The OsNAC23-Tre6P-SnRK1a feed-forward loop regulates sugar homeostasis and grain yield in rice
Tre6P phosphatase trehalose OsNAC23
2023/3/9
Tre6P (trehalose-6-phosphate) mediates sensing of carbon availability to maintain sugar homeostasis in plants, which underpins crop yield and resilience. However, how Tre6P responds to fluctuations in...
OsYUC11-mediated auxin biosynthesis essential for grain filling of rice
OsYUC11 auxin grain filling rice
2023/7/20
Auxin is a phytohormone essential for plant development. However, our understanding of auxin-regulated endosperm development remains limited. Here, we described rice YUCCA (YUC) flavin-containing mono...
Effects of Soil Type,Vertical Root Distribution and Precipitation on Grain Yield of Winter Wheat
Grain yield Precipitation Root system Soil type Solar radiation Sunshine duration Temperature Winter wheat
2010/3/4
In Abashiri in eastern Hokkaido, Japan, grain yields of winter wheat (Triticum aestivum L. cv. Hokushin) in the western area, with umbric andosol or dystric cambisol soil types, are lower and unstable...
Water Status and Grain Production of Several Japonica Rices under Grain-filling Stage Drought
Drought Dryland rice Grain-tilling stage Leaf water potential
2009/8/6
This study was designed to compare leaf water potential (LWP) and grain yield responses to drought imposed during the grain-filling stage in several Japonica dryland (upland) and wetland (paddy) rice...
Growth and Grain Yield of Wheat in Relation to Differences in Soil Groups:II. The emergence and survival of tillers and their contribution to yield
Adaptability to low phosphoric-acid concentration Andosol Gary Lowland Soil Number of spikes
2009/8/5
The emergence and survival of tillers and their contribution to yield of three varieties, Asakazekomugi, Norin 61 and Norin 64, were examined in four different soils to find the limiting factors to gr...
Partitioning of 15N Applied at Reproductive Stages among Grains and in Grain Tissues of Rice Plants
Competition Grain Nitrogen Partitioning Position on panicle Rice Ripening
2009/8/4
Hydroponically-grown rice (Oryza sativa L.) plants were pulse-labelled with 15N-ammonium sulphate at various stages of reproductive growth, and partitioning of 15N among grains or grain tissues were e...
Grain Filling in Rice Subjected to Drought at Three Stages
Drought Grain filling Imperfect rice kernel Rice Water stress Winnowed paddy
2009/8/4
The effects of water stress on the grain growth of rice appear to depend on the stages of plant development. The plants which were subjected to water stress during the grain-filling period produced mo...
Cultivar Differences in Leaf Photosynthesis and Grain Yield of Wheat under Soil Water Deficit Conditions
Cultivar difference Drought Grain yield Photosynthesis Soil water deficit
2009/7/30
Cultivar differences in leaf photosynthesis (LPS) and grain yield of wheat [Triticum aestivum L.] were examined under irrigated and non irrigated conditions in Cerrados, a semi-arid region in Brazil. ...
Association of Grain Shedding Habit with Polyploidy in Tartary Buckwheat (Fagopyrum tataricum) Strains
Buckwheat Flow cytometry Grain shedding habit Grain size Polyploidy Tartary buckwheat
2009/7/28
Sixty tartary buckwheat (Fagopyrum tataricum) strains were investigated for grain shedding habit, plant height, grain yield, dry weight of plant, weight of grain, days to flowering after sowing and DN...
Effect of CO2 Enrichment on the Translocation and Partitioning of Carbon at the Early Grain-filling Stage in Rice (Oryza sativa L.)
13C CO2 enrichment Grain-filling Partitioning Rice Sink Translocation
2009/7/24
Rice plants (Oryza sativa L.) were grown under normal (350 μL L-1 CO2) and CO2-enriched (660 μL L-1 CO2) conditions, and 13CO2 was supplied to the rice plants after heading to examine the translocatio...
Activities of Enzymes for Sucrose-Starch Conversion in Developing Endosperm of Rice and Their Association with Grain Filling in Extra-Heavy Panicle Types
ADPglucose pyrophosphorylase Developing endosperm Extra-heavy panicle type Grain filling Inferior spikelet Rice Sink activity Sucrose synthase
2009/7/23
Rice cultivars with numerous spikelets per panicle (extra-heavy panicle types) frequently fail to exhibit their high yield potential due to low grain filling. Existing genetic variation in grain filli...
Spatial Distribution of Leaf Area Index and Leaf N Content in Relation to Grain Yield and Nitrogen Uptake in Rice
Grain yield Leaf area index Leaf N content N uptake Spatial distribution
2009/7/23
Exploring approaches to optimizing spatial distributions of leaf area index (LAI) and leaf nitrogen content (LNC) should be useful for increasing grain yield in rice (Oryza sativa). The primary object...
