Proliferation in malaria parasites: how resource limitation can prevent evolution of greater virulence

The paper models how resource limitation, rather than virulence-transmission tradeoffs, restricts evolution of higher proliferation rates in malaria parasites.

The impact of innate immunity on malaria parasite infection dynamics

This study performs a meta-analysis of rodent malaria parasite infection dynamics to assess the impact of innate immunity, finding small effect sizes and variability explained by stochasticity and experimental factors.

SEN1 is responsible for molybdate transport into nodule symbiosomes for nitrogen fixation in Lotus japonicus

The paper identifies SEN1 as a molybdate transporter responsible for exporting molybdate from host plant cytosol to symbiosomes for nitrogen fixation in Lotus japonicus.

Root-specific activation of plasma membrane H+-ATPase 1 enhances plant growth and shoot accumulation of nutrient elements under nutrient-poor conditions in Arabidopsis thaliana

This study shows that root-specific activation of PM H+-ATPase in Arabidopsis improves growth and nutrient uptake under poor conditions without affecting stomatal function.

Regulation of ammonium acquisition and use in Oryza longistaminata ramets under nitrogen source heterogeneity

Oryza longistaminata regulates ammonium acquisition and use in response to spatial nitrogen heterogeneity through inter-ramet communication.

Regulation of suberin biosynthesis and Casparian strip development in the root endodermis by two plant auxins

This study shows that PAA and IAA regulate suberin biosynthesis and Casparian strip development differently in root endodermis, with auxin antagonistically affecting CS formation.

CASP microdomain formation requires cross cell wall stabilization of domains and non-cell autonomous action of LOTR1

The paper shows that LOTR1, an extracellular protease, is required for non-cell-autonomous positioning of Casparian Strip domains in plants, coordinating their formation across neighboring cells.

PIN FORMED 2 facilitates the transport of Arsenite in Arabidopsis thaliana

This study shows PIN2 facilitates arsenite transport in Arabidopsis, leading to arsenite accumulation and root growth inhibition.

OsNLP4 is required for nitrate assimilation gene expressions and nitrate-dependent growth in rice

The study identifies OsNLP4 as essential for nitrate assimilation gene expression and nitrate-dependent growth in rice.

Two Receptor-Like Kinases Required For Arabidopsis Endodermal Root Organisation Shape The Rhizosphere Microbiome

This study identifies ERK1 and RBK1 as key regulators of Casparian Strip formation in Arabidopsis, which in turn influences rhizosphere microbiome composition.

Coevolution of virulence and immunosuppression in multiple infections

This study shows immunosuppression in parasites can both enhance and hinder virulence evolution through multiple infections, depending on host mortality and trade-off shapes.
