Late-acting self-incompatibility in Asimina triloba: implications for the evolution of self-incompatibility in angiosperms [PDF]

BMC Plant Biology
Background Self-incompatibility (SI) has been reported in many angiosperm species; however, numerous SI systems remain poorly understood, particularly in early-divergent angiosperms where the molecular and genetic regulation of late-acting self ...

Pan-S-locus analysis reveals insights into the origin and evolution of self-incompatibility in the orange subfamily [PDF]

Genome Biology
Background Self-incompatibility is controlled by a highly polymorphic supergene complex, the S-locus, which is structurally complex, rich in repetitive sequences, and varies in length from hundreds of kilobases to tens of megabases across different plant

Dominance in self-compatibility between subgenomes of allopolyploid Arabidopsis kamchatica shown by transgenic restoration of self-incompatibility [PDF]

Nature Communications, 2023
The evolutionary transition to self-compatibility facilitates polyploid speciation. In Arabidopsis relatives, the self-incompatibility system is characterized by epigenetic dominance modifiers, among which small RNAs suppress the expression of a ...

Backcrossing Failure between Sikitita Olive and Its Male Parent Arbequina: Implications for the Self-Incompatibility System and Pollination Designs of Olive Orchards [PDF]

Plants
Backcrossing between Sikitita and its male parent Arbequina, offers the possibility to check the suitability of different self-incompatibility models proposed for olive.

Identification of self-incompatibility alleles in Quince (Cydonia oblonga Mill.). [PDF]

PLoS ONE
The Quince (Cydonia oblonga Mill.), typically known for its self-compatibility, surprisingly presents a degree of self-incompatibility. This research focused on exploring the diversity within the self-incompatibility gene locus (S) in various C.

Transcriptomic Analysis of Self-Incompatibility in Alfalfa [PDF]

Plants
Alfalfa (Medicago sativa L.) is an important forage crop worldwide, but molecular genetics and breeding research in this species are hindered by its self-incompatibility (SI).

Intra- and inter-specific reproductive barriers in the tomato clade

Frontiers in Plant Science, 2023
Tomato (Solanum lycopersicum L.) domestication and later introduction into Europe resulted in a genetic bottleneck that reduced genetic variation.

Identification of Self Incompatibility (S) Alleles in Turkish Apple Gene Sources using Allele-specific PCR

Journal of Agricultural Sciences, 2023
Self-incompatibility (SI) is a genetic mechanism in many flowering plants by which generative reproduction is prevented. The self-incompatibility caused by the genetic functions of the cell is controlled by genes called S genes or self-incompatibility ...

Research Progress on Calcium Ion in Gametophytic Self-Incompatibility

Journal of Horticultural Research, 2022
Calcium ions are involved in plant self-incompatibility response as important signaling substances in cells. In the sporophytic self-incompatibility response, Ca2+ enters the stigma papilla cells and plays a key role in inhibiting incompatible pollen ...

The evolutionary history of plant T2/S-type ribonucleases [PDF]

PeerJ, 2017
A growing number of T2/S-RNases are being discovered in plant genomes. Members of this protein family have a variety of known functions, but the vast majority are still uncharacterized.
