Native Australian seedlings exhibit novel strategies to acclimate to repeated heatwave eventsNARA Subscribed
Heatwaves are becoming more intense and frequent. Plant photosystem thermal thresholds can vary with species, but also shift in response to environmental triggers. Both upper and lower thresholds can acclimate to repeated heatwaves through ecological stress memory, where prior exposure primes them for subsequent events. The extent to which acclimation to repeated heat stress events varies among environmental origin and/or spec...
Beyond a single temperature threshold: Applying a cumulative thermal stress framework to plant heat toleranceNARA Subscribed
Most plant thermal tolerance studies focus on single critical thresholds, which limit the capacity to generalise across studies and predict heat stress under natural conditions. In animals and microbes, thermal tolerance landscapes describe the more realistic, cumulative effects of temperature. We tested this in plants by measuring the decline in leaf photosynthetic efficiency ( F V / F M ) following a combination of temperatu...
