TL;DR: Soil property and organic matter content increase the availability of Fe and Zn in rhizosphere, which in turn enhances the uptake, translocation and redistribution of Fe/Zn into rice grains, indicating that genetic makeup of a plant determines its response to varied soil conditions and other external factors.

TL;DR: The advance in study of riceWRKY gene family is reviewed and a unified nomenclature for rice WRKY factors to eliminate confusion is proposed.

TL;DR: Taichung, a semi-dwarf, low amylose content and early maturing rice variety, showed a significantly higher germination rate at the three temperature treatments and its coleoptile length was significantly higher than other germplasms.

TL;DR: The genetic distances among 18 cytoplasmic male sterile lines and 11 restorer lines were analyzed with molecular markers derived from yield-related functional genes and showed that the genetic distance was significant correlated with yield heterosis, but not significantly correlated with heterosis for other traits.

TL;DR: Model-based cluster analysis revealed that the japonica-like group maintained very pure ancestry while the indica group shared mixed ancestry, especially for group III, which had seven admixtures sharing from 19.5% to 30.0% of ancestry with group IV (based on SSR markers).

TL;DR: It is suggested that water stress induced spikelet sterility by damaging antioxidant enzyme activities, reducing carbohydrate content in spikelets and decreasing pistil water potential at the flowering stage in rice.

TL;DR: In this article, the relationship between lodging resistance and chemical component contents in culms and leaf sheaths of rice, the physical strength and maximum bearing capacity of culm, and the contents and amounts of potassium (K), silicon (Si), and soluble sugars in both leaves and culms were investigated using four japonica rice varieties.

TL;DR: The origin, genetic modes, isolation and characterization of spotted-leaf genes responsible for their phenotypes, and their resistance responses to main rice diseases are reviewed.

TL;DR: To understand the male sterility mechanism of photoperiod/thermo-sensitive genic male sterile [P(T)GMS] lines in rice, the research progress on genetics of Photoperiod and/or temperature sensitive genicmale sterility in rice was reviewed and a new idea was proposed to explain the sterility mechanisms.

TL;DR: The feasibility of partially replacing wheat flour with malted rice flour in bread making was evaluated in several formulations, aiming to find a formulation for the production of malted Rice-wheat bread with better nutritional quality and consumer acceptance as discussed by the authors.

TL;DR: The presence of characteristic bands in selected varieties is a useful parameter for identification of rice germplasm.

TL;DR: The genotypic correlation coefficient was higher than the phenotyping correlation coefficient, indicating strong inherent associations among the characteristics studied, and implies that these characteristics are mainly under additive gene effects and could be relied upon further selection based on phenotypic performance.

TL;DR: The frequency distributions of the germination traits under salt stress in the RIL population showed continuous segregation, suggesting that they were quantitative traits controlled by several genes.

TL;DR: The transgenic embryonic calli selected by the crude toxin of rice blast fungus showed that the callus induction rate of immature embryo from transgenic rice plants decreased as the concentration of crude toxin in the culture medium increased, indicating that the rice blast resistance of transgenic Rice lines is much higher than that of the receptor control.

TL;DR: The basic content and studies of HGT, and its application in rice and maize were summarized, and necessity and urgency in hybrid rice breeding by using HGT were proposed.

TL;DR: A doubled haploid population consisted of 120 lines, derived from a cross between an indica variety and a japonica variety, Chunjiang 06, was used to identify QTLs controlling rice cold tolerance at the plumule and 3-leaf-seedling stages by using the QTLNetwork software.

TL;DR: The four exogenous phenolic acids induced the enhancement of the allelopathic potential of wild rice S37 in target weeds though the weed-suppressive activities were low, and the inducible effects were dependent on the specific phenolic acid, concentration and treatment time.

TL;DR: Results suggest that OsAP2LP might be involved in stress responses, and probably plays roles as a transcription regulator when plants response to cold, salt and drought stresses through ABA and gibberellin pathways.

TL;DR: RP, RT-PCR and Southern-blotting assay showed that the gene of interest had been integrated into rice genome and stably inherited, and some lines with high resistance to rice leaf blast and neck blast were obtained.

TL;DR: Significant effects of temperature and rice variety on contents of soluble sugar and oxalic acid in rice plants are indicated and two-way ANOVA indicated significant effects of weather and temperature on resistance characteristics of rice varieties.

TL;DR: The study revealed a high genetic diversity among non-basmati scented rice accessions and the bands present specifically among three accessions of non- BasmatiScented rice were also identified.

TL;DR: It is suggested that the activities of key enzymes for starch synthesis and glutamine synthetase could be changed in oriented breeding for amylose and protein contents in grains.

TL;DR: The development and achievements of super rice breeding in aspects of the breeding methodology and breeding practices are reviewed, the successful experience of super Rice breeding in China is summarized, and the developmental strategies ofsuper rice for the future are proposed.

TL;DR: Diversity of 60 conventional japonica rice accessions with good eating quality at home and abroad was analyzed using SSR molecular markers, agronomic traits and taste characteristics, which indicates that taste characteristics of some varieties were mainly genetically determined.

TL;DR: A simple method for preparation of rice genomic DNA was developed, which is simple, rapid, low cost, and reliable for PCR analysis, especially suitable for genotyping of large number of samples.

TL;DR: To detect loci controlling rolled leaf of japonica restorer lines, SSR marker genotypes and phenotypes of flag leaf rolling index were investigated in Xiushui, and 12 markers showed highly significant correlation with LRI in both environments based on single marker regression analysis.

TL;DR: Estimation of the tolerance to 150 mmol/L NaCl, 20% PEG6000 and low temperature treatments, and relevant physiological indices suggest that the OsCBL8 gene is involved in the response of rice to abiotic stresses.

TL;DR: A two-line hybrid rice combination, Liangyoupeijiu, was used to estimate several factors of plant type and environmental models for these factors at the heading stage were established using the data of eight ecological experimental sites in 2006 and 2007.

TL;DR: A double PCR detection indicated that combined use of the two markers could easily distinguish the genotypes of Lgc1 from different rice varieties, and the molecular marker could be widely used to identify different varieties with LGC1 gene and applied in marker-assisted selection of low glutelin-content rice.

TL;DR: Using canonical correlation analysis and canonical redundancy analysis, the relationship between plant type traits and rice grain quality traits was studied with 100 crosses derived from 10 sterile lines × 10 restorer lines and indicated that japonica hybrid rice in Northern China with good quality was characterized by broad flag leaf and 2nd leaf from the top.
