Cold-induced Arabidopsis FRIGIDA nuclear condensates for FLC repression
In Arabidopsis thaliana, downregulation of the floral repressor FLC in response to cold occurs through a mechanism in which the FLC activator FRIGIDA is sequestered into biomolecular condensates away from the FLC promoter.

The strength and pattern of natural selection on gene expression in rice
Phenotypic selection analysis is used to estimate the type and strength of selection that acts on more than 15,000 transcripts in rice (Oryza sativa), which provides insight into the adaptive evolutionary role of selection on gene expression.

A small peptide modulates stomatal control via abscisic acid in long-distance signalling
In an Arabidopsis model, the CLE25 peptide acts as a root-to-shoot signalling molecule that modulates abscisic acid expression to close stomata and enhance resistance to dehydration.

Root microbiota drive direct integration of phosphate stress and immunity
In Arabidopsis thaliana, a genetic network that controls the phosphate stress response also influences the structure of the root microbiome community, even under non-stress phosphate conditions.

Reducing phosphorus accumulation in rice grains with an impaired transporter in the node
The phosphorous transporter SPDT is identified in rice; depletion of the transporter gene alters the phosphorus distribution in rice grains and leaves, suggesting that the strategy could be used for agricultural purposes.

Carbonic anhydrases, EPF2 and a novel protease mediate CO2 control of stomatal development
The continuing rise in atmospheric carbon dioxide concentrations suppresses the development of stomatal pores, and thus gas exchange, in plant leaves on a global scale; now, a framework of mechanisms by which carbon dioxide represses development has been identified.
