Nitrogen and Sulfur Effects on Brassica

Nitrogen and Sulfur Effects on Brassica is a research topic within Molecular Biology. Science Explorer counts 8.9k research works in it since 1950. 10.3% of them reached the world's top 10% most cited for their field and year.

This cluster of papers focuses on the molecular functions and regulations of transporters and assimilatory enzymes involved in sulfur metabolism in photosynthetic organisms, particularly in Arabidopsis thaliana. It explores the pathways, regulations, and genetic studies related to sulfur assimilation, sulfate transporters, metabolic responses to sulfur deprivation, and the interplay of biosynthetic pathways under sulfur depletion. Additionally, it delves into the integration of nitrogen management strategies to improve seed yield and oil content in winter oilseed rape, as well as the effects of nitrogen and sulfur on canola yield and nutrient uptake.
