Neue Studie zeigt, dass sich Bäume an wechselnde Temperaturen gewöhnen

…to a point

> Although past research has elucidated the mechanisms of rubisco under elevated CO2 concentrations and increased temperatures, our understanding of how/if photorespiration, downstream of rubisco, acclimates to these environmental changes is limited.

> Accumulation of H2O2, a signaling molecule involved in both stress and developmental processes, leads to cell death when catalase-deficient Nicotiana tabacum mutant plants were exposed to high photorespiratory pressure31. Managing these intermediates is thus important to maintain plant vigor, especially in changing environments where photorespiratory influx is highly dynamic.

> Photorespiratory influx can change in short- (seconds to days) or long-term (weeks-years) time scales depending on the growth environment.
