Abstract Flooded plants experience impaired gas diffusion underwater, leading to oxygen deprivation (hypoxia). The volatile plant hormone ethylene is rapidly trapped in submerged cells and instrumental for enhanced hypoxia acclimation. However, the precise mechanisms underpinning ethylene-enhanced survival remain unclear. We studied effect of pretreatment on Arabidopsis (Arabidopsis thaliana) primary root tips. Both itself re-oxygenation following are highly damaging tip cells, pretreatments...
Oleaginous microalgae represent a valuable resource for the production of high-value molecules. Considering importance omega-3 long-chain polyunsaturated fatty acids (LC-PUFAs) human health and nutrition yields eicosapentaenoic acid (EPA) docosahexaenoic (DHA) require significant improvement to meet demand; however, current cost remains high. A promising approach is metabolically engineer strains with enhanced levels triacylglycerols (TAGs) enriched in EPA DHA.Recently, we have engineered...
Realistic targets for soil organic carbon (SOC) concentrations are needed, accounting differences between soils and land uses. We assess the use of SOC/clay ratio this purpose by comparing changes over time in (a) National Soil Inventory England Wales, first sampled 1978-1983 resampled 1994-2003, (b) two long-term experiments under ley-arable rotations on contrasting East England. The results showed that normalising clay concentration provides a more meaningful separation uses than SOC...
Summary The N‐end rule pathway of targeted protein degradation is an important regulator diverse processes in plants but detailed knowledge regarding its influence on the proteome lacking. To investigate impact Arg/N‐end etiolated seedlings, we used terminal amine isotopic labelling substrates with tandem mass tags ( TMT ‐ TAILS ) for relative quantification N‐terminal peptides prt6 , Arabidopsis thaliana mutant lacking E3 ligase PROTEOLYSIS 6 PRT 6). identified over 4000 unique representing...
In arable fields, plant species richness consistently increases at field edges. This potentially makes the edge an important habitat for conservation of ruderal flora (or 'weeds') and invertebrates birds it supports. Increased diversity abundance weeds in crop edges could be owing to either a reduction agricultural inputs towards and/or spatial mass effects associated with dispersal from surrounding landscape.We contend that weed is combination resident species, can persist under intense...
The transgene-directed accumulation of non-native omega-3 long chain polyunsaturated fatty acids in the seed oil Camelina sativa (Camelina) was evaluated field, distinct geographical and regulatory locations. A construct, DHA2015.1, containing an optimal combination biosynthetic genes, selected for experimental field release UK, USA Canada, eicosapentaenoic acid (EPA) docosahexaenoic (DHA) determined. occurrence these different triacylglycerol species monitored found to follow a broad trend...
Increasing the abundance and diversity of carabid beetles is a common objective farm habitat management to deliver sustainable pest control. Carabid spatial distributions in relation crop areas are important delivery this ecosystem service. We used pitfall count data at distances from edge habitats into centres, sites across UK, determine effects in-field adjacent environmental features on diversity. Overall increased towards centre, whilst species richness decreased. The analyses based all...
Abstract Genetic studies increasingly rely on high-throughput phenotyping, but the resulting longitudinal data pose analytical challenges. We used canopy height from an automated field phenotyping platform to compare several approaches scanning for quantitative trait loci (QTLs) and performing genomic prediction in a wheat recombinant inbred line mapping population based up 26 sampled time points (TPs). detected four persistent QTLs (i.e. expressed most of growing season), with both...
Expert opinion is increasingly being used to inform Bayesian Belief Networks, in particular define the conditional dependencies modelled by graphical structure. The elicitation of such expert remains a major challenge due both quantity information required and ability experts quantify subjective beliefs effectively. In this work, we introduce method designed initialise probability tables based on small number simple questions that capture overall shape distribution before enabling refine...
Dietary fibre (DF) has multiple health benefits and wheat grains are major sources of DF for human health. However, is depleted in white flour which more widely consumed than wholegrain. The component the cell wall polysaccharide arabinoxylan (AX). We have identified Chinese cultivar Yumai 34 as having unusually high contents AX both water-soluble insoluble forms. therefore used populations generated from crosses between four other cultivars, three with average (Ukrainka, Altigo Claire) one...
Soybean (Glycine max) offers an important source of plant-based protein. Currently much Europe's soybean is imported, but there are strong economic and agronomic arguments for boosting local production. grown in central eastern Europe less favoured the North due to climate. We conducted field trials across three seasons two sites UK test viability early-maturing varieties used data from these calibrate validate Rothamsted Landscape Model. Once validated, model was predict probability would...
Amino acids are delivered into developing wheat grains to support the accumulation of storage proteins in starchy endosperm, and transporters play important roles regulating this process. RNA-seq, RT-qPCR, promoter-GUS assays showed that three amino acid differentially expressed endosperm transfer cells ( TaAAP2 ), TaAAP13 aleurone embryo grain TaAAP21 respectively. Yeast complementation revealed all can transport a broad spectrum acids. RNAi-mediated suppression expression did not reduce...
Farm typologies are often used to reduce the complexity in categorising diverse farming systems, particularly sub-Saharan Africa. The resulting can then be multiple ways including designing efficient sampling schemes that capture diversity smallholder farms, prescribing selection of certain farm types which interventions targeted or upscaled, give context into derived relationships. However, construction consists many subjective decisions not always obvious evident end-user. By developing a...
Farmers face the challenge of increasing production to feed a growing population and support livelihoods, whilst also improving sustainability resilience cropping systems. Understanding key factors that influence farming management practices is crucial for determining farmers' adaptive capacity willingness engage in cooperative strategies. To end, we investigated farmers adopt underlying decision-making. We aimed identify constraints impede adoption strategies perceived increase explore how...
Lipids affect the quality of wheat flour for breadmaking. One possible mechanism is stabilization gas cells which are formed during dough mixing and expanded fermentation, leading to a greater loaf volume evenness texture. We therefore compared lipidomic profiles liquor fractions (which contain surface-active components present at bubble interface) from two sets lines differing in allelic variation QTL volume. Analyses three field trials showed consistent increases contents galactolipids...

However, farming systems are highly variable Ethiopia due to different soil types landscape cropping positions. availability uptake by plants from fertilizer sources governed retention release potential soil, usually termed as adsorption desorption, respectively. The aim this study was characterize amount plant available Zn at During 2018/19 season,...
Abstract The Arg/N-end rule pathway of ubiquitin-mediated proteolysis has multiple functions throughout plant development, notably in the transition from dormant seed to photoautotrophic seedling. PROTEOLYSIS6 (PRT6), an N-recognin E3 ligase regulates degradation transcription factor substrates belonging Group VII Ethylene Response Factor superfamily (ERFVIIs). It is not known whether ERFVIIs are associated with all rule, and downstream pathways influenced by fully defined. Here, we examined...
