Sulfur assimilation is the process by which living organisms incorporate sulfur into their biological molecules. [1] In plants, sulfate is absorbed by the roots and then transported to the chloroplasts by the transipration stream where the sulfur are reduced to sulfide with the help of a series of enzymatic reactions .

Assimilation is the process of converting inorganic sulfur into organic sulfur present in an organism. This assimilatory process is intimately linked to mineralization. In fact, these two processes, assimilation and mineralization, occur simultaneously.

2018年7月26日 · In this mini-review, we introduce updated comprehensive information about sulfur assimilation in microorganisms, including this topic. Also, we introduce recent advances of the application study about l-cysteine overproduction, including the GlpE overexpression.

2011年8月1日 · Sulfur assimilation and production of sulfur-containing compounds are essential biological activities that play critical roles in many biological processes, including the role of sulfur containing compounds such as glutathione and phytochelatin …

Sulfate (Sulfur) assimilation takes place chiefly in leaves in chloroplasts. The sulfate absorbed by roots from soil solution is translocated through xylem to shoots for assimilation. To some extent sulfate assimilation may also occur in roots in proplastids.

2014年10月28日 · The pathway of sulfate assimilation, which provides plants with the essential nutrient sulfur, is tightly regulated and coordinated with the demand for reduced sulfur. The responses of metabolite concentrations, enzyme activities and mRNA levels to various signals and environmental conditions have been well described for the pathway.

Sulfur assimilation in plants begins with uptake of sulfur in the form of sulfate from the soil and then movement into the shoot via a group of low- and high- affinity sulfate transporters. In Arabidopsis, there are 14 sulfate transporters classed into five groups based on sequence similarity and function [39].

This review provides up-to-date knowledge in functions and regulations of sulfur assimilation in plants and algae, focusing on sulfate transport systems and metabolic pathways for sulfate reduction and synthesis of downstream metabolites with diverse biological functions.

In this mini-review, we introduce updated comprehensive information about sulfur assimilation in microorganisms, including this topic. Also, we introduce recent advances of the application study about L-cysteine overproduction, including the GlpE overexpression.

2019年5月24日 · Here we review the coordination of sulfate, nitrate, and carbon assimilation, and show how they are altered in C 4 plants. We then summarize current knowledge of the mechanisms of coordination of these pathways.
