Agronomy, 2020 Climate change creates challenges for wild species, but plants have survived and adapted to similar changes in their evolutionary past. Most plants were originally outcrossing, one theoretical genetic reason being that self-fertilization does not create ...

Self-pollination by sliding pollen in Caulokaempferia coenobialis (Zingiberaceae) [PDF]
, 2005 Caulokaempferia coenobialis (Zingiberaceae) forms dense populations on steep cliffs in shady, humid monsoon forests in south China. It produces few consecutively opening bright yellow flowers that are 3 cm long and oriented parallel to the ground.

Differential expression of conserved germ line markers and delayed segregation of male and female primordial germ cells in a hermaphrodite, the leech helobdella. [PDF]
, 2013 In sexually reproducing animals, primordial germ cells (PGCs) are often set aside early in embryogenesis, a strategy that minimizes the risk of genomic damage associated with replication and mitosis during the cell cycle.

Création et étude de lignées chez le Pinot noir (Vitis vinifera L.)
OENO One, 1991 L'objectif est l'obtention de génotypes de type « lignée », capables de transmettre à une descendance sexuée les caractères les plus utiles tels que la couleur de la baie dans le cas d'une variété de cuve comme le Pinot noir.

Model of phenotypic evolution in hermaphroditic populations [PDF]
, 2013 We consider an individual based model of phenotypic evolution in hermaphroditic populations which includes random and assortative mating of individuals.

Sex morphs and invasiveness of a fleshy-fruited tree in natural grasslands from Argentina [PDF]
, 2017 Invasiveness has usually been studied as a species-level attribute; nevertheless, phenotypic differences between individuals in a population can lead to significant variations in colonization ability.

Experimental confirmation of protandric simultaneous hermaphroditism in a Caridean shrimp outside of the genus Lysmata [PDF]
, 2008 Caridean shrimps display a variety of sexual systems including gonochorism and various forms of protandry but rarely simultaneous hermaphroditism. Protandric simultaneous hermaphroditism (PSH) has thus far only been demonstrated in the genus Lysmata. The

Reproductive success through high pollinator visitation rates despite self incompatibility in an endangered wallflower [PDF]
, 2016 PREMISE OF THE STUDY: Self incompatibility (SI) in rare plants presents a unique challenge—SI protects plants from inbreeding depression, but requires a sufficient number of mates and xenogamous pollination. Does SI persist in an endangered polyploid? Is
