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.

Summary Cytokinins promote shoot development, delay leaf senescence, contribute to stress and pathogen responses, and serve as important signals to integrate growth rates throughout the plant. The identification of genes controlling CK synthesis and signaling has allowed us to understand the molecular basis for some of these effects with

ENDOGENOUS CYTOKININS IN MEDICINAL BASIDIOMYCETES MYCELIAL BIOMASS [PDF]
The aim of the research was to study the cytokinins production by medicinal basidial mushrooms. Cytokinins were for the first time identified and quantified in mycelial biomass of six species (Ganoderma lucidum, Trametes versicolor, Fomitopsis ...

Hormonal changes during salinity-induced leaf senescence in tomato (Solanum lycopersicum L.) [PDF]
Leaf senescence is one of the most limiting factors to plant productivity under salinity. Both the accumulation of specific toxic ions (e.g. Na+) and changes in leaf hormone relations are involved in the regulation of this process. Tomato plants (Solanum

Hormonal changes in relation to biomass partitioning and shoot growth impairment in salinised tomato (Solanum lycopersicum L.) plants. [PDF]
Following exposure to salinity, the root/shoot ratio is increased (an important adaptive response) due to the rapid inhibition of shoot growth (which limits plant productivity) while root growth is maintained.

Cytokinins are N (6) substituted adenine derivatives that affect many aspects of plant growth and development, including cell division, shoot initiation and growth, leaf senescence, apical dominance, sink/source relationships, nutrient uptake, phyllotaxis, and vascular, gametophyte, and embryonic development, as well as the response to biotic and ...

Cytokinins and their sugar or non-sugar conjugates are very active growth-promoting factors in plants, although they occur at very low concentrations. These compounds have been identified in numerous plant species.

Cytokinins are important signals that participate in different plant processes, and are well known for their strong influence in plant development. With the years, knowledge has been built about their effects, chemical nature, metabolism, and signaling mechanisms. However, one aspect about cytokinins that has been lagging behind is cytokinin transport.

Role of Cytokinins for Interactions of Plants With Microbial Pathogens and Pest Insects
It has been recognized that cytokinins are plant hormones that influence not only numerous aspects of plant growth, development and physiology, including cell division, chloroplast differentiation and delay of senescence but the interaction with other ...
