Phosphite (Phi) and phosphate (Pi) share the same root uptake system, but Phi acts as a biostimulant that modulates plant growth and disease resistance in a species‑ and Pi‑dependent manner. In Arabidopsis, Phi induces hypersensitive‑like cell death and enhances resistance to Plectosphaerella cucumerina, while in rice it counteracts Pi‑induced susceptibility to Magnaporthe oryzae and Fusarium fujikuroi, accompanied by extensive transcriptional reprogramming.

Prosopis cineraria plants were exposed to two heat stress regimes (45 °C and 55 °C) and subjected to transcriptome sequencing, revealing 1,151 and 1,562 differentially expressed genes respectively, with the higher temperature eliciting a stronger response. Bioinformatic analysis highlighted multiple gene families associated with thermotolerance, and the expression of selected heat‑responsive genes was confirmed by real‑time qPCR, providing candidate loci for crop improvement.

The study examines how the SnRK1 catalytic subunit KIN10 integrates carbon availability with root growth regulation in Arabidopsis thaliana. Loss of KIN10 reduces glucose‑induced inhibition of root elongation and triggers widespread transcriptional reprogramming of metabolic and hormonal pathways, notably affecting auxin and jasmonate signaling under sucrose supplementation. These findings highlight KIN10 as a central hub linking energy status to developmental and environmental cues in roots.
