Nuclear-cytoplasmic interactions reduce male fertility in hybrids of Arabidopsis lyrata subspecies.

Evolution; international journal of organic evolution - 1 Oct 2011

Leppälä Johanna, Savolainen Outi

Abstract excerpt

We examined the level of postzygotic reproductive isolation in F(1) and F(2) hybrids of reciprocal crosses between the Arabidopsis lyrata subspecies lyrata (North American) and petraea (European). Our main results are: first, the percentage of fertile pollen was significantly reduced in the F(1) and F(2) compared to the parental populations. Second, mean pollen fertility differed markedly between reciprocal...
