Sterol 3-beta-Glucosyltransferase TRANSPARENT TESTA15 Controls Seed Development and Flavanol Accumulation through its Role in Vacuole Biogenesis and Maintenance in Arabidopsis

This study shows that TT15 controls seed development and flavanol accumulation by modulating vacuole biogenesis and maintenance in Arabidopsis.

Post-translational regulation of photosynthetic activity via the TOR kinase in plants.

The paper identifies a TOR-RSH3 signaling axis that post-translationally regulates photosynthetic activity in plants by controlling ppGpp signaling.

Arabidopsis hydathodes are sites of intense auxin metabolism and nutrient scavenging

The paper analyzes the transcriptomic and metabolomic profiles of Arabidopsis hydathodes, revealing their role in auxin metabolism and nutrient scavenging.

A ppGpp-mediated brake on photosynthesis is required for acclimation to nitrogen limitation in Arabidopsis.

This study shows that ppGpp is essential for Arabidopsis to acclimate to nitrogen limitation by remodeling photosynthesis and coordinating chloroplast-nuclear gene expression.

Guanosine tetraphosphate (ppGpp) accumulation inhibits chloroplast gene expression and promotes super grana formation in the moss Physcomitrium (Physcomitrella) patens

This study shows that ppGpp accumulation in moss inhibits chloroplast gene expression and causes super grana formation without affecting growth.

Hypomethylated poplars show higher tolerance to water deficit and highlight a dual role for DNA methylation in shoot meristem: regulation of stress response and genome integrity

This study shows hypomethylated poplars are more drought-tolerant and reveals DNA methylation's role in stress response and genome integrity in shoot meristems.

ppGpp influences protein protection, growth and photosynthesis in Phaeodactylum tricornutum

This study shows that ppGpp reduces photosynthesis and promotes a quiescent state in diatoms, while inducing a protein protection response.

Quantification of guanosine tetraphosphate and other nucleotides in plants and algae using stable isotope-labelled internal standards.

This study develops a method for accurate and rapid quantification of G4P in plants and algae using stable isotope-labelled internal standards.

Sugar availability suppresses the auxin-induced strigolactone pathway to promote bud outgrowth

This study shows that sugar availability suppresses the auxin-induced strigolactone pathway, promoting bud outgrowth, and develops a computational model to quantify this interaction.

Novel cytonuclear combinations modify Arabidopsis seed physiology and vigor

This study examines how cytonuclear combinations in Arabidopsis affect seed traits like dormancy, germination, and longevity, revealing both negative and positive effects on seed vigor.
