A functional study of genes essential for autogamy and nuclear reorganization in Paramecium

open access: yes, 2011
Like all ciliates, Paramecium tetraurelia is a unicellular eukaryote that harbors two kinds of nuclei within its cytoplasm. At each sexual cycle, a new somatic macronucleus (MAC) develops from the germline micronucleus (MIC) through a sequence of complex

APPLE BREEDING PROGRAMS AND METHODS: THEIR DEVELOPMENT AND IMPROVEMENT

open access: yesВавиловский журнал генетики и селекции, 2015
Long-term studies of apple development features allowed breeding intensification and shortening of the time of cultivar development from 36–48 years to 23–27 or even 13–17 years. It is noted that requirements for cultivar are constantly toughened.

Genomic Signatures of North American Soybean Improvement Inform Diversity Enrichment Strategies and Clarify the Impact of Hybridization

open access: yesG3: Genes, Genomes, Genetics, 2016
Crop improvement represents a long-running experiment in artificial selection on a complex trait, namely yield. How such selection relates to natural populations is unclear, but the analysis of domesticated populations could offer insights into the ...

Pollinator limitation, autogamy and minimal inbreeding depression in insect-pollinated plants on a boreal island

open access: yes, 2006
We studied the pollination biology of 18 common insect-pollinated plant species on Kent Island, a boreal island in the Bay of Fundy, New Brunswick, Canada.

Autogamy vs. Allogamy: Biotic-Dependent Populations Reveal Shift in the Reproduction System of an Essentially Autogamous Vanilla

open access: yesDiversity
Flowering plants have evolved a wide range of strategies to avoid self-fertilization. Although allogamy is common among members of the genus Vanilla, V. lindmaniana is widely known for its ability to self-fertilize, resulting in fruit-set rates of 83–100%

Autogamy Among Selected Peach and Nectarine Cultivars

open access: yesJournal of the American Pomological Society, 1983
Self-compatibility and self-fertility in nectarine and peach [ Prunus persica(L.) Batsch] are nearly ubiquitous, except for J. H. Hale and some of its derivatives which produce sterile pollen (4, 5). Self-fertility, although essential may be insufficient for fruit set if there is inadequate transfer of pollen from anther to stigma.
