abstract = {Climate change caused by global warming involves crucial plant growth factors such
as atmospheric CO2 concentration, ambient temperature or water availability. These
stressors usually co-occur, causing intricate alterations in plant physiology and development.
This work focuses on how elevated atmospheric CO2 levels, together with
the concomitant high temperature, would affect the physiology of a relevant crop,
such as broccoli. Particular attention has been paid to those defence mechanisms
that contribute to plant fitness under abiotic stress. Results show that both photosynthesis
and leaf transpiration were reduced in plants grown under climate
change environments compared to those grown under current climate conditions.
Furthermore, an induction of carbohydrate catabolism pointed to a redistribution
from primary to secondary metabolism. This result could be related to a reinforcement
of cell walls, as well as to an increase in the pool of antioxidants in the leaves.
Broccoli plants, a C3 crop, grown under an intermediate condition showed activation
of those adaptive mechanisms, which would contribute to coping with abiotic stress,
as confirmed by reduced levels of lipid peroxidation relative to current climate conditions.
On the contrary, the most severe climate change scenario exceeded the adaptive
capacity of broccoli plants, as shown by the inhibition of growth and reduced
vigour of plants. In conclusion, only a moderate increase in atmospheric CO2 concentration
and temperature would not have a negative impact on broccoli crop yields.},
