Abstract
This study examines the key factors that determine the preferences of US consumers towards the growing and processing used for horticultural products such as fruit, vegetables, wine and beer over their preferences for buying them both before and after the COVID-19 pandemic. The findings obtained using Partial Least Square Structural Equation Modeling (PLS-SEM) show that engagement with horticulture prior to and after the occurrence of COVID-19 influenced preferences for the growing and processing of fruit, vegetables, wine and beer over buying them in both the pre-COVID-19 and post-COVID-19 contexts. Engagement with horticulture before and after the COVID-19 pandemic was significantly impacted by attitudes towards US growers. Attitudes towards COVID-19 and human values such as self-enhancement, conservation and self-transcendence were also found to be significant factors, while openness to change was not found to be significant. Best practice recommendations are included on the basis of these findings for managers of community gardens, horticultural properties and specialized food stores.

Abstract
The flux, distribution, and storage of soluble sugars regulate crop yield in terms of starch, oil, protein, and total carbohydrates, and affect the quality of many horticultural products. Sugar transporters contribute to phloem loading and unloading. The mechanisms of phloem loading have been studied in detail, but the complex and diverse mechanisms of phloem unloading and sugar storage in sink organs are less explored. Unloading and subsequent transport mechanisms for carbohydrates vary in different sink organs. Analyzing the transport and storage mechanisms of carbohydrates in important storage organs, such as cereal seeds, fruits, or stems of sugarcane, will provide information for genetic improvements to increase crop yield and fruit quality. This review discusses current research progress on sugar transporters involved in carbohydrate unloading and storage in sink organs. The roles of sugar transporters in crop yield and the accumulation of sugars are also discussed to highlight their contribution to efficient breeding.

Abstract
Due to the increasing frequency of wildfires in recent years, there is a strong need for developing mitigation strategies to manage the impact of smoke exposure of vines and occurrence of ‘smoke taint’ in wine. One plausible approach would be to prevent or inhibit the uptake of volatile phenols from smoke into grape berries in the vineyard. In this study we describe a model system we developed for evaluating under controlled conditions the effectiveness of a range of surface coatings (including existing horticultural sprays) for reducing/preventing the uptake of volatile phenols and their subsequent conversion to phenolic glycosides. Grapes were coated with the materials to be tested and then exposed to gaseous phenols, via evaporation from an aqueous solution, in a semi-closed glass container. Analysis of volatile phenols and their glycosidic grape metabolites demonstrated that the treatments typically did not provide any significant protection; in fact, some resulted in higher concentrations of these compounds in the grapes. The highest concentrations of volatile phenols and their glycosides were observed after application of oily, hydrophobic materials, suggesting that these materials may enhance the adsorption or transfer of volatile phenols into grape berries. Therefore, it is important to consider the types of sprays that are being applied in the vineyard before and during smoke events to prevent the potential of exacerbating the uptake of smoke compounds by grape berries.

Abstract
This study aimed to develop a checklist for good hygiene practices (GHP) for raw material of vegetable origin using the focus groups (FGs) approach (n = 4). The final checklist for commercialization of horticultural products totaled 28 questions divided into six blocks, namely: water supply; hygiene, health, and training; waste control; control of pests; packaging and traceability; and hygiene of facilities and equipment. The FG methodology was efficient to elaborate a participatory and objective checklist, based on minimum hygiene requirements, serving as a tool for diagnosis, planning, and training in GHP of fresh vegetables, besides contributing to raise awareness of the consumers' food safety. The FG methodology provided useful information to establish the final checklist for GHP, with easy application, according to the previous participants' perception and experience.
