Classifications of Transgenic Crops. Transgenic crops, economically important plants that have their genomes edited often with foreign DNA, have been developed for the betterment of agriculture, increased crop yield, and crop improvement in general. Over the years, the 5 distinct categories of transgenic crops that have been commercialized are Herbicide-Tolerance, Insect-Resistance, Abiotic-Stress-Tolerance, Disease-Resistance, and Nutritional Enhancement in Crops (Yamamoto and McLaughlin, 1981; Geliebter et al., 1983; Broadway and Duffey, 1986; Hilder et al., 1987; McPherson et al., 1988; Perlak et al., 1991; Marc and Dennis, 1995; Padgette et al., 1995; Duan et al., 1996; Wehrmann et al., 1996; Takabe et al., 1998; Ye et al., 2000; Schönbrunn et al., 2001; Chen and Murata, 2002; Ferreira et al., 2002; St-Onge and Jones, 2003; Rizhsky et al., 2004; Al-Babili and Beyer, 2005; Paine et al., 2005; Ariel et al., 2007; Fang et al., 2007; Gao et al., 2007; Yan et al., 2007; Castiglioni et al., 2008; Dill et al., 2008; Kereša et al., 2008; Ufaz and Galili, 2008; Khan et al., 2009; Food and Agriculture Organization of the United Nations, 2010; Majeed et al., 2011; Pollegioni et al., 2011; Green, 2012; Rahman et al., 2012; Tuteja et al., 2012; James, 2013; Rasmussen et al., 2013; Gupta et al., 2015; Singh et al., 2015; Brookes and Barfoot, 2017; Perotti et al., 2017; Brookes and Barfoot, 2018; Raza et al., 2019; Brookes and Barfoot, 2020a; ISAAA, 2020a; Brookes and Barfoot, 2020b; ISAAA, 2020b; Kumar et al., 2020; Brookes, 2022; ISAAA, 2022; World Health Organization, 2023).
