Tolerance of plant virus disease: Its genetic, physiological, and epidemiological significance
Plant viruses lead to biotic stress in plants, affecting growth, reproductive fitness and yield. Tolerance of viruses and virus disease may provide a host defence mechanism against deleterious effects, but further physiological and epidemiological studies are required to determine the circumstances in which it can be effectively used for crop improveme nt. A broader view of stress tolerance incorporating both biotic and abiotic stressors is required as in some cases plant viruses have been shown to mitigate environmental stress. AbstractThe development and use of tolerance have been proposed as an alternative or complem...

Estimation of grain yield in wheat using source –sink datasets derived from RGB and thermal infrared imaging
This study demonstrates that the multivariate eigenvalues of both source and sink organs have the potential to predict wheat yield, and that the combination of machine learning models and variable selection methods can significantly affect the accuracy of yield prediction models and achieve effective monitoring of crop growth at late reproductive stages. AbstractTimely and efficient monitoring of crop aboveground biomass (AGB) and grain yield (GY) forecasting before harvesting are critical for improving crop yields and ensuring food security in precision agriculture. The purpose of this study is to explore the potential of...

Orphan crops: A genetic treasure trove for hunting stress tolerance genes
Deciphering the complexities of abiotic stress tolerance is a huge task and requires good model crops for investigation. Advancements in genomic technologies have made it possible to sequence and analyze a large number of orphan crops, which are known for their abiotic stress tolerance potential. AbstractOrphan crops, also known as minor crops, smart foods, and superfoods, have attracted great attention recently because of their unique ability to grow in resource-poor marginal lands, and under harsh environmental conditions without any intensive agricultural care. These crops possess inherent tolerance against different ab...

Crop improvements for future ‐proofing European food systems: A focus‐group‐driven analysis of agricultural production stakeholder priorities and viewpoints
This study presents results from a series of online focus groups conducted with agricultural production related stakeholders (i.e. farmers and farmer representatives, policymakers and NGOs) regarding the potential for crop improvement to future-proof European food systems. Stakeholders shared concern around climate change and environmental impacts (particularly drought and heat stress), and general agreement about the need to develop resilient crops which combine multiple positive attributes, while reducing trade-offs and negative externalities. Stakeholders also prioritized plant breeding solutions for areas where they fe...

Does green vertical farming offer a sustainable alternative to conventional methods of production?: A case study from Scotland
Life cycle analysis using lettuce as an example crop indicate that electricity consumption by VF account for 91% of the carbon footprint. Under the 2020 Scottish electricity mix, vertical farming was seen to be comparable with UK open-field agriculture in environmental impacts. This lowers further under a 100% renewable electricity generation scenario, offer a low carbon production method and a potential alternative for sustainable future produce. AbstractClimate change is an existential global reality that is placing considerable stress on agriculture sectors. With the recognition of the impacts of climate change on food ...

To sell or store? Assessing smallholder farmers' willingness to pay for potato cold storage in Kenya
We use a double-bounded format of contingent valuation to assess WTP for potato cold storage among smallholder farmers in Kenya. The results show that seasonal price gaps were higher than the estimated WTP suggesting that potato storage could be economically viable. AbstractStorage of food commodities for some time after harvest can play an important role in alleviating the downside of price fluctuations in developing countries. While storage can offer smallholder farmers substantial inter-temporal arbitrage opportunities, existing evidence shows that many farmers in developing countries store little of their harvest. Usin...

Rice and food security: Climate change implications and the future prospects for nutritional security
Rice is a staple crop in many parts of the world and in this review, we highlighted the prospects of rice for future climatic conditions. In this review, we describe how rice could be a better option for future food and nutritional sustainability. This review describes the advantages and prospects of rice, to address why it is the best for the future situation and future questions and actions that are needed to develop a sustainable future food supply in light of global climate change. AbstractEnvironmental stresses including salinity, drought, cold, warmer temperatures, alterations in precipitation patterns, fluctuations ...

Contrasting seasonal dynamics of dormancy, respiratory metabolism and cell cycle state in grapevine buds of a subtropical and Mediterranean climate
This study investigated the growth and metabolic physiology of the perennating bud of commercially grown cv. Flame Seedless table grapes from Mediterranean and subtropical climate in Western Australia, from summer until late winter. Climate data were obtained, showing differences in minimum (night) temperature between the two climates, reflected by differences in calculated chilling units. Bud dormancy increased during autumn of both climates;however, the onset and depth of dormancy of buds from the subtropical region were attenuated relative to the Mediterranean condition. Stark contrasts were also observed in metabolism....

Quantitative trait loci, candidate genes, and breeding lines to improve salt tolerance at the flowering and seedling stages in rice
In this study, genetics of salinity tolerance at the flowering stage was compared with that of seedling stage. The candidate genes and salt-tolerant breeding lines at both vulnerable stages were identified to accelerate development of salt-tolerant rice varieties. AbstractSalinity is a major environmental constraint that limits growth and productivity of rice all over the world. Although rice plants are vulnerable to salt stress at both seedling and flowering stages, genetic dissection of salt tolerance at the flowering stage is challenging due to non-uniformity of stress application at the appropriate growth stage. The pr...

Impact assessment of Striga resistant maize varieties and fertilizer use in Ghana: A panel analysis
This study analyzes the impact of a component of climate-smart agriculture (CSA) technology —Striga-resistant maize (SRM) varieties and mineral fertilizer—on maize yield and food security using two rounds of panel data in Ghana. The study employs a multinomial endogenous switching regression model and finds that joint adoption of SRM varieties and mineral fertilizer increased maize yie ld by 872 kg/ha, food consumption scores by 17, and consumption per adult equivalent unit by 38 kg/ha. The positive impact of maize yield is high among adopters of multiple CSA technologies. The result is robust to an alternative end...

Rhizosphere soil nitrification ability controls nitrogen ‐use efficiency in rice growth period
The impacts of the rhizosphere soil nitrification rate on NUE and denitrification losses at different rice growth stages in two paddy soils were investigated. Rhizosphere nitrification played a dominant role in increasing denitrification and decreasing NUE. Rhizosphere nitrification rate was affected by soil pH and nitrifying microbial community composition. AbstractNitrification in the rhizosphere is a crucial process in controlling nitrogen-use efficiency (NUE) in flooded paddy soils. To understand the relationship between the nitrification ability of the rhizosphere and NUE, pot experiments using15N tracer technique wer...

CropBooster ‐P: Towards a roadmap for plant research to future‐proof crops in Europe
The H2020 CropBooster-P project is a research initiative led by a consortium of European universities and research institutes to prepare a roadmap for the development of improved crops to future-proof European agriculture. To do so, the CropBooster-P project has five work packages (WPs), each with their own goal. In this way, we could identify and recommend routes for the future development of crops that wil meet future food and sustainability challenges in ways that are most beneficial to, and accepted by, society. AbstractThe world needs more than double its current agricultural productivity by 2050 to produce enough foo...
