How do tree growth rings, species and climate interact? A study into xylogenesis in Annals of Botany takes a closer look.
A mismatch between the thresholds of temperature and moisture for the onset of xylogenesis may increase forest vulnerability in semi-arid areas under forecasted warmer and drier conditions.
A study of Arabidopsis transcription factors finds that AR-formation and xylogenesis are inversely related but involve fine-tuning by the same proteins.
Bagniewska-Zadworna et al. study the differentiation of tracheary elements (TEs) in pioneer roots of Populus trichocarpa grown in rhizotrons.
The length of the growing season and the resulting amount of growth could respond differently to climate change.
