In many plants --- such as the apple, peach, cherry, poplar, &c.
The Natufians, an Epipaleolithic culture located in the Levant, possessed stone sickles and intensively collected many plants, such as wild barley (Hordeum spontaneum).
Another influence is the varying length of darkness and light throughout the year, so that many plants, such as chrysanthemums, have a strong photoperiodism.
In many plants, such as grasses and lettuce, the outer integument and ovary wall are completely fused, so seed and fruit form one entity; such seeds and fruits can logically be described together as "dispersal units," or diaspores.
This strategy has been demonstrated in many plants, such as Arabidopsis (Schneeberger et al. 2009), rice (Abe et al. 2012; Wambugu et al. 2017), soybean (Song et al. 2017), wheat (Trick et al. 2012), pigeon pea (Singh et al. 2016), sunflower (Livaja et al. 2013) and sorghum (Han et al. 2015), and it has identified some QTLs and genes for important traits.
Many plants, such a junipers, oleanders, trees and 90% of shrubs, can easily get by with being watered once a month or less.
Many industrial plants such as textile factories, fertilizer industry, mining facilities and tanneries discharge wastewater containing many kinds of heavy metals including mercury.
Many agricultural plants, such as wheat and rice, can be stored as chilled or frozen seed.
Many desert plants, such as stoneplants (Lithops; Aizoaceae) and aloe (Aloe; Asphodelaceae), develop succulent leaves for water storage.
This self-seeds easily enough, but many other plants (such as Lychnis coronaria) are grown from seed or cuttings before being planted out.
The efficacy of the CRISPR/Cas9 system has been proven in both model plants and many crop plants, such as rice, sorghum, wheat, maize, sweet orange, soybean, potato, apple, and tomato18,19,20.
