Genes that are expressed ubiquitously throughout all developmental stages are thought to be necessary for basic biological or cellular functions. Therefore, determining their biological roles is a great challenge. We identified 4034 of these genes in rice after studying the results of Agilent 44K and Affymetrix meta- anatomical expression profiles. Among 105 genes that were characterized by loss-of-function analysis, 79 were classified as members of gene families, the majority of which were predominantly expressed. Using T-DNA insertional mutants, we examined 43 genes and found that loss of expression of six genes caused developing seedor seedling-defective phenotypes. Of these, three are singletons without similar family members and defective phenotypes are expected from mutations. Phylogenomic analyses integrating genome-wide transcriptome data revealed the functional dominance of three ubiquitously expressed fam- ily genes. Among them, we investigated the function of OsO3g19890, which is involved in ATP generation within the mitochondria during endosperm development. We also created and evaluated functional net- works associated with this gene to understand the molecular mechanism. Our study provides a useful strategy for pheonome analysis of ubiquitously expressed genes in rice.

Convenience rice has become widely popular due to its easy availability for cooking. This study investigated the starch structure and composition of leachate and the microstructure of reheated convenience rice using novel processing technologies: super-heated steaming(SHS), auto-electric cooking(AEC), and pressurized-steam cooking(PSC). Additionally, the effect of two different target water contents(58% and 63%) was also evaluated. The PSC_63% sample had the highest total solids and amylopectin amount in the leachate. The amylopectin amount in the leachate differed significantly based on the targeted water content. Morphological characterization revealed that the swelling of starch and the coated layer on the surface of rice grains were most pronounced in the PSC_63% sample due to the pressure processing. The textural hardness of the AEC_58% sample was much higher than that of the other samples. The PSC_63% sample had the highest textural adhesiveness value, which can be attributed to the highest amylopectin amount in the leachate. Sensory characterization showed that the PSC_63% sample had the highest glossiness, whiteness, moistness, and overall acceptability. The principal component analysis score plots presented substantial differences in the leachate and textural and sensory characteristics of reheated convenience rice among the different processing technologies.
