Inbreeding depression in Solanum carolinense (Solanaceae), a species with a plastic self-incompatibility response [PDF]

open access: yes, 2008
Background Solanum carolinense (horsenettle) is a highly successful weed with a gametophytic self-incompatibility (SI) system. Previous studies reveal that the strength of SI in S. carolinense is a plastic trait, associated with particular S-alleles. The

Self-sterility in the hexaploid Handroanthus serratifolius (Bignoniaceae), the national flower of Brazil

open access: yesActa Botânica Brasílica, 2013
Polyploidization is common among angiosperms and might induce typically allogamous plants to become autogamous (self-compatible, relying on sexual self-fertilization) or apomictic (achieving asexual reproduction through seeds).

Late-acting self-incompatibility in Capparis retusa (Capparaceae), a species of Chaco woodland in NE Argentina [PDF]

open access: yesRevista Brasileira de Botânica, 2000
The reproductive biology of Capparis retusa was studied by means of controlled pollination experiments and fluorescence microscopy observations of post-pollination events. Self-pollinated flowers mostly failed to form fruits despite the fact that self-pollen tubes grew to the ovary and penetrated ovules within 24 h. Since embryo development to globular

Self-incompatibility (S) genotypes of cultivated sweet cherries – An overview update 2020 [PDF]

open access: yes, 2020
The fertility in sweet cherry is determined by a gametophytic self-incompatibility system, controlled by a multi-allelic S locus who prevents self-pollination.

Late‐acting self‐incompatibility–the pariah breeding system in flowering plants [PDF]

open access: yesNew Phytologist, 2014
SummaryIt is estimated that around half of all species of flowering plants show self‐incompatibility (SI). However, the great majority of species alleged to haveSIsimply comply with ‘the inability of a fully fertile hermaphrodite plant to produce zygotes when self‐pollinated’ – a definition that is neutral as to cause.

The effect of sheltered load on reproduction in Solanum carolinense, a species with variable self-incompatibility [PDF]

open access: yes, 2009
In previous studies, we have investigated the strength of self-incompatibility (SI) in Solanum carolinense, a highly successful weed with a fully functional SI system that inhabits early successional and other disturbed habitats.

Transcriptional regulation of Culex pipiens mosquitoes by Wolbachia influences cytoplasmic incompatibility [PDF]

open access: yes, 2013
Cytoplasmic incompatibility (CI) induced by the endosymbiont Wolbachia pipientis causes complex patterns of crossing sterility between populations of the Culex pipiens group of mosquitoes. The molecular basis of the phenotype is yet to be defined.

Reproductive analysis of functional interference and role of pollinators in sunnhemp: A late-acting self-incompatible crop

open access: yes, 2023
Abstract Sunnhemp (C. juncea), a commercially important bast fibre crop possesses late-acting self-incompatibility. The flower is complete, zygomorphic, gamosepalous and herkogamus. Crops with hermaphrodite flowers expressing late-acting self-incompatibility like sunnhemp often encounter sexual interference. The impact of sexual interference in

Effects of self-, chase and mixed self/cross-pollinations on pistil longevity and fruit set in Ceiba species (Bombacaceae) with late-acting self-incompatibility. [PDF]

open access: yesAnn Bot, 2004
Late-acting self-incompatibility (LSI), in which selfed flowers fail to form fruits despite apparently successful growth of the pollen tubes to the ovules, is a contentious and still poorly understood phenomenon. Some studies have indicated pollen tube-pistil interactions, and major gene control.

Sistema reprodutivo do Ipê-Branco: Tabebuia roseo-alba (Ridley) Sandwith (Bignoniaceae) Breeding system of the White Trumpet Tree: Tabebuia roseo-alba (Ridley) Sandwith (Bignoniaceae)

open access: yesActa Botânica Brasílica, 2010
Estudos sobre sistemas reprodutivos têm indicado o predomínio da autoincompatibilidade de ação tardia (AIT) em Bignoniaceae, embora poucas espécies tenham sido investigadas e ocorram outros tipos de sistemas reprodutivos na família.
