Mechanisms of unreduced gamete formation in Arabidopsis thaliana
, 2019 Polyploidy is a widespread phenomenon in plants, which is commonly believed to arise through the production of unreduced (2n) gametes due to meiotic failure. Despite the importance of unreduced gamete formation for plant polyploidization, the mechanisms leading to their formation are not well understood. Previous work of our group indicated that JASON (

Polyploidy among plant species extraneous in Indiana [PDF]
, 1950 This study was undertaken for the purpose of determining whether there is any relationship between polyploidy and geographic distribution with special reference to species extraneous in a given area.

Sources of genetic variation in unreduced gamete production in a mixed-ploidy plant
, 2021 Unreduced gametes, the primary cause of polyploid formation, are considered maladaptive; however, their frequency and genetic variation among natural populations is rarely measured. Using the perennial, mixed-ploidy plant, Chamerion angustifolium, I investigated the magnitude and two sources of variation in unreduced gamete production: elevation and ...

Induction of Unreduced Gamete in Phalaenopsis by N_2O Treatments
Induction of Unreduced Gamete in Phalaenopsis by N_2O TreatmentsWe attempted to induce unreduced gamete of Phalaenopsis by arresting the meiotic process with nitrous oxide gas (N_2O). Phalaenopsis amabilis and P. equestris (2n=2x=38) were treated with nitrous oxide gas under pressure for 0, 24, 48 and 68 hrs. The treatments for 24 and 48 hrs induced unreduced gamete in P.
