Description
Yessica San Miguel and colleagues test in 2026 whether fungi that live inside desert plants can lend their heat tolerance to tomato. Rising temperatures flood plant tissues with reactive oxygen species, damaging growth, and tomato is especially sensitive. Tomato plants were inoculated with one of two desert-derived endophytic fungi, Talaromyces minioluteus or Serendipita indica, and grown at normal or heat-stress temperatures of 35 degrees by day.
Heat cut growth and raised oxidative damage, but inoculated plants fared better on both counts. They kept higher shoot and root biomass. They also carried less of the damage marker malondialdehyde and less hydrogen peroxide. Their antioxidant defenses ran stronger, including the enzymes superoxide dismutase, catalase, and ascorbate peroxidase plus extra phenolic compounds. The two fungi did not protect identically, which the authors use to argue for matching fungal partners to crops as heat intensifies.
