A new case of late-acting self-incompatibility in Capparis L. (Brassicaceae): C. jacobinae Moric. ex Eichler, an endemic andromonoecious species of the Caatinga, Pernambuco State, Brazil Novo registro de auto-incompatibilidade de ação tardia em Capparis (Brassicaceae): C. jacobinae Moric. ex Eichler, uma espécie andromonóica endêmica da Caatinga, PE, Brasil [PDF]

open access: yesActa Botânica Brasílica, 2009
We studied the reproductive system of Capparis jacobinae Moric ex Eichler (Brassicaceae), based on controlled hand-pollination and observation of pollen tube growth made in a fluorescence microscope.

Does Late-acting Self-incompatibility (LSI) Show Family Clustering? Two More Species of Bignoniaceae with LSI:Dolichandra cynanchoides and Tabebuia nodosa [PDF]

open access: yesAnnals of Botany, 1999
Abstract By means of hand pollination experiments and fluorescence microscopy the breeding systems and pollen tube growth were studied in Dolichandra cynanchoides and Tabebuia nodosa , two bignoniaceous species of the Chaco woodland of NE Argentina.

Reproductive modes in populations of late-acting self-incompatible and self-compatible polyploid Ludwigia grandiflora subsp. hexapetala in western Europe

open access: yesPeer Community Journal
Reproductive mode, i.e., the proportion of individuals produced by clonality, selfing and outcrossing in populations, determines how hereditary material is transmitted through generations. It shapes genetic diversity and its structure over time and space,

Evidência da atuação do sistema de auto-incompatibilidade tardia em Acca Sellowiana (berg) burret. (Myrtaceae) Evidence of the late-acting self-incompatibility system in Acca Sellowiana (berg) burret. (Myrtaceae)

open access: yesRevista Brasileira de Fruticultura, 2007
Acca sellowiana (Myrtaceae) é uma frutífera nativa da região Sul do Brasil e nordeste do Uruguai, que vem despertando grande interesse devido ao alto potencial organoléptico de seus frutos.

Late-acting self-incompatibility and a narrow floral tube as selective forces for stylar dimorphism in Narcissus (Amaryllidaceae): A response to Simón-Porcar

open access: yesIdeas in Ecology and Evolution, 2018
Simón-Porcar proposes an alternative origin in the evolutionary pathway to heterostyly as described in a model proposed by Lloyd and Webb. Below I summarize her key points and namely consider the implications of comparing her model to ideas within the ...

HT-B and S-RNase CRISPR-Cas9 double knockouts show enhanced self-fertility in diploid Solanum tuberosum

open access: yesFrontiers in Plant Science, 2023
The Gametophytic Self-Incompatibility (GSI) system in diploid potato (Solanum tuberosum L.) poses a substantial barrier in diploid potato breeding by hindering the generation of inbred lines.

A temporal dimension to the influence of pollen rewards on bee behaviour and fecundity in Aloe tenuior. [PDF]

open access: yesPLoS ONE, 2014
The net effect of pollen production on fecundity in plants can range from negative--when self-pollen interferes with fecundity due to incompatibility mechanisms, to positive--when pollen availability is associated with increased pollinator visitation and

A Systematic Search for RNase-based Self-incompatibility [PDF]

open access: yes, 2022
Most flowering plant species have co-sexual individuals whose own pollen often lands on their own stigmas. And yet, approximately one-half are self-incompatible---they cannot self-fertilize.

Late-acting self-incompatible system, preferential allogamy and delayed selfing in the heteromorphic invasive populations of Ludwigia grandiflora subsp. hexapetala [PDF]

open access: yesPeer Community Journal, 2021
A bstract Breeding system influences local population genetic structure, effective size, offspring fitness and functional variation. Determining the respective importance of self- and cross-fertilization in hermaphroditic flowering plants is thus important to ...

Linkage disequilibrium and recombination rate estimates in the self-incompatibility region of Arabidopsis lyrata [PDF]

open access: yes, 2007
Genetic diversity is unusually high at loci in the S-locus region of the self-incompatible species of the flowering plant, Arabidopsis lyrata, not just in the S loci themselves, but also at two nearby loci.
