Název v původním jazyce

Apoplastic and non-secreted cytokinin dehydrogenase from maize: homology and diversity

Popis výsledku v původním jazyce

Plant hormones cytokinins are degraded by a cytokinin dehydrogenase (CKX, EC 1.5.99.12). There are several isoforms of CKX in each plant encoded by a small highly homologous gene family. These isoforms are differentially targeted in plant cells to achieve specific regulatory functions. Differences in local environments affect CKX activity and dictate differences in modes of biochemical action on cytokinin substrates and electron acceptors. Most of the CKX isoforms are localized in apoplast or vacuole; there is generally only one CKX isoform per plant per species that lacks a translocation signal and presumably functions in cytoplasm. The best characterized CKX from maize is ZmCKX1, known to be secreted into the apoplast, while a gene encoding the non-secreted CKX has not been cloned before. The aims of this work were to clone the gene for non-secreted CKX from maize (nsZmCKX), compare its localization with the apoplastic ZmCKX1 and characterize its biochemical and structural properties
