Hakutsurunishiki is a sake rice cultivar bred using Yamadabo (seed parent) and Wataribune 2 (pollen parent), equivalent to a Yamadanishiki sibling. This study evaluated the structural characteristics of the Hakutsurunishiki rice grain that contribute to the brewing characteristics of daiginjo-shu, via a comparison with Yamadanishiki. Hakutsurunishiki brown rice was a little heavy and had a large white core. Observing a cross-section of white rice after soaking revealed that the rice grain structure of Hakutsurunishiki was different from that of Yamadanishiki. Hakutsurunishiki white rice showed fewer voids than Yamadanishiki, promoting a slower water absorption rate. Glucose distribution in rice koji obtained by mass spectrometry imaging showed that Hakutsurunishiki rice koji, like Yamadanishiki, is tsuki-haze type, suggesting that its grain structure is suitable for making rice koji for daiginjo-shu. With these observations, we were able to clarify the structural characteristics of Hakutsurunishiki rice grain.

Grain size is a crucial determinant of rice yield, yet the molecular mechanisms controlling this trait remain only partially understood. Here, we identified the JMJ720 locus as a key regulator of grain size through map-based cloning. The jmj720 mutant was found to exhibit significantly larger grains when compared to the wild type (WT).

Rice is a staple food for a large portion of the global population, while it is often associated with a high glycemic index. In this study, rice grains were for the first time dually treated with various concentrations of malic acid and different ultrasound durations to reduce starch digestibility. Results showed that a wide range of digestibility (up to ~30 % difference in the amount of starch digested after 120 min) reached after the treatments.

The enteric nervous system (ENS) is the intrinsic nervous system of the gut and controls essential functions, such as gut motility, intestinal barrier function, and water balance. The ENS displays a complex 3D architecture within the context of the gut and specific transcriptional states needed to control gut homeostasis. During development, the ENS develops from enteric neural progenitor cells (ENPs) that migrate into the gut and differentiate into functionally diverse neuron types.

Zhongzi purple rice is recognized as a nutritionally superior whole-grain variety, containing higher levels of protein, iron, dietary fiber, and vitamin B6 compared to conventional rice. While the nutritional profile of Zhongzi purple rice is well-established, the spatial distribution and structural specificity of its lipid components, especially germ-specific triacylglycerols (TAGs), remain poorly characterized. This study employs a multimodal mass spectrometric strategy to investigate the lipidomic uniqueness of the Zhongzi purple rice.

Abiotic stresses severely threaten global food security, underscoring the need for resilient crop varieties. We identified OsSPT38, a previously uncharacterized SUMO E3 ligase in rice, and discovered a rare gain-of-function mutation (Gly212Asp) that enhances both stress resilience and yield. This phenotype was validated in 18 additional independent mutants and by base editing in the elite indica cultivar Huanghuazhan.
