Research outputs 2022 to 2026

Plants experience constant exposed to diverse abiotic stresses throughout their growth and development stages. Given the burgeoning world population, abiotic stresses pose significant challenges to food and nutritional security. These stresses are complex and influenced by both genetic networks and environmental factors, often resulting in significant crop losses, which can reach as high as fifty percent. To mitigate the effects of abiotic stresses on crops, various strategies rooted in crop improvement and genomics are being explored. In particular, the utilization of biostimulants, including bio-based compounds derived from plants and beneficial microbes, has garnered considerable attention. Biostimulants offer the potential to …

Proteomic Exploration Reveals A Metabolic Rerouting Due To Low Oxygen During Controlled Germination Of Malting Barley (Hordeum Vulgare L.), Clare E. O'Lone, Angéla Juhász, Mitchell Nye-Wood, Hugh Dunn, David Moody, Jean-Philippe Ral, Michelle L. Colgrave

Research outputs 2022 to 2026

Barley (Hordeum vulgare L.) is used in malt production for brewing applications. Barley malting involves a process of controlled germination that modifies the grain by activating enzymes to solubilize starch and proteins for brewing. Initially, the grain is submerged in water to raise grain moisture, requiring large volumes of water. Achieving grain modification at reduced moisture levels can contribute to the sustainability of malting practices. This study combined proteomics, bioinformatics, and biochemical phenotypic analysis of two malting barley genotypes with observed differences in water uptake and modification efficiency. We sought to reveal the molecular mechanisms at play during controlled germination …

1 H-Cyclopropa[B]Naphthalene: A Novel Ethylene Antagonist For Extending Storage Life And Maintaining Quality Of Climacteric And Suppressed Climacteric Plums, Poe N. Kyaw, Zora Singh, Vijay Y. Tokala

Research outputs 2022 to 2026

Ethylene is a key trigger that governs the rate of fruit ripening, storability, and postharvest quality of fresh fruit. Efficient inhibition of ethylene action is essential to slow down the postharvest ripening processes, extend storage life and maintain optimum fruit quality during storage. Ethylene antagonist compounds with the likelihood of application as liquid formulation would facilitate managing ethylene broadly as both preharvest and/or postharvest treatments. This study examined the effects of different aqueous formulations of 1 H-cyclopropa[b]naphthalene (NC) as an ethylene antagonist in the cold stored (1 °C) Japanese plums ‘Angeleno’ (suppressed-climacteric) and ‘Tegan Blue’, which exhibit climacteric peaks, respectively. …

Trends In Maintaining Postharvest Freshness And Quality Of Rubus Berries, Hafiz Muhammad Shoaib Shah, Zora Singh, Jashanpreet Kaur, Mahmood Ul Hasan, Andrew Woodward, Eben Afrifa-Yamoah

Research outputs 2022 to 2026

Blackberries and raspberries, commonly known as Rubus berries, are commercially grown worldwide across different climates. Rubus berries contain wide array of phytochemicals, vitamins, dietary fibers, minerals, and unsaturated fatty acids. Nevertheless, these berries have short storage life which is the major constraint in their supply chains leading to higher postharvest losses. Inappropriate harvest handling, physical bruising, insect pests, and postharvest diseases lower the acceptability of fruit among consumers and other supply chain stakeholders. Additionally, the susceptibility to microbial decay, fruit softening, higher ethylene production, respiratory activity, and increased oxidation of anthocyanins, phenolics, and flavonoids considerably affects the marketability of Rubus …

Experiences With Covid-19 Stress Among Hispanic/Latino Farmworkers, Brenda Berumen-Flucker, Hadiza Galadima, Sylvia Shangani, Michele Kekeh, Muge Akpinar-Elci

Community & Environmental Health Faculty Publications

BACKGROUND: Hispanics/Latinos, particularly those that identify as foreign-born, are overrepresented in the agricultural sector in the U.S. Over the course of the COVID-19 pandemic, this subpopulation of farmworkers was recognized as an invaluable group of essential workers unable to implement COVID-19 protections.

METHODS: Previously validated COVID-19 stress scale measures were identified, adapted, and translated to collect COVID-19 stress data from Hispanic/Latino agricultural workers in two heavily agricultural counties in northeastern North Carolina. Participants were recruited using purposive convenience sampling. Data collection took place from June to November of 2021.

RESULTS: The majority of Hispanic/Latino agricultural workers surveyed reported experiencing worries …

Faculty Publications - Agriculture

Objectives

To mitigate mental health concerns of farmers, research is needed to investigate strategies that encourage help-seeking behavior in this population. This study attempts to identify those help-seeking strategies. Six mental health service options were examined.

Methods

A survey, implementing a best-worst scaling choice experiment, was disseminated to members of the Illinois Milk Producers Association. Two methods of analysis were conducted. The first, a count-based method, employs a simple count-based approach to measure the relative preferences for the six mental health service options in question. The second is more complex and employs a latent-class logit regression model to measure individual …

Wa Avocado Life Cycle Analysis (Lca), Christophe D'Abbadie, Saloomeh Akbari
