PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1476-1499, September 2026.Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Restorer-of-Fertility Mutations Recovered in Transposon-Active Lines of S Male-Sterile Maize
G3: Genes, Genomes, Genetics, 2018 Mitochondria execute key pathways of central metabolism and serve as cellular sensing and signaling entities, functions that depend upon interactions between mitochondrial and nuclear genetic systems.

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1563-1566, September 2026.Many plant species worldwide are struggling to regenerate due to the ongoing effects of climate change. These effects appear to be further exacerbated by the loss of keystone megafauna, which were important seed dispersers. By identifying the traits commonly seen in seeds spread by modern elephants, it is possible to predict which species likely ...

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1567-1571, September 2026.Dust, a common form of air pollution, is particularly problematic on roadsides, which are important habitats for plants and pollinators. We investigated whether and how road dust affects plant sexual reproduction using Primula chungensis in a biodiversity hotspot. Our study provides compelling evidence that road dust can harm plant reproductive success

Effects of water stress on male gametophyte development in plants
, 1997 Male reproductive development in plants is highly sensitive to water deficit during meiosis in the microspore mother cells. Water deficit during this stage inhibits further development of microspores or pollen grains, causing male sterility.

YAO is a nucleolar WD40-repeat protein critical for embryogenesis and gametogenesis in Arabidopsis
BMC Plant Biology, 2010 Background In flowering plants, gametogenesis generates multicellular male and female gametophytes. In the model system Arabidopsis, the male gametophyte or pollen grain contains two sperm cells and a vegetative cell. The female gametophyte or embryo sac
