AI Article Synopsis
- The study examined the impact of four types of foliar iron fertilizers on the iron content and nutritional quality of polished rice.
- Foliar application at the anthesis stage proved most effective, with DTPA-Fe notably enhancing iron concentration, sulfur content, and beneficial cysteine levels while reducing phosphorus and phytic acid.
- DTPA-Fe also improved overall rice quality by maintaining amylase, protein, and mineral levels, making it a recommended option for iron biofortification efforts.
Article Abstract
The present study compared the effects of four different forms of foliar iron (Fe) fertilizers on Fe concentration, bioavailability and nutritional quality of polished rice. The results showed that foliar fertilisation at the anthesis stage was an effective way to promote Fe concentration and bioavailability of polished rice, especially in case of DTPA-Fe. Compared to the control, foliar application of DTPA-Fe increased sulphur concentration and the nutrition promoter cysteine content, whereas decreased phosphorus concentration and the antinutrient phytic acid content of polished rice, as a result increased 67.2% ferrtin formation in Caco-2 cell. Moreover, foliar DTPA-Fe application could maintain amylase, protein and minerals quality of polished rice. According to the current study, DTPA-Fe is recommended as an excellent foliar Fe form for Fe biofortification program.

Characterization of a Major Quantitative Trait Locus for the Whiteness of Rice Grain Using Chromosome Segment Substitution Lines.
Plants (Basel)

Key Laboratory of Plant Functional Genomics of the Ministry of Education/Zhongshan Biological Breeding Laboratory, Yangzhou University, Yangzhou 225009, China.
The whiteness of rice grains (WRG) is a key indicator of appearance quality, directly impacting its commercial value. The trait is quantitative, influenced by multiple factors, and no specific genes have been cloned to date. In this study, we first examined the correlation between the whiteness of polished rice, cooked rice, and rice flour, finding that the whiteness of rice flour significantly correlated with both polished and cooked rice.

A diet rich in anthocyanins can benefit human health against a broad spectrum of human diseases due to the high antioxidant activities of anthocyanins. Enrichment of anthocyanins in the starchy endosperm of rice is an effective solution to provide nutritional food in human diets. However, previous attempts failed to engineer anthocyanin biosynthesis in the rice endosperm by transgenic expression of rice endogenous genes.

Prolonged consumption of foods containing toxic metals can elevate the risk of noncommunicable diseases, including chronic kidney disease of uncertain etiology (CKDu). Despite the increasing number of CKDu cases in Maradankulama and Mahakanadrawa Grama Niladhari Divisions (GN) in Sri Lanka, no prior studies have examined the accumulation of heavy metal(loid)s and their potential association with CKDu prevalence. Furthermore, there is an absence of comprehensive analyses using chemometric techniques such as PCA and hierarchical studies regarding CKDu and heavy metal contamination in Sri Lanka.

Article Synopsis
- - Rice is a vital food crop with a significant impact on global nutrition, and the study highlights the importance of rice bran as a potential dietary supplement for improving health and addressing nutrient deficiencies.
- - The issue of arsenic contamination in rice products is critically discussed, as it poses serious health risks, including cancer and developmental problems, while the review underscores the lack of regulatory guidelines for harmful substances like aflatoxins and arsenic.
- - The analysis also explores the nutritional benefits and bioactive compounds in rice bran, particularly in pigmented varieties, promoting its use for health advantages such as cancer prevention and anti-diabetic effects.
A holistic field experimental inquiry into cadmium's migration and translocation dynamics across the entire growth spectrum of five Japonica rice cultivars.

The contamination of farmland soils with cadmium (Cd) poses a substantial threat to agricultural productivity, food security and safety, and ultimately human health. However, little research has been done on the Cd transport mechanisms in highly Cd polluted soil via field experiment. This study, from a field-scale perspective, examines the migration and transformation features of Cd throughout the growth cycle of five (C1, C2, C3, C4, H1) Japonica rice cultivars in Jiangsu Province, China.
