The paper presents comprehensive DNA metabarcoding data from Sweden and Madagascar, characterizing terrestrial arthropod faunas and providing insights into community composition and dynamics.

The Arabidopsis splicing factor PORCUPINE/SmE1 orchestrates temperature-dependent root development via auxin homeostasis maintenance

This study shows that the splicing factor PORCUPINE regulates temperature-dependent root development in Arabidopsis by maintaining auxin homeostasis in the root apical meristem.

KIPK and KIPK-LIKE1 suppress overbending during negative hypocotyl gravitropic growth

This study identifies KIPK and KIPKL1 as regulators that suppress overbending during hypocotyl gravitropic growth by modulating ARK kinesins and cortical microtubules.

GOLVEN peptides regulate lateral root spacing as part of a negative feedback loop on the establishment of auxin maxima

This study shows GLV6/10 peptides inhibit auxin maxima formation in xylem-pole pericycle cells, regulating lateral root spacing through a negative feedback loop involving PIN3 and PIN7.

GAUT10 is required for Arabidopsis root cell differentiation and elongation

This study shows GAUT10 is essential for root cell differentiation and elongation in Arabidopsis by affecting cell wall composition and auxin signaling.

The Arabidopsis ATP-Binding Cassette E protein ABCE2 is a conserved component of the translation machinery

This study identifies ABCE2 as a conserved ribosome recycling factor in Arabidopsis, showing its role in growth and vascular development through auxin metabolism.

IPT9, a cis-zeatin cytokinin biosynthesis gene, promotes root growth

The paper investigates the role of IPT9 in cytokinin biosynthesis and its impact on root growth, finding that IPT9 affects auxin homeostasis and contributes to a short-root phenotype despite reduced cis-zeatin levels.

Timing Is Everything In Autumn - Coordination Of Senescence Onset By A Transcriptional Program In Response To Environmental And Phytohormone Signals

The paper identifies a salicylic acid signaling pathway that fine-tunes senescence timing in aspen trees in response to environmental stress.

Cytokinin signalling regulates two-stage inflorescence arrest in Arabidopsis

This study shows cytokinin signaling regulates two-stage inflorescence arrest in Arabidopsis by delaying meristem and floral arrest through receptor expression patterns and sink organ dilution.

Inactivation of the entire Arabidopsis group II GH3s confers tolerance to salinity and drought

This study shows that knocking out group II GH3 genes in Arabidopsis improves root architecture and stress tolerance by increasing IAA levels and involving ABA in stress responses.

PcGCE is a potent elicitor of defense responses in aspen

This paper shows that PcGCE, a microbial enzyme, acts as a pathogen-associated molecular pattern in aspen, triggering immune responses and growth retardation when expressed in transgenic plants.

Nitrates increase abscisic acid levels to regulate haustoria formation in the parasitic plant Phtheirospermum japonicum

This study shows nitrates inhibit haustoria formation in parasitic plants by increasing abscisic acid levels, with effects observed in both facultative and obligate parasites.

KAI2 regulates seedling development by mediating light-induced remodelling of auxin transport

This study shows KAI2 regulates light-induced auxin transport remodeling in seedlings by controlling PIN protein abundance, not gene expression, and its loss leads to altered growth patterns.

Redefining the roles of UDP-glycosyltransferases in auxin metabolism and homeostasis during plant development

The paper shows UGT84B1 and UGT74D1 regulate IAA levels through glycosylation of both IAA and oxIAA, and identifies a new UGT subfamily involved in oxIAA glycosylation during skotomorphogenesis.

DNA damage inhibits root growth by enhancing cytokinin biosynthesis in Arabidopsis thaliana.

This study shows DNA damage in Arabidopsis roots increases cytokinin synthesis, which suppresses auxin transport and reduces root growth.

Shoot and root thermomorphogenesis are linked by a developmental trade-off

The paper shows that shoot and root growth responses to high temperature are coordinated during early seedling development through shared signaling modules and auxin regulation.

Auxin export from proximal fruits drives arrest in competent inflorescence meristems

This study shows floral arrest in Arabidopsis is a local process driven by auxin export from fruits, challenging the idea of global proliferative arrest.

Conifers exhibit a characteristic inactivation of auxin to maintain tissue homeostasis

The paper investigates IAA inactivation pathways in conifers, finding that oxidative and conjugative pathways differ in their contribution to auxin homeostasis compared to Arabidopsis.

Cell-surface receptors enable perception of extracellular cytokinins

The paper shows that cytokinin perception occurs via plasma membrane receptors in root cells, challenging previous assumptions about receptor localization and highlighting the role of spatial distribution in signaling.

A bacterial assay for rapid screening of IAA catabolic enzymes

This paper introduces a bacterial assay to rapidly screen IAA catabolic enzymes by measuring enzymatic products directly from bacterial cultures without protein purification.

A role for the auxin precursor anthranilic acid in root gravitropism via regulation of PIN-FORMED protein polarity and relocalization in Arabidopsis

This study shows that anthranilic acid regulates PIN-FORMED protein polarity and relocalization in Arabidopsis roots, affecting gravitropism independently of its role in IAA biosynthesis.

Flowering behaviour in Arabis alpina ensures the maintenance of a perennating dormant bud bank

This study shows that floral development during vernalization in Arabis alpina shapes the dormant bud zone by promoting synchronized growth and auxin levels after warming, while apical dominance and temperature regulate dormancy.

KAI2 regulates root and root hair development by modulating auxin distribution

This study identifies the role of KAI2 in regulating root and root hair development by modulating auxin distribution in Arabidopsis through KL signaling.
