Global Environment and Propulsion Plant

Global aspects of C/N interactions determining plant-environment interactions.

The atomic C:N ratio in photolithotrophs is a function of their content of nucleic acids, proteins, lipids, polysaccharides, and other organic materials, and varies from about 5 in some protein-rich microalgae to much higher values in macroalgae and in higher plants with relatively more structural and energy storage materials. These differences in C:N ratios among organisms means that there is ...

Legume transcription factors: global regulators of plant development and response to the environment.

Transcription factors (TFs) are DNA-binding proteins that interact with other transcriptional regulators, including chromatin remodeling/modifying proteins, to recruit or block access of RNA polymerases to the DNA template. Plant genomes devote approximately 7% of their coding sequence to TFs, which is a testament to the complexity of transcriptional regulation in these organisms. Extensive seq...

An Archaeobotanical Perspective on Environment, Plant Use, Agriculture, and Interregional Contact in South and Western Iran

Plant remains from archaeological sites reflect many aspects of the relationship between people, plants, and the environmentin which they lived. Plant macroremains—seeds and wood that are visible without a microscope—can address a widerange of questions. The most basic include what crops were grown? What was used for fuel? Do any of the plants comefrom distant lands? Examples from fourth and th...
