The study generated a single‑cell transcriptomic atlas of tomato adventitious root development, revealing that vascular tissues retain high developmental potential and that the DOF11‑LEA3 regulatory axis drives this process. Cross‑species integration shows tomato AR‑initiating cells share transcriptional programs with woody dicots but not Arabidopsis, suggesting AR competence is an ancestral vascular identity module. These results highlight tomato as a more representative model for AR biology and provide targets for improving vegetative propagation.

The authors used a bottom‑up thermodynamic modelling framework to investigate how plants decode calcium signals, starting from Ca2+ binding to EF‑hand proteins and extending to higher‑order decoding modules. They identified six universal Ca2+-decoding modules that can explain variations in calcium sensitivity among kinases and provide a theoretical basis for interpreting calcium signal amplitude and frequency in plant cells.

The authors compiled and standardized published data on Rubisco dark inhibition for 157 flowering plant species, categorizing them into four inhibition levels and analyzing phylogenetic trends. Their meta‑analysis reveals a complex, uneven distribution of inhibition across taxa, suggesting underlying chloroplast microenvironment drivers and providing a new resource for future photosynthesis improvement efforts.
