A conserved graft formation process in Picea abies and Arabidopsis thaliana identifies the PAT gene family as central regulators of wound healing

Auxin signaling in the cambium promotes tissue attachment and vascular development during Arabidopsis thaliana graft formation

This study shows auxin signaling in procambial tissues is essential for tissue attachment and vascular development during Arabidopsis thaliana graft formation.

Damage activates EVG1 to suppress vascular differentiation during regeneration in Arabidopsis thaliana

The paper identifies EVG1 as a gene that suppresses vascular differentiation during plant regeneration in response to damage, showing its role in stress responses and interactions with RLP44.

PME-mediated pectin modifications promote haustoria initiation and xylem bridge development in the parasitic plant Phtheirospermum japonicum

The regeneration factors ERF114 and ERF115 act as transducers of mechanical cues to developmental pathways

This study shows that ERF114 and ERF115 mediate mechanical cues to switch between developmental and regenerative processes in plants.

High temperature perception in leaves promotes vascular regeneration in distant tissues

This study shows elevated temperatures enhance vascular regeneration in plant grafts, mediated by leaf-derived auxin, and this effect is not limited to graft healing.

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.

Analysis of phloem trajectory links tissue maturation to cell specialization.

The paper reconstructs the protophloem developmental trajectory in Arabidopsis root cells to show how maturation gradients and transcription factors regulate cell specialization.

Bipartite influence of abscisic acid on xylem differentiation trajectories is dependent on distinct VND transcription factors in Arabidopsis

This study shows that ABA influences xylem differentiation through distinct VND transcription factors in Arabidopsis, revealing genetic independence in cell fate and differentiation rate.

Shoot-to-root translocation of the jasmonate precursor 12-oxo-phytodienoic acid (OPDA) coordinates plant growth responses following tissue damage

This study identifies OPDA as a mobile jasmonate precursor that translocates from damaged shoots to roots, coordinating growth responses in Arabidopsis.

Transcriptome dynamics at the Arabidopsis graft junction reveal an inter-tissue recognition mechanism that activates vascular regeneration

The paper studies gene expression changes in grafted Arabidopsis hypocotyls to identify a recognition mechanism that activates vascular regeneration.

Nitrate modulates stem cell dynamics by regulating WUSCHEL expression through cytokinins

The paper shows nitrate regulates stem cell dynamics by modulating WUSCHEL expression via cytokinins, enabling plants to adapt to nutrient availability.
