Nuclear genome substitutions between subspecies can lead to cytoplasmic male sterility (CMS) through incompatibility between nuclear and mitochondrial genomes. Boro-Taichung (BT)-type CMS rice was obtained by substituting the nuclear genome of Oryza sativa subsp. indica cultivar Chinsurah Boro II with that of Oryza sativa subsp. japonica cultivar Taichung 65. In BT-type CMS rice, the mitochondr...
Understanding the principles of abiotic and biotic stress responses, tolerance and adaptation remains important in plant physiology research to develop better varieties of crop plants. Better understanding of plant stress response mechanisms and application of knowledge derived from integrated experimental and bioinformatics approaches are gaining importance. Earlier, we showed that compiling a...
A small family of plant proteins, designated PSEUDO RESPONSE REGULATORS (PRRs), is crucial for a better understanding of the molecular link between circadian rhythm and photoperiodic control of flowering time in the dicotyledonous model plant Arabidopsis thaliana. Recently, we showed that the monocotyledonous model plant Oryza sativa also has homologous members of the OsPRR family (Oryza sativa...
BACKGROUND The domestication of Asian rice (Oryza sativa) was a complex process punctuated by episodes of introgressive hybridization among and between subpopulations. Deep genetic divergence between the two main varietal groups (Indica and Japonica) suggests domestication from at least two distinct wild populations. However, genetic uniformity surrounding key domestication genes across diverge...
Benzobicyclon is a new postflood-applied herbicide that was registered for use in U.S. rice (Oryza sativa L.) 2021 by Gowan Company. Therefore, research conducted to evaluate tolerance of commonly grown cultivars benzobicyclon. In 2018 and 2019, field experiments were near Stuttgart, AR the influence growth stage on benzobicyclon, pure line hybrid benzobicyclon following repeated acetolactate s...
Understanding how crop species spread and are introduced to new areas provides insights into the nature of species range expansions. The domesticated species Oryza sativa or Asian rice is one of the key domesticated crop species in the world. The island of Madagascar off the coast of East Africa was one of the last major Old World areas of introduction of rice after the domestication of this cr...
The S5 locus regulates spikelet fertility of indica/japonica hybrid rice (Oryza sativa). There are three alleles at the S5 locus, including an indica allele (S5i), a japonica allele (S5j), and a wide-compatibility allele (S5n). This study analyzed the molecular basis for S5-dependent reproductive isolation and compatibility of indica/japonica rice hybrids. Three S5 alleles were expressed at ext...
Using high quality sequence reads extracted from our whole genome shotgun repository, we assembled two chloroplast genome sequences from two rice (Oryza sativa) varieties, one from 93-11 (a typical indica variety) and the other from PA64S (an indica-like variety with maternal origin of japonica), which are both parental varieties of the super-hybrid rice, LYP9. Based on the patterns of high seq...
The fine structure of amylopectin affects rice quality; in particular, the chain length distribution (ACLD) milled differs between subspecies Oryza sativa L. However, correlation ACLD and quality trait factors, genetic basis phenotypic variation, are still unknown. Here, correlations with cooking eating rapid viscosity analysis (RVA) index were studied using chromosome segment substitution line...
The Indian subcontinent is the center of origin and diversity for rice (Oryza sativa L.). The O. sativa ssp. indica is a major food crop grown in India, which occupies the first and second position in area and production, respectively. Blast disease caused by Magnaporthe oryzae is a major constraint to rice production. Here, we report the analysis of genome architecture and sequence variation o...
