Shifts of arbuscular mycorrhizal fungal functioning along a simulated nitrogen deposition gradient
In this study, the mycorrhizal response affected by environmental N enrichment was addressed by conducting a glasshouse experiment, and four fertilization treatments (N1, N2, N3, and N4, 0, 15, 30, and 60 kg N hm−1 a−1, respectively) were used to simulate N deposition differences over the mycorrhizal response. The changes in mycorrhizal colonization and plant variables during different AMF and N fertilizer applications were investigated. When the gradient's nitrogen levels increased, the mycorrhizal growth response and mycorrhizal nitrogen response showed a pattern of first dropping and then increasing. N-indu...

Study on the impact of low ‐temperature stress on winter wheat based on multi‐model coupling
AbstractCrop growth models, such as the WOrld FOod STudies (WOFOST) model, mimic the mechanistic processes involved in crop development, growth, and yield production. The accuracy of simulation is decreased in unfavorable low-temperature settings because these models do not accurately represent crop response processes in low-temperature stress. Enhancing the WOFOST crop growth model's accuracy in simulating crops' responses to cold temperatures is the aim of this work. Given its vulnerability to low temperatures, the inquiry uses winter wheat in Henan Province as a focal point. It integrates the WHEATGROW wheat phenology m...

Agronomic and physiological characteristics of high yield and nitrogen use efficient varieties of rice: Comparison between two near ‐isogenic lines
In conclusion, NIL-dep1 had high grain yield and NUE by improved agronomic and physiological traits and increasing carbon and nitrogen translocation during grain filling. These traits mentioned above could be used to select and breed high grain yield with high NUE rice varieties. (Source: Food and Energy Security)

Reorienting research investments toward under ‐researched crops for sustainable food systems
AbstractThe dominance of a few staple crops (maize, rice, and wheat) in most agricultural systems hampers the application of interventions to improve food security and nutrition. Research and development attention has focused on improving the production and utilization of these crops, leaving other crops under-researched and underutilized. Subsequently, there have been high malnutrition rates due to poor diet diversity, yet there are “opportunity crops” that remain under researched. The opportunity crops can unlock solutions to food insecurity, malnutrition, a lack of biodiversity, and indeed poor climate adaptation. T...

Sustainable protein production through genetic engineering of cyanobacteria and use of atmospheric N2 gas
AbstractThis review explores the potential of genetically engineering cyanobacteria with the aim of synthesizing high-value protein directly from atmospheric nitrogen. The article examines numerous techniques that may enhance protein synthesis in cyanobacteria, and discusses advantages, barriers, and opportunities for this strategy going forward. Genetic manipulation of cyanobacteria shows promise in sustainably raising protein production via reduced greenhouse gas emissions and lower dependence on synthetic fertilizers, but also potentially fewer environmental implications traditionally caused by conventional protein prod...

The role of husk traits in maize susceptibility to Fusarium verticillioides: A multi ‐location study in northern Italy
AbstractFusarium disease and the consequent mycotoxin accumulation pose significant problem in maize cultivation, with fumonisins produced byFusarium verticillioides posing a global health concern. To address this issue, a range of preventive measures (e.g. crop management techniques) can be implemented to minimize fungal infections. A promising strategy to counteract this issue involves the selection of genotypes with greater resistance to fungal pathogens. This approach has the potential to reduce the reliance on chemical inputs for controlling fungus growth or indirect infection vectors. Leveraging genetic approaches ca...

Effect of agricultural intensification on the genetic diversity of Helicoverpa armigera
In this study, we investigated the effects of the composition and configuration of the landscape on the genetic diversity of the agricultural pestH. armigera based on cytochrome oxidase subunit I (COI) analyses. In total, 10 haplotypes were found in 2016 and 15 haplotypes in 2021 based on COI genes. The haplotype diversity and nucleotide diversity were the highest in the Anqiu (AQ) region during 2016 and in the Bincheng (BC) region during 2021. Haplotype 2 and haplotype 3 (Hap2 and Hap3) were the dominant haplotypes in theH. armigera population. Agricultural intensification had no effect on the genetic diversity ofH....

Building forests for the future
AbstractMany governments have set ambitious targets for tree planting and increased woodland cover as a key part of actions to reach net-zero carbon emissions by 2050. However, many uncertainties remain concerning how and where to expand tree cover, what species to plant, and how best to manage new plantations. Much contemporary forestry has been based on even-aged monocultures, largely because of perceived advantages for timber production. However, in order to play a key role in climate change mitigation future forests will have to achieve timber production (and wider ecosystem service provision) alongside resilience to b...

Impact of urban productive safety net programme on poverty reduction and food security: Evidence from major cities of Eastern Ethiopia (Dire Dawa, Harar and Jigjiga)
This study employed both propensity score matching (PSM) and endogenous switching regression (ESR) models to assess the impact of the UPSNP. The result shows that the probability of a household's participation decision is determined by the age of the household head, number of children, savings, house ownership, employment status of the household head, and shock. Furthermore, we found a consistently positive impact across models, indicating that participation in UPSNP reduces poverty and increases food security of households.

The regulatory landscape of genetically engineered crops in Pakistan
AbstractGenome editing technology has become part and parcel of biotechnological approach to understand the genetic basis of different biological processes in an organism and for its application in different fields. The basic need of world food production demands a highly variable population of plants with maximum diversity of agronomic traits of interest. Genome editing is unique in the sense that it provides a direct approach to generate targeted variability. The worldwide availability of genome-edited crop varieties in the global market is approaching, whereas the decision to deal with genome-edited (GE) crops different...
