Evolution of the mating system in colonizing plants by Pannell, John R.

“…Colonization is likely to be more successful for species with an ability to self‐fertilize and thus to establish new populations as single individuals. As a…”

Evolutionary Transitions Between Hermaphroditism and Dioecy in Animals and Plants by Pannell, John R, Jordan, Crispin Y

“…We review transitions between hermaphroditism and dioecy in animals and (mainly flowering) plants. Although hermaphroditism and dioecy represent two end states…”

On the rarity of dioecy in flowering plants by Käfer, Jos, Marais, Gabriel A. B., Pannell, John R.

“…Dioecy, the coexistence of separate male and female individuals in a population, is a rare but phylogenetically widespread sexual system in flowering plants…”

Kin discrimination allows plants to modify investment towards pollinator attraction by Torices, Rubén, Gómez, José M., Pannell, John R.

“…Pollinators tend to be preferentially attracted to large floral displays that may comprise more than one plant in a patch. Attracting pollinators thus not only…”

Dioecy and chromosomal sex determination are maintained through allopolyploid speciation in the plant genus Mercurialis by Toups, Melissa A, Vicoso, Beatriz, Pannell, John R

“…Polyploidization may precipitate dramatic changes to the genome, including chromosome rearrangements, gene loss, and changes in gene expression. In dioecious…”

The rapid dissolution of dioecy by experimental evolution by Cossard, Guillaume G., Gerchen, Jörn F., Li, Xinji, Cuenot, Yves, Pannell, John R.

“…Evolutionary transitions from hermaphroditism to dioecy have been common in flowering plants,1,2 but recent analysis also points to frequent reversions from…”

A functional decomposition of sex inconstancy in the dioecious, colonizing plant Mercurialis annua by Cossard, Guillaume G., Pannell, John R.

“…Premise Plants with separate sexes often show “inconstant” or “leaky” sex expression, with females or males producing a few flowers of the opposite sex. The…”

Disentangling the effects of jasmonate and tissue loss on the sex allocation of an annual plant by Villamil, Nora, Sommervogel, Benoit, Pannell, John R.

“…Selection through pollinators plays a major role in the evolution of reproductive traits. However, herbivory can also induce changes in plant sexual expression…”

Reduced Responses to Selection After Species Range Expansion by Pujol, Benoit, Pannell, John R

“…Species range expansion reduces genetic variation at the margins of a species range and should thus compromise the adaptive potential of its marginal…”

A Quantitative Genetic Signature of Senescence in a Short-Lived Perennial Plant by Pujol, Benoit, Marrot, Pascal, Pannell, John R.

“…The evolution of senescence (the physiological decline of organisms with age) poses an apparent paradox because it represents a failure of natural selection to…”

High rates of evolution preceded shifts to sex-biased gene expression in Leucadendron , the most sexually dimorphic angiosperms by Scharmann, Mathias, Rebelo, Anthony G, Pannell, John R

“…Differences between males and females are usually more subtle in dioecious plants than animals, but strong sexual dimorphism has evolved convergently in the…”

test of the size-constraint hypothesis for a limit to sexual dimorphism in plants by Labouche, Anne-Marie, John R. Pannell

“…In flowering plants, many dioecious species display a certain degree of sexual dimorphism in non-reproductive traits, but this dimorphism tends to be much less…”
