Cytological Evidence For Gametophytic Self-Incompatibility In The Genus Veronica, Romain Scalone, Dirk Albach
Cytological Evidence For Gametophytic Self-Incompatibility In The Genus Veronica, Romain Scalone, Dirk Albach
Turkish Journal of Botany
The self-incompatibility (SI) of 3 Middle East Veronica species (V. filiformis, V. gentianoides, V. teucrium) is studied, for the first time, by pollination and pollen tube growth experiments. Cytological observations of the self-pollen tubes within the pistils permit a conclusion about the presence of a gametophytic SI system in the first 2 species. The investigated population of the third is self-compatible and confirms the facultative trait of its self-sterility. The presence of a gametophytic SI system in 2 of them suggests the putative conservation of this SI system within the genus Veronica (Plantaginaceae) and could be related to the well-known …

Plasticity And Within Plant Sex-Ratio Variation In Monoecious Emex Spinosa, Regina Berjano, Montserrat Arista, María Talavera, María Jesús Ariza, Pedro Luis Ortiz
Turkish Journal of Botany
Understanding how phenotype trait expression varies at different levels of biological organization is crucial to understanding the fundamental ecological, evolutionary, and developmental issues that contribute to adaptive plasticity. This is particularly important in plants because of their modular organization. Here, we study plasticity in flower production in response to light intensity at 3 levels of biological organization (between populations, among individuals, and within individuals) in Emex spinosa (L.) Compd., a Mediterranean amphicarpic annual. Plants exposed to high light intensity grew faster and produced more flowers than plants at low light intensity. Female flower production was the most labile trait. Within …
