Impacts of the COVID ‐19 pandemic on vegetable production systems and livelihoods: Smallholder farmer experiences in Burkina Faso
Impacts of COVID-19 experienced by smallholder vegetable farmers in Burkina Faso were collected through surveys. They expressed reduction in access to inputs, reduced yields, loss of income, reduced access to local and urban markets, reduced access to transportation, and increased post-harvest loss. These impacted lives, livelihoods, and social well-being of families, especially women and youth. AbstractAt the onset of COVID-19, researchers quickly recognized the need for research on the consequences of the pandemic for agricultural and food systems, both in terms of immediate impacts on access to inputs and labor, disrupt...

Prospects to improve the nutritional quality of crops
This manuscript focus on different examples on how to improve the protein content and composition of crops, the content of micronutrients and other healthy compounds as well as how to remove unhealthy compounds. AbstractA growing world population as well as the need to enhance sustainability and health create challenges for crop breeding. To address these challenges, not only quantitative but also qualitative improvements are needed, especially regarding the macro- and micronutrient composition and content. In this review, we describe different examples of how the nutritional quality of crops and the bioavailability of ind...

Rice seedlings grown under high ammonia do not show enhanced defence responses
We investigated the molecular/genetic regulation of ammonia tolerance in rice using a multidisciplinary approach consisting of high-resolution LC-MS/MS analysis and bioinformatics, together with plant molecular physiology and biochemistry. Proteomic analysis revealed changes in the levels of 266 proteins, which function in translation and protein metabolism, amino acid and carbon metabolism/transport, antioxidant and redox metabolism. The abundance of the transcripts encoding these proteins was increased under high ammonium. Data are presented showing that ammonia-induced changes in metabolism are linked to a strong antiox...

Increasing pit ?planting density of rice varieties with different panicle types to improves sink characteristics and rice yield under alternate wetting and drying irrigation
Increasing rice planting density can compensate for the negative impact of AWD on yield by increasing spikelets density, which may be a way to eliminate the risk of AWD reducing yield. AbstractThe Chinese government regards ensuring food security and developing water-saving agriculture as an important national strategy and that carrying out relevant research has important practical significance and production application value. A two-year field experiment was conducted to explore the compensation potential in rice yield by using rice varieties with different panicle size under two water management regimes (conventional wat...

Potential applications of the CRISPR/Cas technology for genetic improvement of yam (Dioscorea spp.)
Yam is an economically important crop grown in the tropical and subtropical world, producing tuberous root as a staple food, and an income source for millions of farmers. Yam production is constrained by disease and pest infestations and a range of abiotic factors. Advanced genetic engineering tools such as CRISPR/Cas-based genome editing have the potential for developing improved varieties of yam with diseases and pests resistance. AbstractYam (Dioscorea spp.) is an economically important crop grown in the tropical and subtropical regions, producing tuberous roots that serve as a staple food, an income source, and an exce...

Drought imprints on crops can reduce yield loss: Nature's insights for food security
The United States Midwest is moving towards a climate pattern with wetter springs and drier mid- to late-summers. This change in precipitation pattern, however, suggests that opportunities for crop priming may lessen in the future. Here, we quantify drought priming effects on maize and soybean and analyze what plant traits may associate with the observed priming effects in the field scale. AbstractThe Midwestern “Corn-Belt” in the United States is the most productive agricultural region on the planet despite being predominantly rainfed. In this region, global climate change is driving precipitation patterns toward wett...

Identification of genomic loci regulating grain iron content in aus rice under two irrigation management systems
In this study, 225 –269 accessions of the Bengal and Assam Aus Panel (BAAP) were investigated for their accumulation of grain Fe in two consecutive years in a field experiment under alternative wetting and drying (AWD) and continuous flooded (CF) irrigation. AWD reduced straw Fe by 40% and grain Fe by 5.5–13%. Gen otype differences accounted for 35% of the variation in grain Fe, while genotype by irrigation interaction accounted for 12% of the variation in straw and grain Fe in year 1, with no significant interactions detected in year 2. Twelve rice accessions were identified as having high grain Fe for both years rega...

Dryland maize yield potentials and constraints: A case study in western Kansas
This case study used crop modeling to analyze dryland maize yield potential, farmers ’ yield potential, and actual farm yields from 1990 to 2015 in three counties in western Kansas (i.e., Thomas, Greeley, and Finney in the U.S. Great Plains region). The calibrated APSIM-Maize model along with actual yields was used to estimate yield gaps attributed to the agronomic factors. AbstractWater-limited environments account for half of the earth's land surface, and dryland agriculture acreage is projected to expand due to climate changes. Examining typical dryland yield potentials and yield improvement measures is crucial for de...

Measuring total ‐factor energy environment efficiency, energy‐saving and carbon emission‐reduction potential in China's food industryAQ1: Based on a meta‐frontier slacks‐based measure model
This paper measures the total-factor energy environment efficiency of China's food industry based on a method that combines the slacks-based measure model with meta-frontier technology. This paper calculates the energy saving and carbon dioxide emission reduction potential of China's food industry. AbstractChina's food industry is a large energy consumer and carbon emitter due to its huge scale, so it cannot be ignored if China wants to achieve the goals of energy conservation, emission reduction, and clean production. It is necessary to conduct an in-depth analysis of the energy environment efficiency of the industry. Thi...

Household food insecurity after the early monsoon flash flood of 2017 among wetland (Haor) communities of northeastern Bangladesh: a cross ‐sectional study
The present study assessed the post-flood household food insecurity and the factors associated with it in the aftermath of the 2017 flash flood in northeastern wetland (Haor) area of Bangladesh. A survey covering randomly selected 1845 flood affected households found that a staggering 62% of the surveyed households were food insecure following the flash flood. Being ultra-poor, loss of livestock in flood, household head's occ upation being natural resource-based, and household reliance on market purchase of food were identified as significant risk factors of post-flood household food insecurity. AbstractThe livelihoods ...

TaERF73 is associated with root depth, thousand ‐grain weight and plant height in wheat over a range of environmental conditions
In this study, a novel ERF geneTaERF73 was cloned from wheat. qRT-PCR analysis showed thatTaERF73 is predominantly expressed in roots. It responds to treatments of auxin, MeJA, ABA, low temperature and drought stresses. Ectopic expression ofTaERF73 in rice caused short root length, indicating thatTaERF73 is a negative regulator of root growth. Four SNPs were detected inTaERF73-4B coding region through sequence polymorphism analysis. A dCAPS (derived cleaved amplified polymorphic sequence) molecular marker was developed based on the SNP at 119 bp (G/C) ofTaERF73-4B. Association analysis between genotypes and agronomic tra...
