“…They have various functions related to biotic and abiotic stress responses (Yang et al, 2006;Cho et al, 2008;Trujillo et al, 2008;Liu et al, 2011), hormonal responses (Luo et al, 2006;Raab et al, 2009), self-incompatibility (Liu et al, 2007;Samuel et al, 2008Samuel et al, , 2009, and seed germination (Bergler and Hoth, 2011;Salt et al, 2011). U-box E3s also have cellular functions within a diverse group of monocot and dicot model crops, such as Brassica spp., Medicago spp., rice (Oryza sativa), tobacco (Nicotiana tabacum), and tomato (Solanum lycopersicum) plants (Gu et al, 1998;Stone et al, 1999Stone et al, , 2003Zeng et al, 2004Zeng et al, , 2008GonzĂĄlez-Lamothe et al, 2006;Vega-SĂĄnchez et al, 2008;Bos et al, 2010;Mbengue et al, 2010;Park et al, 2011b), suggesting that they are widely conserved in the plant kingdom.…”
