzes proteins involved in apomixis and stress responses in the gametophyte of Dryopteris affinis using transcriptomic data.

Uncovering genes involved in pollinator-driven mating system shifts and selfing syndrome evolution in Brassica rapa

This study identifies genes associated with mating system shifts and selfing syndrome evolution in Brassica rapa under hoverfly pollination, revealing polygenic changes in floral morphology.

Functional genetics of rice PISTILLATA genes unravels new roles and targets in flowering time, female fertility and parthenocarpy

The paper investigates the functional roles of rice PISTILLATA paralogs OsMADS2 and OsMADS4 in flowering time, female fertility, and parthenocarpy through genetic perturbations and gene target analysis.

HISTONE DEACETYLASE 19 REGULATES SHOOT MERISTEMLESS EXPRESSION IN THE CARPEL MARGIN MERISTEM CONTRIBUTING TO OVULE NUMBER DETERMINATION AND TRANSMITTING TRACT DIFFERENTIATION

This study identifies HDA19's role in downregulating STM in the CMM to enable ovule formation and transmitting tract differentiation in Arabidopsis.

A paternal signal induces endosperm proliferation upon fertilization in Arabidopsis

This study identifies CYCD7;1 as a paternal signal that triggers central cell division in Arabidopsis by degrading RBR1 after fertilization.

Single-gene resolution of diversity-driven community overyielding

The paper identifies a gene, AtSUC8, whose allelic differences contribute to increased productivity in mixed Arabidopsis thaliana genotypes by affecting root growth sensitivity to substrate pH.

Increasing plant group productivity through latent genetic variation for cooperation

The paper identifies a genetic locus that promotes cooperation in plant stands, increasing productivity in high-density monocultures by reducing root competition and enhancing disease resistance.

Apomixis and genetic background affect distinct traits in Hieracium pilosella L. grown under competition

This study examines how apomixis and genetic background influence fitness traits in Hieracium pilosella under competition, showing independent effects of both factors on survival and reproduction.

The single Marchantia polymorpha FERONIA homolog reveals an ancestral role in regulating cellular expansion and integrity

The study identifies MpFER, the single CrRLK1L gene in Marchantia polymorpha, and shows it regulates cell expansion and integrity, revealing an ancestral function in land plants.

Organ geometry channels cell fate in the Arabidopsis ovule primordium

The paper investigates how organ geometry influences spore mother cell differentiation in Arabidopsis ovule primordium through 3D imaging and growth models.

Endosperm and seed transcriptomes reveal possible roles for small RNA pathways in wild tomato hybrid seed failure

The paper analyzes transcriptomes and small RNA expression in hybrid tomato seeds to identify roles for small RNA pathways in hybrid seed failure.

Dynamics of apomictic and sexual reproduction during primary succession on a glacier forefield in the Swiss Alps

This study examines apomictic and sexual reproduction in Hieracium pilosella during primary succession, finding that apomixis is more common in odd- and aneuploid cytotypes, which are more frequent early in succession.

The mechanical basis for snapping of the Venus flytrap, Darwin’s ‘most wonderful plant in the world’

The paper develops an electromechanical model and uses microrobotics to show that one touch can generate two action potentials in Venus flytrap sensory hairs, suggesting it can catch prey with fewer stimuli than previously thought.

Structural basis for recognition of RALF peptides by LRX proteins during pollen tube growth

The paper reports the crystal structure of the LRX-RALF complex and shows RALF peptides function as folded, disulfide-stabilized proteins that bind LRXs with nanomolar affinity.

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.

Feeling the force: how pollen tubes deal with obstacles

This study measures how pollen tubes detect and respond to mechanical obstacles by quantifying force sensitivity in Lilium longiflorum and Arabidopsis thaliana.

LRX Proteins play a crucial role in pollen grain and pollen tube cell wall development

This study investigates the role of LRX proteins in pollen grain and pollen tube development in Arabidopsis, showing defects in germination and growth when LRX genes are mutated.

Consistent Reanalysis of Genome-wide Imprinting Studies in Plants Using Generalized Linear Models Increases Concordance across Datasets

The paper reanalyzes genome-wide imprinting studies in plants using generalized linear models, showing increased concordance in Arabidopsis but not maize, highlighting the impact of analysis methods and other factors.
