Most individuals of Asclepias exaltata are self-sterile, but all plants lack prezygotic barriers to self-fertilization. To determine whether postzygotic rejection of self-fertilized ovules is due to late-acting self-incompatibility or to extreme, early acting inbreeding depression, we performed three diallel crosses among self-sterile plants related as full-sibs. The full-sibs segregated into four compatibility classes, suggesting that late acting self-incompatibility is controlled by a single… 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
Late‐Acting Self‐Incompatibility in Ipomopsis tenuifolia (Gray) V. Grant (Polemoniaceae)
TLDR
Cross experiments and microscopic analyses were performed on an additional species of Polemoniaceae to examine the evolutionary linkage between genetic control and site of pollen tube inhibition, suggesting that self‐pollination recognition takes place in the ovule, representing a late‐acting SI system.

THE INHERITANCE OF MODIFIERS CONFERRING SELF‐FERTILITY IN THE PARTIALLY SELF‐INCOMPATIBLE PERENNIAL, CAMPANULA RAPUNCULOIDES L. (CAMPANULACEAE)
TLDR
The genetic basis of modifiers conferring self‐fertility in the creeping bellflower, Campanula rapunculoides L. (Campanulaceae), a partially self‐incompatible herb is examined and there is evidence that there may be maternal effects for self-fertility, especially for weakly self‐ incompatible plants. Expand
Evidence for post-zygotic self-incompatibility in Handroanthus impetiginosus (Bignoniaceae)
TLDR
The cytological analysis clearly indicates that ovules of self-pollinated pistils in H. impetiginosus are fertilized before pistil abscission but no embryogenesis initiation occurs, which strongly supports the idea of a post-zygotic self-incompatibility mechanism. Expand
Ovarian self-incompatibility in Narcissus papyraceus (Amaryllidaceae) is the result of a pre-zygotic response
TLDR
Examining the breeding system of Narcissus papyraceus allowed us to rule out the possible effects of pollen–pistil interactions in N. papyracesus as a cause of morph-ratio biases and confirm the exceptional nature of the self-incompatibility mechanism in this polymorphic species. Expand
Late-acting self-incompatibility in Acca sellowiana (Myrtaceae)
TLDR
This study indicates late-acting self-incompatibility occurring through the rejection/abscission of self-pollinated flowers precisely after syngamy and zygote formation in A. sellowiana. 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
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
Late-acting self-incompatibility--the pariah breeding system in flowering plants.

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
Histological study of post-pollination events in Spathodea campanulata beauv. (Bignoniaceae), a species with late-acting self-incompatibility.
TLDR
Self pollen tubes grew successfully to the ovary, penetrating and fertilizing the majority of ovules by 48 h, indicating that S. campanulata is a species with late-acting self-incompatibility. Expand

Population differences in self-fertility in the "self-incompatible" milkweed Asclepias exaltata (Asclepiadaceae).
TLDR
Individual plants of Asclepias exaltata (Asclepiadaceae) typically express an unusual self-incompatibility system under single-gene control, which appears to be under genetic control, as the ability of most plants to set fruit following self-pollinations was identical under natural and greenhouse conditions.

5 Self-incompatibility
TLDR
The chapter describes the members of S-multigene family, an elaborated breeding system for securing outcrossing and maximum recombination in the angiosperms, which is classified into heteromorphic and homomorphic types with respect to flower morphology. Expand
The Evolutionary Significance of Pseudo-Self-Fertility
  • D. Levin

TLDR
Pseudo-self-fertility maximizes the dual advantages of outcrossing and selfing, and is readily increased by selection, although its expression also is influenced by the environment. Expand
BREEDING SYSTEMS IN ASCLEPIAS INCARNATA L., A. SYRIACA L., AND A. VERTICILLATA L.
TLDR
A series of experimental pollinations involving three sympatric species provided strong evidence for physiological and/or genetic barriers to hybridization in Asclepias, and it is suggested that the potential for autogamy, combined with floral mechanisms requiring pollination by insects, insure the advantages of both the genetic variability promoted by outcrossing and the reproductive assurance of uniparental reproduction. Expand
Sequence variability and developmental expression of S-alleles in self-incompatible and pseudo-self-compatible petunia.
TLDR
The data indicate that limited sequence differences may confer allelic specificity, S-locus mRNAs accumulate in a precise organ-specific pattern during floral development, and the ability to inhibit the growth of incompatible pollen tubes appears to require a threshold accumulation of the stylar gene product, along with the participation of as yet undefined pollen gene products.

Incompatibility in Theobroma cacao
TLDR
In an account of the system, Hughes and Babcock have pointed out that their results could not be reconciled with any accepted hypothesis of incompatibility and a new hypothesis would have to be formulated to agree with their results. Expand
The breeding system of desert milkweed, Asclepias subulata
TLDR
It appears that this unusual late-acting form of self-incompatibility, which is characteristic of milkweeds, arose early in the basal Asclepiadaceae/Apocynaceae clade and has been retained in both morphologically plesiomorphic and apomorphic lineages. Expand

TLDR
A number of features of floral morphology and phenology are associated with high Autofertility Indices, but some partially self-incompatible species have considerable autofertility and some self- compatible species have none. Expand

TLDR
The significant among-clone variation suggests that factors intrinsic to the clones strongly affect rates of fertilization and putative penetration in selfand cross-pollinated flowers from three clones of common milkweed. Expand

TLDR
Pollen‐mediated gene flow and infrequent interspecific matings provide mechanisms to lower genetic differentiation among populations to maintain novel, low‐frequency alleles within populations of A. exaltata. Expand
