Cytokinins beyond plants: synthesis by Mycobacterium tuberculosis [PDF]
Mycobacterium tuberculosis (M. tuberculosis) resides mainly inside macrophages, which produce nitric oxide (NO) to combat microbial infections. Earlier studies revealed that proteasome-associated genes are required for M.

Distinct Peculiarities of In Planta Synthesis of Isoprenoid and Aromatic Cytokinins
The biosynthesis of aromatic cytokinins in planta, unlike isoprenoid cytokinins, is still unknown. To compare the final steps of biosynthesis pathways of aromatic and isoprenoid cytokinins, we synthesized a series of nucleoside derivatives of natural ...

Cytokinins and urea derivatives stimulate seed germination in Lotus corniculatus L. [PDF]
We studied the effects of various cytokinins and urea derivatives on germination of aged seeds of in Lotus corniculatus L. The following substances were applied: N6-isoprenoid cytokinins (isopentenyl adenine and zeatin), adenine sulfate, N6-aromatic ...

Interpreting Cytokinin Action as Anterograde Signaling and Beyond
Among the major phytohormones, the cytokinin exhibits unique features for its ability to positively affect the developmental status of plastids. Even early on in its research, cytokinins were known to promote plastid differentiation and to reduce the ...

Cytokinin biosynthesis in cyanobacteria: Insights for crop improvement
Cytokinins, a type of phytohormones that induce division of cytoplasm, have considerable value in agriculture due to their influences on several physiological processes of plants such as morphogenesis, development of chloroplast, seed dormancy, leaf ...
