Fig. 4From: Quick selenium accumulation in the selenium-rich rice and its physiological responses in changing selenium environmentsExpression patterns of ion transporter genes in roots of seedlings in the presence of exogenous Se. (a) the phosphate transporter gene OsPT2. (b) the Si influx transporter gene OsNIP2;1. (c) the sulfate transporter gene OsSultr1;2. (d) the Cd related transporter gene CAL1. The expression levels were normalized by the reference genes Actin1 and EF1α. Data presents mean ± SE (n = 6)Back to article page
