The story of grain self â€sufficiency: China's food security and food for thought
This study, therefore, investigated spatial and temporal patterns of GSS at the county level in China from 1980s to the 2010s; then explored future GSS changes in the 2035s according to China's 2016 dietary nutrition guidelines, under the circumstances of maximum, average and minimum grain yield increase rate; and finally discussed the ability of a county to purchase grain to meet its demands. The results indicate that the number of counties with self-insufficiency for total grain and ration decreased, and the amount of counties with high-level self-sufficiency for total grain and ration increased. However, the change in t...

Model ?based evaluation of climate change impacts on rice grain quality in the main European rice district
We present here a modeling study to evaluate the future trends of rice quality in the main European rice district, placed in Northern Italy. A rice growth model was coupled with a library of models of rice milling and cooking suitability, using current farmer management and baseline/future climatic scenarios as input for the simulations. Four general circulation models (NOResm, MIROC-ESM, HadGEM2-ES, and GISS-ES) and two CO2 representative concentration pathways (2.6, 8.5) were used to generate 20-year future climatic data centered on 2030 and 2070. Spatially distributed simulations were run at 2 × 2 km spatial resolution...

A meta ?analysis of the effects of global warming on rice and wheat yields in a rice–wheat rotation system
The yield response to warming differed for rice and wheat in the rice-wheat rotation system. Overall, warming significantly increased wheat yield (by 4.8%) but significantly reduced rice yield (by 14.8%). For rice, yield responses to warming varied with the temperature increase, variety and nitrogen rate. For wheat, however, yield responses to warming varied with the warming regime, ambient temperature, temperature increases and CO2 concentrations. AbstractThe effects of global warming on crop production have received great attention in recent years. However, inconsistent results have been obtained with regard to major cro...

Public –private partnership model for intensive maize production in China: A synergistic strategy for food security and ecosystem economic budget
Small farms are the mainstay of maize production in China. Its productivity is relatively low despite large farm inputs and the associated environmental footprints. We studied public –private partnership (PPP) model for sustainable maize production to achieve co-benefits of food security and environmental sustainability. And the PPP model provides new insights into improving food security and ecosystem and economic budget. AbstractSmall farms are the mainstay of maize production in China. Its productivity is relatively low despite large farm inputs and the associated environmental footprints. Here, we studied public –priva...

Physiological and proteomic analyses reveal cAMP ?regulated key factors in maize root tolerance to heat stress
This study was designed to investigate cAMP roles in thermotolerance of maize root. Adenylyl cyclase (AC) cataly zes ATP to generate cAMP. For two identified maize AC genes,ZmRPP13-LK3 andZmPSiP, the predictive ABA response element was found in their promoter fragments. Both ABA and heat stress treatment increased the promoter activity ofZmRPP13-LK3 andZmPSiP. In the roots of maize ABA-deficient mutantvp5, the heat-caused increase of these two gene expression and cAMP content was obviously less than that in the roots of its wild-typeVp5. cAMP pretreatment decreased H2O2 and malondialdehyde content, but increased the activi...

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 past, however, the genetic gain in grain yi...

Arbuscular mycorrhizal fungi alleviate salinity stress in peanut: Evidence from pot ?grown and field experiments
In this study, peanut (Arachis hypogaea L.) seeds were inoculated with AMF to investigate its salinity stress alleviation effects using the pot-grown and 2-year field experiments. Seeds from two peanut cultivars (HY22 and HY25) were inoculated with AMFRhizophagus irregularis SA andFunneliformis mosseae BEG95 (1:1), and the physiological and transcriptional responses were compared between the AMF-inoculated and non-inoculated peanut plants. Under the salinity stress, compared with the control samples, the AMF-inoculated plants showed higher net photosynthetic rate, leaf relative water content (RWC), plant height, osmolyte a...

The impact of adopting stress ?tolerant maize on maize yield, maize income, and food security in Tanzania
The article would be of great interest to the readers of the journal because it emphasizes on issues of scalability of climate smart adaptation strategies. It builds on previous literature that looks at the heterogeneity in the impact of adopting improved technologies but extends and applies it to stress-tolerant maize in Tanzania. We can confirm that the material contained in the manuscript has not been published and is not being considered for publication elsewhere and does not infringe upon other copyright materials. AbstractProductivity growth emanating from scientific advances offered by biotechnology and other plant ...

Banana seed genetic resources for food security: Status, constraints, and future priorities
Over 430,000 seeds of 56 banana crop wild relative taxa are stored in 13 institutions in 10 countries. Despite this, most taxa are inadequately conserved in seed banks and they remain high priority for conservation. We identify major constraints to their conservation and make recommendations for future management, research and collection. AbstractStoring seed collections of crop wild relatives, wild plant taxa genetically related to crops, is an essential component in global food security. Seed banking protects genetic resources from degradation and extinction and provides material for use by breeders. Despite being among ...

T â€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...

Biodiesel production from camelina oil: Present status and future perspectives
Camelina sativa (L.) Crantz is an oilseed crop with favorable potentials for biodiesel production, such as the high plant yield, high oil content in the seed, high net energy ratio, and low oil production cost. This review paper deals with the present state and perspectives of biodiesel production from camelina oil. First, important issues of camelina seed pretreatment and biodiesel production are reviewed. Emphasis is given to different biodiesel technologies that have been used so far worldwide, the economic assessment of the camelina oil biodiesel (COB) production, the camelina-based biorefineries for the integrated bio...
