Co-segregation of the
gynomonoecious sex form1 gene (gsfl) of Tripsacum dactyloides (Poaceae) with molecular markers.
In Tetramolopium, species are either monoecious or
gynomonoecious but self-compatible in either case (Lowrey 1986).
More than 93% of the monoecious taxa have green flowers (p<0.0001, Table II), and green and yellow flowers are predominant in both
gynomonoecious and dioecious species.
A disproportionate number of
gynomonoecious species are herbaceous (N = 25, Table 1), primarily because of 19 species of Lipochaeta (Asteraceae).
The female bias expected with protandry, for example, could manifest itself by hermaphroditic flowers opening earlier than male flowers in andromonoecious plants, female flowers opening earlier than hermaphroditic flowers in
gynomonoecious plants (Pellmyr 1987), or early-opening hermaphroditic flowers allocating most of their resources to female functions, and later-opening flowers allocating more resources to male functions (Brunet 1990).
The mutant was given the assignment GSF-1, indicating its
gynomonoecious phenotype (Dewald and Dayton, 1985).
