Aegilops species have significantly contributed to wheat breeding despite the difficulties
involved in the handling of wild species, such as crossability and incompatibility. A number …

Key message Although Ae. tauschii has been extensively utilised for wheat breeding, the D-
genome-containing allopolyploids have largely remained unexploited. In this review, we …

Polyploidy plays an important role in crop improvement. Polyploid plants, particularly those
produced through unreduced gametes (2 n gametes), show increased organ size, improved …

Abstract Background and Aims During the analysis of plant male meiocytes coming from
destroyed meiocyte columns (united multicellular structures formed by male meiocytes in …

The potential for gene flow between cultivated species and their weedy relatives poses
agronomic and environmental concerns, particularly when there are opportunities for the …

It has been reported that F1 LA hybrids could produce a small number of functional 2 n eggs
regardless of their male sterility, however, there are very little similar phenomena reported in …

Background Unreduced gametes, a driving force in the widespread polyploidization and
speciation of flowering plants, occur relatively frequently in interspecific or intergeneric …

Mutations and natural selection have been the cornerstone of plant evolution. Mutations
have also played a significant role in crop domestication and plant breeding. Defined as …

Key message Epidendrum produces 2 n gametes with high frequency. This paper is the first
to report on multiple pathways for forming 2 n gametes, meiotic defeats, and pre-meiotic …

Background Unreduced gamete formation during meiosis plays a critical role in natural
polyploidization. However, the unreduced gamete formation mechanisms in Triticum …
