Two inbreds of Zea mays, tolerant to K^+ deficiency and control, were grown in the presence of different concentrations of K^+. Several parameters were compared between the two inbreds and characteristic differences in terms of K^+ utilization were observed. 1. The dry weight of both inbreds was nearly the same in the presence of a sufficient concentration of K^+, but was apparently higher in the tolerant inbred than the control inbred according to the decreasing amount of K^+ supply. 2. Symptoms of K^+ deficiency in the tolerant inbred appeared only with complete absence of K^+, but those in the control inbred could be observed even at a decreased level of K^+ supply. 3. The increased length of the main root and top to root ratio in the control inbred were conspicuously lower than those of the tolerant inbred due to K^+ deficiency. Furthermore, the amout of lateral roots of the cotrol inbred was approximately one-half to one-fourth of that of the tolerant inbred. 4. The capability of K^+ absorption by the roots treated for K^+ deficiency was higher in the tolerant inbred than in the controel inbred. The difference in the capability became larger when assayed with decreasing concentrations of K^+. 5. K^+-dependent H^+ extrusion from roots treated for K^+ deficiency was larger in the tolerant inbred than in the control inbred.

Mugineic acids are a group of compounds having ferric chelating activity. They are secreted from the roots of some gramineous plants under iron deficiency. These compounds play an important role in the acquisition of insoluble iron from soils by the gramineous plants. In the present study, the biosynthetic pathways of five mugineic acids were investigated in different gramineous plants using feeding experiments with ^<13>-and/or ^2H-labeled compounds and by NMR techniques. The results revealed that L-Met serves as a precursor for all mugineic acids tested. All mugineic acids share the pathway from L-Met to 2'-deoxymugineic acid although subsequent steps differ and are dependent on the plant species and cultivars. In oats, avenic acid A is biosynthesized from 2'-deoxymugineic acid by cleavage of the azetidine ring. In barley, hydroxylation at the C-2' position in 2'-deoxymugineic acid yields mugineic acid. Further hydroxylation at the C-3 position in mugineic acid produces 3-epihydroxymugineic acid and hydroxymugineic acid in beer barley and rye, respectively. All mugineic acids were found to have similar effect on iron uptake, suggesting that 2'-deoxymugineic acid is a key phytosiderophore. The biosynthetic pathway between L-methionine and 2'-deoxymugineic acid was investigated by observing the incorporation of label from ^<13>C, ^2H, and ^<15>N-labeled methionine in wheat roots (Triticum aestivum L. cv Minori). As a result, only the deuterium atom from the C-2 position of L-methionine was lost, while other atoms were completely incorporated when three molecules of methionine were converted to 2'-deoxymugineic acid. These observations are consistent with the conversion of L-methionine to azetidine-2-carboxylic acid, suggesting that L-methionine is first converted to azetidine-2-carboxylic acid during biosynthesis leading to 2'-deoxymugineic acid. Based on these results, a hypothetical pathway from L-methionine to 2'-deoxymugineic acid was postulated.
