Webb17 apr. 2013 · Self-incompatibility (SI) is one of the important factors that can result in seedless fruit in Citrus. However, the molecular mechanism of SI in Citrus is not yet clear. In this study, two suppression subtractive hybridization (SSH) libraries (forward, F and reverse, R) were constructed to isolate differentially expressed genes in pollen from … WebbSelf-incompatibility (SI) is a genetically controlled mechanism to prevent self-fertilisation, ensuring genetic diversity of offspring. Three SI systems have been well characterised at …

WebbThe Pistil, Megasporangium (ovule) and Embryo sac The gynoecium represents the female reproductive part of the flower. The gynoecium may consist of a single pistil (monocarpellary) or may have more than one pistil (multicarpellary). f When there are more than one, the pistils may be fused together (syncarpous) or may be free (apocarpous) .

WebbThe Papaver SI system utilises a receptor–ligand type interaction that triggers a calcium-dependent signalling network culminating in the programmed cell death of incompatible pollen. In the S-RNase SI system, some form of detoxification of the ribonuclease activity takes place in compatible pollen tubes. Key Concepts Webb1 apr. 2014 · It was proposed that pollen tube MYBs respond to the pistil environment and in turn activate the expression of genes critical for pollen tube reception signaling (Leydon et al., 2013;Leydon et al ...
