高彩霞 农业 植物生物技术 作物分子设计育种
2020/9/29
现代农业面临着诸多困境与挑战。现有的农作物栽培品种亟需改良与优化，以应对日益恶化的环境问题以及不断增长的世界人口。相比于传统育种，来自于原核生物的CRISPR-Cas系统可以准确、高效、可编程地对农作物基因组进行编辑，从而为未来的农业发展提供了新的机遇。中国科学院遗传与发育生物学研究所高彩霞研究组一直致力于植物基因组编辑技术创新及作物分子设计育种应用的研究。2020年9月24日，国际重要综述期刊N...
Varietal Differences in the Growth and Dry-Matter Production during Vegetative Growth in Rice under Upland Cultivation Conditions with Water Stress : A comparison of Japonica, Indica and Japonica-Indica hybrid cultivars(Crop Physiology and Cell Biology)
Drought resistance Dry matter production Growth Japonica-Indica hybrid Oryza sativa L.
2009/7/15
Since rice is highly susceptible crops to water stress, it is important to improve drought resistance to increase and stabilize the rice yield under upland cultivation conditions. This study was condu...
Effects of Exogenous Injection of Sucrose Solution to Plant on the Carbon Distribution to Tuberous Root and Tuberous Root Production in Sweet Potato, Ipomoea batatas Lam(Crop Physiology and Cell Biology)
ADP-glucose pyrophosphorylase Carbon distribution Sink Source Sucrose Sweet potato
2009/7/15
The sink and source balance in a sweet potato plant was artificially changed by exogenously injecting a 6% sucrose solution into the cut end of the stem, and its effect on the photosynthate transport ...
Some Limiting Factors and Improvement for the Overwintering Ability of Spring Wheat Sown before Continuous Snow Cover(Crop Physiology and Cell Biology)
Germination Overwintering ability Seed Seed nutrient Snow mold Sowing before continuous snow cover
2009/7/15
It has been known that spring wheat sown immediately before continuous snow cover has higher quality and yield than that sown in spring in the heavy snowfall areas of Hokkaido. To increase the stabili...
Changes in Leaf Rolling Rate of the Rice and Effect of Evaporative Condition(Crop Physiology and Cell Biology)
Air temperature Developmental stage Diurnal change Leaf rolling Leaf water potential Photosynthetically active radiation
2009/7/15
The diurnal change and change with the daily change of Leaf-rolling rate (LRR), and the effect of LRR on leaf water potential (LWP) under a high-temperature/low-humidity condition were examined. At no...
A Grant of Drought Avoidance and Efficient Water Use because of Dwarfing Genes Utilization(Crop Physiology and Cell Biology)
Consumptive use Drought avoidance Dry matter increase Dwarfing genes Transpiration efficiency
2009/7/15
Tall and dwarf isogenic lines of sorghum (Plainsman tall type and Plainsman short type), soybean (Hyuga and Hyuga dwarf line), and rice (Ginbozu and Tangin) were grown by using 15 L containers to comp...
Effects of Gibberellin and Cytokinin on the Resistance to Cool Weather at the Young Microspore Stage in Rice Plants (egular Paper>Crop Physiology and Cell Biology)
Cool-weather resistance Cytokinin Fertility Gibberellin Nitrogen Pollen Rice Young microspore stage
2009/7/14
The effects of gibberellin, cytokinin and an inhibitor of gibberellin biosynthesis on spikelet fertility and the number of pollen grains were examined in rice plants which were cooled at the young mic...
Diurnal and Phenological Changes of Bleeding Rate in Lowland Rice Plants(Crop Physiology and Cell Biology)
Bleeding rate Developmental stage Diurnal change Oryza saliva L Phytomer
2009/7/10
The bleeding rate of rice plants grown in the farmer's paddy field was examined for use as an index of root activity. The bleeding rate started to decrease immediately after removing the shoot of rice...
Effects of Plant Growth Regulators on Number of Spikelets per Panicle in Rice (Oryza sativa L.) under Saline Flooding Conditions(Crop Physiology and Cell Biology)
Degeneration of spikelet Gibberellin Irradiance Malformation of palea and lemma Rice Salinity stress
2009/7/10
The changes in number of spikelets per panicle (SN) under saline conditions as affected by the application of plant growth regulators were determined. A lowland rice cultivar IR28 whose SN is reduced...
Effect of High Temperature on Ripening in Rice Plants:Comparison of the effects of high night temperatures and high day temperatures(Crop Physiology and Cell Biology)
Grain dimension Grain quality Grain weight Growth cabinet High day temperature
2009/7/10
The effects of high-temperature stress on rice ripening is well documented. However, it is unclear which is more effective on rice ripening, high night temperature (HNT) or high day temperature (HDT) ...
