Gene introgression that involves the transfer of favorable allelic diversity for broadening the genetic base of breeding materials is a powerful 'toolkit' for creating novel allelic combinations during plant sexual reproduction. It is a key factor playing an important role in plant breeding schemes by reintroducing genetic variation at selective sweeps or introgression of desirable traits required for the development of new varieties. Meiosis is a specialized cell division not only enables sexually reproducing organisms to reduce their genomic constituent by half, also provides indefinitely novel combinations of allelic diversity by reshuffling the parental genetic makeup. Crossing over that takes place during prophase-I facilitates the meiotically exchange of genetic materials between homolog pairs as well as their accurate segregations. It is tightly modulated and many intrinsic factors and extrinsic agents are associated with regulation of the process, however, the modulation of meiosis is possible. Although, advanced approaches such as CRIPR/Cas and Virus-Induced gene Silencing (VIGS) have opened new horizons for manipulation of meiotic recombination, distant hybridization could effectively influence the frequency and distribution of homologous (HR) and particularly homoeologous recombination (HeR). In this review, we provide a brief overview of the recent advances in the plant mechanisms for manipulation of HR and HeR employing distant hybridization.
