T ‐FACE studies reveal that increased temperature exerts an effect opposite to that of elevated CO2 on nutrient concentration and bioavailability in rice and wheat grains
The combined elevated CO2 and temperature increased concentrations of some minerals but resulted in lower grain yields, thereby did not significantly change the yields of some minerals. The combined CO2 and temperature elevation increased phytic acid concentrations but limited the mineral bioavailability. Our results indicate that elevated temperature cancelled out the effect of elevated CO2, thereby, to a large extent, safeguarding the nutritional quality of rice and wheat under climate change. AbstractElevated CO2 concentration has been reported to decrease grain nutrient concentrations and thus worsen nutritional defici...

Higher relative humidity and more moderate temperatures increase the severity of rice false smut disease in the rice –crayfish coculture system
Rice false smut in rice –crayfish coculture (RC) was much more serious than the disease in rice monoculture (RM) among most rice varieties. Some varieties displayed resistance to rice false smut in RM, but were susceptible in RC, suggesting that the RC system is a better model than RM for evaluation of the resistance of rice varieties to false smut. In comparison with RM, RC showed higher relative humidity and more moderate temperatures from the rice booting stage to early filling stage. AbstractRice false smut, a devastating grain disease in rice, is a great challenge to global food security. Rice –crayfish co...

Microorganisms that are critical for the fermentation quality of paper mulberry silage
Bacterial community was analyzed by combination of NGS and SMRT sequencing. Wilting enriched the abundance ofLactobacillus rhamnosus.Lactobacillus rhamnosus was the critical species showing the most positively correlation with wilted silage quality, and have the potential to be developed as new silage inoculant. AbstractSilage quality remains an important issue in farming, as do limitations in the range of products suitable for animal fodder. We therefore explored the microorganisms that are critical for the fermentation quality of paper mulberry silage. Low (unwilted) and high (wilted) dry matter (DM) paper mulberry were ...

The role of polyamines in regulating amino acid biosynthesis in rice grains
This study was to clarify whether and how PAs regulate amino acid composition and content in milled rice. We grew three categories of rice cultivars differing in protein contents in the field and investigated the relationship of free-PAs concentrations in filling grains with the activities of key enzymes involved in amino acid biosynthesis and with the amino acid contents of milled rice. Cultivars with higher concentrations of free-Spermidine (Spd) and free-Spermine (Spm) exhibited higher amino acid contents than the others. The concentrations of free-Spd and free-Spm were significantly and positively correlated with the c...

The combination of different nitrogen fertilizer types could promote rice growth by alleviating the inhibition of straw decomposition
Ammonium bicarbonate combined with compound fertilizer in base fertilizer were used to investigate their effect on straw degradation and rice growth. AbstractStraw return plays an important role in the improvement of farmland ecological environments, increasing soil fertility, crop quality, and yield. However, in the early growth of rice (Oryza sativa L.), straw decomposition and rice growth may be inhibited by suboptimal carbon/nitrogen (C/N) ratios. We, therefore, explored methods that could alleviate the inhibition of straw decomposition using different combinations of ammonium bicarbonate and compound fertilizer. No fe...

Inter ‐annual climate variability constrains rice genetic improvement in China
Twenty-two of the seventy-eight GSR candidate cultivars achieved high grain yield and high NUE with reduced N fertilizer application. There was significant inter-annual variation in grain yield, which was significantly correlated withTmin. Grain yield positively correlated with NUEg (R2 = 0.46) and negatively correlated with protein content (R2 = 0.32), whereas NUEg negatively correlated with protein content (R2 = 0.49).Tmin negatively correlated with grain filling percentage (R2 = 0.95). AbstractYield potential has been significantly increased through hybrid rice breeding in the pas...

Spatial distribution and driving factors determining local food and feed self ‐sufficiency in the eastern regions of China
This study quantifies self-sufficiency in the eastern regions of China and examines correlations with agronomic (arable area, yield, fertilizer input, and machinery power) and socioeconomic (population density, gross domestic product [GDP]) variables at the local level, which are related to the interactions of the Sustainable Development Goals. We calculated food and feed balances, and checked correlations across and within regions grouped by population density levels between production, balance indices, and other agronomic and socioeconomic variables. The results showed that most regions can achieve self-sufficiency in ce...

Nitrogen/potassium interactions increase rice yield by improving canopy performance
Rice yield, N uptake, and NUE increased by combined application of N and K. The application N and K improved the canopy light and N distributions. Optimization of the canopy performance improved rice productivity and NUE. AbstractThe interactions between nitrogen (N) and potassium (K) are important determinants of rice yield, but the mechanisms involved remain poorly understood. For example, N/K interactions may influence light utilization and N distribution in the canopy. Field experiments were therefore performed to resolve this issue, using factorial combination of N and K. The interaction between N and K had a signific...

UV radiation increases mortality and decreases the antioxidant activity in a tephritid fly
The result suggests that the loss of antioxidant activity persistently reduces B. dorsalis performance under UV radiation. UV radiation is, therefore, a promising non-chemical measure for insect integrated pest management. AbstractUltraviolet (UV) radiation has been widely used to monitor insects and conduct surface sterilizations at 365  nm and 254 nm wavelengths, respectively. The global increase in the use of UV light has raised concerns about environmental impacts and effects on non-target organisms. We, therefore, examined the effects of three UV radiation wavelengths (365 nm, 308 nm and 254 n...

Tolerance to low phosphorus was enhanced by an alternate wetting and drying regime in rice
In this study, we characterized the responses of two rice varieties, ZD88 that has a weak tolerance to low soil P and YJ2 that has a strong tolerance to low soil P to two irrigation regimes under both optimal P (NP, 46.9  mg/kg Olsen-P) and low P (LP, 6.8 mg/kg Olsen-P). The first irrigation regime involved continuous flooding (CF), while the second involved alternate wetting and moderate soil drying (AWD). The study was conducted in plants grown in pot over two years. YJ2 exhibited stronger tolerance to LP than Z D88 under both irrigation regimes. Compared to CF, plants grown with AWD produced higher grain yield...
