Plants, 2020 In most species of Pleurothallidinae, the self-incompatibility site occurs in the stylar canal inside the column, which is typical of gametophytic self-incompatibility (GSI).

Frontiers 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]
PLoS 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

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

Acta 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–the pariah breeding system in flowering plants [PDF]
New 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.

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

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]
Ann 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.

, 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

Acta 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.
