The hypotensive effects of Vaccinium ashei reade (blueberry) leaves were studied in vitro and in vivo. Blueberry leaf showed a strong inhibitory effect on angiotensin-converting enzyme activity in vitro. Additionally, feeding of blueberry leaf suppressed the development of essential hypertension in spontaneously hypertensive rats in vivo. These results promise the use of blueberry leaf as a source of dietary hypotensive components.

Botryosphaeria stem blight is a fungal disease of blueberry caused by members of the Botryosphaeriaceae family, which can lead to rapid wilting of leaves and stems, often resulting in significant yield loss and even plant death. Botryosphaeria stem blight is a major disease in Alabama, however, information on the distribution and causal pathogens for stem blight in Alabama is limited. This study surveyed blueberry farms in Alabama and nearby parts of Georgia and Mississippi to reveal the occurrence, species identities, and virulence of causal pathogens for Botryosphaeria stem blight.

Nuclear Factor Y A (NF-YA) transcription factors are widely involved in multiple plant biological processes, such as embryogenesis, abscisic acid signaling, and abiotic stress response. This study presents a comprehensive genome-wide identification and expression profiling of NF-YA transcription factors in blueberry (), an important economic crop with good adaptability, under abiotic stress conditions. Given the economic significance and health benefits of blueberries, understanding their responses to environmental stresses, such as salt, drought, and temperature extremes, is crucial.

Article Synopsis
  • Blueberries have a variety of anthocyanins that give them their blue color, and some types can produce more stable acylated anthocyanins, making them a focus for breeding.
  • This study focused on a specific gene, VcAAT1a, which was found to effectively produce different acylated anthocyanins in various plant systems.
  • The research identified that VcAAT1a only uses acetyl CoA as an acyl donor, and its promoter is activated by certain transcription factors, providing insight into how anthocyanin production is regulated in blueberries.

This study presents a novel rapid analytical method for the detection of volatile organic compounds (VOCs) emitted from blueberry leaves using the Tenax adsorbent followed by separation using a multicapillary column (MCC) and Ion Mobility Spectrometry (IMS) detection. The emitted VOCs including caryophyllene, benzene acetonitrile, linalool, ocimene, and methyl salicylate initiated by different stress factors including mechanical damage (punching), herbivore attack (aphids) and methyl jasmonate (MeJA) spraying were detected and quantified. Limits of Detection (LODs) for the VOCs were determined in the range of 8 to 33 ng.
