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 host range paradox of Meloidogyne incognita: a physiological and transcriptomic analysis of nine susceptible interactions across six plant orders

The study examined infection phenotypes and cross‑kingdom transcriptomes of the root‑knot nematode Meloidogyne incognita across nine host interactions representing six orders of flowering plants 25 days post‑infection. While host phylogeny did not predict parasitic outcomes, the nematode displayed three distinct transcriptional programmes with differential effector deployment, suggesting that host specificity arises from variable effector expression rather than a conserved gall transcriptome.
