Neo-polyploid infertility associated with defective pollen tube growth
Plant Science Research WeeklyPolyploidy, 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…
The urban environment led to unintended adaptive evolution in plants (Science)
Plant Science Research WeeklyGenerally, evolution is driven by natural selection, but not always. Human activities lead to the creation of unique niches, and other organisms must adapt accordingly. Cities are unique niches that are significantly different from rural areas and natural conditions. The urban habitat provides plants…

Why does telomere length vary in plants?
The Plant Cell: In a NutshellChoi et al. uncover the association between telomere length and flowering time variation in Arabidopsis, rice, and maize. The Plant Cell (2021) https://doi.org/10.1093/plcell/koab022
Background: Telomeres are DNA-protein complexes found at the ends of eukaryotic chromosomes that protect the…
Genomic mechanisms of climate adaptation in polyploid bioenergy switchgrass (Nature)
Plant Science Research WeeklySwitchgrass (Panicum virgatum) is a tall, perennial species native to the prairies of North America. Switchgrass is well-known for its uses as a biofuel and forage crop. However, switchgrass is also a fascinating model to investigate how plants adapt to changing environments, as historical glacial cycles…
Arabinogalactan-proteins of Zostera marina L. contain unique glycan structures and provide insight into adaption processes to saline environments (Sci. Reports)
Plant Science Research WeeklySeagrasses are fascinating examples of adaptation. Like dolphins and other sea mammals, they are marine-dwelling descendants of species that had fully adapted to life on land. To survive submerged in saltwater has necessitated morphological, anatomical and physiological adaptations. Recent genome analysis…
