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).

Different Flowering Strategies Ensure Reproductive Success in Two Coexisting Self-Incompatible Orchids. [PDF]
Ecol EvolThis study compares the reproductive strategies of two self‐incompatible orchids, Pholidota articulata (mass‐flowering) and Coelogyne prolifera (steady‐state flowering). Despite differences in pollinator visitation and pollinia transfer efficiency—higher in P. articulata—both species achieved similar natural fruit set rates over 3 years.

Toward in vitro fertilization in Brachiaria spp. [PDF]
, 2010 Brachiaria are forage grasses widely cultivated in tropical areas. In vitro pollination was applied to accessions of Brachiaria spp. by placing pollen of non-dehiscent anthers on a solid medium near isolated ovaries.

Review of the molecular background of self-incompatibility in rosaceous fruit trees
International Journal of Horticultural Science, 2006 This review gives a presentation of the gametophytic self-incompatibility system in the roscaeous fruit trees. Studies to discover the pistil (S-ribonucleases) and pollen-part components (F-box molecules) are summarized and models for the self ...

Plants, 2022 This paper reviews the progress and the way ahead in diploid F1 hybrid potato breeding by comparisons with expectations from the theory of inbreeding and crossbreeding, and experiences from other diploid outbreeding crops.

DNA-based S-genotyping of Japanese plum and pluot cultivars to clarify incompatibility relationships [PDF]
, 2007 Diploid japanese plum (Prunus salicina Lindl.) cultivars are commonly self-incompatible. To date, 14 incompatibility alleles (S-alleles) have been identified and labeled with alphabetical (S-a-S-n) and 5 with numeric codes (S-1, S-3-S-6).

Gametophytic self-incompatibility re-examined: a reply [PDF]
Heredity, 1985 In principle, as has long been known, there are two ways by which the stigmas or styles of the flowers of self-incompatible species could discriminate between incompatible and compatible pollen, for either the growth of the former would be inhibited (the oppositional hypothesis) or that of the latter stimulated (the complementary hypothesis).

Transcriptome analysis reveals self-incompatibility in the tea plant (Camellia sinensis) might be under gametophytic control [PDF]
, 2016 BACKGROUND: Self-incompatibility (SI) is under genetic control and prevents inbreeding depression in angiosperms. SI mechanisms are quite complicated and still poorly understood in many plants.

When gametophytic self-incompatibility meets gynodioecy
Genetics Research, 2008 SummaryThe occurrence of gynodioecy among angiosperms appears to be associated with self-compatibility. We use individual-based simulations to investigate the conditions for breakdown of a gametophytic self-incompatibility system in gynodioecious populations and make a comparison with hermaphroditic populations where the conditions are well known.

From recognition to response: integrated signaling pathways determining pollen acceptance and rejection in Brassicaceae. [PDF]
New PhytolSummary Generation of competent offspring is vital for the prosperity of flowering plants. The pistil not only functions as a conduit for pollen tubes to grow to the ovary but also provides a selective venue for facilitating the growth of compatible pollen tubes and discouraging invaders and incompatible pollen.
