Histone Demethylases ELF6 and JMJ13 Antagonistically Regulate Self-Fertility in Arabidopsis [PDF]

open access: yesFrontiers in Plant Science, 2021
The chromatin modification H3K27me3 is involved in almost every developmental stage in Arabidopsis. Much remains unknown about the dynamic regulation of this histone modification in flower development and control of self-fertility.

Medically Defined Infertility Versus Self-Perceived Fertility Problem: Implications of Survey Wording for Assessing Associations with Depressive Symptoms

open access: yesWomen's Health Reports, 2020
Objective: To examine how measures of infertility based on medical criteria and based on self-perception relate to depressive symptoms among women with infertility. Background: Survey-based studies of depressive symptoms have used either measures of self-

Effect of a Nurse-Led Smartphone-Based Self-Tracking Program on Women's Fertility Awareness for the Appropriate Use of Infertility Treatment [PDF]

open access: yesEgyptian Journal of Health Care, 2023
Background: Self-tracking tools and practices can be thought as forms of "technology forthe self" that allow people to monitor, control, act upon, and optimize their bodies in accordancewith standards of appearance and health.

OCCURRENCE OF THE SELF-FERTILE PHENOTYPE OF Phytophthora infestans IN EL-BEHERA GOVERNORATE, EGYPT [PDF]

open access: yesJournal of Plant Protection and Pathology, 2002
A survey for the self-fertile phenotype of Phytophthora infestans was conducted during the 1999·2001 growing seasons. Blighted potato were sampled from fields in different localities (EI-Rahmania, Housh Eissa, Kafr EI·Dawar, and Kafr EI-Zayat) in EI ...

Self-Fertilization and the Evolution of Recombination [PDF]

open access: yesGenetics, 2005
Abstract In this article, we study the effect of self-fertilization on the evolution of a modifier allele that alters the recombination rate between two selected loci. We consider two different life cycles: under gametophytic selfing, a given proportion of fertilizations involves gametes produced by the same haploid individual, while ...

Balancing selection in self‐fertilizing populations [PDF]

open access: yesEvolution, 2021
Self-fertilization commonly occurs in hermaphroditic species, either occasionally or as the main reproductive mode. It strongly affects the genetic functioning of a population by increasing homozygosity and genetic drift and reducing the effectiveness of recombination.

Identifying Pollen Donors and Success Rate of Individual Pollinizers in European Plum (Prunus domestica L.) Using Microsatellite Markers

open access: yesAgronomy, 2020
European plum cultivars (Prunus domestica L.) are hexaploid and partially self-fertile or self-sterile requiring compatible pollinizers with overlapping bloom times. Therefore, inter-planting of different pollinizer cultivars is recommended.

PARASITES AND THE EVOLUTION OF SELF-FERTILIZATION [PDF]

open access: yesEvolution, 2001
Assuming all else is equal, an allele for selfing should spread when rare in an outcrossing population and rapidly reach fixation. Such an allele will not spread, however, if self-fertilization results in inbreeding depression so severe that the fitness of selfed offspring is less that half that of outcrossed offspring.

Blooming phenology and fertility of sour cherry cultivars selected in Hungary

open access: yesInternational Journal of Horticultural Science, 2002
Experiments were conducted during the period between 1972 and 2002 at three sites in Hungary. At Érd 97, Helvetia 10, and Újfehértó, 3 cultivars were studied in variety collections.
