Flaminia, a self-incompatible peach variety: Short communication
This study showed that the peach variety Flaminia is self-incompatible in Northern Greece, and it produces fruits only after cross fertilization.

The evolution of recombination in self-fertilizing organisms [PDF]
Abstract Cytological data from flowering plants suggest that the evolution of recombination rates is affected by the mating system of organisms, as higher chiasma frequencies are often observed in self-fertilizing species compared with their outcrossing relatives.

Purging deleterious mutations under self fertilization: paradoxical recovery in fitness with increasing mutation rate in Caenorhabditis elegans. [PDF]
The accumulation of deleterious mutations can drastically reduce population mean fitness. Self-fertilization is thought to be an effective means of purging deleterious mutations. However, widespread linkage disequilibrium generated and maintained by self-

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-fertility in Pseudomonas aeruginosa [PDF]
SUMMARY: Two interfertile strains of Pseudomonas aeruginosa were re-examined for evidence of self-fertility. One strain was self-fertile, the frequency of recombination being affected by the manner in which the parent organisms were grown before being combined. The other strain gave no evidence of self-fertility.

Création et étude de lignées chez le Pinot noir (Vitis vinifera L.)
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.

Cannabis sativa L. (hemp, marijuana) produces male and female inflorescences on different plants (dioecious) and therefore the plants are obligatory out-crossers.

BackgroundThe population of infertile couples receiving in vitro fertilization and embryo transfer in China is increasing gradually. The association of self-esteem and dyadic coping of infertile couples undergoing in vitro fertilization and embryo ...

Mitochondrial respiration and Ca2+ waves are linked during fertilization and meiosis completion [PDF]
Fertilization increases both cytosolic Ca(2+) concentration and oxygen consumption in the egg but the relationship between these two phenomena remains largely obscure.

Protandry and Self-Fertilization in the Calyptraeidae [PDF]
ORTON1 suggested that protandrous animals might be self-fertilizing and that this would be advantageous for the spread of a species. He concluded that Crepidula fornicata was self-fertilizing because he found an isolated female guarding veliger larvae. I have kept single Crepidula in aquaria and they have laid fertilized spawn two to three months later.
