Plant Sugar-Response Pathways. Part of a Complex Regulatory Web

Plant sugar-response pathways. Part of a complex regulatory web.

In addition to playing a central role in metabolism, soluble sugars such as Glc and Suc help regulate many developmental and physiological processes in plants (for review, see Koch, 1996; Smeekens, 1998; Sheen et al., 1999; Yu, 1999). For example, sugar levels have been postulated to play an important role in determining the time at which some plant species flower. Treatments that induce flower...

Genetic approaches to understanding sugar-response pathways.

Plants as photoautotrophic organisms are able to produce the carbohydrates they require and have developed mechanisms to co-ordinate carbohydrate production and its metabolism. Carbohydrate-derived signals regulate the expression of genes involved in both photosynthesis and metabolism, and control carbohydrate partitioning. A number of genetic approaches have been initiated to understand sugar-...

SnapShot: Plant Immune Response Pathways

Recognition of Microbe/Pathogen-Associated Molecular Patterns Plant innate immunity depends on the timely discrimination of self from nonself, which, as in animal cells, can be accomplished by membrane-anchored pattern recognition receptors (PRRs). These receptors monitor the exterior space for microbe/pathogen-associated molecular patterns or MAMPs (also called PAMPs) by binding to them direct...

Sugar and phytohormone response pathways: navigating a signalling network.

Many plant developmental, physiological and metabolic processes are regulated, at least in part, by nutrient availability. In particular, alterations in the availability of soluble sugars, such as glucose and sucrose, help regulate a diverse array of processes. Multiple lines of evidence indicate that many of these processes are also regulated in response to other signalling molecules, such as ...
