Haplotype-phased assemblies of the two poplar rust fungi species: Melampsora larici-populina and Melampsora allii-populina

The paper presents haplotype-phased, near chromosome-scale genome assemblies for two poplar rust fungi species, improving contiguity and enabling analysis of genome architecture and virulence genes.

Behind the shadow play: Shedding light on the population genetics of partially clonal organisms through clone age distributions

This study simulates partially clonal populations to explore how clonality rates affect clone age distributions and genetic diversity over time.

Ancestral and recent bursts of transposition shaped the massive genomes of plant pathogenic rust fungi

The paper analyzes transposable element dynamics in rust fungi, finding that LTR-Gypsy elements drive genome expansion, with significant proliferation events occurring within the last 50 million years.

The genetic diversity of the soybean rust pathogen Phakopsora pachyrhizi has been driven by two major evolutionary lineages

This study analyzes the genetic diversity of Phakopsora pachyrhizi, identifying two major evolutionary lineages and suggesting a tetrapolar mating system.

Long-lasting coexistence of multiple asexual lineages alongside their sexual counterparts in a fungal plant pathogen

The paper studies the coexistence of asexual and sexual lineages in the poplar rust fungus over 30 years, finding persistent asexual lineages with genetic clonality and ecological structuring.

A chromosome-scale genome assembly of the flax rust fungus reveals the two unusually large effector proteins, AvrM3 and AvrN

This study presents a chromosome-scale genome assembly of the flax rust fungus, revealing two large effector proteins, AvrM3 and AvrN, and providing insights into its mating system.

Transcriptome analysis of apple leaves infected by the rust fungus Gymnosporangium yamadae at two sporulation stages (spermogonia and aecia) reveals specific host responses, rust pathogenesis-related genes and a shift in the phyllosphere fungal community composition

This study uses dual RNA-seq to analyze gene expression in apple leaves and Gymnosporangium yamadae during rust infection, revealing host responses, pathogen genes, and changes in phyllosphere fungal communities.

RUST FUNGAL EFFECTORS MIMIC HOST TRANSIT PEPTIDES TO TRANSLOCATE INTO CHLOROPLASTS

The paper identifies CTP1, a fungal effector that mimics plant chloroplast transit peptides to translocate into chloroplasts, revealing a strategy for fungal manipulation of host cell compartments.
