In most self-incompatible (SI) plants, pollen tube growth in self-pollinated flowers is inhibited on the stigma or in the style. SI systems that operate in the ovary have been assumed to be extremely rare. Evidence from many plant species is presented to show that the SI barriers in the ovary, described here as late-acting SI systems, are quite common. The late-acting SI systems are divided into four categories: (1) ovarian inhibition of incompatible pollen tubes before the ovule is reached; (2… Expand

  • P. Gibbs

TLDR
The case for recognition of LSI as having a widespread occurrence and as a mechanism that inhibits selfing and promotes outbreeding in many plant species is argued. Expand
Breeding systems in Clivia (Amaryllidaceae): late-acting self-incompatibility and its functional consequences
Late-acting (ovarian) self-incompatibility, characterized by minimal or zero seed production following self-pollen tube growth to the ovules, is expected to show phylogenetic clustering, but canExpand
Is Eucalyptus Cryptically Self-incompatible?
TLDR
The present observations suggest that, in addition to a late-acting self-incompatibility barrier, cryptic self- incompatibility could be a mechanism responsible for the preferential out-crossing system in these two eucalypt species. Expand
Methods for Determining Compatibility and Pollinator Efficiency in Temperate Fruit Species
TLDR
The most commonly used methods for testing self-incompatibility and pollinator efficiency in the main fruit trees are described. Expand
Floral biology and late-acting self-incompatibility in Jacaranda racemosa (Bignoniaceae)
TLDR
Investigation of the floral biology and the breeding system in Jacaranda racemosa Chamisso and the histology of post-pollination events indicated the occurrence of a kind of late-acting self-incompatibility in which the processes of ovule penetration, fertilisation and endosperm initiation were slower in selfed than in crossed pistils. Expand
Self-sterility in flowering plants: preventing self-fertilization increases family diversification rates.
TLDR
Analysis of the distribution and frequency of self-sterility in flowering plants and sister comparisons point to the importance of SS, particularly pre-zygotic SI in the evolution of flowering plants. Expand
Breeding systems in Cyrtanthus (Amaryllidaceae): variation in self-sterility and potential for ovule discounting.
TLDR
Variation in breeding systems among Cyrtanthus species is revealed and the potential for gender conflict in self-sterile species in which ovules are penetrated and disabled by pollen tubes from self-pollen is highlighted. Expand
Pollen tube growth and self-incompatibility in three Ziziphus species (Rhamnaceae)
TLDR
A comparative analysis of fluorescence microscopy observations of pollen tube growth following controlled cross pollinations of emasculated flowers and self-pollinations of non-emasculated Flowers in three Ziziphus species suggests that the self-incompatibility system operating in the studied ZizIPhus species is gametophytically controlled.

The Role of Late-Acting Self-Incompatibility and Early-Acting Inbreeding Depression in Governing Female Fertility in Monkshood, Aconitum kusnezoffii
TLDR
Results indicated that the embryos were aborted at different stages due to the expression of many deleterious alleles throughout the genome during seed maturation, which contributed to the reduction in selfed seed set in A. kusnezoffii. Expand
Do s genes or deleterious recessives control late-acting self-incompatibility in Handroanthus heptaphyllus (Bignoniaceae)? A diallel study with four full sib progeny arrays.
TLDR
A genetic model postulating a single S locus with four s alleles, one of which, in the maternal parent, is dominant to the other three, will produce RCI, RCC and NRC situations each at 33 %, consistent with the diallel results. Expand

Differences between Self-Incompatibility and Self-Sterility
TLDR
The term ‘voluntarily self-sterile’ is proposed to describe Lotus plants that fail to set seed when isolated from insects and ‘artificially self-styled’ when they still fail toset self-seed following artificial self-pollination. Expand

Physiological self-incompatibility (SI) is one of the most common mechanisms by which outcrossing is promoted in the angiosperms (East, 1940; Whitehouse, 1950; Nettancourt, 1977). ConsiderableExpand

The relationships of self-sterility to self-incompatibility in this genus, the evolution of this mechanism, and evidence that similar mechanisms are found in other legumes are discussed. Expand
Pollination Sub-Systems Distinguished by Pollen Tube Arrest after Incompatible Interspecific Crosses in Rhododendron (Ericaceae)

Both the site of pollen tube arrest within the pistil, and the error syndrome of tip growth and callose deposition anomalies, are characteristic of each interspecific cross. Expand
SELF‐INCOMPATIBILITY SYSTEMS IN THE RUBIACEAE OF A TROPICAL LOWLAND WET FOREST
TLDR
The objective of the study was to estimate the proportion of self-compatible and self-incompatible species in a sample of Rubiaceae from one community, and to determine the site in the pistil at which self-pollen is inhibited in the self- incompatible species. Expand
Self‐incompatibility in Ranunculus acris L.
TLDR
The incompatibility system in the dicot Ranunculus acris was examined because the family, Ranunculaceae, presumably has an evolutionary basis in common with the monocots, and studies in F1-families showed that at least three multiallelic S-loci govern the incomp compatibility system. Expand

Natural populations of Narcissus tazetta L. series bicolores Baker have been found in Israel to consist of plants having two floral types: short-styled and long- Styled, and crosses between plants of the same floral type were found to be fertile. Expand
Gametophytic Self-Incompatibility Reexamined
TLDR
An alternative hypothesis which incorporates many loci and complementary pollen-style interactions suggests that there may be no S gene, as previously thought, and that gametophytic self-incompatibility is perhaps merely one aspect of extensive pollen- style interactions. Expand
