Open AccessDynamic Transcriptome Changes Driven by the Mutation of OsCOP1 Underlie Flavonoid Biosynthesis and Embryogenesis in the Develo** Rice Seed
CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1), an E3 ubiquitin ligase, functions as a central repressor of light signaling and regulates various light-mediated developmental and metabolic processes in plants. However...

Open AccessOsGATA16, a GATA Transcription Factor, Confers Cold Tolerance by Repressing OsWRKY45–1 at the Seedling Stage in Rice
Cold stress is the main abiotic stress in rice, which seriously affects the growth and yield of rice. Identification of cold tolerance genes is of great significance for rice to solve these problems. GATA-fami...

A new SNP in cyOsPPDK gene is associated with floury endosperm in Suweon 542
Pyruvate orthophosphate dikinase (PPDK) is a component of glycolysis to mediate endosperm energy charge by adjusting the ratio of ATP to ADP and AMP that proposed to balance the flow of carbon into starch, pro...

Quantitative shotgun proteomic analysis of cold-stressed mature rice anthers
Rice crops are vulnerable to low temperatures. During development, the reproductive stage is particularly sensitive to cold exposure, which causes abnormal pollen development and a high degree of male sterilit...

Open AccessGenome-wide resequencing of KRICE_CORE reveals their potential for future breeding, as well as functional and evolutionary studies in the post-genomic era
Rice germplasm collections continue to grow in number and size around the world. Since maintaining and screening such massive resources remains challenging, it is important to establish practical methods to ma...

Article
Analysis of quantitative trait loci associated with seed germination and coleoptile length under low temperature condition
Low temperature stress will lower the germination rate of rice, reduce its growth, and delay the emergence of rice seedlings from paddy water surface, resulting in decreased seedling and mortality. Here, we co...

Open AccessA quantitative shotgun proteomics analysis of germinated rice embryos and coleoptiles under low-temperature conditions
At low temperatures, rice grains have a reduced germination rate and grow more slowly, which delays the emergence of rice seedlings from the paddy water surface and significantly increases seedling mortality. ...

Chapter
Marker-Assisted Breeding
Marker-assisted breeding (MAB) is based on the theories and technology of molecular biology to improve the efficiency of conventional breeding. Molecular markers can be applied to marker-assisted selection (MA...

Association analysis of seed longevity in rice under conventional and high-temperature germination conditions
Seed longevity varies considerably in cultivated rice, but the underlying mechanism of longevity is not well understood. To measure seed longevity, we performed an aging treatment at 45 °C on seeds maintained ...
