Male fertility advantage within and between seasons in the perennial androdioecious plant Phillyrea angustifolia by Laugier, F, Saumitou-Laprade, P, Vernet, P, Lepart, J, Cheptou, P-O, Dufay, M

“…Androdioecy, the co-occurrence of males and hermaphrodites, is a rare reproductive system. Males can be maintained if they benefit from a higher male fitness…”

Temporal dynamics of sexual dimorphism in a dioecious species by Moquet, L, Lateur, L, Jacquemart, A-L, De Cauwer, I, Dufay, M

“…Sexual dimorphism for floral traits is common in dioecious plant species. Beyond its significance for understanding how selection acts on plant traits through…”

Modelling the maintenance of male-fertile cytoplasm in a gynodioecious population by Dufay, M, Touzet, P, Maurice, S, Cuguen, J

“…Gynodioecy is the co-occurrence of females and hermaphrodites in populations. It is usually due to the combined action of cytoplasmic male sterility (CMS)…”

Impact of plant flowering phenology on the cost/benefit balance in a nursery pollination mutualism, with honest males and cheating females by DUFAY, M

“…This study documents the flowering phenology and its potential consequences on a nursery pollination mutualism between a dioecious plant, in which honest male…”

Dioecy is associated with higher diversification rates in flowering plants by Käfer, J., Boer, H. J., Mousset, S., Kool, A., Dufay, M., Marais, G. A. B.

“…In angiosperms, dioecious clades tend to have fewer species than their nondioecious sister clades. This departure from the expected equal species richness in…”

Genetic determination of male sterility in gynodioecious Silene nutans by Garraud, C, Brachi, B, Dufay, M, Touzet, P, Shykoff, J A

“…Gynodioecy, the coexistence of female and hermaphrodite plants within a species, is often under nuclear-cytoplasmic sex determination, involving cytoplasmic…”

Variation in pollen production and pollen viability in natural populations of gynodioecious Beta vulgaris ssp. maritima: evidence for a cost of restoration of male function by DUFAŸ, M, VAUDEY, V, DE CAUWER, I, TOUZET, P, CUGUEN, J, ARNAUD, J.-F

“…Gynodioecious species are defined by the co-occurrence of two clearly separated categories of plants: females and hermaphrodites. The hermaphroditic category…”

Atomic step motion during the dewetting of ultra-thin films by Pierre-Louis, O., Chame, A., Dufay, M.

“…We report on three key processes involving atomic step motion during the dewetting of thin solid films: (i) the growth of an isolated island nucleated far from…”
