Metabolomics and Transcriptomics Analyses Reveal Regulatory Networks Associated with Fatty Acid Accumulation in Pecan Kernels.
Pecans are a globally important tree nut crop. Pecan nuts are rich in fatty acids (FAs), proteins, and flavonoids in addition to thiamine and numerous micronutrients. Although several of these nutriments have been studied in this plant, the comprehensive metabolite variations and molecular mechanisms associated with them have not been fully elucidated. In this study, […]
First report of Fusarium concentricum as a causal agent of Fusarium leaf blotch on pecan (Carya illinoinensis) in Southeast China.
The economically important nut crop pecan (Carya illinoinensis (Wangenh.) K. Koch) is seriously affected by increasing incidence of fungal disease worldwide (Xiao et al 2021). The top leaves of the pecan variety ‘Pawnee’ in the orchard of Zhejiang A&F University, Zhejiang, China were damaged by massive dark brown plaques in summer to autumn 2021. The […]
Pecan-enriched diet improves cholesterol profiles and enhances postprandial microvascular reactivity in older adults.
Pecan-enriched diets have been linked to improved lipid metabolism; however, the impact of pecans on vascular health has yet to be examined. We hypothesized that 4 weeks of a pecan-enriched diet would improve fasting and postprandial blood lipids and vascular function compared with a nut-free diet. In this randomized control study, 44 older adults (59 […]
First report of leaf spot on pecan caused by Choanephora cucurbitarum in China.
Pecan (Carya illinoinensis K. Koch) is an important and widely planted nut tree species in Jiangsu Province, China (Mo et al. 2018). In July 2020, leaf spot symptoms were frequently observed on pecan in Jurong, Jiangsu Province (119°15’36″E, 32°1’6″N). Disease incidences ranged from 40 to 65% among 150 mature pecan trees from three nurseries. The […]
One-class model with two decision thresholds for the rapid detection of cashew nuts adulteration by other nuts.
A green screening method to determine cashew nut adulteration with Brazilian nut, pecan nut, macadamia nut and peanut was proposed. The method was based on the development of a one-class soft independent modelling of class analogy (SIMCA) model for non-adulterated cashew nuts using near-infrared (NIR) spectra obtained with portable equipment. Once the model is established, […]
Pecan agroforestry systems improve soil quality by stimulating enzyme activity.
Background: Forest and plantation intercropping are efficient agroforestry systems that optimize land use and promote agroforestry around the world. However, diverse agroforestry systems on the same upper-plantation differently affect the physical and chemical properties of the soil. Methods: The treatments for this study included a single cultivation (CK) pecan control and three agroforestry systems (pecan + Paeonia suffruticosa + Hemerocallis […]
Effect of thermal annealing and filler ball-milling on the properties of highly filled polylactic acid/pecan (Carya illinoinensis) nutshell biocomposites.
Biodegradable polymer composites reinforced with agri-food lignocellulosic biowaste represent cost-effective and sustainable materials potentially able to replace traditional composites for structural, household, and packaging applications. Herein, the preparation of polylactic acid (PLA)/pecan nutshell (PNS) biocomposites at high filler loading (50 wt.%) is reported. Moreover, the effect of two environmentally friendly physical treatments, namely ball-milling of […]
Characterization and expression analysis of the SPL gene family during floral development and abiotic stress in pecan (Carya illinoinensis).
SQUAMOSA promoter binding protein-like (SPL) genes are a type of plant-specific transcription factors that play crucial roles in the regulation of phase transition, floral transformation, fruit development, and various stresses. Although SPLs have been characterized in several model species, no systematic analysis has been studied in pecans, an important woody oil tree species. In this […]
Effect of pecan nuts and extra-virgin olive oil on glycemic profile and nontraditional anthropometric indexes in patients with coronary artery disease: a randomized clinical trial.
The influence of cardioprotective foods on nontraditional indexes related to dysglycemia and body fat distribution is unknown in individuals with coronary artery disease (CAD). This study aimed to evaluate the effect of a healthy diet supplemented with pecan nuts or extra-virgin olive oil on glycemic profile and adipose tissue dysfunction assessed by anthropometric indexes in […]
Pecan-enriched diets decrease postprandial lipid peroxidation and increase total antioxidant capacity in adults at-risk for cardiovascular disease
Pecans are a rich source of antioxidants, but the effect of regular consumption on post-meal responses is unknown. The objective of this study was to examine the impact of daily pecan consumption for 8 weeks on fasting and postprandial lipid peroxidation, total antioxidant capacity (TAC), and tocopherols in adults at higher risk for cardiovascular disease […]
