Modification of xylan in secondary walls alters cell wall biosynthesis and wood formation programs

This study modifies xylan in secondary walls of hybrid aspen to reduce recalcitrance, resulting in altered growth patterns and improved enzymatic saccharification.

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.

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.

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.

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.

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.
