Neo-polyploid infertility associated with defective pollen tube growth
Polyploidy, arising from whole-genome duplication, is a common phenomenon in plant species. However, newly formed polyploids are often infertile and the mechanism(s) by which they adapt to their new karyotypes remain unclear. In this article, Westermann and colleagues chemically induced the formation of tetraploid Arabidopsis arenosa plants from diploid parents. They found that the lower […]
