Leaf respiration in the dark and its C isotopic composition (δ(13) CR ) contain information about internal metabolic processes and respiratory substrates. δ(13) CR is known to be less negative compared to potential respiratory substrates, in partic

Recent advances in understanding the metabolic origin and the temporal dynamics in delta(13)C of dark-respired CO(2) (delta(13)C(res)) have led to an increasing awareness of the importance of plant isotopic fractionation in respiratory processes. Pro

Despite the known biochemical production of a range of aromatic compounds by plants and the presence of benzenoids in floral scents, the emissions of only a few benzenoid compounds have been reported from the biosphere to the atmosphere. Here, using

Organs of C3 plants differ in their C isotopic signature (d 13 C). In general, leaves are 13 C-depleted relative to other organs. To investigate the development of spatial d 13 C patterns, we induced different C allocation strategies by reducing ligh

The magnitude of diurnal variation in carbon isotopic composition of leaf dark respired CO2correlates with the difference between δ13C of leaf and root material.
