Vascular Plants :Vascular plants, also known as tracheophytes or higher plants, are a large group of plants have lignified tissues (the xylem) and non-lignified tissue (the phloem). Vascular plants include the clubmosses, horsetails, ferns, gymnosperms and angiosperms....
After formation in roots, the cytokinins move in all directions through the cells of conducting tissues of xylem, phloem, and parenchyma. Apart from plants, cytokinins are produced by smaller organisms like insects, bacteria (e.g. Agrobacterium tumefaciens), fungi (e.g. slime mold), and algae...
What is the major function of the colon? (a) Digestion/absorption (b) Form feces (c) Churning foodstuffs (d) Passageway only (e) Eliminate iron. What are the functions and sources of organic compounds in an organism's body? What is the role of xylem in plants?
1) propagation of chemical agents formed at the site of a stimulus action with the flow of the phloem sap or through the atmosphere (in the case of volatile substances) to other plant parts, 2) a very fast transmission by the xylem in the wave of hydraulic pres...
Waterlogging stands as a common environmental challenge, significantly affecting plant growth, yield, and, in severe cases, survival. In response to waterlogging stress, plants exhibit a series of intricate physiologic, metabolic, and morphologic adaptations. Notably, the gaseous phytohormone ethylene is ...
in PA metabolism. First, we discuss the roles of dual uORFs in theS-adenosylmethionine decarboxylase gene. Second, we summarize the role of the fourth uORF in a basic helix-loop-helix transcription factor gene,SAC51, in thermospermine action in terms of its effect on xylem vessel ...

Interaction of auxin, cytokinin, and gibberellin on cell division and xylem differentiation in cultured explants of Jerusalem artichoke. Dark-cultured explants of parenchymatous cells isolated from Jerusalem artichoke tubers were induced to divide and differentiate as tracheary elements on M... G Dales...
Climate change has posed a significant threat to agricultural productivity in recent years. Due to their sessile nature, plants are vulnerable to various b
In plants, nitric oxide (NO) has been widely accepted as a signaling molecule that plays a role in different processes. Among the most relevant pathways by
