Breynia<\/em> belongs to the Phyllanthaceae, Malpighiales. In Arabidopsis thaliana var2<\/em> mutant, white leaves are formed because of the delay of chloroplast development. Chloroplasts gradually differentiate from proplastids and leaves gradually turn to be in green (Sakamoto et al. 2009). VAR2<\/em> gene encodes a proteinase and degradation of some proteins is necessary for proper chloroplast development (Liu et al. 2010). Breynia<\/em> is not so closely related to Arabidopsis thaliana<\/em>, but their variegated leaves may be formed with similar mechanisms.<\/p>\n
