Colonization by orchid mycorrhizal fungi primes induced systemic resistance against a necrotrophic pathogen

This study shows that colonization by a compatible orchid mycorrhizal fungus primes induced systemic resistance in Bletilla striata against a necrotrophic pathogen by modulating jasmonate and ethylene pathways, similar to arbuscular mycorrhizal plants.

Synthetic Peptide Nucleic Acids in Action: In Vivo Interference of the groEL Gene from Pea Aphid Endosymbiont Buchnera aphidicola

This study uses synthetic antisense PNAs conjugated to CPPs to knock down the groEL gene in Buchnera aphidicola, causing reduced expression and morphological changes.

Orchid seed germination through auto-activation of mycorrhizal symbiosis signaling regulated by gibberellin

This study investigates how gibberellin (GA) affects Bletilla striata seed germination and mycorrhizal symbiosis, revealing that GA inactivation enables auto-activation of the symbiosis pathway.

Monoterpene glucosides accumulated in Eustoma grandiflorum roots promote hyphal branching in arbuscular mycorrhizal fungi

Evolution of horn length and lifting strength in the Japanese rhinoceros beetle Trypoxylus dichotomus

The paper studies the evolution of horn length and lifting strength in Trypoxylus dichotomus, showing independent increases in horn length in Northern and Southern lineages with mechanical trade-offs and compensatory changes.

Seasonal polyphenism underlies the origin of a sterile caste in aphids

This study shows that seasonal polyphenism in aphids was repurposed to evolve a sterile soldier caste, with shared developmental mechanisms and fitness benefits.

Complex host/symbiont integration of a multi-partner symbiotic system in the eusocial aphid Ceratovacuna japonica

The paper identifies a co-obligate symbiosis in the aphid Ceratovacuna japonica, revealing metabolic complementarity between two endosymbionts and caste-specific differences in symbiont populations.

Gene expression profiles of chemosensory genes of termite soldier and worker antennae

The paper compares gene expression in worker and soldier antennae of termites to identify chemosensory genes involved in caste-specific social behaviors.

Single-nucleotide substitution determines pollen production in Japanese cedar

This study identifies a single-nucleotide substitution in the TKPR1 gene that determines pollen production in Japanese cedar and suggests its potential application in creating pollen-free plants.

Lipid-correlated alterations in the transcriptome are enriched in several specific pathways in the postmortem prefrontal cortex of Japanese patients with schizophrenia

The paper integrates transcriptome and lipidome data from postmortem prefrontal cortex samples of schizophrenia patients to identify lipid-correlated gene expression changes in specific pathways.

Ploidy dynamics in aphid host cells harboring bacterial symbionts

This study quantifies ploidy levels in aphid bacteriocytes across their lifecycle, revealing dynamic changes associated with different phenotypes and developmental stages.

Conservation and diversity in transcriptional responses among host plants forming distinct arbuscular mycorrhizal morphotypes

The paper investigates transcriptional responses to arbuscular mycorrhizal (AM) symbiosis and gibberellin (GA) treatment in three host plants with distinct AM morphotypes, finding conserved and divergent gene expression patterns.

Evolutionary transition of doublesex regulation in termites and cockroaches: from sex-specific splicing to male-specific transcription

This study investigates the evolutionary transition of dsx regulation in termites and cockroaches, finding a shift from sex-specific splicing to male-specific transcription in termites.

Transcriptomic analysis of resistant and susceptible responses in a new model root-knot nematode infection system using Solanum torvum and Meloidogyne arenaria

This study compares gene expression responses in Solanum torvum infected with two Meloidogyne arenaria pathotypes, identifying distinct molecular mechanisms of resistance and susceptibility.

Chloroplast acquisition without the gene transfer in kleptoplastic sea slugs, Plakobranchus ocellatus

This study sequenced the genome of a kleptoplastic sea slug and found no evidence of algal gene transfer to the nucleus, showing photosynthesis can occur without nuclear gene transfer.

Switching secretory pathway direction for organelle acquisition in plants

The paper identifies a mechanism in liverworts for acquiring oil bodies through switching secretory pathway direction during cellular phase transitions.

Genomic profiling of PML bodies reveals transcriptional regulation by PML bodies through the DNMT3A exclusion

The paper identifies genomic regions associated with PML bodies and shows their role in maintaining hypo-methylated states at Y-linked gene promoters through DNMT3A exclusion.

The RopGEF KARAPPO is Essential for the Initiation of Vegetative Reproduction in Marchantia

This study identifies KARAPPO, a RopGEF, as essential for initiating vegetative reproduction in Marchantia by promoting gemma initial formation through Rop signaling.

Repeated inversions at the pannier intron drive diversification of intraspecific colour patterns of ladybird beetles

The paper identifies pannier as a key regulatory gene for color pattern variation in ladybird beetles and shows that inversions and cis-regulatory changes at this gene drive intraspecific diversity.

The genomic landscape at a late stage of stickleback speciation: high genomic divergence interspersed by small localized regions of introgression

This paper examines genomic divergence in a late-stage stickleback species pair, showing high genome-wide differentiation persists despite ongoing introgression in small recombination hotspots.
