Gametophytic Incompatibility inPetunia Hybrida: Molecular Aspects of Male Gametophyte and Female; Sporophyte Interactions

摘要: InPetunia hybrida. the incompatibility reaction is mediated by both haploid genome of male gametophyte and diploid female sporophyte tissues pistil. Pollen carried to stigma surface pistil produced tubes that penetrate grow through style ovary. In plants with a like inPetunia pollen between cells central transmitting tract. These are arranged in longitudinal files, which separated mucilage. The arrest incompatible occurs within tissue (Linakens, 1975). rejection (8–16 hours after self-pollination) accompanied higher sucrose fructose but not glucose levels. Hence compatible absorb more carbohydrates from than tubes. Glucose produces callose deposited tubes, particularly
