Article Abstract
Cassava (Manihot esculenta Crantz) production will need to be improved to meet future food demands in Sub-Saharan Africa. The selection of high-yielding cassava cultivars requires a better understanding of storage root development. Additionally, since future production will happen under increasing atmospheric CO concentrations ([CO ]), cultivar selection should include responsiveness to elevated [CO ]. Five farmer-preferred African cassava cultivars were grown for three and a half months in a Free Air CO Enrichment experiment in central Illinois. Compared to ambient [CO ] (~400 ppm), cassava storage roots grown under elevated [CO ] (~600 ppm) had a higher biomass with some cultivars having lower storage root water content. The elevated [CO ] stimulation in storage root biomass ranged from 33% to 86% across the five cultivars tested documenting the importance of this trait in developing new cultivars. In addition to the destructive harvests to obtain storage root parameters, we explored ground penetrating radar as a nondestructive method to determine storage root growth across the growing season.

The polyunsaturated fatty acids in fish oil are prone to oxidation and have poor dispersibility, which limits their use in the food sector. In this work, oil-in-water emulsions stabilized by chitin nanocrystals (ChNC) were prepared via high-speed homogenization. Anionic carboxymethyl cellulose (CMC) was assembled onto cationic ChNC-stabilized emulsion droplet surfaces via layer-by-layer self-assembly technology to construct ChNC/CMC (Ch-C) bilayer emulsions with rigid inner layer and flexible outer shell structures.

Shrubs are perennial, multi-stemmed woody plants whose adaptation to stress factors allows them to colonise extreme habitats, including high elevations. Accordingly, shrubs are one of the most important growth forms in mountain regions, but their hydraulic properties are poorly understood. We conducted a literature search on the water use strategies of mountain shrubs, focusing on their main hydraulic traits related to water uptake, transport and release, as well as hydraulic limitations in summer and winter.

Camellia chekiangoleosa is a significant oil-bearing tree species, known for its high oleic acid content and shorter reproductive cycle compared to traditional oil-tea plants. However, there are few studies on the molecular mechanism and compatibility of the interaction between oil-Camellia scion and rootstock, which poses certain challenges to the cultivation and promotion of oil-Camellia. This study systematically evaluates the effects of hetero-grafting Camellia chekiangoleosa scions onto divergent rootstocks (Camellia chekiangoleosa, Camellia oleifera, and Camellia yuhsienensis).

The USDA-Agricultural Research Service conducted deficit irrigation and water productivity field trials for irrigated sunflower () in northeastern Colorado from 2008 to 2016. The dataset from these field trials, composed of 10 Excel spreadsheet workbooks, is available online from the USDA National Agricultural Library "Ag Data Commons". The dataset includes measurements of irrigation, precipitation, soil water storage, and periodic plant responses; daily estimates of crop evapotranspiration; and seasonal crop water use, biomass, and yield data.

The lipids and proteins that comprise lipid droplets regulate several cellular functions including lipid storage, stress responses, and inflammation. Glial lipid droplets have been implicated in the pathogenesis and progression of Alzheimer's disease (AD), yet the mechanisms linking genetic risk to lipid droplet biology remain unclear. Here we examined how , the strongest genetic modulator of late-onset AD, impacts lipid droplet composition and dynamics.
