COMMENTARY 
LITERATURE
SOURCE
-
the vascular tissue and medullary region of sepals and petals show slight activity of CKX
at early flowering: TaCKX7b and TaCKX8, at late flowering: TaCKX4
-
in the stalk of the leaf branched glandular trichomes, the CKX activity is restricted to the stalk region only, and is not present in the secretory head
additional information
-
first foliage leaves are cut of and kept in water in the darkness which results in a high increase in CKX activity
-
diurnal variation. Maximal activity 3 h after the dark-light transition and during the diminishing of the midday cytokinin peak
-
involvement of cytokinin oxidase/dehydrogenase in regulation of cytokinin levels in leaves
lower CK content and higher enzymatic activity in cv. Manuela leaves compared with cv. Scinado
-
35 kDa isozyme CKX35 in chlorotic leaves associated with a reduction in representative cytokinin levels and high H2O2 concentrations, and 37 kDa isozyme CKX37 in green leaves associated with representative CKs and H2O2 at normal levels
-
35 kDa isozyme CKX35 in chlorotic leaves associated with a reduction in representative cytokinin levels and high H2O2 concentrations, and 37 kDa isozyme CKX37 in green leaves associated with representative CKs and H2O2 at normal levels
-
cv. Manuela has a higher endogenous cytokinin content and slightly lower enzyme activity than cv. Scinado
highest activity in root nodule, very low enzyme level in R50 mutant compared with wild type
-
after removal of roots, no cytokinin oxidase activity remains after 24 h
-

enzyme activity during vegetative development of plants
additional information
-
the enzyme activity is not detected in the epidermal layers of leaf, stem and root, but the epidermal outgrowth and the leaf trichome show prominent CKX activity
