Patterns of chromosomal variation in natural populations of the neoallotetraploid Tragopogon mirus (Asteraceae)

Chester, M., Riley, R. K., Soltis, P. S., & Soltis, D. E. (2014). Patterns of chromosomal variation in natural populations of the neoallotetraploid Tragopogon mirus (Asteraceae). Heredity.

In this study authors assess chromosomal composition in a natural neoallotetraploid, Tragopogon mirus, and compare it with T. miscellus, which is an allotetraploid of similar age (~40 generations old). They were interested whether parental gene losses in T. mirus correlate with entire or partial chromosome losses. Deviations from parental chromosome additivity within T. mirus individuals  did not reach the levels observed in T. miscellus, but similar compensated changes were observed. The loss of T. dubius-derived genes in two T. mirus individuals did not correlate with any chromosomal changes, indicating a role for smaller-scale genetic alterations.
