Molecular mechanisms of self-incompatibility in Brassicaceae and Solanaceae [PDF]

Proceedings of the Japan Academy. Series B, Physical and Biological Sciences
Self-incompatibility (SI) is a mechanism for preventing self-fertilization in flowering plants. SI is controlled by a single S-locus with multiple haplotypes (S-haplotypes).

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 ...

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.

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 ...

Incompatible pollen tubes in the quince style and their impact on fertilization success

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2023
Self-incompatibility presents one of the challenges in modern fruit production. It can be correlated with a lower yield of self-incompatible cultivars which also demand the planting of the pollinisers.

Preventing self-fertilization: Insights from Ziziphus species

Frontiers in Plant Science, 2023
The fitness of self-progeny individuals is inferior to that of their outcrossed counterparts, resulting in a reduction in a plant population’s ability to survive and reproduce.

Self-Incompatibility of Camellia weiningensis Y.K. Li.

Horticulturae, 2022
This study compared the pollen tube growth, fruit setting, and seed setting characteristics of Camellia weiningensis Y.K. Li. under self- and cross-pollination to identify its self-incompatibility characteristics and types. C.

Two Self-Incompatibility Sites Occur Simultaneously in the Same Acianthera Species (Orchidaceae, Pleurothallidinae)

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).

Bud pollination and other techniques are ineffective in breaking late-acting self-incompatibility in Ceiba chodatii (Malvaceae - Bombacoideae)

Acta Botânica Brasílica, 2021
There are two homomorphic self-incompatibility (SI) mechanisms among flowering plants - gametophytic self-incompatibility (GSI) and sporophytic self-incompatibility (SSI).
