additional information
-
lower enzyme activity in seedling grown on 0.002 mM iron than in plants grown on 0.022 or 0.045 mM iron, leaves of plants grown without iron become chlorotic within 6 weeks, lack of iron decreases the leaf chlorophyll index and iron concentration in recently matured leaves
-
lower enzyme activity in seedling grown on 0.002 mM iron than in plants grown on 0.022 or 0.045 mM iron, lack of iron decreases the leaf chlorophyll index and iron concentration in recently matured leaves. Iron level in nutrient solution has no effect on fresh and dry weight
-
expression of isoforms AtFRO2, AtFRO3, AtFRO5. Expression of AtFRO3 is elevated in iron-deficient plants. When copper is limited, expression of AtFRO3 is induced, predominantly in the vascular cylinder of roots
-
excised root tips, enzyme activity is markedly increased by iron deficiency and by presence of Cd2+ or Pb2+
-
higher basal enzyme activity than Vaccinium corymbosum, little effect of iron deficiency on enzyme activity
-
significant increase in enzyme activity under iron-deficient conditions
-
expression of isoforms AtFRO3, AtFRO8. Expression of AtFRO3 is elevated in iron-deficient plants. When copper is limited, expression of AtFRO6 is reduced, of AtFRO3 is induced
-
isoform AtFRO6 is specifically expressed in green-aerial tissues in a light-dependent manner. Both light and cell differentiation are required for expression
additional information
-
isoforms AtFRO6, AtFRO7 show high expression in all green parts of the plant
additional information
-
enzyme content is very high in carob in the absence of Fe and is decreased sharply even when only a low level of Fe is present in the nutrient solution
additional information
-
enzyme content is low in the absence or with high levels of Fe, its highest values occur in roots exposed to a low level of Fe
