| Outline of Final Research Achievements |
Sulfur is an essential macronutrient for plants, and its deficiency significantly affects the growth. Soil sulfur deficiency has been found to be an important factor that constrains the development of appropriate rice cultivation practices in the floodplain of northern Ghana. Such sulfur deficient soils are also reported to be widespread in West Africa. In this study, several rice cultivars were grown in sulfur deficient soils. We found that the growth of DJ123 was not retarded compared with other varieties in sulfur deficient soils. To characterize rice cultivars sulfur-responsive genes, a transcriptome analysis of Nipponbare, IR64, and DJ123 was conducted using microarrays. In addition, we used principal component analysis (PCA) to compare the sulfur-responsive genes and selected on representative sulfur-responsive genes with PCA loading. We found that the levels of several gene transcripts were significantly higher in DJ123 than in Nipponbare and IR64 in sulfur deficient soils.
