Description
Sheeba Naaz and Ashverya Laxmi review in 2026 how two opposing energy-sensing pathways help plants survive heavy metal poisoning. Metals such as cadmium, lead, arsenic, and mercury flood cells with oxidative stress and stall growth. The TOR pathway promotes growth when times are good, while SnRK kinases switch the plant into conservation mode.
Under metal stress, SnRK activation turns on defense genes and cellular recycling while throttling TOR to save energy and hold redox balance. The pair also trade signals with calcium, hormone, and stress networks. Understanding their balance could guide breeding or engineering of crops for contaminated soils, a growing need near mines and industry.
