Strong thermal acclimation of photosynthesis in tropical and temperate wet‐forest tree species: the importance of altered Rubisco content

Abstract: Understanding of the extent of acclimation of light-saturated net photosynthesis (A ) to temperature (T), and associated underlying mechanisms, remains limited. This is a key knowledge gap given the importance of thermal acclimation for plant functioning, both under current and future higher temperatures, limiting the accuracy and realism of Earth system model (ESM) predictions. Given this, we analysed and modelled T-dependent changes in photosynthetic capacity in 10 wet-forest tree species: six from temperate… Show more

“…As a proxy for Rubisco content, we analysed leaf nitrogen content, but we did not find consistent patterns with growth temperature, probably because photosynthesis at optimum temperature did not change systematically, as it did for most species in Scafaro et al (2017).…”

“…The lower V cmax per unit N of tropical species could reflect less leaf N allocated to photosynthetic proteins. This was suggested in comparisons between plants adapted to warm and cool environments, in both field and glasshouse settings (Xiang et al ., ; Ali et al ., ; Dusenge et al ., ; Bahar et al ., ; Scafaro et al ., ). In turn, this implies that a greater fraction of leaf N could be allocated to nonphotosynthetic components (e.g.…”

“…Berry & Björkman, ; Hikosaka et al ., ; Way & Yamori, ). This has also been demonstrated for tropical tree species (Kositsup et al ., ; Slot & Winter, ; Scafaro et al ., ), but there are several open questions about thermal acclimation of photosynthesis in tropical forests. First, will P Opt increase or decrease when T Opt increases in response to warming?…”
