Whole-genome duplications (WGDs) are a prominent process of diversification in
eukaryotes. The genetic and evolutionary forces that WGD imposes on cytoplasmic …

Newly formed polyploids often show extensive meiotic defects, resulting in aneuploid
gametes, and thus reduced fertility. However, while many neopolyploids are meiotically …

Allopolyploids have globally higher fitness than their diploid progenitors; however, by
comparison, most resynthesized allopolyploids have poor fertility and highly unstable …

Saffron crocus (Crocus sativus) is a male-sterile, triploid flower crop, and source of the spice
and colorant saffron. For over three millennia, it was cultivated across the Mediterranean …

Marker assisted breeding, facilitated by reference genome assemblies, can help to produce
cultivars adapted to changing environmental conditions. However, anomalous linkage …

Background Poa annua (annual bluegrass) is an allotetraploid turfgrass, an agronomically
significant weed, and one of the most widely dispersed plant species on earth. Here, we …

Polyploidy results from whole-genome duplication and is a unique form of heritable variation
with pronounced evolutionary implications. Different ploidy levels, or cytotypes, can exist …

Newly formed plant allopolyploids usually have meiosis defect, resulting in chromosomal
instability manifested as variation in chromosome number and/or structure. However, not all …

Common bermudagrass (Cynodon dactylon L.) is an important perennial warm-season
turfgrass species with great economic value. However, the reference genome is still deficient …

Pastures based on perennial monocotyledonous plants are the principal source of nutrition
for ruminant livestock in tropical and subtropical areas across the globe. The Urochloa …
