The aim of this study was to investigate the role of tocopherols in the susceptibility of Star Ruby grapefruit to postharvest chilling injury (CI). Fruit exposed to normal sunlight (NC, non-covered) and deprived of light (C, covered) in the last stages of development were used. Tocopherol contents increased in the flavedo of both NC and C fruit during development, concomitantly with the up-regulation of and most genes of the tocopherol-core pathway. Fruit shading reduced total contents by repressing γ-tocopherol accumulation, associated to a down-regulation of and and, to a lesser extent, of , and . During cold storage, total and α-tocopherol contents increased in NC and C fruit, and no direct relationship between tocopherol accumulation and CI tolerance was found. Cold stress up-regulated most genes involved in the synthesis of tocopherol precursors and down-regulated those of the tocopherol-core pathway, but changes seemed to be cold-mediated and not related to CI development.

Seed endophytes are actively used by the mother plant as both reservoir and vector of beneficial microbes. During seed dormancy endophytes experience significant physiochemical changes and only competent endophytes could colonise successfully in seeds and some of them act as obligate endophyte that are transmitted vertically across generations. The adaptive nature of endophytes allows them to switch lifestyles depending on environment and host conditions.

Wild edible trees (WETs) play an important role in the diet of many rural communities. Therefore, research on their use and management is important to support both food sovereignty and local conservation of biocultural resources. We evaluated the different uses of WETs by the community of Zacualpan, Colima, in western Mexico, through 32 semi-structured interviews registering the species richness, plant parts consumed, and non-food uses.

, a genus in the family Botryosphaeriaceae, has a broad host range and causes dieback, root rot, fruit rot, leaf rot, and blights in many plant species across sub-tropical and tropical geographical areas (Alves et al., 2008). In palms, this fungal pathogen is known to cause fruit and heart rot, wood decay and leaf blight around the globe (Atallah et al.

The rapid loss of viability, coupled with the difficulties and limitations in conserving coffee seeds, are some of the challenges that nurseries are currently facing. Thus, the objective of this work was to analyze the physiological quality of stored Arabica coffee seeds from cultivars recommended for planting in Brazilian mountainous regions. Seeds from 10 Arabica coffee cultivars were used: Catucaí-785/15, Catucaí-2SL, Catucaí-24/137, Japan, Arara, Acauã, Catuaí IAC-81, Mundo Novo IAC-379/19, Catuaí IAC-62, and Caturra IAC-479.

Aim: This study evaluated effects of various solutions on color stability and surface hardness of a nanohybrid dental composite in simulated oral environments.
Materials And Methods: Sixty-four composite disks were fabricated and randomly allocated into eight groups ( = 8 per group): Artificial saliva (AS), Biotene (B), passion fruit juice (PFJ), orange juice (OJ), Sprite (S), Coca-Cola (CO), apple cider vinegar (ACV), and cranberry juice (CJ). Specimens were immersed in respective solutions at 37°C for 28 days.
