Article Abstract
Measurements of rice physical traits, such as length, width, and percentage of filled/unfilled grains, are essential steps of rice breeding. A new approach for measuring the physical traits of rice grains for breeding purposes was presented in this study, utilizing image processing techniques. Backlight photography was used to capture a grayscale image of a group of rice grains, which was then analyzed using a clustering algorithm to differentiate between filled and unfilled grains based on their grayscale values. The impact of backlight intensity on the accuracy of the method was also investigated. The results show that the proposed method has excellent accuracy and high efficiency. The mean absolute percentage error of the method was 0.24% and 1.36% in calculating the total number of grain particles and distinguishing the number of filled grains, respectively. The grain size was also measured with a little margin of error. The mean absolute percentage error of grain length measurement was 1.11%, while the measurement error of grain width was 4.03%. The method was found to be highly accurate, non-destructive, and cost-effective when compared to conventional methods, making it a promising approach for characterizing physical traits for crop breeding.

Grain size substantially influences rice quality and yield. In this study, we identified (), a quantitative trait locus encoding an F-box protein that enhances grain length by promoting cell proliferation. The transcription factor OsbZIP35 represses expression, while COR1 interacts with OsTCP19, leading to its degradation.

Rice is consumed by ∼50% of the global population, grown primarily in flooded paddy fields, and is susceptible to arsenic accumulation. Inorganic arsenic, particularly in reduced form (As(III)), is considered the most toxic and is more likely to accumulate in rice grains under flooded systems. We postulate that increased levels of highly reactive iron minerals, such as ferrihydrite, in paddy soils can regulate the bioavailability of arsenic and reduce its uptake by priming iron plaque formation.

Plants balance resource energy allocation between growth and immunity to ensure survival and reproduction under limited availability. This study reveals that rice cultivars with elevated sucrose levels boost resistance to the fungal pathogen Magnaporthe oryzae by accumulating the phytoalexin sakuranetin, regulated by the transcription factor STOREKEEPER (OsSTK). OsSTK binds to the promoter region of OsNOMT (Naringenin-7-O-Methyltransferase) to drive sakuranetin biosynthesis.

Background: The objective of this study was to compare the effects of daily consumption of white potatoes compared with white rice on cardiometabolic health in individuals with type-2 diabetes (T2D).
Objective: To determine the effects of white potato consumption compared to white rice (a commonly consumed refined grain) on indices of glycemic control and cardiovascular health in individuals with overweight or obesity and T2D.
Methods: In this randomized crossover study, comparative control trial, 24 adults with T2D [45-80 y, body mass index (kg/m) 25-40] consumed baked white potatoes (100 g) or calorie-matched white rice (75 g) daily for 12 wk, separated by a 2-wk washout, with assessments of glycemic control, lipids, inflammation, blood pressure, endothelial function, and body composition at baseline (only 1 baseline visit included as a covariate in statistical analyses), 6 wk, and 12 wk.

Red yeast rice (RYR) is an Asian indigenous medicine that ferments grains using the Monascus fungi, specifically . Monacolins, pigments, phenols, sterols, and benzopyrans, such as the mycotoxin citrinin, were proven to be present in RYR, contributing to its numerous effects. This study aims to provide a thorough overview of the in vitro and in vivo pharmacological activities of red yeast rice, its studies in humans, and a summary of recent case reports.
