Theoretical and Applied Genetics, 1992 In recent years a large number of reports have been published hinting about the possible role of selection at the male gametophyte level in natural conditions and its possible use as a tool in plant breeding programs. In this work, the evidence that has so far emerged on gametophytic selection is reviewed, and its relationship to pollen competition ...

Pollenkitt is associated with the collectability of Malvoideae pollen for corbiculate bees
Journal of Pollination Ecology, 2023 Pollen grains of Malvoideae (Malvaceae) which corbiculate bees cannot collect constitute a floral filter that excludes pollen-collecting bumble bees and honey bees from exploiting pollen resources.

Advances in Plant Regeneration: Shake, Rattle and Roll
Plants, 2020 Some plant cells are able to rebuild new organs after tissue damage or in response to definite stress treatments and/or exogenous hormone applications. Whole plants can develop through de novo organogenesis or somatic embryogenesis.
