Thiophenes on Mars: Biotic or Abiotic Origin?

Abiotic and biotic stress combinations.

Environmental stress conditions such as drought, heat, salinity, cold, or pathogen infection can have a devastating impact on plant growth and yield under field conditions. Nevertheless, the effects of these stresses on plants are typically being studied under controlled growth conditions in the laboratory. The field environment is very different from the controlled conditions used in laborator...

Abiotic and biotic elicitors’ effects on secondary metabolites biosynthesis of periwinkle (Catharanthus roseus (Linn.) G. Don)

Based on recent statistical survey, the cancer is the third important factor in Iran mortality. Vinblastine and vincristine alkaloids are dominantly biosynthesized in the aerial parts of periwinkle, broadly applied for cancer treatment. Therefore, over production of these alkaloids by using the biotechnological approaches is inevitable. Since the terpenoid indole alkaloids (TIAS) biosynthesis p...

Tritrophic Interactions Across Biotic and Abiotic Gradients

Responses to previous reviews This LTREB proposal was submitted in January, 2008 and was not funded. The reviewer and panel comments were very helpful in drafting a revision and in contemplating the long-term research goals of the PI. All reviewer comments prompted changes in this proposal; the most notable concerns and criticisms (italicized and shortened) from the panel summary are directly a...

Biotic and Abiotic Interactions in Ecosystems

Biotic and Abiotic Interactions in Ecosystems Plants live in complex environments where many biotic and abiotic factors limit or promote productivity and carbon biosequestration. Temperature and water extremes, nutrient and other resource availabilities, microbeinduced diseases, and insect attacks can limit plant productivity. At the same time, this productivity intimately depends on plant inte...
