Quantitative trait locus (QTL) mapping and transcriptome profiling identify QTLs and candidate genes associated with heat stress response during reproductive development in Camelina sativa
AbstractCamelina sativa (L.) Crantz is a low-input oilseed crop that has great potential in providing sustainable feedstock for biofuels and bioproducts. Climate change is threatening production of camelina with rising global temperatures. Elucidating the genetic response to high temperatures is essential for successful breeding of heat-tolerant camelina varieties. Here, we report a combinatorial approach to identifying candidate genes associated with heat stress by quantitative trait locus (QTL) mapping and comparative transcriptome profiling. A population of recombinant inbred lines (RILs) was grown in a controlled growt...

Recruiting grape ‐isolated antagonistic yeasts for the sustainable bio‐management of Botrytis cinerea on grapes
This study examined three grape-isolated yeasts (Metschnikowia aff.fructicola,Metschnikowia pulcherrima, andHansenispora uvarum) throughin vitro andin vivo tests on detached grape berries against grey mould, as well as the elucidation of their possible mechanisms of action. The antifungal mechanism of action of yeasts was determined by the lytic enzyme activity, inhibition of spore germination, biofilm activity, iron depletion, diffusible metabolites, wound-site colonisation, mycocin, and volatile organic compounds (VOCs) production. The highestin vitro efficacy (83.13%) was observed onM. aff.fructicola, followed byM...

Climate change and livestock production in Sub ‐Saharan Africa: Effects and transmission channels
This article assesses the effect of climate change on livestock production in Sub-Saharan Africa, for a sample of 45 countries over the period 2000 –2021. Using a two-factor fixed effects panel data model, our results obtained by the two-way fixed effects estimator show that (i) climate change negatively influences livestock production through high temperatures, while abundant rainfall is beneficial. (ii) Through transmission channels, we fin d that maize price volatility exacerbates the negative effect of rising temperatures on livestock production, while it reduces the beneficial effect of abundant rainfall. Furthermor...

Effects of pesticide treatment against nematode disease on soil bacterial community structure and sweet potato yield and quality
In this study, Illumina MiSeq high-throughput sequencing technology was used to analyze the diversity of soil bacterial and fungal communities treated with different pesticides. At the same time, high performance liquid chromatography was used to determine the pesticide residues in soil and sweet potato, and the impact on sweet potato yield was investigated. Kruskal –Wallis test was used to analyze the four α-diversity indexes of soil under different pesticide treatments, and the differences were not significant (p > 0.05), indicating that there was no significant difference in the diversity and abundance of bac...

Genome ‐wide association studies for rice seed germination under drought stress using 3VmrMLM
In this study, a genome-wide association study (GWAS) was conducted to determine the genetic basis of seed germination under drought stress in a panel of 165 rice accessions using a multi-locus compressed variance-component mixed model, 3VmrMLM. A total of 33 quantitative trait nucleotides (QTNs) were identified in association with drought tolerance during seed germination. Around these QTNs, eight were found to be co-localized with known drought-related genes. Furthermore, a causal candidate gene,OsGA2ox5, which encodes a gibberellin (GA) 2-oxidase, was identified forQTN-Chr07_242906 by integrating linkage disequilibrium ...

The estimation of wheat yield combined with UAV canopy spectral and volumetric data
This study bridges this gap by utilizing unmanned aerial vehicle (UAV) multispectral imaging to capture images and elevation data of wheat at key developmental stages —gestation and flowering stages. We innovatively leveraged the elevation differences between these stages to calculate canopy height, develop a novel CVF, and refine the wheat yield prediction model across various wheat varieties, nitrogen fertilizer levels, and planting densities. The integration of canopy volume information significantly enhanced the accuracy of our yield prediction model, as evidenced by anR2 of 0.8380, an RMSE of 313.3 kg/ha, and an ...

Impact of managing yellow rust (Puccinia striiformis f.sp. tritici) by the use of fungicide sprays and resistant varieties on the physiochemical qualities of bread wheat
AbstractYellow rust disease caused byPuccinia striiformis f. sp.tritici is one of the major threats to wheat production in Ethiopia. In this paper, the impact of yellow rust on the physical qualities of bread wheat was studied. For this purpose, combinations of four bread wheat varieties (Digalu, Hidase, Danda'a, and Honkolo) and two fungicides (Nativo SC 300 and Tilt ® 250E.C.) were tested at two different hotspot areas (Albazar and Alicho) in the Silte Zone, Southern Ethiopia, under natural epidemics of the disease during the 2018 growing season. A randomized complete block design in factorial arrangement with three rep...

Determinants of the accuracy of using carbon isotopes in estimating water use efficiency of selected cereal and legume crops: A global perspective
AbstractField assessments of crop water use efficiency (WUE) are resource-consuming since they require simultaneous assessment of the total amount of water assimilated by crops for biomass and/or grain production. Alternative methods exist, such as estimating the carbon isotopic ratio (13C/12C) of the crop's leaf, aboveground biomass, or grain samples. There is limited information on the determinants of the accuracy of carbon isotopes in estimating water use efficiency between crop types and environments. Therefore, this study aimed to evaluate the extent to which the estimation of the13C/12C ratio in crop parts constitute...

Unveiling the resilience of smallholder farmers in Senegal amidst extreme climate conditions
This study aims to determine the resilience of different agronomic interventions for farmers practicing mixed farming that produce both crops (i.e., groundnut (Arachis hypogaea L.) and pearl millet (Pennisetum glaucum (L.) R. Br.)) and raise animals in the Groundnut Basin in Senegal, which holds historical and socioeconomic significance. To understand the current situation regarding demographics, economics, consumption behavior, and farm operations for smallholder farmers, data were comprehensively collected from government and nongovernment organizations (NGO) reports, scientific papers, organization databases, and survey...

The application of biochar improves the nutrient supply efficiency of organic fertilizer, sustains soil quality and promotes sustainable crop production
AbstractRapeseed meal, a nutritious organic fertilizer (OF), contributes to improving soil environment and crop productivity. However, there are also problems, namely slow fertilizer efficiency and low nutrient utilization during the growing season. This 2-year field trial was conducted to explore the effect of biochar addition on improving the nutrient availability of OF through a comparative study of various biochar application rates under rice-rapeseed rotation conditions. The findings revealed that, compared to the individual application of chemical fertilizers (CF), OF alone decreased rice yield (2%/2%) and rapeseed y...

Biomass ‐based lateral root morphological parameter models for rapeseed (Brassica napus L.)
AbstractLateral roots, including adventitious roots, are the main component of rapeseed roots with support, absorb, and synthesis functions and their morphological parameters directly affecting the plant's aboveground growth and yield. Root biomass, as a material base for lateral root growth, can be used as a link between plant phenotypes and their physiological processes, as well as to enhance root 3D growth model mechanisms and accuracy. To quantify the relationships between lateral root morphological indices and the corresponding organ biomass for rapeseed, we used two cultivars, NY 22 (conventional) and NZ 1818 (hybrid...
