Effect of OsHAK5 expression level on rice growth and K accumulated in the absence of external K in the culture solution. Ten-day-old seedlings were grown in IRRI solution containing 1 mm K for 2 weeks, then transferred to a solution without K and allowed to grow for 2 weeks. A and B, OX lines and their wild types. C and D, KO lines and their wild types. A and C, Accumulation of biomass (dry weight) per plant. B and D, Accumulation of K (K concentration and total K content per plant [insets]). Other details are as in Figure 4.
