“…Nicotine has been recognized as the principal additive compound of tobacco that causes devastating health problems and even premature death for tobacco users (Hoffmann et al, 1990 ; Benowitz, 2009 ; Hatsukami et al, 2008 ). Nicotine abuse induces oxidative stress, apoptosis, and inflammation in brain cells (Oliveira-da-Silva et al, 2009 ; Benowitz, 2010 ; Cardinale et al, 2012 ; Motaghinejad et al, 2016 ) and also exacerbates behavioral impairments in mice (Shim et al, 2008 ).…”

“…In all such protocols, the correct choice of pollen germination media (PGM) remains the most important part, as pollen is highly sensitive to the PGM composition (Dafni et al, 2005). To begin with, pollen of several species requires either liquid (Hoffmann et al, 1990;Golan-Goldhirsh et al, 1991;Montaner et al, 2003) or solid (e.g., with addition of agar) medium (Shivanna and Sawhney, 1995;Jayaprakash, 2018) to germinate, while others can germinate in/on both solid and liquid media (Bilderback, 1981;Boavida and McCormick, 2007). Additionally, most pollen grains need a carbohydrate source to germinate successfully, and sucrose solution is generally used (Montaner et al, 2003;Silva et al, 2016;Lagera et al, 2017).…”

The correct choice of in vitro pollen germination media (PGM) is crucial in basic and applied pollen research. However, the methodological gaps (e.g., strong focus of current research on model species and cultivated plants along with the lack of general rules for developing a PGM) makes experimenting with pollen difficult. We closed these gaps by compiling a compendium of optimized in vitro PGM recipes from more than 1800 articles published in English, German, and Russian from 1926 to 2019. The compendium includes 1572 PGM recipes successfully used to germinate pollen grains or produce pollen tubes in 816 species representing 412 genera and 114 families (both monocots and dicots). Among the 110 components recorded from the different PGM recipes, sucrose (89% of species), H3BO3 (77%), Ca2+ (59%), Mg2+ (44%), and K+ (39%) were the most commonly used PGM components. PGM pH was reported in 35% of all studies reviewed. Also, we identified some general rules for creating PGM for various groups of species differing in area of research (wild and cultivated species), phylogenetic relatedness (angiosperms vs. gymnosperms, dicots vs. monocots), pollen physiology (bi- and tri-cellular), biochemistry (starchy vs. starchless pollen grains), and stigma properties (dry vs. wet), and compared the component requirements. Sucrose, calcium, and magnesium concentrations were significantly different across most categories indicating that pollen sensitivity to sugar and mineral requirements in PGM is highly group-specific and should be accounted for when composing new PGM. This compendium is an important data resource on PGM and can facilitate future pollen research.
