Comparing hormone dynamics in cereal crops via transient expression of hormone sensors

This study compares GA and auxin responses across cereal crops using hormone sensors and transcriptomics, identifying conserved and species-specific GA-response mechanisms.

Gibberellin Perception Sensors 1 and 2 reveal cellular GA dynamics articulated by COP1 and GA20ox1 that are necessary but not sufficient to pattern hypocotyl cell elongation

The paper uses a GA biosensor to show COP1 and GA20ox1 regulate GA gradients in hypocotyls, which are necessary but not sufficient for cell elongation during light and dark conditions.

Stomata, a vulnerability in the plant defence against phytophagous mites that ABA can overcome

This study shows that ABA-induced stomatal closure in Arabidopsis thaliana reduces mite infestation and leaf damage by blocking mite feeding access.

Cellular gibberellin dynamics govern indeterminate nodule development, morphologyand function

This study identifies cellular gibberellin dynamics as a positive regulator of nodule growth and development in legumes, distinct from lateral root formation.

Auxin coreceptor IAA17/AXR3 controls cell elongation in Arabidopsis thaliana root by modulation of auxin and gibberellin perception

This study shows that AXR3-1 modulates auxin and gibberellin perception to control cell elongation in Arabidopsis root, leading to altered growth and homeostasis.

Next-generation ABACUS biosensors reveal cellular ABA dynamics driving root growth at low aerial humidity

The paper develops ABACUS2s, high-resolution ABA biosensors, to map ABA dynamics in Arabidopsis roots under low humidity, showing ABA's role in maintaining root growth.

ABA signaling prevents phosphodegradation of the Arabidopsis SR45 splicing factor to negatively autoregulate inhibition of early seedling development

This study shows ABA signaling dephosphorylates SR45, reducing its ubiquitination and degradation, thereby negatively autoregulating early seedling development.

Phosphorylation dynamics in a flg22-induced, heterotrimeric G-protein dependent signaling network in Arabidopsis thaliana reveals a candidate PP2A phosphatase involved in AtRGS1 trafficking

A quantitative gibberellin signalling biosensor reveals a role for gibberellins in internode specification at the shoot apical meristem

The paper develops a GA signalling biosensor to study GA's role in internode specification at the shoot apical meristem, finding GA activity is high between organ primordia and regulates cell division plane orientation.

Intrinsically disordered protein biosensor tracks the physical-chemical effects of osmotic stress on cells

The paper develops a FRET biosensor using intrinsically disordered proteins to monitor osmotic stress effects across multiple organisms.

Evolutionarily ancient role of cholecystokinin-type neuropeptide signalling as an inhibitory regulator of feeding-related processes revealed in an echinoderm

The paper identifies CCK/SK-type neuropeptides in starfish, showing they inhibit feeding-related processes through muscle contraction and retraction.

Family permutation profiling identifies a dynamic protein domain as functionally tolerant to increased conformational entropy

This study uses family permutation profiling and deep mutational scanning to show that high energetic frustration in protein domains correlates with increased tolerance to conformational entropy.

A decoy heterotrimeric Gα protein has substantially reduced nucleotide binding but retains nucleotide-independent interactions with its cognate RGS protein and Gβγ dimer

This paper shows that Arabidopsis XLG2 has reduced nucleotide binding but maintains interactions with RGS and Gβγ, suggesting it functions as a dominant negative G protein.

Receptor-Like Kinase Phosphorylation of Arabidopsis Heterotrimeric G-Protein Gα - Subunit AtGPA1

This study identifies phosphorylation sites on AtGPA1 by 12 RLKs and characterizes their functional relevance in Arabidopsis G protein signaling.
