Preservation of cultivar purity is a particular challenge for plants that are self-incompatible and have easily germinating seeds and vigorously spreading rhizomes.
Spatial spread of genetically identical plants may decrease paternal diversity and fertility, particularly towards the centre of large clumps of clones.
There is emerging evidence that some C4 eudicots involve the photosynthetic enzyme PEP-CK in carbon acquisition alongside other decarboxylation enzymes.
Although elastic similarity models and determinations of critical buckling height often consider density-specific stiffness to be constant, few studies have tested this assumption in plantation-grown trees.
