The PIN2 ortholog in barley modifies root gravitropism and architecture without impacting the shoot

This study shows that knocking out PIN2 in barley alters root gravitropism and architecture without affecting shoot growth.

Metagenomic ecosystem monitoring of soft scale and mealybug infestations in Australian vineyards

The paper develops a metagenomic pipeline to identify and quantify insect pests in vineyards, finding Parthenolecanium corni as the dominant scale species.

Control of N2 fixation and NH3 excretion in Azorhizobium caulinodans ORS571

This paper engineers Azorhizobium caulinodans to control N2 fixation and NH3 excretion using rhizopine-inducible systems to target nitrogen delivery to transgenic crops.

Disrupting hierarchical control of nitrogen fixation enables carbon-dependent regulation of ammonia excretion in soil diazotrophs

This study shows that a single amino acid change in NifA disrupts nitrogen fixation regulation in Azotobacter vinelandii, enabling carbon-dependent ammonia excretion.

Deep sequencing reveals Campylobacter in commercial meat chickens less than 8 days old.

The paper uses molecular methods to detect Campylobacter in young chickens, finding that most carry the bacteria before traditional culture methods can detect it.

Genomic analysis on broiler-associated Clostridium perfringens strains and caecal microbiome profiling reveals key factors linked to poultry Necrotic Enteritis

This study identifies hypervirulent Clostridium perfringens strains and microbiome changes associated with necrotic enteritis in broiler chickens.
