The Makings of Self-Pollination
Science, 2007Plants that produce both male and female gametes use various strategies to determine whether they will predominantly self-fertilize or predominantly use pollen from other flowers. Although compatibility of cell surface receptors is part of the story, the geometry of flower parts also affects what pollen lands on the stigma.

HD-Zip proteins modify floral structures for self-pollination in tomato
ScienceCleistogamy is a type of self-pollination that relies on the formation of a stigma-enclosing floral structure. We identify three homeodomain-leucine zipper IV (HD-Zip IV) genes that coordinately promote the formation of interlocking trichomes at the ...

A self-pollinating mutant of Petunia hybrida
Scientia Horticulturae, 2014Abstract A Petunia hybrida mutant that self-pollinates was identified in an M1 generation of plants mutagenized with ethyl methanesulfonate. A change in floral morphology of the self-pollinating (SP) mutant resulted in flowers with the stigma and anthers in direct contact.

Insect Induced Self-Pollination
Plant Systematics and Evolution, 1984Significant increase of pod production occurs inLupinus palaestinus Boiss. andL. pilosus Murr. following insect visits. The cause of this increase is investigated through (1) examination of the biology of pollination, (2) examination of pod production under various pollination conditions, (3) examination of cross pollination by genetical markers.

Facultative Self-pollination in Island Irises
American Midland Naturalist, 1997-Blue flag (Irzs versicolor) is an insect-pollinated clonal plant found in wet habitats throughout northeastern North America. Our study of an isolated population on Kent Island, New Brunswick, showed that blue flag was self-compatible. Moreover, we found no evidence of inbreeding depression.

Speciation Under Self-Pollination
1999Self-pollination introduces automatically reproductive isolation both between lines (within a species) and between species. It is argued that the reproductive isolation barrier caused by this breeding system affects considerably the mode of speciation in autogamous plants: it frequently substitutes for geographic separation, and facilitates the build ...

Breeding Self-Pollinated Crops
2019As a matter of fact, breeding procedures and schemes differ with the breeding behaviour of a particular species. At the beginning of each breeding programme, the breeder should decide on the type of cultivar to breed for release to farmers. The breeding method used depends on the type of cultivar to be produced. There are basic types of cultivars, viz.,

Breeding Self-Pollinated Crops
1987The challenge of the plant breeder is to develop better varieties. In this chapter we are concerned with the methods by which new varieties of self-pollinated crop plants originate. Before we proceed into a discussion of these methods, let us consider the question, “What is a variety?”
