A recent quantitative genetics study on seed size in Arabidopsis lyrata suggested that selfish parental genes may interact to determine seed size based on a recognition system (Willi 2013, Am. Nat.). Currently, I test the hypothesis that this interaction happens between two important imprinted genes determining seed size, MEDEA (maternally expressed, growth suppressing) and PHERES1 (paternally expressed, growth promoting).
Besides, I perform paternity analysis in the species Arabidopsis arenicola to reveal its mating system.
